[PATCH] Fix max texture levels on nv50 (1.15 KB, patch)

Description Jakub Steiner 2011-10-24 10:20:24 UTC 
The driver claims to only support GL_MAX_TEXTURE_SIZE=4096 when the hardware limit seems to be 8192. The limit is used by GNOME 3 (gnome-session-check-accelerated-helper) as a pre check to being able to run gnome-shell, preventing me from using a 1600x1200 + 2560x1440px monitor setup. If, however, I attach the secondary monitor after the session starts up, the hardware seems to be perfectly capable of running the 3D accelerated environment across both displays with no glitches and artifacts. 

This is on Fedora 16 and the card is recognised as "nVidia Corporation G92 [GeForce 9800 GT] (rev a2)"
