I'm experiencing very slow scrolling with firefox on sites like
http://www.roadrunnerrecords.com/blabbermouth.net/
http://www.vai.com/News/index.html
I'm running 64 bit with KDEmod. Scrolling is fine when I remove flash completely but on Ubuntu 10.04 (64 bit) the abnove sites scroll fine on a different machine (with intel graphics). I read somewhere by modifying xorg with "AccelMethod" "EXA" to "XXA" scrolling becomes very smoth onm ATI and Intel. Here is my xorg.conf:

is there something I can change to improve scrolling in firefox? I've tried to turnoff desktop effects and scrolling is the same annd also running firefox from a fresh profile. Hence, i suspect my nvidia 9800GT card to be the culprit. If anyone has a working xorg.conf with nvidia, 64 bit and smooth scrolling on the above mentioned sites please SHARE! Many Thanks!

Check your setting - there should be "Smooth scrolling" etc.
The other machine, w/ intel graphics - are you using KDEmod and the same settings as on this one?
What driver are you using?
[OT]
'AGPFastWrite'?? Is it an AGP card? ;-)

Yes I'm using the same settings on the other machine. No, it's not an AGP card (PCIe).

> No, it's not an AGP card
So what are those settings doing there? :-)
What driver are you using?
Did disabling / enabling smooth scrolling etc. change sth?
Offline
Using the binary nvidia blob driver. Removing the option did not do much to scrolling. I have turned smooth scrolling on. Turning it off improves scrolling a little but not by much. It is still very very slow. If anybody has a good working xorg.conf with nvidia please post or any other suggestions please post.

Have you tired w/o the xorg.conf? xorg-server 1.7 doesn't require it to work - do you have anything special in there?
Offline
No haven't tried it. My xorg.conf is posted above in the first post.

The ideas I'm posting here are just wild guesses but it's relatively easy to try them all out before performing some mayor surgery.
You can try a different driver but of course it can fix one thing - scrolling - and scr*w another.

Tried it now and that worked. Running without a xorg.conf buty now I can't turn on desktop effects in KDE. How do I set that up?
Offline
How do I determine what driver xorg is using now that I'm running without it xorg.conf?
Offline
lsmod | grep nvOffline
lsmod | grep nv
Many thanks!

Sorry, I don't use KDE, but it may be related to how do you start KDE: from xinit or via KDM or sth.

It's running the same driver as before.

Did you uninstall it? Did you install the nouveau driver? 'pacman -Qqs xf86-video' will tell you what drivers you have installed.

No, I don't have the nouveau driver installed. I have to check if I have the nv driver installed but I didn't uninstall the nvidia driver. I'm starting KDE via xinit.

@karol gave me the right hint
i'm running open suse but had the same problem.
I went into
about:config
Changed:
general.smoothScroll
from true to false.
For me it was anything but smooth. This isn't an old computer either!
Cheers
