Intel 915 Integrated Graphics - Sluggish behavior in general

sp219 · 2009-02-15 23:46:23

I'm running Arch on an old Dell Laptop (Inspiron B130, to be exact)

Includes a 1.5 GHz single-core Celeron, 1 GB RAM, and Intel Integrated 915 graphics.

What would be the recommended configuration for optimal performance? Right now, I'm using the intel driver and the Xfce desktop environment. Some sites in Firefox (such as Facebook) seem to scroll rather slowly.

Is there anything I can do to get things running a little smoother? (Would the i810 driver provide better performance, or anything else for that matter?)

Thanks in advance.

* Edit: glxgears seems to be getting poor FPS:

[sp219@lap ~]$ glxgears

Any ideas? It almost seems like the window borders "come up" slower than the windows themselves... that doesn't seem right. Stuff in general just seems slow.

Also, I'm only getting ~400 fps with glxgears on arch, whereas ~1000 on an older ubuntu installation on the same machine

There are plenty of posts around about that. This is a known problem. Check for GEM, UXA and others. I tried to compile myself the latest drivers and got disappointed by the lack of stability. Gotta wait some more...

^benob, what version of xorg-server did you compile(I'm assuming you used the pkgbuilds from the "i965 with kernel..." or some such topic)? I always get an error concerning rrctrc

sp219 · 2009-02-16 05:12:44

Bah. Guess I'll have to live with it for now, then? Or are there some other (updated) drivers I can try?

Cheers.

Seriously, posting identical threads in two different areas is pointless. Not only do you litter the forum, you also split up replies which means that anyone looking for a solution to the same problem will have less of a chance of finding it quickly.

Yeah, sorry about that. Was going to ask a mod or admin to have the thread you mentioned moved here, because it seemed like a more fitting section. Oops.
