This crash happened when I tried to open a game, I haven't tried to open anything else using the Dash, the others wer opened from the Launcher.

It looks like this has returned with vengance, updating this morning asked for a reboot and after entering password the display clears then seems to freeze, no interface at all, I can open the terminal via CTRL+ALT+F1 but I can't see where to go to get the interface running. I'm not sure how to report the system status from there and am using my normal 11.10 system to report this, it may have been reported under another bug but without reading all those since Thursday (the last date updated the failed system) so any advice will be investigated. Thanks
John

Hmm, everything works fine for me after todays upgrades.

After The most recent updates, My entire Homepage seems to be very unstable
and flickers like a strobe light... Everything seems to work fine It just
doesn't seem to render fine... It might be just my netbook, but does anyone
else have any instability on their desktop??

You could try renaming the .gconf and .config/dconf folders.

I don't understand. Rename to what? How does it help?

Rename them to .gconf.old and dconf.old. Then log out and log back in again. This should cause gnome/Unity to revert to default settings.

Wow, thanks. This really solved the problem. :)
