Hello ALUG,
I have an odd graphics problem on my Debian laptop: I'm getting strange flickery pixels:
http://www.richard-lewis.me.uk/flickery-pixels-20080220.jpg
I don't get it with the kernel framebuffer but I do get it with X whatever window manager/desktop environment I use. I've tried restarting X, re-installing some X packages and even restarting the computer.
One thing I haven't tried which someone suggested was a live CD using a different XOrg version.
Any other suggestions or similar experiences?
Cheers, Richard

What graphics chipset? Which driver version? Has it only recently started or always occurred? Do you have subpixel rendering enabled perhaps? What does Xorg.0.log say?

What graphics chipset?
(II) intel: Driver for Intel Integrated Graphics Chipsets: i810, i810-dc100, i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G, E7221 (i915), 915GM, 945G, 945GM, 945GME, 965G, G35, 965Q, 946GZ, 965GM, 965GME/GLE, G33, Q35, Q33, Intel Integrated Graphics Device (II) Primary Device is: PCI 00:02:0 (--) Chipset 852GM/855GM found
Which driver version?
(II) LoadModule: "i810" (II) Loading /usr/lib/xorg/modules/drivers//i810_drv.so (II) Module i810: vendor="X.Org Foundation" compiled for 1.4.0.90, module version = 2.2.0 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 2.0
Has it only recently started or always occurred?
Just recently.
Do you have subpixel rendering enabled perhaps?
I don't think so. I found "XAANoOffscreenPixmaps" enabled in my "Device" section. (I think I may have added this ages ago when I tried compiz.) I tried disabling it but it didn't make any difference.
What does Xorg.0.log say?
I can't see any obviously related errors or warnings.
I tried an Ubuntu live CD earlier on and the graphics seemed fine with that so I'm hoping it's just an X problem. Maybe I could try installing a different version of X. Or different video drivers?
Thanks for your help.
Cheers, Richard

OK, following further helpful advice, I've downgraded (pinned) some of the X packages:
xserver-xorg (1:7.2-5) xserver-xorg-core (2:1.3.0.0.dfsg-12) xserver-xorg-video-i810 (2:2.1.0-2)
and it seems to be working again now.
Thanks for the help.
Cheers, Richard
