If you're having trouble telling, that means it's not :) The error you pasted is quite odd. Was there anything in the log before those messages? If there's no channel associated, that means that it's the background copying between vram and sysmem? Not sure. Note that with maxwell we have yet to add EXA support to xf86-video-nouveau, so you're ending up with GLAMOR (and Ben and I disagree on whether EXA support should be added in the first place). There was also an issue that glamor was hitting with nouveau which appears to have dissipated, either due to a change in nouveau or a change in glamor. So you might consider upgrading to Xorg 1.18.3 (as glamor is part of X). FWIW a few other people have been using GM20x without incident, but this can all be very sensitive to your desktop/etc. Lots of things like to use GL nowadays - I stick to a more classic desktop - no compositor, simple window manager, etc. -ilia _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
