12.04.3 and 13.04 both use the 3.8 kernel. There may be a regression in the 3.8.13.5 kernel. Do you happen to know the kernel version you were running in 13.04? Can you run uname -a on the 13.04 system?
Also, it would be helpful to test a few kernel to confirm if this is a regression or not. Can you test the following kernels on the 12.04.3 system: 3.8.13.2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.2-raring/ 3.8.13.3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.3-raring/ 3.8.13.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.4-raring/ 3.8.13.5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.5-raring/ You don't have to test every kernel, just up until the first kernel that exhibits the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1218810 Title: video switch hot key will return "super key and p" and no response to switch video mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1218810/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
