Title:
[GM45] xrandr does not enable external display after suspend/resume
cycle
Status in “linux” package in Ubuntu:
Expired
Bug description:
An external monitor is connected to the VGA port of my Thinkpad X200
Tablet laptop. Before the laptop is suspended, I can give an xrandr
command to set up a dual-head configuration. After resuming from a
suspend, xrandr does not turn on the external display even though it
seems to arrange the outputs logically within the virtual screen. The
external display starts to work if I switch to a text console by CTRL-
ALT-F1 and then back to X by CTRL-ALT-F7. This problem can cause
window managers such as mutter and compiz to crash if the screen
configuration gets changed while they are running.
How to reproduce:
$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192
LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm
1280x800 60.0*+
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 connected (normal left inverted right x axis y axis)
1280x1024 60.0 + 75.0
1024x768 75.1 60.0
800x600 75.0 60.3
640x480 75.0 60.0
720x400 70.1
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
HDMI2 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)
$ xrandr --output LVDS1 --mode 1280x800 --panning 0x0 --output VGA1 --mode 1280x1024 --above LVDS1 # at this point, VGA1 is turned on normally
$ xrandr --output VGA1 --off --output LVDS1 --mode 1280x800 --panning 0x0 # back to single-head configuration
$ sudo pm-suspend # laptop is suspended and resumed
$ xrandr --output LVDS1 --mode 1280x800 --panning 0x0 --output VGA1 --mode 1280x1024 --above LVDS1 # now VGA1 is not turned on; one needs to switch to a text console and back to X to enable VGA1
