another thing that may help - programs like Blender are running a lot slower than they used to.
Also, decided to check my yum.log. I recently updated:
Mar 14 14:19:49 Updated: xorg-x11-server-common-1.5.3-15.fc10.i386
Mar 14 14:25:18 Updated: xorg-x11-server-Xnest-1.5.3-15.fc10.i386
Mar 14 14:25:23 Updated: xorg-x11-server-Xephyr-1.5.3-15.fc10.i386
and before that:
Mar 09 00:56:47 Updated: xorg-x11-drv-synaptics-0.15.2-4.fc10.i386
Mar 09 22:51:19 Updated: kmod-nvidia-173xx-22.214.171.124-170.2.35.fc10.i686-173.14.1
Since I posted the first post in this thread on 14 March, those updates on 14 March are suspect. But are those specific packages likely to be culprits? How could I roll them back to test?
