[ubuntu-studio-users] Screen resolutions

Another useful tip I found when using more than one non-identical 
displays (ie diff native resolutions)
also install xrandr along with arandr.

Then pick the largest screen resolution you want, find the scale ration 
between what you want and each of the native resolutions and use the 
xrandr command to adjust them. Once adjusted use the arandr GUI to drag 
and drop the different outputs where you want them to be (ie side by 
side etc)

use xrandr by itself in a terminal window ( might need to use sudo or 
root)  and it will display the list of display output names.

then using the scaling ratios you calculated run
xrandr --output [displayID-1 from above list] --scale WratioxHratio
xrandr --output [displayID-2 from list] --scale WratioxHratio

the screens will jump and change and look a bit weirdly displaced; then 
run arandr from a terminal window and when the GUI opens drag and drop 
the display outputs where you want them.

only drawback is once you logout and log back in you have to go through 
the two xrandr commands and the arandr drag and drop again. Works for me 
as I just let the PC idle power up all the time so not a biggie problem. 
Am still looking for a straightforward way to save the setting so reboot 
is fine; haven't run across it yet.
