Description Cameron Meadors 2008-04-28 19:44:57 UTC

Moving glxgears window around on a T61 hardlock the system.  This is on x86_64
with xorg-x11-drv-ati-6.6.3-3.13.el5.  The glxgears window appears and will run
indefinitely if not poked.  If the window is moved around for a few seconds the
glxgears window gets corrupted, the display turns psycedelic, and the system is
locked.

Comment 1 Cameron Meadors 2008-04-28 19:57:26 UTC

This should be in the 5.2 release notes.

Comment 2 Don Domingo 2008-04-29 23:37:10 UTC

thanks Cameron. any known workarounds for this, other than not to use glxgears?
do we ship/support any other graphical benchmark tools that users can, well, use
instead?

Comment 3 Cameron Meadors 2008-04-30 12:52:14 UTC

No work-around that I know of.  I am not aware of any other benchmark tools for
GL purposes.  We ship a very limited number of packages that use DRI and GL at all.

by the way, i tried running glxgears on my test machine. when i maximize the
glxgears window and minimize it, it restarts X. the "Device => Driver" section
on its xorg.conf says "nv", which i think ships with RHEL (?). 

the video card on the machine is nVidia NV41 [Quadro FX 3450/4000 SDI].

Comment 5 Jane Lv 2008-05-09 09:00:37 UTC

I reproduced this issue on RHEL5.2-RC1 w/ both x86_64 version and i386 version.
 I used a SantaRosa SDV machine w/ Intel Crestline graphics chipset. Moving
glxgears window will make system crash.

I will double check this issue on T61 laptop.

Comment 6 Jane Lv 2008-05-12 08:47:56 UTC

We find a workaround of this issue.  Disabling "Tiling" in xorg.conf will avoid
system hangup.  Add the below line into section "Device",

Option "Tiling" "0"

Comment 7 Don Domingo 2008-05-12 22:03:00 UTC

thanks Jane. added to note for this item in RHEL5.2 release notes updates:
