I had VNC working with accounts that were logged in. Then I went thru the procedure for vnc-itsp-config (step 5 of the how-to-centos5 vnc server wiki) so that I could log in remotely to an account that was not already logged in.
All went well until....I tried to log in and all I get is this X11 window with a X cursor and a black screen.
I have restarted the vncserver service but I suspect it is a x11 issue (just a guess).
I had a perfectly well running CentOS 5 system but with an old crappy monitor. I replaced the monitor by a bigger one, i did a monitor detect to make sure that CentOS would recognize the highest possible resolution. Then changed the display rsolution for the current user.
Now when i login as root just a black screen appears with a white mouse pointer and then nothing. I already deleted all the contents in the home directory /root but no improvement.
When i login as a new user X is starting perfectly.
Anyone have a clue what i need to do or delete to get X working again? I can nuke the whole box and do a reinstall but i'd rather not.
I have followed to the letter the wiki HowTo on setting up VNC and it works (sort of). I get a VNC session (doesn't matter whether I connect locally, over ssh, or using a vnc client), but all I get is the dreaded black screen with an xterm top left. If I then execute 'startkde' from within the xterm I get my normal desktop up. What I am however getting, is a new desktop session. And this happens each time I start a vnc session. I.e. I end up with a LOT of user sessions for my username. (As shown up by a 'users' cmd.) Consequently, each new time I start a vnc session, I get <x> (representing the previous nr of vnc logins) number of xterm windows + 1 appearing. I never get the logged on session.
However I've also noticed my .xsession-errors file filling up. I've googled around enough to get the impression that the reason I'm not getting the logged-on session up in vnc is due to a missing window manager. but haven't hit on the right google combo to fix the issue. I can believe there being a missing window manager due the following related story;About a year ago, I went to switch from KDE to Gnome. Decided I didn't want to and then set out to switch back to KDE. Each time I installed/uninstalled via the GUI "Add/Remove Software". Eventually I got back to KDE and it appeared to work since, so I left well enough alone.t is only now attempting to set up VNC, I have come across all these issues. I firmly believe VNC will work as expected if I can resove the apparent missing window manage issue.xstartup

I am running a dell poweredge 2600 in which i just now did a fresh install of Centos 5.5 KDE. The install went perfectly with no hiccups or errors. I reboot the server and centos dose its normal checking everything and giving a Green"OK" or Red"Error" and everything seems to be fine. I then get to a black screen with a X mouse cursor, i can move the cursor freely and i can turn the Num Lock key on and off and i can do a Ctrl+Alt+F5 and then reboot with a Ctrl+Alt+Del smoothly, but i just cant get the centos to boot up all the way into the GUI.
View 16 Replies View RelatedEverything went fine this morning on the Install. Then the box said there were 121 updates. I click YES to update. After an hr updates had finished, and reboot was necessary. Only a black screen came up. I have 2 lights on my keyboard blinking, no hard drive activity light. Waited several minutes, nothing. So I did a reboot back into my WinXP. Any suggestions?

I have a Acer Aspire D250 the new ones that comes with the win 7 starter kit.
When I try to install or just even try to load from the live CD from Ubuntu 9.10 or Ubuntu 9.10 remix the logo come up and screen goes black. I'm using a 4gig Sanddisk cruzer and I formated to fat32.
Is it an option that I need to change into the bios? do you think I really need to use a external DVD to install it?
I tried to find a solution on google but can't find anything
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.
I'm attempting to install CentOS 5.2 x86_64, on an HP Pavilion/Intel Core Duo.
The DVD boots, anaconda starts, displays blue screen with "Loading usb-storage driver", and then hangs at a blue screen of garbage.
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 want to install a Centos Server. In the installation I choose the Gnome desktop, server, virtualization and server gui. I installed the os but when I reboot Centos doesn't appear :(, there is a black screen and it's not possible to write.

I am using Postfix on CentOS to send mail through a relayhost. The mail sends fine, but on certain clients such as the mail client on the iPhone or Windows Live Mail, the message is received with '(No Sender)' in the sender field. The Apple Mail client on the iMac works just fine.
Here is the PHP code I am using to send the mail code...
Wondering if there is a configuration setting in /etc/postfix/main.cf I can use to fix this problem. I have scoured the help files but have come up empty.
I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.

