Thanks for the bug report. This sounds a power management problem. 1. If you have 'tlp' installed the please uninstall it. It's known to cause bugs like this.
2. Try installing 'powertop' and then look in its 'Tunables' section. By changing some of those to 'Bad' (which is actually better than 'Good' in this case) you can stop them suspending so much. 3. The kernel team should have some more ideas. I will move this bug there... ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912670 Title: Mouse buttons and keyboard unresponsive after idle time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912670/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
