However, now on .39-rc, the KMS'd console is stable, and starting X makes it bad again. It there anything useful I can pull from any logs on the startup of X? Either from the X server, or the kernel. Last time I looked at the drm log from the kernel It was unreadable to a mere mortal, but I hope you guys can point me to what debug knobs to enable to get a good view of the interesting parts (How does one start a minimal X, btw? "xinit" gives me an undecorated xterm with the jitter. Can one start something more minimal?) Currently running today's git xorg-server and xf86-video-dri. -Anders _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
