No persistent change of screen resolution

[Hadmut Danisch]

Hi,

I'm running a 12.04.01 on a Macbook Pro with retina display under Virtualbox. Because of it's extremely high resolution, virtualbox scales it down and runs it with half the width and height of the panel, projecting each guest pixel onto four of the hosts's screen. Works well.

Ubuntu's desktop manager login screen works well with this and chooses the correct resolution.
(
But then xfce chooses a higher resolution, thus moving parts out of the display.

This can easily be fixed by setting the needed resolution with xrandr or the XFCE screen settings. But these changes are not persistent. I have to repeat them after every boot of the guest machine. Even adding the xrandr command to the startup scripts of the XFCE session has no effect.

There seems to be no way to make resolution settings (no matter whether with xrandr or XFCE's graphical setting programs) persistent.

I meanwhile found the problem. It was the monitors.xml, which contained a wrong resolution (too high). I had to manually change them with a text editor. This solved the problem.

I assume this was fixed at some point due to improved HiDPI support.

However, if this particular issue is still reproducible, we will reopen the report.
