Has anyone of you managed to get Bumblebee to work on the Blade 2018? I'm running Fedora 29 with KDE and I have trouble getting Bumblebee and Nvidia's proprietary drivers to work. I've followed these instructions, but every time I try to run a program with optirun, I get an error message. At first I got this error: Code: $ optirun phoronix-test-suite shell [ 164.635877] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NOUVEAU(0): [drm] failed to set drm interface version. [ 164.635903] [ERROR]Aborting because fallback start is disabled. Then I added this kernel parameter: nouveau.modeset=0 And now I get the following error: Code: $ optirun phoronix-test-suite shell [ 244.441784] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) [drm] Failed to open DRM device for pci:0000:01:00.0: -19 [ 244.441879] [ERROR]Aborting because fallback start is disabled. I then added these kernel parameters: acpi_osi=! acpi_osi='Windows 2009' As suggested here because the Blade has an American Megatrend BIOS. But then the touchpad doesn't work and I still get the same error... so I reverted the change. These parameters were supposed to fix a different problem anyway if you read the link... I'm not sure, but maybe the problem is related to Wayland. Or maybe the instructions to install Bumblebee didn't install the Nvidia proprietary driver correctly. When I run: cat /proc/driver/nvidia/version I get: "cat: /proc/driver/nvidia/version: No such file or directory" which kinda suggests that the Nvidia driver is not there. I'm running out of ideas. Any help is greatly appreciated!
