1) Make sure you are using the nvidia-340 driver, which is what your card requires. Newer Nvidia drivers probably won't work with that card. If you still get stuck with a system that doesn't boot properly then please open a new bug about that.
2) The freezes appear to be bugs in the nouveau driver, which is a common problem. It's not a stable and reliable driver for many cards. That why I recommended the Nvidia proprietary driver. A simpler solution, perhaps, is to just get a newer Nvidia card that is supported by the current Nvidia drivers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
