I am running testing and have used bumblebee for years. Now it stopped working.
I have tried to reconfigure my system using the guidelines from https://www.pcsuggest.com/install-and-configure-nvidia-optimus-with-bumblebee-in-debian/ and https://www.pcsuggest.com/nvidia-optimus-troubleshooting-in-debain-kali-linux-ubuntu/ but this is the output after doing all those things - the same as before I started: Now this happens: optirun -vv glxgears [ 433.449756] [DEBUG]Reading file: /etc/bumblebee/bumblebee.conf [ 433.450298] [DEBUG]optirun version 3.2.1 starting...
