Ubuntu Installation :: Get Stuck At Black Flickering Login Screen?
Mar 10, 2010
so i have been trying to install ubuntu for quite some time now and i have run into a bit of a roadblock.
I have tried to install 9.10 and it installs just fine (the GUI works just fine and everything seemingly goes ok), however when i go to boot it, i get to a flickering screen asking for my username and password (this is not the gnome login screen, it is just a blank black prompt asking for me to login). however, the flickering is inhibiting me from easily entering anything in from my keyboard. Thus, i cannot log in to fix the problem (i cannot enter my password because i dont know if the keys i am entering are being accepted or not). and recovery mode does the same thing.
This happens if i try installing it straight up, or if i install it inside windows. I have tried all kinds of boot options and install options (all that acpi crap) but none of it works.
i even tried installing some of my old copies of ubuntu (8.04), but when i do that the grub cannot load the linux kernel. I have also tried both the 64-bit and the 32-bit versions to no avail.
I am running an ASUS motherboard, AMD quad core x64, dual Nvidia geforce 8600's, 6 gigs of ram, and PLENTY of hard disk space.
I am not a noob to linux at all, but i have never encountered a problem like this and i have no clue how to fix it. Hell, i dont even know how to go about fixing it without logging in.
I've put a new hdd into my old comp to try it out, I am using a usb to try and install. When I install I get writing scrolling down the screen then it flicks to a black screen and just stays there. Am i doing it wrong?
I've just installed a fresh Ubuntu 9.10 (I'm using Windows 7), after completing the installation, may laptop rebooted but following the white icon of Ubuntu were the 2 lines "Ubuntu 9.10 computername tty1 ...etc" appears and I could not login due to flickering.
Yesterday I upgraded from 9.10 to 10.04 via Update Manager. But when the upgrade procedure was finished and I made a reboot, I only come to the Ubuntu logo appears for a second, then the screen turns completely black and nothing happens. I then have to reboot via the power button.
But I can get it working with so far no problem, by booting to the third option in the boot options list. In the list there are several options, something like this code...
Now the question is; what does this mean when there are several alternatives with the same name? What is the difference between alternative 1 and 3, other than 3 is working and 1 is not? Is there any problem running alternative 3 instead of 1, and if so how do I get it to boot from alternative 3 as standard?
If this is not the right way to do it, how can I figure out what the error is on alternative 1?
i always had problem with my ATI card and Gnome GUI i decided to install Debian without any GUI at all. After login in CLI i used those commands:"apt-get update""apt-get install alsa-base xorg kdm kde gtl-qt-engine" .I decided to manually install KDE because i had no problem with it in Open SUSE. After that I restarted my pc and got flickering login screen, I'm unable to swith to console becasue after hitting ctrl-alt-F1 I'm getting black screen. I searched google but with no luck, and if there was some solution it required you to be logged in into GUI.
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.
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.
I am trying to install ubuntu on my dekstop computer, i put in the cd it boots, i choose language, and when i get the menu where i can start ubuntu from cd, install it etc. Whatever option i press enter at, i am stuck at a black screen with a flashing white _ in left top corner.I am using an external usb dvd drive.i tried the same usb dvd drive at my laptop and the white _ was there for just some seconds and then ubuntu started doing what it should.
I tried to install Ubuntu 9.10 on one of them by default installation. For the moment there is only one user declared. The installation seems OK, except that Ubuntu didn't find my PPPoE connexion. When I logged in, I got a blank screen with the mouse cursor (it moved, but when I left or right-clicked nothing happened) and on the left something looking like two 1-pixel wide menus, as if the system had understood there were a dual screen. These menus could roll and unroll, and I think I even once managed to shutdown by going to the last invisible item thanks to the keyboard arrows (I'm not sure, because I had also clicked on ctrl+alt+suppr, so it could be a delayed effect of that).
