I got upgraded back to 470 because new 460 transitional dummy packages were released, which caused the upgrade. I could have prevented that via apt-mark hold.
When I was getting these problems with 470 I had nvidia.NVreg_PreserveVideoMemoryAllocations=1 in my kernel command line, via /etc/default/grub. After being upgraded to 470 again, I changed that to nvidia.NVreg_PreserveVideoMemoryAllocations=0. So far, waking from sleep has been reliable. (Also, neither Firefox nor KDE Plasma have problems after sleep with this. I had set that option to 1 in the past because it seemed to help with earlier versions of Firefox and Plasma.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1946303 Title: No video after wake from S3 due to Nvidia driver crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470/+bug/1946303/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
