kdemod 4.2 and dual head

I am trying to setup dual monitor in kde 4.2. I ran the command

xrandr --output DVI-0 --right-of VGA-0

but it doesn't work, I get an error msg

Xlib:  extension "Generic Event Extension" missing on display ":0.0".

. Doesn't kde 4 support dual head?

Re: kdemod 4.2 and dual head

what videocard are you using?

I have kde4.2 running smoothly on my nvidia-card with twinview

It's not yet perfect but it runs fine, there are still some problems if you want to use panels on both screens.

Also watch out with gtk-qt, here there are problems with gvim, openoffice, ... if you use it select the gtk style kde4-oxygen, then everything works fine

Re: kdemod 4.2 and dual head

Same issue here.  I'm using ATI Radeon HD 2400XT, my error is slightly different:

Xlib:  extension "Generic Event Extension" missing on display ":0.0".
xrandr: screen cannot be larger than 1600x1600 (desired size 2560x1024)

I understand that "Generic Event Extension" error is common, and generally thought of to be harmless?
