Ubuntu Installation :: White Screen Instead Of Desktop In 10.10 (Radeon 7500 Card)

Oct 3, 2010

I have upgraded an IBM T41 laptop from UNR 10.04 to 10.10 beta. Upgrade ran fine.

After rebooting, I see the splash screen, and eventually the screen goes white. It does this over a few transitions, most likely in the time between X starting and having the desktop loading (I have auto logon enabled).

Once it is all white, I can Ctrl-Alt-F1 to the terminal. Since then I have disabled auto login but same result. I have also removed Unity (I use UNR and the T41 doesn't have a 3d graphics card), and have the same white screen.

Only after removing xserver-xorg-video-radeon, can I get to the Ubuntu Desktop (in 16 colour glory).

The Thinkpad T41 has a Radeon Mobility 7500 in it, and ran fine in UNR 10.04 (which is also a different kernel).

There was no xorg.conf in use (although I have added one during testing and forced the radeon driver to load) and I reviewed xorg log but didn't see anything.

Debian :: Which Driver For Mobility Radeon 7500?

Jan 31, 2011

I'd installed Puppy and was very happy with the performance on my laptop, but I decided to switch to Debian because of the ap-get feature. I decided to go with JWM instead of one of the default desktop environments, but now I'm having to configure everything manually, and I'm pretty lost. So far, I've got X and JWM installed (though no graphical login, and have to startx manually).

Priority one is to update the video driver and get the best performance possible. I have an ATI Mobility Radeon 7500. I know the fglrx driver doesn't work with this card, but I don't know which package to install. When I type "apt-get install radeon", it spits out "E: Couldn't find package radeon"

Hardware :: Radeon 7500 - Xorg Bogging Down Cpu - KDE Sluggish

Feb 16, 2010

I have installed Debian 5.0.4 (lenny, kernel version 2.6.26-2-686) on an old Dell desktop box and can't seem to make the graphics card happy. Xorg is using up to 70% cpu causing KDE to be extremely sluggish.

After much googling I initally tried adding these options to the device section in xorg.cong, to no avail.

Option "AccelMethod" "EXA"
Option "MigrationHeuristic" "greedy"

I then discovered DRI was disabled because the Radeon driver was loading before agpgart.

I found this:

Quote:

But there was no modules.conf so I had to create a file in modprobe.d instead and it doesn't allow the use of pre-install so I had to change the syntax but agpgart DOES appear to get loaded now as my initial errors about it not loading before the radeon driver are no longer showing up in the logs.

HOWEVER, Xorg is Still killing my cpu and there is no improvement at all.

Now I get these errors instead.

Here is the output of lspci:

I'm pretty new to linux and don't know where to go from here to troubleshoot this problem. Any advice would be appreciated! Let me know if you need more logs or details.

Ubuntu Installation :: 9.1 - Can't Get To Boot - White Pixels At The Top Most Row Of The Screen

Feb 23, 2010

I recently downloaded Ubuntu 9.1 and burned it to a CD. However, I can't seem to get it to boot. I got to the main menu and selected to run it directly from CD, and the Ubuntu symbol showed up saying it was loading things, but then the screen went black and nothing happened even if I waited over 15 minutes. During this time the HDD light was flashing every second or two, and I could see about three white pixels at the top most row of the screen.

Ubuntu Installation :: Black Screen W/ White Stripes ?

Jun 20, 2010

I 've recently installed UNR 10.04 Lucid Lynx in my old PC.

Specs:
CPU Intel Pentium 4 2.66 GHz
Mother ASRock P4i45GV R5.0
Chipset Intel 845GV w/ Intel Extreme Graphics (shared memory up to 64 / 256 MB -I don't really get which one-).

Nevertheless, when I start the Pc, Ubuntu loads and, when it's about to load the desktop, the screen turns black with white stripes and "turns itself on and off" (like when it receives no image). I don't really know if this is or not a graphic bug / problem, but it's quite strange, as I've used Ubuntu 8.10 and 9.10 before in that same Pc.

