Re: Debian+KDE 4.4.3 (i915 dual screen) (SOLVED)
Xserver has a well known issue with the i915 driver and it's DRI/DRM
limitation to 2048x2048 window size. So the default setup is not working
because in recent versions of X it loads drm by default creating
configuration that allows only "clone" of the primary display with DRI
enabled on it.
The impact on kde is that it can not set dual display (only "clone" option
SOLVED: applying custom xorg.conf with
Option "NoAccel" "true"
in the device section and Position Option into each monitors config.
