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 Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/138094 Title: [Gutsy] desktop and keyboard freezes while mouse is moveable Status in xorg package in Ubuntu: Fix Released Status in xserver-xorg-video-intel package in Ubuntu: Fix Released Bug description: Binary package hint: linux-source-2.6.22 I am not sure if it is kernel problem but it seems so. I had this two times in Gutsy. After some time the desktop and keyboard freezes while the mouse is still move able but nothing reacts to clicks. Another interesting point is that the first time an audio file runs along without problems in totem until it finished and the second time a video in vlc window. I could watch it normally except that I had no influence. The only keys that are still working are acpi ones like brightness (which calls sonybright acpi scripts) and the hibernate button. The laptop really went down to sleep without problems and resumes fine but it was still not possible to do anything. The video runs along too after resume except the audio but this is a general gutsy problem (under normal circumstances I had to restart the video program to get sound again). I have a Sony TX2 Laptop with Gutsy and the latest updates. I am using compiz and the i810 driver because of the intel xv problem. I have heard in #ubuntu+1 that I am not the only one with this problem so it doesn't seem to be only hardware specific.
