Hi,
Thanks for reporting this X gpu lockup bug in Ubuntu maverick.
In my opinion GPU lockups are one of the most frustrating kinds of bugs,
both as a user and a developer. I want take a few moments of your time
to explain the situation with these types of bugs.
For some reason, -intel has been
After some more testing I found out that if I set the
option name=bo_reuse value=0 /
in my .drirc (setted by driconf) Webots does not freeze my system. I
can't see the objects (except for some rendered text) which makes webots
still unusable. Has anyone a idea why
Disable buffer object reuse
P.S. Even with the buffer object reused disabled I get all these
../../intel/intel_bufmgr_gem.c:1158: Error writing data to buffer 581: (0 7680)
Bad address .
../../intel/intel_bufmgr_gem.c:1158: Error writing data to buffer 1450: (0 704)
Bad address .
../../intel/intel_bufmgr_gem.c:1158: Error
I just realized that the bug was set to fix released and was therefore
not public visible any longer.
The fix released was set after I incorrectly thought the problem was
gone (with hardware rendering) but I had accidentally still enabled
software rendering in this console. So I hope it is ok to

Webots still freezes under Maverick, but I also updated the Webots
Version to 6.3.0. So I'm not 100% sure if I should open a new bug. But
the symptoms are exactly the same: as soon as I open a simulation where
one of the robots uses a camera I get a freeze of my system. But I was

Sigh, that's disappointing... I would've hoped for a working solution
which involves software rendering, but no.

Hi,
this seems to be related to your GPU and/or its driver which doesn't
support well the Rendering-To-texture (RTT) OpenGL feature used in the
camera device. Generally
This is getting more and more weird.
After upgrading today (some i32-lib stuff and libc updates) the 32 bit
version of Webots is not longer complaining about wrong ELF classes, but
instead it is *also freezing the system* with the same console output
(do_wait: drmWaitVBlank returned -1, IRQs
Ok, I rebooted my system.
32 Bit version again has the wrong ELF class error.
But the 64 Bit version finally works!
I don't know which of the upgraded packages made this happen, but I
think you can close this quite long bug report now :-)

do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly
and

Status:
Arr, I was testing in a console where I executed
export LIBGL_DRIVERS_PATH=/notapath
before.
Without this enforcement of software rendering the freeze still occurs
:-(
But at least I have a workaround now (and the software rendering is
actually quite fast)

Rejecting the Lucid task; this has an easy work-around (using the

Unfortunately this is not true for my special case, since the 32 bit
versions has other problems.
