I tried to include everything I could think of but I was pretty sure I would forget something. > Does setting the environment variable vblank_mode=0 for xbmc work around the > problem? Both ways are successful. I had just compiled a new 2.6.35.9 with KMS_DRIVER_MINOR set to 3 and it works fine that way. Right now I booted from a previously compiled 2.6.39.1, setting the env vblank_mode to 0 and it also works fine. I understand we are disabling the sync extension, are we? Or does the vlank_mode=0 do anything else? I am now checking how well video plays. On 2.6.39.1 with vblank_mode=0 video playback is quite worse than I was used to. There is no tearing, but there is some kind of blockiness in the animation. On 2.6.35.9 with KMS_DRIVER_MINOR=3 video is almost like in not sync enabled kernels although there is still some blockiness, not as noticeable as in the other kernel though (vblank_mode is not set). You'll tell me whether we dig further to find if I can use the sync extension on this card or I shall force the older kms driver minor. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
