Bug#987054: xserver-xorg-core: modesetting driver fails asking for OpenGL version 2.1 or later

title xserver-xorg-core: modesetting driver failing requesting OpenGL >= 2.1

Thanks so much Josua!

I was facing the same problem... with a completely different card. An
old NVIDIA GeForce, for which nouveau works for a while to then freezes
with a GPU lockout. Trying to use another driver failed with the same:

> (WW) Require OpenGL version 2.1 or later.
> (EE) modeset(0): Failed to initialize glamor at ScreenInit() time.

So it's not just Vivante GC2000 that suffers this.

The real merit goes to Lubomir for the upstream implementation, of
course, but without this bug, it's unlikely I would have found commit
26004df6.
Plus, your backport worked flawlessly.

Debian X, it would be nice if this could be included in a point
release.
