USB to DVI DisplayLink with OpenSUSE 12.2 and KDE with xrandr / KRandR

I’m currently using the opensource Nvidia driver, Nouveau on openSUSE 13.1, for my system and I can get my USB DisplayLink to work using all the aforementioned steps:

  • Blacklist the udlfb driver in /etc/modprobe.d/50-blacklist.conf
  • I executed in terminal: xrandr --setprovideroutputsource 1 0
  • Using kscreen, activated the 3rd monitor labeled “DVI-1”

The screen activates without a glitch. The problem is, my screen refresh seems to drop to like 60 frames per minute. Same issue I had with using the ATI card machine.

I wonder if there is some sort of synchronization that is going on between all the displays.

Any ideas?