By the way, I get the same error with the normal Ubuntu Lucid. AND, I have a Win XP Professional SP2 installed (I've installed the Ubuntu afterwards, so I have the Grub as default bootloader).

Also, I get the same error when loading Ubuntu in LiveCD mode.

Ubuntu Installation :: White Screen On Start Up - Won't Launch

Dec 15, 2010

I have been running Ubuntu 10.04 Lucid not on a separate disc partition but installed right on my Windows (7) partition. Everything was working fine until yesterday. I restarted my computer and then the system was scanning the disc then suddenly after the disc check, the computer restarted and when it was supposed to launch Ubuntu, the screen went completely white. I tried restarting again, I manage to get to where I choose to boot with Windows 7 or Ubuntu. I choose Ubuntu and the same happens again: white screen. It doesn't go any further than this and the only thing the computer can do is boot with Windows 7. Has anyone had the same problem? Also, is there a way I can access my files (saved in Ubunutu) from Windows? If I can manage to copy these files then I don't mind reformatting the whole disc.

CPU-Pentium 4
RAM-1GB
HDD-60GB (yeah i know, it's old)

Now if I go into recovery mode and choose any of the options [normal boot/failsafe-graphics boot] the screen goes completely white. I spent hours searching Google for a solution but nothing worked. what is the problem and also what will be the solution for it.

Loads to the screen where you choose between regular and recovery, select e for the normal boot to see boot commands.

The GNU GRUB 1.98 boot reads as follows:

What do? ubuntu 8 worked fine, i ran an update to 10 and it did the same thing. i figured i would try debian since i have it on my other 2 computers. this is being installed on a desktop with a radeon 9800 graphics card. i know the card is the problem because of a driver issue (as i've read) but how do i get it.

Fedora Installation :: White Screen On Boot Of F 10

Jan 7, 2009

I have a Gigabyte GA-MA790FX-DS5 with an AMD Athlon 64 X2 and 4GB RAM. The MoBo does not have embedded video. My main video card is a Diamond Radeon HD3650 PCIe. I was unable to initially install F 10 as the screen would blank out (Black Screen) after it would start Anaconda. I attempted to boot using the suggested option of nomodeset with no change of symptoms. I then switched out to an older PCI video card (NVIDIA GeForce FX5200) and was able to go through the install. Now I am attempting to switch back to my preferred card (HD3650) and just before the GDM screen appears the screen goes to solid white and no ability to switch to another VT. I have been unsuccessful at finding any workarounds for this. I thought the issues were with the older proprietary chipsets pre open source of ATI which was supposedly older than the R500 series, but I guess I'm wrong.

complete trying newbie trying to get to grips with linux. Tried ubuntu and didnt like that so someone suggested fedora. I'm having the same problem I had with ubuntu, I get a white screen when trying to load the graphical install after the media test. On ubuntu this was solved by selecting simple graphics mode.

The text install just freezes after selecting the keyboard layout so that does not even work. Tried searching for forums but only solutions I could find where the previous.

Ubuntu Installation :: 8.04 Vs 9.10 - ATI Radeon 9000 Graphics Card Doesn't Recognize

Jan 20, 2010

I have an ATI Radeon 9000 Graphics card that Ubuntu 9.10 doesn't seem to recognize no matter what I do. Knowing that its an older card and that ATI stopped support for it a while ago, I was wondering if anyone knows if I would have better luck on Ubuntu 8.04. I can't get 3d or opengl to work, or install the correct ATI Driver.

Ubuntu Installation :: PC Resets After 10.04 - Blank Screen With White Text

Jun 11, 2010

So everything went fine in my installation of ubuntu 10.04 but when the pc was reset after installation, it goes to the black screen with the white writing and then does nothing. To check if there was a problem with the disk I had burnt, I installed an an older version of ubuntu (8.something) which had previously worked and the same thing happened: installation goes fine but then when I reset it goes to the black screen with white writing and does nothing. I then tried to install 10.04 again through usb with the same results. Do I need to change a BIOS setting?

Ubuntu Installation :: White Screen Fades Out During Boot (not WSOD)?

