New xrandr mode in FC22
Hi!
Just switched to FC22. Having problems with the VGA port on my laptop docking station. If I connect the monitor directly to the VGA port on my laptop the monitor is recognized and resolution is set to 1920x1080. But if I use my docking station the monitor is unknown and I had to set the resolution manually using xrandr.
This worked for FC 21 & 22
xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA1 "1920x1080_60.00"
After that I was able to select 1920x1080 from display settings.
In FC22 the new mode shows up in the display settings combo box, but when I select it the display goes blank for a second and then the mode is changed back to the previous setting.

The monitor is a HP Compaq LA2306x with a native resolution of 1920x1080. Changing monitor does not help.
What is the recommended way of setting screen resolution these days?
