We would need to see the system log from one of those failed boots. To do that please:
1. Reproduce a failed boot with nvidia-340. 2. Uninstall nvidia-340 and after rebooting collect the log from the previous failed boot. For example, to collect the last three boots run: journalctl -b-1 > prevboot-1.txt journalctl -b-2 > prevboot-2.txt journalctl -b-3 > prevboot-3.txt and then please open a new bug with those logs attached. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1889377 Title: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1889377/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
