I have been given an almost 7 year old IBM TP600E and have managed to get Archlinux-0.7.1 installed and subsequently updatedt via pacman -Syu to 0.7.2. I have come to like this setup a lot but there is one thing that bugs me. The video performance of the arch system is jerky and unsatisfactory, I know the hardware is capable of more since with Knoppix-4.0 it's performance is a lot more snappy and smooth. Funny enough the fps-values ("frame per seconds") of glxgears is identical on Knoppix and Arch but the wheels churn smoothly in Knoppix and extermely irregurarly and jerky in Arch. I have found instructions on the web recommending the replacement of the actual "buggy" xorg driver for the neomagic video card with an older xf86 version. I have manged to find binaries for two previous versions but not the sources. I have renamed and inserted the older drivers but with no success. I get scores of "unresolved symbols" messages. I would compile and install via ABS pacman if it wasn't for the lacking sources.
How would I have to handle the the alternate binary drivers to get them to work and where or how would I find/extract the respective sources, or am I to resort to an older distro that still employs xf86? I will try hard to avoid that.

This is a shot in the dark but maybe startx -- -ignoreABI works? i'm not 100% that's the syntax but if it isn't you could always put it in /usr/bin/startx under 'defaultserverargs'
about source: is this it?

startx -- -ignoreABI is the right syntax but didn't work, thanks a lot for the link to the sources, everything there I was looking for.
I'll try to "makepkg" this week

Hi, I had the same problem with Neomagic MagicGraph 256AV.
Performance with vesa driver was better than with neomagic driver. THen I tried changing my xorg settings in /etc/X11/xorg.conf - in the screen section, I changed DefaultDepth from 24 to 16 and the same again in the Display subsection. Now neomagic is no longer jerky.
I suspect that's the reason Knoppix appeared to give better performance with neomagic drivers... because the default depth was lower.
I was happy with vesa at depth 24 until I found the following problem: when switching from X to virtual console and back, the brightness was reduced for no apparent reason. With the neomagic drivers that doesn't happen... see this topic:
