Awesome. I'm glad things are working out. Independent verification is a good thing!

Blessed be!

Ok I found the cause of the slowdown. Seems there is a bug in the current stable xorg that causes issues with nvidia-drivers and compositing if you have it enabled in xorg.conf

So the workaround is to type this in the terminal as your normal user:

Code:

nvidia-settings -a InitialPixmapPlacement=2


By doing this my terminal now comes up instantly with absolutly no hangs durring resize or moving. My other windows now open much faster as well.

You need to issue this command each time you log into your xsession so I created a small startup script called nvidia-fix that I run in my Xfce4 autostarted applications list:

Code:

#!/bin/bash

nvidia-settings -a InitialPixmapPlacement=2



hope this helps anyone with the same issues.
