I just pulled and am using 68a5ad4. mplayer -vo gl or gl2 works but uses sw rendering and is very slow. Incidentally, apropos the backlight commit in xf86-video-intel, it seems like the driver always sets the backlight to 0. Whenver I start X, backlight goes to minimum. I can crank it up with Fn+Home, but if I restart X then it goes back down again. /proc/acpi/ibm/brightness is always accurate, showing 0 after X starts. > However, we have we replaced it with a worse bug...

Maybe a quick DDC query could be done first, and if that seems to indicate that something is connected only then do the heavy work reading the border color? > https://bugs.freedesktop.org/show_bug.cgi?id=29536 Lovely! The patch works well for me, booting with drm_kms_helper.poll=0 on the kernel command line, and I'm back in X now. I need to sort out some keyboard issues, but they are unrelated. The commit message mentions runtime switching of the polling - how is that done? As I understand it I might have to do that in order to run xrandr e.g. to set up a projector, or possibly after - or no? > > I've just upgraded my userspace and have xorg-server-1.8.2.

Disabling polling made no difference for Xv.

The cursor I mentioned is the VT blinking one. > very pessimistic guess for the memory fetch Aha. Thanks for the explanation! //Peter _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
