CentOS 5 :: 5.4 VNC Black Screen With Cursor
Jan 13, 2010
I decided to give a try to VNC server on my remote dedicated centos machine. WHAT I DID:
yum groupinstall "X window system"
yum groupinstall "GNOME Desktop Environment"
yum install vnc-server
Followed the Centos wiki tutorial.
PROBLEM: After typing the password in my vnc viewer I get a black screen with cursor. I can move the cursor about but thats it.
SOLUTION: I have googled like crazy for the last 2 days but have not found a solution yet. My best guess is xorg.conf file, but I am quite new to linux so could be wrong.

I turned on my Acer laptop and during bootup it seemed normal. After it passed the blue Acer logo, all I could see is a black screen and a black cursor outlined in white in the shape of an X. Thinking it would be a one time thing, I turned it off again.it still was a black screen.

I installed Ubuntu 11.04 today as the main OS on my laptop.I had deleted my XP partition, and repartitioned it according to a guide I had found. (http:url)......Basically it was setup like this: 500mb ext2 primary partition, has the grub folder, I believe this is either the '/' partition, or the '/boot' partition 2gb swap space logical partition
10gb ext4 logical partition -- this is either the '/' or the '/boot', it contains the 'bin,boot,cdrom,dev' etc folders 243gb (the rest of my hard drive, with the exception of a partition that contains documents and files from my XP OS, formatted to NTFS) ext4, this is the one that has all my desktop/documents/etc folders.After Ubuntu was done installing, I had some message pop up about installing an ATI proprietary driver for my ATI graphics card (an ATI Radeon HD 4330, I believe, I may have messed that number up). I installed it and rebooted, no problem.
Next, I had another update window pop up with 198 items checked and ready to download and install. I went through all of this, and rebooted, again, no problem.Next thing I did was install some apps that were essential for me to have to use for my work (an ide, chat programs, etc). No problem with any of that.Last thing to install was the OSE Virtualbox, and then I installed WindowsXP Pro and Windows Vista Business, then installed the guest addition addon for VB. This all worked without any issues whatsoever.
Time goes on, and I notice my computer is heating up much more than (seemingly) normal. I begin to wonder if its my graphics card. So I shut down the computer and let it cool down. Reboot, and no problem, still working fine.Then I opened a couple of apps and tried a simple game (can't remember the name) I believe it was a simple 3d topdown, as I wanted to test my graphics card. This is where things seemed to start to go wrong. My laptop began hanging, not even allowing me to access the terminal via ctrl+alt+f2. The screen flashed and I saw the blue/green/grey fuzz that I get when the graphics card is starting to heat up too much. Then everything hangs and I can't do anything at all, including move the mouse. I did a hard reboot (I believe this is what you call pulling the plug/pressing the power button, correct me if I'm wrong). I then rebooted, saw a chkdisk, then it booted seemingly normal, but it hung right after the purple screen after the grub screen.
This is pretty much where I'm at right now. I strongly suspect the fault is with the ATI drivers, but have been completely unsuccessful in my attempts to fix it. I've googled just about everything I could think of, along with searching these forums. I've tried just about everything listed in the forums, but to no avail.I've tried the commands that are supposed to purge the ati drivers, but all I get are errors that say they can't remove the 'virtual drivers'.
Right now I'm booting off a live cd, so I know the computer still works fine, just not my actual installed OS. I'd really like to get the issue resolved without having to reinstall, as it took quite awhile just to get it usable in the first place, but this has already taken so much time, I may just resort to that if we can't solve it any other way. Got too much work to catch up on as it is.As a re-instated note, perhaps if you have any tips, but not particularly about fixing the OS, my laptop (I'm strongly guessing my graphics card) is heating up much more than normal, compared to that when XP was installed. Is this more than likely just a driver issue, as is the rest of it? Also, I did have Compiz installed, though I didn't choose for it to be installed, I believe it came pre-installed. I've heard it could cause some issues, though I have no idea as to the validity or relation to this particular issue.
Edit:
I just remembered while searching for a solution, I found a post somewhere that said something about the information not being sent to the monitor from the graphics card properly, thus no desktop. I'm guessing that'd still fall under the driver issues, but again, I'm unsure. I would think that wouldn't be entirely true anyway, since I can still see my mouse fine, just no desktop, only a black screen.

Seems to happen with every version! I have the same problem as my last thread. Basically it was solved by removing an IPv6 line from the hosts file or adjusting the vnc configuration to use an IP and not host name. Both of these are not working for me on 11.3. I'm not seeing any errors in log/messages. It just sits there with an X cursor that moves around then times out after around a minute or so. I don't know if there are any other logs that will help.
To clarify, starting a vncserver from a terminal will work, but the 'Remote administration' vnc with the login screen will produce a fully black screen with an X cursor that updates with my mouse position.

Just did a fresh Ubuntu 10.10 (minimal) install on my Asus EEE PC 1001PX.Before the minimal install I had Ubuntu Netbook Edition 10.10 which worked flawlessly, now all I get is a black screen with a blinking cursor:for the amazing quality, but I guess it's better than nothing.ctrl+alt+Fx does nothing, ctrl+alt+del reboots the computer.Booting with the usb-stick that was used for the install takes me to the login...

I installed some weeks ago Fedora 14 via burnt iso file downloaded from official Fedora site. It was working perfectly like a charm for me until yesterday when I tried to install zend server for PHP.During my first try of installation of zend server it corrupted out my apache server and I lost apache on http://localhost.I removed all "zend-server" like stuff from "Add Remove Software" screen.
Installed again apache 2 in the form of LAMP (Linux Apache Mysql Php)via terminal. Apache installed correctly and started workeing again ok on localhost.n again I tried to install zend server from install.sh file in downloaded zend server installation. It showed me after a while like "zend server installed successfully".I shut down my pc thinking everything is ok now.
Today when I started my system, it shows me boot screen of Fedora, I select fedora and then it shows me baloon filling up for around 5-7 secs. Then all of a sudden a black screen appears up with a cursor blinking at its top left and then nothing else happens further. I cannot find login screen to my desktop anymore.I remember one thing thating reinstallation of apache from terminal, I set following command like "chkconfig --level 235 httpd" (I guess that's what I have written as per some online tutorial for LAMP). Is that cause of mine problem ot its something else?

A few weeks ago I installed Ubuntu 10.4 beta on a pc. I upgraded it to 10.4 RC and 10.4 final release. I think it was after upgrading to 10.4RC that I started having a problem during startup. Here is what happens:
I turn the pc on the bootstrap process occurres, then the grub screen comes up I let ubuntu boot. For a few seconds I get a black screen with a blinking cursor. The Ubuntu splash screen flashes on the screen for maybe a second or two. Then I'm dumped to the command prompt on TTY1.
At this point I can log in with a username and password type startx and I'm at the ubuntu desktop. If I log off I'm back at the command prompt on TTY1. If I press alt-ctrl-F7 at the command prompt this is what I see, these are the last four lines of text: init: ureadahead-other main process (742) terminated with status 4

I have windows 7 + Ubuntu 10.04 in dual boot, I noticed that sometimes the ubuntu was not booting.
Right after I select the os in grub (ubuntu) the screen goes black with the blink cursor and nothing happens, that's all no messages it's stuck there forever.
Today, it does this every time I try to enter Ubuntu, it's just stuck there.

just did a dual boot install on a brand new DEll T1500. The machine has win7 on it. I booted off the live CD and all looked well. Installation went well. When I reboot, I get grub, select the top linux option and then see a small black blinking cursor for a few seconds, then nothing. The screen reports no signal.

I have installed Maverick onto an INTENSO 320GB USB Hard Disk. I can boot from GRUB, but only get a dark grey screen, with no cursor. I have tried editing the boot script, removing "quiet & splash" and putting in "nomodeset". I have also tried "i915.modeset=1" and "i915.modeset=0". Also "xforcevesa" and "nouveau.modeset=0". None have worked. I have not been able to reach a console screen to log in. Here are the specifications of the machine:
[Code]....
Are the number of spaces between "ro" and "quiet and splash" essential? There are three spaces on the boot script and I have left them there. Ubuntu works fine as a live CD, and I experienced no problems with the installation.

