--- Comment #28 from Justin Stressman <jstressman at gmail.com> --- I'm seeing the same kind of issue here on my 3 monitor setup with Dell u2412m monitors. The 2 DVI connected monitors wake every time, but the Display Port one rarely wakes if the screen has been off for awhile. I have so far been loading display properties and making a change to that monitor (like rotating it) and hitting apply, which wakes it, and then just reverting the changes. Powering off and back on again didn't seem to help if I recall correctly. I'll have to try again the next time I run into the issue. video card: [AMD/ATI] Tahiti XT [Radeon HD 7970/R9 280X] Software: - xorg-server 1.14.3 - mesa 9.2.1 - xf86-video-ati 7.2.0 - glamor 0.5.1 - libdrm 2.4.0 (?) -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
