Is there any way to "roll back" a pacman -Syu update??


...because the latest Xorg is behaving stupidly on my system, and I don't think there's anything I can do about it.

Everything uses a lot more CPU time (compositing [Compiz], FF scrolling [anything with sufficiently large static CSS elements makes it stutter badly with CPU usage in excess of 50%, and this is on a multithreaded dual-core system! It did not used to do this!], etc.), mouse sensitivity has changed (with no way of changing it back, apparently; Xfce's "Mouse" dialog doesn't change anything anymore), and other things. Is there any way I can go back to Xorg 1.8, or am I stuck with this until the next Xorg update? Is there anything I can do in the meantime, if that's the case? I'm really clueless here; I have no idea what's causing these problems, much less where to look to fix them (config files? installing/uninstalling libraries? )

I was hesitant to do the update because I was afraid $#!t like this would happen...$#!t did happen. Am I stuck with it, or is there still hope for me?

thanks for the link...I didn't even think of searching the wiki; I was frustrated when I made the post. I managed to roll back Xorg to 1.8 successfully without trouble, as I still had the pkg.tar.xz file in the cache (now everything is back to the way it was CPU-load-wise ), but I'm in the process of trying to get my touchpad working again (probably just need to re-install the Synaptic touchpad driver). Hopefully I can get that going without too many issues.

EDIT: And...installing the older synaptics driver worked! Yay!

I'm about to test btrfs rollback support in F13 - been meaning to do it for ages. It's supposed to be automated with yum updates. Worked a treat on zfs on OpenSolaris for me.
Might be able to use something similar (in addition to the others) on Arch.

Hopefully you've learned to us the ARM website and all that. But as far as the real problem goes, what video driver are you using? Nvidia? It has known serious performance regressions with xorg-server 1.9 but is fixed in a beta version which should be available in [extra] soon. It is already available on the AUR.