I am trying to do a dual boot of XP and ubuntu. I have 3 hard drives and I plan to put ubuntu on one of them. I have created a DVD from the ISO for 10.10 using programs and methods recommended by ubuntu, and it burned correctly onto the DVD. When I boot with the dvd in the tray the computer says something about linux iso then the screen goes black with a Human=Keyboard symbol at the bottom for a few seconds. Then my screen goes black with a blinking cursor in the top left of the screen. I have let it sit for a while and the PC shows no signs of drives working.Also if I remove it the PC automatically boots to windows.

I am installing Fedora 12 on a VIA pico ITX and am running into some issues.
I had the same board but with an PATA/IDE drive, and on that it installed just fine. I needed a bigger/better drive so I did get an SATA drive for it.
After the install it either freezes/hangs when the post install begins or IF the post install works (when I use ide=nodma) it won't boot. I do get to see the grub screen (if I change the timeout in grub.conf) but as soon as the kernel starts loading it freezes. and I see a black screen with a prett fast blinking cursor.
With the live cd, if I try to boot: it reports, no root available going to sleep.

Yesterday I done an upgrade with apt and since that time whenever I boot up I am presented with only a blank screen and an unresponsive cursor. I cannot switch console using Ctl+Alt+F*. The only thing I can do is Alt+SysRq+(R,E,I,S) which kills gdm3 and gets me back to the console.
* I can get into Xorg fine via the startx command
* As a temporary fix, if I enable automatic login (via /etc/gdm3/daemon.conf) then gdm3 works.
But I can't get the normal authenticated login screen to work.
Output of journalctl for a failed attempt at running gdm3 with verbose debugging enabled:
Code: Select allOct 25 01:24:43 [hostname-removed] systemd[1]: Starting GNOME Display Manager...
Oct 25 01:24:43 [hostname-removed] systemd[1]: Started GNOME Display Manager.

[Code] ....
One other thing worth noting, before upgrading yesterday, I changed mirrors and accidentally pasted in "stable" into /etc/apt/sources.list. So basically I did an initial upgrade, realised my mistake, switched back to testing (which I was on before) and done another upgrade, which is when I noticed this problem.

I have here two old identical compaq pc's with 64mb ram.I want to copy drive/os from one machine to other. So i do a drive to drive clone (witn both hd's deing connected to another machine). And it says its done and okay. But the second (cloned) machine doesnt boot. And have the black screen with the blinking white cursor in top left corner. I have already tried to do fdisk /mbr and also copying partition table from original to destination disk. Because i think it is logical that with a drive to drive clone it sould be copied. But i have a doubt in that somehow. Because why would it not boot if it was copied then

when I boot and login to a fresh install of Ubuntu, everything goes fine, the login screen appears, I login. Then the cursor appears on a black screen. This is normal. Then when the desktop should appear, on the very left edge of the screen, about 5 pixels in size, you can see the panel and the rest of the desktop. But I stress, You still see the cursor. In this small area, you can right click as you, even click on the menu and it will come down, you can see it. I can click on Ubuntu SC and the cursor will turn to a loading symbol. But then nothing again. I can press Ctrl + Alt + F2 and terminal will come on fine. So far, this has happened on a live CD of Maverick, A live USB of Maverick, A Natty Narwhal Fresh Install, A Maverick Fresh install, A Karmic Old Install and That same Karmic After going through a Distro upgrade via Ctrl + Alt + F2 to 11.04. I've gotten all the updates for all of them (A slow, bandwidth wasting process), and this doen't happen on other computers, even ones with lower graphics cards then mine. Additionally, on the same computer on a seperate partion, I can load my main Maverick just fine, Indicateing that it can't be a hardware problem. After searching across the internet, I'm at loss to an answer.

