I am seeing this and I am on Ubuntu 19.10. I have an Nvidia 1660Ti with the driver 435.21. When I use Nvidia drivers, I do not see this issue. If I select the new "on-demand" option under Prime-Select or even the Intel(Power-saving) option, randomly but quite consistently I see that the display freezes. Mouse works, ssh works, nothing in the logs points to a cause though. The laptop is Legion-Y545 with Intel 9750h processor. Works fine on Windows where nvidia graphics card is used on demand and Intel discrete chip is used most of the time.
Major concern is the battery, while on intel chipset, I get really good battery but when I switch to Nvidia, it uses a lot of battery, I would want to be able to enable "on-demand" feature to save battery when needed. Latest Intel xorg driver is installed: 2:2.99.917+git20190815-1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/138094 Title: [Gutsy] desktop and keyboard freezes while mouse is moveable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/138094/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
