[SOLVED] dual screen on KDE 4.2 (but works on other WM)

I have recently (yesterday) upgraded to Xorg 1.5.3 (as posted here, this was a call to test it (http://blogs.gentoo.org/remi/2009/02/). It all works nicely and decided to jump also from KDE 3.5.10 to KDE 4.2.1. It is working properly on one screen but not the second one. X sees both screens fine, any other WM works (Gnome, XFCE...) but not KDE 4.2.1. Same X configuration perfectly worked on KDE 3.5.x

I have seen a few posts on this forum from people stating that dual screen on KDE just doesn't work. Can anyone confirm this? This should be treated as a bug in my view.

Thanks for any reply,
Steph

I'm afraid I can't be of much help...but...
I have KDE 4.2.1 working on two screens using nVidia TwinView, laptop 1440x900 as primary, 1650x1080 LCD as secondary.

My problem is when undocking the laptop and restarting X, splash-screen comes up and then nothing, splash fades to black screen without any errors and no kwin. I have no clue this far but are going to try to track down errors tomorrow.

This far, 4.2.1 + qt 4.5 + xorg-server 1.5 seems to be much more fragile then 4.2.0 + qt 4.4 + 1.3 xorg-server. Lots of little stuff not working correctly or crashing my whole setup. Xorg option BackingStore "true" crashes X and kde on every right-click, this worked great in my old setup even using 180.35 driver (running 180.29 now though since the consensus on 180.35 seems to be that it causes a lot of problems)

I think I have gotten everything to work as it should now using the xorg.conf below.
The machine works both docked and undocked now, now all I have to do is solve all the other little irritating things in 4.2.1.

Hello,

Indeed, the use of twinview fixed it for me. Although it overall seems slightly slower.

Cheers,
Steph

Hi

Since I posted my xorg.conf I have been having problems with stability of X.
This stability problem was solved by removing...
