I formatted 10.10 and installed 11.04 today. My PC is kind of old so I'm using Ubuntu Classic. First time I booted it worked really nice, with the shortkeys, snap-function and improved workspace switcher. But after installing some software and updates and rebooting, I am being forced to 'No Effects'-mode (without any warning or notice). I have no clue why, and afaik I've installed nothing gnome/appearance-related.
I did try
rm -rf .gnome .gnome2 .gconf .gconfd .metacity
to reset all gnome-settings, but that didn't help.
Does anyone know how to fix this?

setsid compiz --replace
) it ran fine anyway. I wanted to make it permanent, so I took the following steps:Safety first, so make a backup of the file:
Then edit the file with:
Remove the last 3 lines, being:
So the file now only contains:
After saving the file, it boots to Ubuntu Classic, including Effects :D
