I have two screens, both 19", 1280x1024 resolution, and one of these is
an (old) Dell screen with Pivot rotation possibilities.
It works pretty good, my lightdm gets the screens properly, (thanks
to a xrandr setup described below), but when logging into Xfce the
screens blinks black, and after this the screens shows the same desktop
setup as the "Clone" alternative in Nvidias TwinView does. Either using
nvidia-settings, or the script described below, I can simply setup my
screen again as I want them, but how can this be done without having
to? - that is, make the Xfce log-in/startup not mess with the screen
setup that is correct in lightdm?
To be really clear about my setup, I have my screens like this:
(Use a monospace font to view this...)
------
-------- | |
| | | |
| | | |
| | | |
-------- ------
1280x1024 1024x1280
And this is on a Nvidia 650Ti Boost card - I use the proprietary
drivers from Nvidias homepage (319.23) on a Wheezy installation. (I
don't believe the drivers packaged in Wheezy supports the card)
I use lightdm as display manager, and in that I have setup so it runs a
script to setup the screens using the display-setup-script
in /etc/lightdm/lightdm.conf:
display-setup-script=/usr/share/rotate_pivot_90.sh
rotate_pivot_90.sh simply looks like this:
#!/bin/bash
xrandr --output DVI-D-0 --mode 1280x1024 --rotate left --pos 1280x0
--output DVI-I-0 --mode 1280x1024 --pos 0x256
(DVI-D-0 is the right (pivot) screen, and DVI-I-0 is the left
"standard" screen) What causes logging in to Xfce to reset the screen
setup that is correct in lightdm?
My goal is to not have to do anything, and get the described setup
automatically on login (even after lightdm).
My xorg.conf is available here:
