Description Ben Skeggs 2015-10-02 05:45:51 UTC
The codepaths necessary to support Glamor acceleration in xorg-x11-drv-nouveau, as required to support all NVIDIA GPUs beginning from GM10x, have bit-rotted and no longer function correctly.  The result is the X server crashing when attempting to log in from GDM.

Upstream Nouveau no longer supports Glamor acceleration, instead it causes the X server to fall back to the built-in "modesetting" driver, which provides identical functionality.

This bug is to backport those patches from upstream, in order to fix the crashes that occur with the current packages present in 7.2.

Can this fix affect also other chipsets than maxwell?

Comment 4 Ben Skeggs 2015-10-02 22:01:03 UTC
Older chipsets are using EXA by default (we have no EXA implementation for Maxwell, Glamor was deemed a better choice), which does not have the mentioned issues.
