This is with X.Org X Server 1.7.7 and
(II) LoadModule: "nouveau"
(II) Loading /usr/lib/xorg/modules/drivers/nouveau_drv.so
(II) Module nouveau: vendor="X.Org Foundation"
compiled for 1.7.7, module version = 0.0.16
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 6.0
The nouveau X module is from the lastest git repo (yesterday)
Same configuration as before...
Any Idea ?
Thanx
