Downgrade to Xorg 1.6.3.901 fix my problem...

So 2 solutions:
- nvidia bug with xorg 1.7
- xorg 1.7 bug

How to track down problem?

No problems (or at least for now) here on both i686 and x86_64. But I am using a custom kernel 2.6.30.9 and nvidia 192.42 (with MSI-X ints enabled) with a 7300GT.

Latest packages from repos.

At work with 7500 GT, no problem...

So, it's now sure it's a nvidia bug.

Maybe a casuality or not, but...

Here  FS#16952  user have an crash issue with a 9xxx card, you have a another crash issue with a 9xxx card.
But for me 7xxx (both issues) and you with 7xxx (al least this issue), seems to works fine.
I guess this is an issue with 190.42 and at least 9xxx card...

anecdote: I can remember some older posts from many users with 8xxx/9xxx cards with many problems on nvidia forums, but 7xxx not affected.

Anyway, try to rebuild yourself nvidia, then nvidia-utils packages in the problematic system.

Else you can switch to nouveau driver, until it is fixed again.

Confirmed. I can reproduce this every time (similar to  FS#16952 ) by opening a large image in GIMP and trying to scale it or manipulate the colors.

The crash can in my case be worked around by disabling desktop effects.

I cannot confirm this with a G70. I use KDE 4.3.3 with opengl composite and I rescaled some big pictures in Gimp.
Comment by Gerardo Exequiel Pozzi (djgera) - Monday, 02 November 2009, 14:16 GMT
@Thomas: Your nvidia card chip is?
@Pierre: So G70 is a 7xxx chip, true? (7800 GTX if I am not wrong?)
Comment by Pierre Schmitz (Pierre) - Monday, 02 November 2009, 14:34 GMT
Yes: nVidia Corporation G70 [GeForce 7800 GT]
Comment by Thomas Bächler (brain0) - Monday, 02 November 2009, 14:59 GMT
This is a GTX275:

04:00.0 VGA compatible controller: nVidia Corporation GT200b [GeForce GTX 275] (rev a1)

Look at nvidia page, seems to be a xorg bug...

I don't request closure now, going to post a bug report for xorg-server