I restarted the computer several times, to get no more than that. When I'm in Gnome safe, everything is OK but I don't have any root privilege there (I guess it's normal): for instance, I can't set up the internet connexion. My 20" 4/3 Philips screen is recognized. Then I changed the screen frequency: it's still OK for Gnome safe session, but now, in the Gnome normal session, instead of a black screen with 1-pixel wide menu, I get a black background picture with white light coming from above and reflecting to an otherwise invisible floor. The mouse cursor is moving, but this is the only thing which works.
I just Installed Ubuntu on my PC (win XP-pro) using wubi, by downloading the .iso from webpage and burned it to cd. The installation went fine, but when I login the screen goes black. I can still see my mouse pointer and one vertical pixel line of the desktop. Could it be the graphics drivers, if so how can I update/change them, via rebooting in safe mode and using command line?
I just used a LiveCD to install Ubuntu 11.04 x64 on my HP desktop. I'm not sure what you need to troubleshoot. It has the following specs:
HP Pavilion Media Center m8539f PC AMD Phenom X4 9550 QC Processor 5gb ram, 750 gb hdd Came with vista home prem, nothing left of that except the old restore partition, which I have left intact. It had Windows XP installed recently, but that's completely erased. GeForce 9300GE Video Card
Anyway, I want the x64 so that I can have access to my RAM, among other things.
After installation with the LiveCD, it will come on, present me with generic/safe/etc boot options, and then when either safe or generic is chosen, it goes to an (active?) cursor for a few seconds before revving the HD, screen going black, and then... nothing. No indication it is even still powered at all except the light on front.
My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.
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'm trying to install the latest version of Ubuntu Studio. I tried it a few months ago with my HP... a live system worked fine, but when I installed it, it would go blank after the splash screen. I assumed it was some sort of incompatible graphics driver and gave up since I don't know enough about Ubuntu yet.Now I have a spare Dell XPS desktop sitting around and I got the latest version of Ubuntu Studio and tried it again. The install goes by erfectly, this time the welcome screen actually comes up and I can see my username. As soon as I hit enter, which I imagine should bring up the password prompt, the entire screen goes black and won't respond to anything.
I have an problem with login in to a fresh installed Ubuntu with the nvidia drivers (graphics card nvidia 210). So far I have installed Ubuntu 10.04, Ubuntu 10.10 and Unbuntu 11.04, they all seem to have the same problem. when I log in the screen goes black and the pc's hangs. I can switch to a terminal before I login and everything seems operational. I can login to Ubuntu with a fail save x session.
I have just recently installed Linux Lime along with windows 7 Home Premium. Before, there would be a menu asking me which operating system I would like to use. When I click linux it goes to linux and windows 7 goes to windows 7. Now when I click Linux, the black screen you get at the beginning shows a - (dash) constantly flashing on a black screen and won't boot to linux. This is normal as it does that for a second then boots. Now its stuck on that flashing dash on a black screen and won't boot.
I don't know if this has been asked already, but I cant seem to find it anywhere. I have a gateway, p 7915u with an nvidia 260gtx graphics card. im trying to install ubuntu 9.10 64-bit on it but the screen keeps flickering before I can even install it or try without change.
I had 10.10 installed and decided to chance it by upgrading to the Alpha release 11.04.Graphic card is ATI Sapphire X1550 I think (512MB).Apart from trying to get used to the buggy interface (to be expected from the alpha), the screen keeps blinking, goes black for a second every 30 seconds.
I just bought this desktop from my friend and it runs win 7 and ubuntu 10.04. it worked very well the first two days until I changed the hostname of the system.
I did like: hostname myNewName
And everything worked fine. The problem now is when I start ubuntu and and reach username and password screen , I enter my password to login the screen becomes black and return me again to the screen where I put my password again. If I entered wrong password , the system message stating wrong password. On the other hand, when I try to run ubuntu from live-cd I can login easily and access my account.
My friend told me he removed Naultius package and reinstall it for some reason before he gave it to me. Note windows 7 is working properly.
