Hi, I have Arch Linux in this system:
-video card: nvidia 6150
-monitor 1: LG, 1440x900 (right side)
-monitor 2: Samsung, 1360x760 (left side)
-desktop environment: Lxde
1) no matter how hard I try, write to xorg.conf, set up and reboot, the
monitors' positions are always changed in NVIDIA X Server Settings (the
graphical tool).
I am using the open-source nouveau driver, not the nvidia driver from
the vendor. Don't even use the "NVIDIA X Server Settings", esp. if it
causes trouble.
I propose you use
* software: A fairly new X11 (1 year old is OK)
* config: No xorg.conf at all
* driver: This should load "nouveau" for your card. Verify by reading
/var/log/Xorg.0.log carefully (it's confusing at first)
* xrandr: Your monitors will by default both show the same picture.
o In GNOME, you could run Settings | Screen settings, LXDE should
have LXRandR, which gives you a GUI tool to configure xrandr.
But the change will unfortunately not be permanent.
o In a terminal inside the running X11, run "xrandr". That shows
you your monitors, their connection names (before "connected",
e.g. "DVI-I-1" or "VGA"), and their resolutions.
o Again in a terminal in X11, run something like "xrandr --auto
--output DVI-I-2 --right-of DVI-I-1". You should see the result
immediately. If it works, put that line in
/etc/X11/Xsession.d/45custom_xrandr-settings and chmod 755 that
file. Restart X11 and the monitors should still be in this config.
For more info, just search the web for "xrandr"
