Response delay since UP5 (NVidia graphics ?)

Postby jan_goyvaerts on Thu Sep 20, 2012 3:52 am

First of all: great job with UP5 ! It was visibly an extensive update. And it fixed the Nvidia twinview issue I had. A huge relief !

However, since UP5 there's a +/- 1 second lag in response. Typically for graphical things - I think. For example switching between tabs in Chrome takes a second each time. Also for switching between applications. That wasn't the case for UP4. But whatever the reason, I'd rather have a functional and slower system than a broken one. Which doesn't mean I wouldn't mind to fix this too of course. :-)

Is this a known problem ? I'm including the X conf file. Maybe there's an obvious flaw in there ?

This is the /etc/X11/xorg.conf as produced by the update. (Done by doing dist-upgrade by the way.)

Would you be so kind to read through this post?


I have a twinview setup also and it slows down my computer considerably. Xorg is eating 30% CPU on a dual core. Can you confirm that (run top or htop)? Do you use the TV out also?
