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
This should be in the 5.2 release notes.
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
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.
adding to RHEl5.2 release notes updates:
(x86_64) On an IBM T61 laptop, Red Hat recommends that you refrain from clicking
the glxgears window (when glxgears is run). Doing so can lock the system.
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].
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.
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"
thanks Jane. added to note for this item in RHEL5.2 release notes updates:
To prevent this from occurring, disable the tiling feature. To do so, add the
following line to the Device section of /etc/X11/xorg.conf:
Option "Tiling" "0"
please advise if any further revisions are required. thanks!
