Description Jamie Kitson 2012-04-02 02:39:49 UTC

With my Asus Zenbook UX31E (Intel HD Graphics 3000) when I plug an HDMI device in and run xrandr
everything is fine and both laptop and external HDMI monitor work.
However, when I disconnect the HDMI device and run xrandr again it
gives the following errors and both screens go off.

[jamie at jamie-laptop ~]$ xrandr --output eDP1 --auto --output HDMI1
--auto --above eDP1
xrandr: Configure crtc 0 failed
X Error of failed request:  BadMatch (invalid parameter attributes)

When both are connected and working:

Sorry ignore that, I thought I was commenting on another bug.