I have a problem with booting from a USB flash drive. I have Acer TimelineX 3820TG. I have Windows 7 Home from Acer and I installed Mandriva OS from USB(from USB because this Acer doen't have a DVD drive). It was OK, but I want reinstall Windows 7 and so I did. Now I have Windows 7 Professional and it wrote over Mandriva's GRUB. It wasn't a big problem. For a while I was just using Windows 7 but now I am thinking that I need some OS with Linux and I am thinking about Ubuntu. But when I tried to boot from USB with Ubuntu I get a black screen with a blinking cursor after the BIOS POST.
I was trying many applications to create a bootable USB drive and many versions of Ubuntu (and other Linux distributions), but nothing worked. I tried to Google for answers but I found many problems where all booting goes to black screen but in my problem Windows 7 boots fine from disc but from USB doesn't work.

Code:
# tty2 - getty

# This service maintains a getty on tty2 from the point the system is
# started until it is shut down again.
start on runlevel [23]

As the topic says. I'm having problem after problem, everytime I figure out a way to take a step forward, my PC has pre-emptively taken a step back.
I'm unable to boot to X or (recovery mode).
I did try booting to a LiveUSB in order to run update-grub, but then it occured I have no idea how to do this from a LiveUSB that will affect the internal HDD installation?
So I'm currently trying to reboot from Live USB, but that just seems to have locked up the PC on the white ubuntu logo. I'm afraid to hard reset it (been doing too much of that lately). How long should a Live USB take to shutdown? (been about 10 minutes so far ). It's not a persistent LiveUSB as far as I know, and I basically just booted to the desktop and then start the reboot cycle as soon as I realised I didn't know what I wanted to do .

I dual-boot Windows 7 and Ubuntu. Sometime between 4/18 and a few days ago, something happened with Windows booting up. Ubuntu boots fine, but whenever I try to boot Windows, it just goes to a black screen with a blinking cursor (the command line kind, not a pointer). At first I thought it was Windows, but I have run the repair CD and executed chkdsk /f and chkdsk /r on all partition related to windows. No effect.
I ran a system check designed for issues with booting up, and it found no errors. I have looked at my GRUB files, and they all look fine. I am not sure if it is GRUB or Windows. I tried reinstalling the Windows boot-loader, and it had the same effect, the only difference is that it bypassed GRUB. The reason I think it may be GRUB is that the error happened around the same time as me upgrading from Karmic to the Lucid RC. I have posted this on a Windows 7 forum.

I have an Acer Aspire One AOA110 that came with Windows XP.
I created a usb flash drive install for Ubuntu 10.10 netbook edition and went through the install process (wiped disk clean, not a dual boot with WINXP).
Before install, I was able to run Ubunut from the usb key with no problems.
At the end of the install, it told me I needed to restart, so I clicked the "restart" button and the removed the usb drive. Nothing happened and it never restarted and just completley hung for about 20 minutes. I manually shut down the computer by holding the power for 10 seconds and then rebooted the machine. Now all I get after the "acer bios" screen is a black screen with a blinking cursor. If I press any buttons, the computer beeps at me.

After installing Ubuntu Server 10.04 LTS, I restarted my machine. I removed the disk, but now when it starts, it never gets to GRUB. Instead, it just takes me to a black screen with a blinking cursor. I can't type in anything and holding shift doesn't take me to GRUB.

I have rebuild my system, with an Asus motherboard M4A88TD-V EVO/USB3 with radeon 4250 integrated 8 Gb memory
Athlon II 4x 640 2 x 1 TB sata3 WD Harddisks I installed 10.10 64bit, and ran through the whole install with the alternate CD without problems, Installed grub in the MBR on the 120 Gb partition for 10.10, it even recognised my 2 3ware pci raidcontroler on which 8.04 is installed.
When I start I get grub, when I choose for 10.10 I get a black screen with a cursor blinking in the left uppercorner. Luckily I can start into 8.04. I have no idea how to continu. for now I will burn a knoppix cd so I can read the ext4 partition with 10.10 and hope to find something to solve this.

