Running xubuntu 12.10 (xfce 4.10) with nvidia binary driver (304.51). I noticed something similar to this when using the redshift utility. After a suspend, my screen in the morning would retain the gamma correction from the previous night.
Using xrandr manually: ~$ xrandr --query (...) DVI-I-1 connected 1680x1050+1680+0 (normal left inverted right x axis y axis) 474mm x 296mm (...) DVI-D-0 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 433mm x 271mm (...) ~$ xrandr --output DVI-I-1 --gamma 1.0:1.0:1.0 doesn't produce any visible results immediatly, but WILL after you switch to another VT and back to X (say alt-F1 then alt-F7). Using the nvidia-settings utility to set the gamma values shows the same behavior, the settings are only applied after a VT switching. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1015297 Title: Screen partially darkened after suspend and resume in Xubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/pm-utils/+bug/1015297/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
