xorg freezes with -nvidia (same with -fglrx)

[Šarūnas Valaškevičius]

Binary package hint: xserver-xorg

1) Ubuntu 9.04
2) xserver-xorg:
  Installed: 1:7.4~5ubuntu18
3)system is 64 bit, 4GB ram

tried both ati radeon AND nvidia video cards with their drivers (flgrx / nvidia) results are the same for:
after some time (at once with ati, a bit later with nvidia) screen is filled with psychedelic colors, no response. only reset works.

with nvidia, however, there was a timespan where all things worked ok, later colors became psychedelic but there was still responce, and after some restart, same result as described above.
it was similar as http://www.nvnews.net/vbulletin/showthread.php?t=93293 , but I checked lspci, and it uses the same:

00:01.0 PCI bridge: Intel Corporation 4 Series Chipset PCI Express Root Port (rev 02)
        Prefetchable memory behind bridge: 00000000d0000000-00000000dfffffff
01:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7600 GS] (rev a1)
        Region 0: Memory at fd000000 (32-bit, non-prefetchable) [size=16M]
        Region 1: Memory at d0000000 (64-bit, prefetchable) [size=256M]
        Region 3: Memory at fc000000 (64-bit, non-prefetchable) [size=16M]

for ati: radeon driver does not work too, only radeonhd,
for nvidia: nv driver works ok

for fglrx I used
http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx 9.4 catalyst, which says it supports (early look) ubuntu 9.04 and 7.4 xorg

I could blame ati for bad driver, but with nvidia card + driver is the same.. :(

[Šarūnas Valaškevičius (rakatan)]

one thing to notice (not sure how much worth)

if using nv or radeonhd drivers, card address (d0000000) is written into /proc/mtrr ,
if using flgrx or nvidia - not. could it be that memory overlaps with other applications?

i.e. this is in <4GB range, and I have 4GB ram..

Hi rakatan,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Hi,,

ok, installed nvidia drivers again, was not hard to reproduce - just waited for ~5minutes, used firefox, and colors where .. bad.

then copied Xorg.0.log

[Bryce Harrington (bryce)]

Okay, since you attached the Xorg.0.log with -nvidia, and since it sounds like you have an adequate workaround for the ATI cards, and since this bug needs to focus on one issue at a time, let's target this bug to the problem with -nvidia.

[Šarūnas Valaškevičius (rakatan)]

Hi,

possibly I defined this problem not clearly engouh :)

the biggest problem that I see are these psychedelic colors, similar as in a link I posted.
with these colors X works for some time, and just later, after undefined time period, possibly after switching to console and back, freezes.

I guess after solving color problems, freezes would dissapear too ? because maybe this is a same bug. e.g. memory corruption or...
and 1st result too see are bad colors, not freeze.

thank you for taking care of it :)

[Šarūnas Valaškevičius (rakatan)]

Hi,

got my ATI back.. now, with new flgrx, the problem is gone.

as for nvidia - it is possible that the card itself is corrupted - I had some problems later even with nv module as described in here http://www.linuxquestions.org/questions/linux-hardware-18/freeze-with-horizontal-lines-while-loading-xorg-726693/

it was just strange to see the same problem with two different cards..

or maybe some driver parts were left ?? like xgl module from different versions ??

Sorry for disturbing and thank you for your interest :)

[Bryce Harrington (bryce)]

I've posted a new version of the -nvidia driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

Get nvidia-graphics-drivers-180 - 185.18.14 here:

[Šarūnas Valaškevičius (rakatan)]

sorry, but just two days ago I gave the nvidia card back to its original owner..

Since the hardware is no longer available for doing troubleshooting with, we'll have to close the bug for now. However please feel free to reopen if you or anyone else has the same HW and can reproduce this issue using the latest development version of Ubuntu and is willing to do some troubleshooting with it.