I'm a fairly new linux user and I seem to have a problem with ubuntu 8.10 after installing it.To make sure everything was working fine before i could do a dual installation, i ran the live cd and it worked like a charm.Everything works fine in the live cd....the internet, sound, graphic drivers (even the special effects seemed to be work fine)I thought wow...after having a bitter experience with Ubuntu 8.04 and 7.10 (I couldnt install those at all coz of driver issues and stuff) I thought this is it!So I used the wubi installer to install ubuntu in my D drive (I didnt wanna use C just to be safe as the primary OS is installed there). Gave it a healthy space of 15 gb. Finished the installation and the rebooted.I went inside Ubuntu which started doing its installation and copying of files and stuff. So far so good.....
And then once it finished its installation and copying of files (100 %), the screen went blank and i see a cursor blinking. I thought maybe its restarting and thats why it must be doing this.I wait for nearly 10 mins and nothings happening except for the cursor blinking on the black screen. I press the caps lock key to see if anything is processing. Nope. So i manually shut it down and then load ubuntu.It loads like 20-30%....rests for a while....and then it loads a bit (not completley)....after that it takes me to a command line asking me for my password and username.I enter those correctly. But it doesnt get me into the main GUI screen yet.
It shows me a lot of the this error msg:
-bash: /dev/null:Permission denied
I'm still in command line (or terminal to be precise). So i use 'startx' (something which i learned from my csci labs ) to start a new session. It showed signs of starting a new session (i can see the mouse pointer and stuff) and then poof....back to the command line again.So I shut it down and load it again in recovery mode. It shows signs of the same symptoms in the splash screen (going very slow after 20-30 % ) and then this time, before i'm asked for my username and password in the command line, it shows a lot of warnings: fake daemon running (or something like that) and i cant even use startx!So i didnt know what to do, uninstalled ubuntu and did a fresh installation (wubi and in the same D drive). Reboot. Install and copy files 100% and then a blank screen again with the dreaded cursor blinking. I still wait for about 10 mins and nothing yet happens. So I manually shut it down (again) and then load ubuntu and unsurprisingly i have the same problem as what i described before....doesnt load properly and i'm not able to come out of the terminal.

Redhat Ent Linux ES Release 2 (Taroon 8)
Kernel 2.4.21-4.ELsmp
startx(1): initialize X session - Linux man page
I thought I'd look into methods of recovering from a lost password for future use, how to change the passwd and shadow should I need to. So I started an X session, vi'd my .swp files then logged off. Perhaps I changed one of these files accidentally, but my intent was just to view them which I did. After starting up my computer the next day and logging in I began an X session - "startx". The session appears to have started, but with a black screen and an active mouse cursor.

I was going to set up an ubuntu server, but ran into some issues. When I try to install ubuntu server 9.10, it immediately goes to a black screen with a blinking cursor as soon as I press enter on the menu. I've tried pressing F6 and editing options - noapic, nolapic, irqpoll, vga=[something...] and nothing worked. I then downloaded a standard ubuntu desktop cd, and the livecd works, and I can successfully start the install!
I've heard that I should probably use the server install if I want to use this as a server (which I do; webserver for a group of people, website, ftp, ssh.) I've also heard that it's possible to just install everything needed overtop of an ubuntu desktop base. What should I do? Are there other things I should try to make the server install work? Or is it not worth the effort, and I should just go with a desktop install and then work from there? tasksel? (It's a Dell XPS, the graphics card is NVIDIA Geforce 9800 GT).

I am trying to boot up Linux Mint 7 after a packages upgrade and it boots up but then it shows this and stalls.And similar messages for GDM and then it just shows a black screen with a single blinking cursor on the middle left of the screen. I cannot do anything except press the CTR-ALT-DEL combination to re-boot, then it shows the usual shutting down messages and does the re-boot.I am running the 2.6.28-19 kernel and I have upgraded the Ubuntu packages on my Linux Mint 7 system from Jaunty to Karmic. Please help as I do not want to re-install. I am running Knoppix 6.3 ATM and I should be able to chroot from that if necessary. I am booting from /sda1 that has Linux Mint 8 installed and grub 1.97.
