Description VF 2012-05-27 12:25:53 UTC
Dell Laptop Latitude D800 A13 BIOS
Pentium M 1,4 GHz (non pae)
nvidia GeForce4 Ti4200Go latest video bios from Dell (, A06)
1680*1050 LCD (resolution not listed in grub's vbeinfo output)
Because of high crashes rate (and poor skills), I post this now from windows, then I'll go back to linux to post dmesg and xorg.0.log

Comment 5 VF 2012-05-27 23:14:46 UTC
I see a message on the boot screen:
nouveau : Unknown LVDS configuration bits, please report
Comment 6 VF 2012-05-28 00:57:53 UTC
Here a copy/paste of the 2 strange lines (+1 before/after) in xorg.0.log:
Unknown vendor-specific block f

Comment 7 VF 2012-05-28 01:01:08 UTC
PS: the crashes not only happen in firefox: it seems any "Open file" (or Ctrl+O) dialog crash the xserver (seen in gedit too)
Maybe a concurrent operations display dialog + browse file system?
Comment 8 VF 2012-05-28 01:19:46 UTC
here is a snapshot of the "ugly" screen with nouveau, before I install xorg-edges
I could not install edges's kernel (non pae system), instead I installed the precise ppa kernel 3.4 released 6 days ago
Comment 9 VF 2012-05-28 01:23:55 UTC
When xserver crashes, I sometimes get a popup on restart after killing it stating:
"The system is running in low-graphics mode: Your screen, graphic card, and input device settings could not be detected correctly. You need to configure these yourself."
Then, no mouse keybord available I need to power down to reboot.
Comment 10 VF 2012-05-28 01:30:42 UTC
PS: the snapshot shows gnome3 (gnome-session-fallback because I don't like the Unity desktop); On the picture, you cannot see the "double/echo" cursor, although it is really here

The 2 successive lines are at 26.296 in Xorg.0.log
The brackets enclosed numbers are show in gedit in a square matrix this way:

Comment 13 Maarten Maathuis 2012-05-28 01:58:20 UTC
Do you have the nouveau mesa/dri/opengl driver installed?

If so, it would be nice to rule that out as the problem.

Hi Martin
Thank you for your reply
I find this:
sudo dpkg -s mesa-utils
Package: mesa-utils
Status: install ok installed
Priority: optional
Section: x11
Installed-Size: 132
Maintainer: Ubuntu X-SWAT <ubuntu-x@lists.ubuntu.com>
Architecture: i386
Source: mesa-demos
Version: 8.0.1+git20110129+d8f7d6b-0ubuntu2
Replaces: xbase-clients (<< 6.8.2-38)
Depends: libc6 (>= 2.4), libgl1-mesa-glx | libgl1, libx11-6
Description: Miscellaneous Mesa GL utilities
 This package provides several basic GL utilities built by Mesa, including
 glxinfo and glxgears.

I'm not very good english speaking, so please, how could I "rule that"? Adding key words to the bug report?
Comment 15 VF 2012-05-28 02:53:28 UTC
I forgot to say I stick using Gnome classic (no-effects) that's why I posted here in xorg instead of mesa. Should I move the bug?
Thank you
Comment 16 Maarten Maathuis 2012-05-28 04:15:02 UTC
There is an easy way to check (you have to run this from Xorg), that is to run "glxinfo":

This line (or something like it) "OpenGL renderer string: Software Rasterizer" means you don't have the nouveau opengl driver installed, but if it lists something other than software rasterizer you may have it installed.

I'm guessing mesa-utils is not the driver package.

To "rule out a problem" means "to check something is not the problem" in this case.

Can you attach (you'll probably need to copy them somewhere first):


Comment 18 VF 2012-05-28 23:55:17 UTC
Hi Maarteen
Thank you for spending time with me. Hope this is not waste.
Here the line I read from glxinfo > glxinfo.txt:
OpenGL renderer string: Mesa DRI nv28 x86/MMX/SSE2

Would you advise me to uninstall something. If you need to read the full file, please tell me, I'll attach if (xserver hanged just after issueing the command and Ctrl+Alt+PrtScn+K won't revive it)
Comment 19 VF 2012-05-29 00:17:14 UTC
Hi Ben
here are the 2 files; I had to switch to windows to post them, so I also add the glxinfo;

Good night gentlemen
Just a little more comment to add 2 other symtoms. Not sure if they are usefull: clicking the drop-lists is this very page olso hangs the xserver, and about the double cursor in the title, in fact it is not truely a double well drawn clean double cursors, instead it is badly drawn and blury, and if you know the grid (I learnt today it is the name of this thing) that displays over the background picture of the default ubuntu loging screen (the greeting screen is the name I beleive), so each point of the grid is doubled, about 1mm on the right (or left, I can't know), like the phantom/echo on old tv with poor signal before DVB. I'll post a photography of the current cursor just in a few minutes...
Comment 24 VF 2012-05-29 14:03:20 UTC
When I opened the cursor photo, metacity repported an error.
In fact on login, the grid over the flat purple color is not doubled immediately; it turns doubled at the same time the artwork shiny picture overrides the flat purple. Now I switch to win to post the photo, and maybe a small video to show what happens on login.;;
bye bye

Comment 26 VF 2012-05-30 07:41:18 UTC
I posted the bug https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1006437 after ppa-purge because Canonical support asked me to ubuntu-bug xserver-xorg-video-nouveau, and this command said it can't work because of third party packages.
Comment 27 VF 2012-05-30 08:12:15 UTC
Should I now revert back to you xorg-edges guys?
bye bye

Comment 28 Glenn 2012-06-12 16:33:55 UTC

Ubuntu 8.04 supported this card with the nv driver. Nouveau has never, to the best of my knowlege, supported this card. We could really use nouveau support, as I have read that nvidia is considering ending support for this and all nvidia-96 cards. I have the same pointer and desktop graphics corruption in Ubuntu 12.04.
Comment 29 VF 2012-06-12 23:34:24 UTC
Thank you Glenn, I ended feeling I just posted silly noise

Bios recommended update

I got the PC already flashed with this video bios from dell/nvidia
Comment 31 Tesloid 2012-08-01 19:26:33 UTC
I am previewing the next release of Slackware, on a similar D800, and am seeing even worse corruption than your screenshots indicate.

The problem is, the current version of Xorg will no long work with the proprietary nvidia driver (Nvidia has not updated their legacy driver);

The "nv" driver segfaults (I have not been able to figure out why: this is using a configuration that used to be fine).

The nouveau driver is all that will load in 1920x1200 now, and the graphics are too corrupted to be used.

I cannot find a way to get 1920x1200, even unaccelerated, with an nv28 card now.

Hi this bug might be related to the one I've reported here
as asked by debian mantainers.
Comment 33 VF 2012-09-09 19:15:06 UTC
nvdia just released a new driver: see https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-173/+bug/948053 post #119

Marking this as a duplicate of the bug which has more up-to-date information. Description seems identical. Feel free to undup it if I got it wrong.