When attempting to boot into Ubuntu 10.04, the screen constantly flickers. It'll stay off for about 2-3 seconds, then come back on for <1 second. This constantly occurs. When reaching the main screen (I think), I attempt to move into a TTY terminal, but the flicker continues. I have attempted to reset the X Server, stop the X server, etc., issue remains. The monitor does not turn off during this flickering. I am able to type, obviously.
Here are my system specs: AMD Athlon 64 X2 Dual (6000+) 2.00 GB RAM ATI Radeon HD2600 XT (x2, Crossfire) HP w2207h 22" Monitor, connected via HDMI
I also have VGA inputs on the back of the monitor and can attempt to switch the input, but that requires me to dig through a box looking for a cable, so I figured I'd post this issue first.
I've tried searching the forums, but that didn't help. Pretty much what happened was I installed ubuntu 10.04 32bit version, rebooted my computer, try to login, and I am not able to since I can not even use my mouse or keyboard, it's stuck.Then, I reboot, and it gets stuck at not even loading to the login screen.Could someone have a solution to this?My system specs:
AMD Phenom II x4 955 GA-770TA-UD3 ATI Radeon HD 5750
I'm using ubuntu 10.04 and I recently tried installing certain python libraries. The installation of pyXML failed because python.h wasn't present. I thought I could solve this problem by reinstalling python. So I did:
Code: sudo apt-get remove python Unexpectedly, this command caused all kinds of other things to be uninstalled (like gnome)
I've been trying to install Fedora 10 but the screen flickers about once every two seconds (not at set intervals though sometimes 5 seconds sometimes < 1 second).I've been searching around and all posts I've read about hh ave pointed to an nVidia driver bug which would make sense since I have an nVidia card but these were all posted back in summer of '08 so I'm not sure if it is still lingering.
My OpenSUSE 11.2 is working fine as samba server, no problems, but I have a problem with KDM.My default init runlevel is set to 5 and every time I try to login at KDM (KDE4), the monitor goes black and returns to the login screen.If I hit Ctrl+Alt+F1 to go to console and start /usr/sbin/console-kit-daemon manually, press Ctrl+Alt+F7 to return to KDM login, everything is fine.What do I have to do to fix this issue?
I been having this problem with the login screen after i enabled it. It shows a little window with the the ubuntu logo with my computer's name underneath with the login button. Clicking the button does nothing but when I hit enter it seems like its booting up but freezes after it says "checking battery [done]" or something like that. is it a problem with the login screen? If so how do I fix it? If not what is the problem?
Alright guys. I need to find a way to enable a black screen screensaver (or turn off the monitor, or something to avoid burn in) while the machine is sitting at the login screen and completely turn off the ability for the computer to sleep. how I can accomplish that?
The wubi installer copied files successfully and asked for reboot. After booting into Xubuntu the flashing logo appeared for a minute. And then the screen looked as if it was trying to show something but could not and flickered and then became dark this continued till half an hour and then I pressed Alt+Ctrl+Del.I tried all the modes but to no avail, only the last mode with command line was working. But it was not helpful for me becoz I dont know most of the commands.When I tried "Verbose Mode" as directed by the WubiGuide - Ubuntu Wiki, CTRL+ALT+F2 did not work when the installer stopped.The computer I use is assembled with Intel pentium 4, VIA chipset and Mercury(Kobian) motherboard.
I made a little change this morning on my karmic laptop, and now after it boots up and I enter my username/psswd, it remains perpetually stuck on the loading page that usually shows only for a couple of seconds. I never actually get to my desktop.
This morning, I thought I would try adding another panel to my Desktop, but I thought that if I added it with the position 'top', it would automatically pop underneath my default top panel. So I would have two panels one under the other, like you often do in firefox. I also immediately set my new panel on 'auto-hide'. Right after, the new panel showed up ABOVE my default panel (like z-axis, covering my default panel) and my screen was absolutely frozen. All my desktop icons disappeared and mouse clicks and keyboard strokes would do nothing.
I was forced to hit ctrl+alt+f3 and do a reboot. Ever since, I have been stuck in this mode. Perhaps if I could access the config file for desktop panels (if there is one), then I could try and revert my changes.
