I can confirm a very similar behaviour in my system. After upgrading from 12.04 to 12.10 I started to experiment some non random mouse freezes, in my case if I lift up the mouse from table and keep it for 2 seconds when I put it back on table it stops working (no cursor movement, no buttons response), even though the mouse remains powered (optical light remains on).
I've been using the same laptop and USB mouse for years without any problem and after this issue has started to bother me, I tested this same hardware in different Linux distributions without experimenting such problem. When the mouse stop working, unplugging and re-plugging, makes it get back to work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1019998 Title: 0461:4d51 Dell Laser Mouse stops working randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1019998/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
