Interesting. I need to add this is happening using a docking station. I found out that the same xrandr output I get when I connect turned off monitor using dsub and dvi cable. When I remove the laptop from the dock and use dsub to connect to monitor, I see all resolutions: DP2 connected primary 1024x768+1920+0 (normal left inverted right x axis y axis) 509mm x 286mm 1920x1080 60.00 + 1280x1024 75.02 60.02 1152x864 75.00 1024x768 75.08 60.00* 800x600 75.00 60.32 640x480 75.00 60.00 720x400 70.08 It is weird though that I still see DP2 and not VGA1. It is also weird that 1024x768 is selected by default. But after I do: xrandr --output DP2 --off ; xrandr --output DP2 --auto I see: DP2 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 509mm x 286mm 1920x1080 60.00*+ 1280x1024 75.02 60.02 1152x864 75.00 1024x768 75.08 60.00 800x600 75.00 60.32 640x480 75.00 60.00 720x400 70.08 Note that my eDP1 resolution is 1920x1080. Sometimes I also see following:
HDMI2 disconnected (normal left inverted right x axis y axis)
1920x1080 (0x50) 148.500MHz
h: width 1920 start 2008 end 2052 total 2200 skew 0 clock 67.50KHz
v: height 1080 start 1084 end 1089 total 1125 clock 60.00Hz
Note that HDMI2 was never connected to anything.
It works again when downgrading to kernel-3.14.8-200. Seems to be a duplicate of Bug 1117008. *** This bug has been marked as a duplicate of bug 1117008 *** |
Created attachment 917481 [details] Xorg log Description of problem: I installed F20, updated. Connected my monitor (actually I tried 2 different ones) via DP. xrandr shows max resolution 1024x720. Sometimes it helps if I turn the monitor off and on couple of times and then the correct resolution appears. Version-Release number of selected component (if applicable): kernel-3.15.3-200.fc20.x86_64 xorg-x11-drv-intel-2.21.15-7.fc20.x86_64 xorg-x11-server-Xorg-1.14.4-11.fc20.x86_64 xorg-x11-drv-modesetting-0.8.0-2.fc20.x86_64 How reproducible: 95% Steps to Reproduce: 1. Connect monitor with resolution higher than 1024x768 to T440s 2. run xrandr Actual results: DP2 connected primary 1024x768+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.00* 800x600 60.32 56.25 848x480 60.00 640x480 59.94 Expected results: All modes up to native one are listed.
