Bug Description

Binary package hint: libgl1-mesa-dri

When trying to start any OpenGL-based program it immediately crashes with the output on stdout:

"brw_misc_state.c:290: emit_depthbuffer: Assertion 'region->tiling != 1' failed."

This is on a Lenovo X61 tablet/notebook with a i965 chipset (GPU: intel GMA X3100). The affected file comes from mesa/drivers/dri/i965/brw_misc_state.c

The package in question is libgl1-mesa-dri 7.8.1-3ubuntu2

Tried it with these programs, which all fail with the same error stated above:
* glxgears
* compiz
* mutter
* unity (as mutter-plugin)

Here's an interesting observation. On 19.7.2010 I pulled updates via synaptic in the hope it would pull in a fix for this that might have happened. But that wasn't the case. Then I pulled the live-cd image of the same day, put it on a usb-stick and did a fresh install from that one. This actually solved the issue and fixed tihs bug. This leads to the assumption, that this might be a package-issue or something similar.

The fresh install wiped my xorg.conf with the default one. Thus deleting the line setting "Tiling" "false", which according to Chris "ROAF" Halse Rogers could be a possible cause for the reported bug to happen. I forgot about that option being there and was probably a left-over from some older tweaking attempt for an older driver-version.

I'm going to mark this as invalid. I was considering making the DDX spit out an warning about the Tiling option, but upstream basically regards all options as debugging tools only and make no guarantees any random option won't break some part of the system.

I don't think this is worth a delta from upstream for.
