Question

I get this wierd error when I’m trying to run (for example) optirun -vv glxspheres. I had it working a couple of days ago, but now it just wont start.

    [DEBUG]Reading file: /etc/bumblebee/bumblebee.conf
    [DEBUG]Process /sbin/modinfo started, PID 8452.
    [DEBUG]Hiding stderr for execution of /sbin/modinfo

    [DEBUG]Socket closed.
    [ERROR]Aborting because fallback start is disabled.
    [DEBUG]Killing all remaining processes.

Some background info:
I’m running a wubi (11.10) install on an ASUS UL30VT. The only thing I really did since the last time optirun was working, was using windows. Previously I changed /etc/bumblebee/xorg.conf.nvidia to allow me to use the HDMI port. But that doesn’t seem to be the problem. I looked everywhere to find someone with a similar error, but with no luck.

The output from lspci | grep -i vga is

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce G210M] (rev a2)

And from sudo cat /proc/acpi/bbswitch is

0000:01:00.0 ON

Here’s my xorg.conf.nvidia:

Answer 1

The error message is quite clear: Xorg can’t find the module void.

The place you’re telling it to load is:

Section "InputDevice"
  Identifier "void-mouse"
  Driver     "void"
EndSection

Either you make xorg find the module or you remove it from xorg.conf.

• To install it on Debian: sudo apt-get install xserver-xorg-input-void. Then you’ll have to guarantee that Xorg is trying to find it in the appropriate place (see ModulePath).

• To remove the module from xorg.conf, try to just remove the section above and then also remove the following line from Section "Server Layout":

  InputDevice "void-mouse"
  

PS: I’m not sure stackoverflow is the right place for this kind of question…
