Slow Scrolling/Performance Problems

[Kyle Smith]

I am experiencing very slow scrolling while browsing the web. It looks like a slideshow. The problem exists in both Firefox and Konqueror. It seems worst in gnome, but it's still pretty bad in KDE. Gnome also seems slower in general (perhaps it's because of XGL?). Would updating Gnome to 2.14 fix it (and/or how do I do that)? I am relatively new to linux, so any help is appreciated. Thanks!

I'm on a dell inspiron 1200 laptop. It's got intel 915 integrated graphics with 256MB of ram. The part that confuses me is that the XGL animations aren't slow at all, but scrolling is. I should mention that I'm using Suse 10.1 and that I set firefox's browser.cache.memory.capacity to 16384, if that matters. I'm not on the machine now, so I'll post the X config. later.

I already tried buying more RAM, but this POS Dell will only accept memory that Mikey Dell personally blessed.<BR><BR>On a related note, when I login to gnome, my hard drive goes crazy for about 15 minutes. I disabled Beagle and that helped a lot, but there still seems to be something clgging up my system. The worst is when I open software management, which takes literally 20-30 minutes to start.<BR><BR>I've read before that linux doesn't suffer from hard drive fragmentation, but I can't help but wonder if that's a part of the problem. Are there any good defragmenters for linux that support reiser?

After several near catastrophies, I added Option "DRI" "true" to xorg.conf. Maybe it's placebo, but the scrolling is now suboptimal, but acceptable. I'll have to play around with strace later. Thanks for your help so far!<BR><BR>As far as the XGL, it gave me a warming to the effect of "Blah blah, I don't recognize your hardware", but I ignored it and it seems to be working fine. The only time it slows down is when I have the rain effect on and I try to wiggle windows.

Holy Shi-ite! I found a 256 stick that was compatible, and now everything is tremendously faster. The software management now opens in 3 minutes instead of 30. The jury's still out on the scrolling.<BR><BR>Edit: Would upgrading Gnome to 2.14 help with performance? If so, how do I do that?
