bbswitch module fails to start at startup #188

Open surajrv6 opened 5 years ago

surajrv6 commented 5 years ago

bbswitch module fails to load at startup. The module keeps unloading itself. Unable to use bbswitch with bumblebee. I am able to load the module manually using # modprobe bbswitch and also able to turn off and the graphics card. I am on Arch linux. I had the same problem in Debian (testing and stable) as well. I am using ASUS TUF FX504GD laptop I didnot try any boot options like acpi_osi...

Linux suraj-laptop 5.3.1-arch1-1-ARCH #1 SMP PREEMPT Sat Sep 21 11:33:49 UTC 2019 x86_64 GNU/Linux

eviltak commented 5 years ago

I'm facing the same problem. bbswitch unloads itself when started via /etc/modules-load.d/, but stays loaded (and is able to turn the card on/off) when loaded manually via modprobe.

surajrv6 commented 5 years ago

Hmm, I think maybe it is kernel related issue? Yesterday, I installed debian buster stable with kernel 4.19. Same problem except the nvidia card was not turning off in debian. I bypassed the laptop hanging issue by putting bbswitch load_state=0 in modprobe.d (instructions from bbswitch github main page) Didnt try Debian testing 5.0 kernel..
