I found out the problem. Two weeks ago I changed router. The old one uses 10.0.0.x LN IPs, the new one 192.168.1.x IPs. I have two printer, one of them is configured through IPP.
Freezes happened when it tried to contact that printer (but PC had a new IP number). I fixed it removing old printer from System->Administration->Print and creting a new one. In fact it's a bug anyway but it must be addressed to cups or other related package. Can someone confirm it please? -- Print Request Causes a Freeze https://bugs.launchpad.net/bugs/499999 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
