The issue is not keyboard related, I would risk saying. The freeze does not happen exclusively on app switch, it's just an easy way of triggering it. A much better guess is the graphics card.
Inspired by a lost post on Ubuntu freezes, I installed the latest Nvidia drivers, 275. https://launchpad.net/ubuntu/oneiric/+source/nvidia-graphics- drivers/275.09.07-0ubuntu2 So far, so good. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/733374 Title: X freeze, nvidia-current, Ubuntu 10.10 Maverick GeForce 9600GT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/733374/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
