[Pkg-games-ubuntu] [Bug 1100780] [NEW] Cannot mirror display output between primary and secondary display

[Jarek Sobiecki]

Public bug reported:

I'm using LATITUDE E5510 laptop, on ubuntu 12.04 LTS

On gnome-control-center display, application properly shows maximal resolution, that works on my machine (1600x900). 
Resolutions detected on primary display includes only one resolution (1600x900).
When I plug secondary monitor, with different resolutions set supported, I cannot enable display mirroring (this option is greyed out). In secondary monitor, I can use few different resolutions.

I was able to work-around this problem, by simple adding resolution to eDP1 screen (primary display) with xrandr tool.
xrandr --addmode eDP1 "1280x1024"
After that, I was able to change resolution at gnome-control-center display applet to "1280x1024" on my primary display, and I was able to use mirroring feature. (both devices switched to 1280x1024 resultion).


It's not a critical problem for me (since my workaround works for me), but I think that fixing this issue can improve overall user experience.

If requested, I can provide lshw output (or other).

Best regards,
