Public bug reported:

Binary package hint: xserver-xorg-video-intel

System: ubuntu jaunty 64bit
Hardware: Notebook Samsung Q35. Intel GMA 950 video card.

$ lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Before my upgrade to ubuntu jaunty there were no issues in regard to the graphics card.
After the upgrade to jaunty, my X11 server crashes every 1 to 2 days. It's a real pain.

First the symptom was that the system looked like it freezes up (screen
visible; sometimes the mouse pinter was movable; sometimes not or
invisible). No keyboard keys and button had an effect (except for the
backlight button). But the kernel still was alive (i.e. the music played
a bit longer - until the program terminated due to the crash crash of
"whatever"). That's why I concluded it's not a kernel but an Xorg issue.

In an article about bad support of the intel chips i read about the hint to disable DRI.
After disabling DRI, the behavior  slightly changed: in the 1 to 2 days crashes, I'm now logged out and the gdm login manager reappears.

Xorg.0.log does not show anything. Likewise
/var/log/{messages,syslog,..}

Because it really goes to my nerves I write this report today.

Btw, I have the gnome desktop. Since my upgrade to jaunty some kde
applications have black bars in some text fields (i.E. when writing or
moving the cursor in kmail's "To:" field, the text becomes black).

There's no special application triggering the problem. Mostly I was
typing in a gnome-terminal via ssh to a remote host. But sometimes i
scrolled down in my webbrowser, or wrote in gvim - or was thinking and
just pressed the shift button.

I've not enabled desktop effekts.

Attached below: Xorg.0.log.old
