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)
dpkg, I see that I have these nvidia packages installed:
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.
