I have a laptop. I have a VGA monitor. I want to use them together.
The native panel (LVDS1) is 1600x900. The monitor (VGA1) is 1920x1080
and sits to the right of my laptop. intel graphics, amd64 -current.
When I start X, by default I have a mirrored display of 1024x768. I
want 1600x900 on the LCD, 1920x1080 on the monitor, and for the
desktop to extend from the latop to the right onto the monitor. I
would also like for my fonts to have somewhat predictable sizes and
not engage in crazy dpi hijinks.
To accomplish this, I have found some combination of the following
xrandr commands works:
xrandr --auto
xrandr -s 1600x900
xrandr --output LVDS1 -s 1600x900
xrandr --output VGA1 -s 1920x1080
xrandr --output VGA1 --right-of LVDS1
xrandr --dpi 96
The problem is that running these commands in any particular order
doesn't always work. I have to run random permutations of them until
everything is correct. Sometimes the commands do nothing, sometimes
the monitor just goes blank, sometimes the command does exactly what I
want it to do.
Is there a single command I can put in .xinitrc? A single correct
sequence of commands?
It's been a while since I had dual screens set up, but my script
basically did sth like:
xrandr --output VGA1 --auto
xrandr --output LVDS1 --auto
xrandr --output VGA1 --right-of LVDS1
Don't know if issues can be related to specific hardware or if any
recent changes would make it not work though.
