Re: [RP] [RFC v3] Add xrandr support

[Rob Paisley]

All:

I run three monitors, two vertical and 1 horizontal.

My login manager mirrors the two vertical monitors and ignores the horizontal
one.

Upon login, I open a shell in ratpoison (1.4.6), turn my head sideways
(improper rotation of monitors) and type "sh bin/rotate.sh && exit

rotate.sh is as follows:
xrandr  --output DisplayPort-0          --auto --rotate left    --primary \
        --output DVI-0                  --auto --rotate left    --right-of      
DisplayPort-0 \
        --output DisplayPort-1-1        --auto --rotate normal  --left-of       
DisplayPort-0

Then run ratpoison's newwm with ratpoison as the argument. This causes
ratpoison to re-detect the screens and I continue my workflow normally
with everything in harmony. ratpoison shows three screens, and I move
between them with nextscreen/prevscreen as usual.

This beta starts the same (as expected). The two vertical monitors are
mirrored and incorrectly rotated. I expected that when I ran my xrandr command
not to have to re-exec ratpoison to get directly to a correct setup. No
change.

I tried the newwm command and that seems to have decided that all three
screens were one really big screen.

Here's what I see from 'ratpoison -c sdump -c fdump' at various times.
before: Right after login
xrandr: After I've run xrandr from above
after: After I've issued "newwm ratpoison"