View 12 Replies View RelatedI am having a problem with my Core i5 system running Centos 5.5. The system will lock up with a black screen on occasion when launching X11 - this could happen at any time, from the install CD the first time it's being installed or trying a live CD, or the 3rd-10th time I launch startx from tty1 or sometimes just switching from tty1 to display0 or display1. When the crash occurs, sometimes the systems fans will all turn on loud, and the reset button becomes non-responsive. Other times the screen is black and it just sits there and I have to hard power off. There's nothing in /var/log/messages.
I tried a fix from an old post for 5.4 adding the option for "DDC" "false" in the xorg.conf file, and this did not help. I also ran all the system updates, no help.
The system is totally stable so long as I don't switch between ttys and X11 or launch new X11s (it's also stable under other OSs and has passed Memtest86+ 4).
Is this an instability with the Core i5 driver? The "Video Card" in the display options is set to "intel - Experimental modesetting driver for Intel Integrated Graphics Chipsets" - the "experimental" part is a little scary. Should I try setting the driver to "i810" as the 5.5 release notes recommends (again there's no onboard "chipset" this is an embedded graphics processor on the i5 CPU).

I'm able to connect to ftp as a virtual user. It was also difficult as nowhere mentioned, that it should be done with SSL. Anyway I found the answer and got connection. But now I can't connect to ftp server as system user. It gives me "530 Permission denied", or if I delete the user from the file denied_users, - "530 Login incorrect".
1. Still I can't understand, how I can log in to FTP server with a system user.Also some other questions regarding this matter:
2. My httpd server Apache has a virtual hosts located in "/home" directory.The scripts create users in "/var/ftp virtual_users". Will it cause any problem if I will change them to "/home"? All I need to do with this is ability to have several virtual hosts in one server with separate access to each of them via FTP. And 1 account with access to all files in "/home".
3. In my ftp client I can see the owner of virtual host "ftp" instead of username.
I'm a newbie to installing LINUX (was an Oracle DBA for many years) and I am having trouble getting the dual head function to work with my Sony Vaio laptop. I just select a generic LCD with the screen resolution that I want, but when I startx, I briefly get the login window (terminal), then everything goes blank and I have to unplus the samsung monitor and reboot to be able to have a screen again. I have tried the fn + f keys and that doesn't help.
Here is the hardware:
Samsung Syncmaster 2343BWX
Sony Vaio VGN-FJ170
Intel Graphics Mobile 915GM/GMS/910 GML Express graphics controller
I would like to use this laptop as:
Audio streaming from internet (so far not working on my local NPR stations)
Hooked up to KVM switch - using the Samsun monitor and an adesso integrated keyboard
Wireless network (that is working - but it took some doing....)
What files and logs I need to post I will do so, but if what I want to do is just not possible or a big hassle, please just let me know, and I will load windows. Although I really wanted one LINUX box in my home office.

I have upgrade Ubuntu 9.10 to 10.4 on my Dell Inspiron Desktop and OKI TV monitor. After reboot the new version I can read the menu.lst on the screen and i select ubuntu 10.4 but after the screen is black permanently and the boot process stop. I have tried with a acer monitor and all is OK, but i would like use the OKI monitor. With the OKI monitor I have not problems with old versions of Ubuntu, neither Ubuntu CD Live, neither Knoppix. I have see that there is not /etc/X11/xorg.conf so I have tried with differents xorg.conf files:
a) with dpkg-reconfigure -phigh xerver-xorg
b) copying xorg.conf from Ubuntu 8.10 Live LoW Graphics mode
c) copying xorg.conf from Knoppix Live
but the result is the same : black screen I have tried also Xorg -configure but it say a warning message: "Server is running" I think that start up script dont read xorg.conf and the boot process is blocked

I have Ubuntu on a DVD and have tried both my DVD drives, AND an external DVD drive and have no luck. I have tried different versions of Ubuntu and get the same problem. So I boot it fine and it gets the the Ubuntu splash screen and I select "Install Ubuntu" it loads for a few seconds then goes to a black screen with a blinking cursor in the top left corner. It sits here forever. I tested on my friends computer with very similar processor and it blinks for about 3 seconds then an Ubuntu splash screen appears with dots under it and it loads and works fine.
So I am 100% positive the DVD is fine and should work for my processor also. I do have Windows 7 currently installed. And I made a 100 GB partition via Windows 7 using Easeus Partition Manager. If it matters, I did test Ubuntu on my computer by installing it from VirtualBox and it worked fine...but I'd rather do a dualboot because I don't like running an OS in another OS and its performance isn't so great when emulating an Operating System...
I've got a problem with my Ubuntu Server 11.04 amd64, I think the problem comes from GRUB 2. Here is my problem : I updated my server and I now have Linux 2.6.38-10-server (in addition to 2.6.38-8) and, when I try to boot on version "10", I think I have a Kernel Panic because the screen keeps black and there is no use of the HDD (I can ear it working with version "8"). I also looked at /boot/grub/grub.cfg and I didn't saw any diference between the lines for v10 and those for v8 (except for "8">"10" of course).
I tried with Recovery Mode too, with this result : Loading Linux 2.6.38-10-server... Loading initial ramdisk...
> No use of the HDD (I don't ear it), and it's "frozen", can't do anyting but reboot it by ACPI (nothing happend when hitting "Num Lock") Another question : can we have no submenus in Grub2?
