Package: bumblebee Version: 3.2.1-20 Severity: normal Hi,
(I am not sure bumblebee is the right package, but it is not clear to me whether the problem stays with bumblebee, nvidia drivers or what else; feel free to reassign) my discrete graphics card is (according to lspci) a "NVIDIA Corporation GP107GLM [Quadro P2000 Mobile] [10de:1cba] (rev ff)", mounted on a Dell Precision 5530 laptop. If I configure bumblebee to use "bbswitch" as PM (which, I believe, is what I should do), optirun is unable to work: $ optirun glxinfo [ 383.435979] [ERROR]Cannot access secondary GPU - error: Could not enable discrete graphics card [ 383.435997] [ERROR]Aborting because fallback start is disabled. After this command, module bbswitch is loaded and module nvidia is not. Also, these lines are sent to syslog: Feb 20 18:11:12 amalgama bumblebeed[1044]: [ 436.831559] [ERROR]Could not enable discrete graphics card Feb 20 18:11:12 amalgama kernel: [ 436.860809] bbswitch: enabling discrete graphics Feb 20 18:11:12 amalgama kernel: [ 436.860828] pci 0000:01:00.0: Refused to change power state, currently in D3 If I try manually to modprobe nvidia: # modprobe nvidia modprobe: ERROR: could not insert 'nvidia_current': No such device modprobe: ERROR: ../libkmod/libkmod-module.c:979 command_do() Error running install command for nvidia modprobe: ERROR: could not insert 'nvidia': Operation not permitted Also, the following lines are sent to syslog: Feb 20 18:11:44 amalgama kernel: [ 468.637860] version 39.2 Feb 20 18:11:44 amalgama kernel: [ 468.639277] ipmi device interface Feb 20 18:11:44 amalgama kernel: [ 468.648299] nvidia: module license 'NVIDIA' taints kernel.

Feb 20 18:11:44 amalgama kernel: [ 468.727130] nvidia-nvlink: Unregistered the Nvlink Core, major device number 240 The only information I manage to find about this README is here[1], and mentions that I should upgrade to a new kernel. But I am already running basically the latest one (4.19.0-3-amd64), so this is probably a false trace. [1] https://us.download.nvidia.com/XFree86/Linux-x86_64/410.93/README/knownissues.html However, I have noticed that if I disable PM in bumblebee (set PMMethod to none) and restart my system, the module bbswitch does not get loaded (correct), the module nvidia gets automatically loaded (probably correct), GDM3 starts with Xorg instead of Wayland (not really correct, but probably not fundamental) and optirun works, running perfectly FlightGear at top FPS. Optirun stops working after suspending the system, but seems to survive hibernation. Of course, if I re-enable bbswitch either within bumblebee configuration or manually loading the module, everything stops working until the next cold reboot. I am running from an up-to-date unstable, in particular with nvidia drivers version 410.93-2. I am available for doing further tests, as I really would like to fix this problem and use my discrete card without having to cold-reboot. Thanks for maintaining bumblebee!