Feb 27, 2011

10.10, and I am havingn interesting issue.During boot, right after POST and right before the bootloader screen with the progress bar and Ubuntu logo, my monitor goes completely white. However, almost instantaneously it starts to fade to black, and eventually goes away. I know it's not the white screen of death that I've heard about, because next I can log in and use my computer just fine.If anyone could point me in the right direction to try to fix this, I would greatly appreciate it. Even filenames related to Ubuntu boot would help, as I'm still learning.

Fedora Installation :: The Video Card Is An ATI Radeon And The Drivers From The ATI Site Don't Work

Aug 10, 2009

I've loaded Fedora and must say what a nice OS! But I'm having some issues getting the video working correctly so let me jump right into the issue. The video is very garbled and hard to read. can't seem to find a way to correct what would appear to be a driver issue. Here are a list of things tried:

- display works fine with Ubuntu

- display is clear but is chopped off when using an external monitor from onboard vga slot

The video card is an ATI radeon and the linux drivers from the ATI site don't work with the new images that are out yet.

Ubuntu Installation :: White Screen After Installing Nvidia Restricted Driver As Prompted

Jan 6, 2010

I've had Ubuntu installed on my desktop for a month now, and its all worked like a charm, so I'm thrilled. I then decided to install it on my old laptop as well to see if I could breath a bit more life into it, and to get used to working Ubuntu a bit more. The laptop had 18.6GB partitioned to C:// drive or windows XP, and an empty 18.6GB D:// drive, so I deleted the D:// drive in XP using the Microsoft disk utilities tool, all well and good. I then did a clean install of Ubuntu-9.10-desktop with an Ubuntu CD into the largest continuous free space, and it set it up nicely. When I first booted it up there were a ton of updates to install, as there had been on the desktop first time, which I dutifully installed. As on the desktop a little notice popped up telling me to install the NVidia Proprietary driver for the NVidia card (specifically "NVIDIA accelerated graphics driver (version 96)[Recommended]"), as it had when I installed it on the desktop, so I chose to install that and then restarted the computer.

On restarting GRUB2 loaded, and it booted Ubuntu. I then saw the little white logo on the black screen for a couple of seconds, and then the screen goes completely white, with some pixels left behind fading to white slightly slower. First time through I held down the power button to force shut down, and on restart exactly the same thing happened. This time I held down alt+sysrq and went through the R, E, I, S, U, B sequence, however as opposed to usual I didn't get a black terminal-like screen after hitting any of the buttons, although it did reboot on B. It did boot correctly in recovery mode, however I was at a loss what to do here. Incidentally, the same problem occurred when I booted to previous version of the kernel as well.

Then I decided that as I didn't have any data to lose, and it was still early in the day, I'd do a clean re-install. This time I chose to ignore the updates, and just install the NVidia driver as prompted to check that it was the driver causing the trouble. Having installed the driver and restarted I got exactly the same problem as before - definitely this pesky NVidia driver, not any of the updates.So here I am at clean install 3, having just got all the updates, but not having downloaded the NVidia driver as prompted, with little desire to go through yet more reinstalls. My questions are:

1) Do I need to install this NVidia driver? The rest of the computer specifications are fairly paltry by modern standards, and I won't be doing anything graphics intensive on it (the most graphical program will probably be Battle for Wesnoth) and I I don't need to install it, not installing it seems to be the easiest way to solve the problem.

2) If I do need to install it how would I go around doing this without getting my charming white screen?

3) Is there a way of removing the driver from recovery mode that doesn't involve a clean install again? I have tried sudo apt-get purge nvidia-driver, which tells me there isn't any installed. I have tried sudo rm /etc/X11/xorg.conf which made no difference. I have tried dpkg-reconfigure xserver-xorg and this didn't help. I have tried a couple of other commands as well but I can't remember them, however I would probably recognise them if I saw them again.

Onto System information - pulled from listed specifications and SysInfo:

General System Information
Release:Ubuntu 9.10 (karmic)
GNOME: 2.28.1 (Ubuntu 2009-11-03)

[code]....
