I've just installed jaunty, fresh install. New hard disk. Previously I was on Hardy.
I copied over my xorg.conf file (it was exactly as I liked it, but it failed to work. After a little digging however, I found I needed to change the driver from i810 to intel.
Things still aren't as I like them though, I like to be able to zoom. And ctrl-alt-+ and - do nothing. ctrl-alt-backspace didn't either but I managed to turn that off with DontZap off. Dontzoom off however hasn't helped.
I'll attach my xorg.conf at the end.
Other problem... in Hardy, there was a neat little app that could configure compiz to turn on/off all the effects... I can't find it in Jaunty. I WANT MY CUBE BACK!
The zoom thing is most important though, I like sitting back and without that I have to lean forward just to read the screen sometimes.
