Up until my most recent apt-get upgrade, I was using bumblebee to manage my nvidia graphics card, and it was working perfectly - using primusrun, I could get upwards of 700 fps with glxgears. Now, however, when I try primusrun glxgears, I get this error:

primus: fatal: Bumblebee daemon reported: error: Could not load GPU driver

So I look in dmesg and see this:

[33359.665924] nvidia: Unknown symbol acpi_os_wait_events_complete (err 0)

By using dpkg, I see that I have these nvidia packages installed:

  • bumblebee-nvidia
  • nvidia-304
  • nvidia-304-updates
  • nvidia-current
  • nvidia-settings

Googling this lead me to this page, which suggests adding a patch to the driver and recompiling it if you have errors on kernel version 3.13 (which I'm on). Where can I find the source code for the driver to recompile it? I thought the nvidia drivers were closed source, but the people on that forum don't seem to be nvidia devs. I'm comfortable compiling packages and with make, but if anyone has advice compiling the driver it would be well appreciated.

Edit: I think I'm having the same problem as this person.

  • You could try asking Nvidia for the source, but they would most certainly refuse to give it to you. Good luck anyway. – mikewhatever Aug 9 '14 at 17:21
  • Then how are other people solving this? Am I missing something? There are definitely other people with this problem, who aren't nvidia devs, who have solved this. – zrneely Aug 9 '14 at 17:32
  • Take a look at my answer here, see if it helps. – Mitch Aug 9 '14 at 18:10
  • Unfortunately, it didn't. What I ended up doing, is since I still had all my version 3.8.0 kernel packages installed, I just uninstalled the 3.13 version. So I'm using an older kernel but now everything works, for now. Hopefully the bug will be fixed soon. – zrneely Aug 9 '14 at 18:46

The file you need to patch is stored in /usr/src/nvidia-??/nv-acpi.c (in my system with nvidia-331 the path is /usr/src/nvidia-331-331.38/nv-acpi.c). The driver per se is closed source but this file belongs to the driver/kernel interaction.

As you have both 304 and 304-updates, make sure you patch the one Bumblebee uses (in doubt patch both).

Then to rebuild kernel modules run

$ sudo dpkg-reconfigure nvidia-304
$ sudo dpkg-reconfigure nvidia-304-updates

As you can guess this is just a temporary fix. If you update any of those packages your changes go away. To avoid that block the update of those packages.

  • Thank you! It seemed like everyone on forums, etc. knew where those files were. I suppose I should have just grepped around for them. – zrneely Aug 10 '14 at 1:55
