Description Andrej Podzimek 2005-11-23 04:54:05 UTC
Most recent kernel where this bug did not occur: 2.6.13.1
Distribution: Using Vanilla kernel, not stack. (ArchLinux)
Hardware Environment: Asus M2400N, Centrino, Intel 855GM
Software Environment: Linux/X.org/KDE

Problem Description:
GLX seems to be buggy. glxgears work flawlessly. glxinfo says direct rendering
is on. However, OpenGL screensavers and apps either fail immediately, or produce
a strange output, using only the upper part of the screen. Some of them
segmentation faulted soon afterwards.

Xinerama does not work any more. The double-headed layout cannot be used any
more. An attempt to load X with double-headed layout results in blocking the
chipset and the machine has to be rebooted to make X work again.

Steps to reproduce:
Launch X with KDE or Gnome and try some GL screensavers like Euphoria. Try
startx with a double-headed layout or Xinerama turned on.

Exactly the same problem in 2.6.14.3.
Comment 2 Dave Airlie 2006-01-19 02:30:36 UTC
you didn't upgrade X.org by any chance at some point, or does going back to
2.6.13.1 work with your current X setup? do you get direct rendering with 2.6.13.1?

Please reopen this bug if:
- it is still present in kernel 2.6.16 and
- you can provide the requested information.
