Public bug reported: I am not sure that it is something that an issue caused by nvidia-prime or if it is something that is cause in the drivers or if it is a bug with the kernel itself, cause it seems to be a problem with Linux PM, so this bug could be moved if needed
*** What's Wrong? *** As the title states, I am unable to use the Nvidia GPU when I have changed profile for intel then computer on suspend for more than 30 minutes ( This has to be determined precisely how long until I get the issue ) and then set back the profile to nvidia. So basically, it seems that the nvidia modules are unable to be loaded, I have tried to fix the issue using bbswitch. It doesn't work neither, if the /sys/bus/pci/devices/0000\:01\:00.0/power/control is set to auto, I am unable to load the kernel modules anymore. *** What do I expect *** Well, I was hoping that I would be able to keep my laptop on and simply switch from one GPU to other seamlessly. It is, until I put my laptop on suspend for an extended time while I am on powersaving mode ************************ ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: nvidia-prime 0.8.10 Uname: 5.0.0-14-generic #15-Ubuntu x86_64 NonfreeKernelModules: nvidia_uvm nvidia_modeset nvidia Architecture: amd64 CurrentDesktop: MATE CurrentDM: GDM3 Date Thursday May 2nd 2019 7:49 PM InstallationDate: Installed on (0 days ago) SourcePackage: nvidia-prime UpgradeStatus: No upgrade log present (fresh install) Description: Ubuntu 19.04 Release: 19.04 nvidia-prime: Installed: 0.8.10 Candidate: 0.8.10 Version table: *** 0.8.10 500 500 http://ca.archive.ubuntu.com/ubuntu disco/main amd64 Packages 500 http://ca.archive.ubuntu.com/ubuntu disco/main i386 Packages 100 /var/lib/dpkg/status /var/lib/dpkg/status -> https://paste.ubuntu.com/p/McmJHRgjTH/ https://paste.ubuntu.com/p/Pxnw7mDmzQ/ -> dmesg before issue **** MORE dmesg will come, need to get fresh data! ***** ** Affects: nvidia-drivers-ubuntu Importance: Undecided Status: New ** Affects: nvidia-prime (Ubuntu) Importance: Undecided Status: New ** Also affects: nvidia-drivers-ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827446 Title: Unable to switch back to nvidia after suspend on intel To manage notifications about this bug go to: https://bugs.launchpad.net/nvidia-drivers-ubuntu/+bug/1827446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
