Comment 15 for bug 565981

I tried both the ppa's
https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-updates (xorg-server - 2:1.7.6-2ubuntu7~xup)
https://edge.launchpad.net/~sarvatt/+archive/bugs/+packages (xorg-server - 2:1.7.6-2ubuntu7.5)

Both cause severe problems for me and couldnt use the system for more than 5mins.
Everything would lockup at some compiz use and i can not do anything , the screen just froze and I couldnt return to VT nor did Alt+SysRq+K help.
Hard to hard shutdown the system.
Probably not of much use but , from /var/log/messages http://paste.ubuntu.com/419425/ http://paste.ubuntu.com/419432/
[i had to hard shutdown nearly 10times , seems the SAK worked a couple of times in the background , but the screen was frozen ]
