http://bugzilla.suse.com/show_bug.cgi?id=899501 Bug ID: 899501 Summary: Only one display wakes up after powersave Classification: openSUSE Product: openSUSE Factory Version: 201409* Hardware: x86-64 OS: Other Status: NEW Severity: Major Priority: P5 - None Component: X.Org Assignee: bnc-team-xorg-bugs@forge.provo.novell.com Reporter: lmb@suse.com QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- Created attachment 608781 --> http://bugzilla.suse.com/attachment.cgi?id=608781&action=edit Xorg.0.log I have a Lenovo Thinkpad T440s with Intel graphics. I'm using a dual monitor setup - the internal 1920x1080 display on eDP1 and a 1920x1200 screen (HP ZR24w on DP4 via the docking station). (Running Factory as of now, but tried 13.2b1 yesterday and had the same effect.) Leaving the system alone for a bit leads to the screens being turned off (powersave). However, only the internal display wakes up again; the external output remains in power-save mode. (e.g., the monitor doesn't find any signal on any port.) I tried using xrandr --output --off and turning it on with --auto again, turning off the monitor itself, etc. No change; the only apparent way to resolve this and get my external monitor back is to reboot, which seems a bit harsh. Any suggestions? 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) Screen 0: minimum 8 x 8, current 1920 x 1200, maximum 32767 x 32767 eDP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 175mm 1920x1080 60.01*+ 1400x1050 59.98 1280x1024 60.02 1280x960 60.00 1024x768 60.00 800x600 60.32 56.25 640x480 59.94 DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis) DP4 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 546mm x 352mm 1920x1200 59.95*+ 1920x1080 59.99 1600x1200 60.00 1680x1050 59.95 1280x1024 60.02 1440x900 59.89 1280x960 60.00 1024x768 60.00 800x600 60.32 640x480 60.00 DP5 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) Pl -- You are receiving this mail because: You are on the CC list for the bug.
