'xrandr --verbose' output from nouveau 3.12
I forgot to note, that IIRC the last stable version is my nouveau 3.12 git kernel which I keep around to keep my work system going. With http://cgit.freedesktop.org/~darktama/nouveau/commit/?id=a68e95365a4248d3f58c8663e4513c79273ac704 (disp/nv50: fix dpms regression on certain boards) applied on top of http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-next my DVI-connected monitor (via ThinkPad dock) enables after resume. *** This bug has been marked as a duplicate of bug 82527 *** |
