Just installed brand new laptop Dell Vostro 3300 with Kubuntu 10.04 and 
upraded to KDE 4.4.5. Some hickups but mostly good.

Yesterday for the first time connected a monitor to the VGA-out and not 
a good result. I get this "flickering, vibrating" output that seems 
related to refresh rate and it can easily give you a nasty headache.

Have tried upgrading to xorg-edgers ppa drivers, no difference. Tried 
upgrade kernel to 2.6.35 via ppa. No difference but broken broadcomm 
wireless drivers.

Anyone heard of this? Yes the built-in 13.3 is brilliant but I like to 
use a larger monitor at work.

best regards
Sinclair
