As on title... it crashed out very suddenly. X restarted and prompted login.
I think you made a good job with 180.37 perfomances are better, but I think there are some reliable fundamental that must be solved as soon as possible, I posted about it in other threads.
Now X restarted but the system has a different behavior it's more laggy... I think the problem is a website!! www.tim.it
obviously I'm not doing advertisment so if you want to remove, no problem, anyway I've lot of trouble browsing that site...
