Description Tamás Németh 2009-05-06 06:11:10 UTC 
I'm using X.Org server 1.5.2 from the 64 bit openSUSE 11.1 distribution. Environment is KDE 4.2.2 (probably irrelevant), window manager is compiz-fusion with AIGLX. When I change to anothe LInux virtual terminal (Ctrl+Alt+F1 for example) and then back to tty7 with the X server, some pixmaps get garbaged, for example the "cube caps" and window preview border glows (see the attached images). Reloading compiz solves the problem, but it's a bit annoying, since I have to reload it after every suspend/resume cycle.

Here it is. I must also notice that this kind of pixmap garbaging doesn't only happen on virtual terminal switching, but also when I start an application with hardware 3D acceleration (e.g. xmoto, Google Earth)


I observerd another problem. Originally it wasn't reported as an Intel driver issue, but please take a look at it. Isn't it an Intel driver issue in my case:

Some additional info (regarding the drm kernel driver):

I'm using the standard 64 bit openSUSE 11.1 kernel:

milleniumfalcon:~ # uname -r
2.6.27.21-0.1-default

And I'm seeing these messages in dmesg:

milleniumfalcon:~ # dmesg | fgrep i915

In addition when DRI is enabled (thus drm and i915 kernel modules are loaded) then, during X server restart, when a text console appears for a moment (wich is normal), this text console ALWAYS has some colorful visual garbage. This visual garbage is an approximately 1,5 cm wide horizontal stripe of randomly coloured pixels from approximately 2 cm from the top of the screen.

Moreover, when DRI is enabled and compiz uses it via AIGLX, SOMETIMES (mainly during returning from suspend), the X server crashes. After this crash, the X.org server restarts and I can use it, but all the character virtual terminals become unusable: The character VTs are full of narrow blue vertical lines (like a barcode) on a black background, also showing an X mouse pointer. I have to restart the machine in order to be able to use the character virtul terminals.

Please try with kernel 2.6.30 or newer, Mesa 7.5rc or master, server 1.6, and xf86-video-intel 2.7.1 or newer.  You're using EXA and DRI1 and non-GEM, which are a really bad idea for use with compiz.
Comment 8 Eric Anholt 2009-09-25 11:26:57 UTC 
Closing due to feedback timeout.  If you still have the problem with current components, please reopen.

OK, this can be left closed. Finally I was able to install openSUSE 11.2 MI8, and I observed that all these issues are gone. The new Intel driver performs extremely well.

My only problem with thas system is this:
