Package: bumblebee Version: 3.2.1-10 Severity: important Dear Maintainer,
I routinely run my laptop on sid (I need to compile scientific software using recent versions of just too many libraries), usually with no problems, or simple ones that a relatively old hand at debian system administration can solve easily. However, recently I was hit by nasty bug that resulted from a combination of package updates, so I don't know exactly which package is to blame. I am filing the bug raport on bumbleee because I was able to work around the rest of the problems, but maybe it's not bumblebee's fault. If you can determine that some other specific package is to blame, do feel free to move the bugreport to that package. In short: after some recent upgrade of xorg and nvidia, glx support was completely broken on my system. It stopped working both on my primary Intel graphic card and on the nvidia optimus. This caused a mess, since I used gnome and gdm3, and I was left with no working display manager, and no easy way to enable network connections via network-manager. However, after some manual configuration, I got the network on, and was able to run lightdm and the mate desktop (thanks heaven there are still some desktop environments that don't depend on glx!). Thinking that the glx alternatives may have been messed up by the upgrade, I removed completely all nvidia packages from my system, and also glx-alternatives itself. This meant also removing all nvidia dependencies, including optimus. This fixed glx on my primary display. So now I had again working gdm3 and gnome. Then I went on to reinstall bumblebee and nvidia packages. The install itself went smoothly, with no reported errors. The nvidia-current kernel module got properly compiled and installed by dkms, everything looked fine. And glx on my primary display was _not_ broken again by installing nvidia packages, glx-alternatives, etc. However, bumblebee still does not work, so I have no accelerated graphics. If I try e.g. optirun -vv glxinfo, I get: gmulas@capitanata:~$ optirun -vvv glxinfo [54329.188696] [DEBUG]Reading file: /etc/bumblebee/bumblebee.conf [54329.189560] [DEBUG]optirun version 3.2.1 starting...

Please let me know if there is something I can do to provide more info to nail the problem. Also, if you can suggest some way to make at least cuda and opencl work, with or without bumblebee, and with or without graphics acceleration, that would be most useful (I test software on my laptop and now I can't do this with those that need GPU acceleration).
