Linux Mint 15 x86
I have a laptop HP NC8430 plugged into a docking station (DVI -> HDMI Out), plugged into a Yamaha RX-V565, output via HDMI to a Samsung BX2450 LCD Monitor.
I am having an issue with the resolution detected / set at the MDM login screen which is automatically picking up the LDP resolution (16:10, 1680x1050) when I have my external LCD monitor (16:9, 1920x1080) On and the laptop lid closed. Unfortunately, the Yamaha only accepts VGA table resolutions or 16:9 resolutions so outputting 1680x1050 causes blank/flicking screen where I see the display for 0.5 seconds before showing snow or blank output. Display mirroring seems to be the culprit.
When I can eventually set the resolution (takes up to 15 mins a go) via click and guess, it works great.
Is there a way of setting the resolution of MDM / Login screen to 1280x768?
Or is there a way of setting the maximum resolution of the LDP to 1280x768?
Display mirroring is getting forced ON if I undock / re-dock either live or between reboots, can this be disabled permanently?
