Bug#886405: bumblebee-nvidia: optirun/primus seems to work, but no display output

[Brainslug]

Package: bumblebee-nvidia
Version: 3.2.1-17
Severity: normal

Dear Maintainer,

I am trying to get optirun/primusrun to work on a Dell Precision M4800
laptop which has Optimus capabilities and the following hardware:

brainslug at m4800:~$ lspci
...
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core
Processor Integrated Graphics Controller (rev 06)
...
01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro
K1100M] (rev ff)


I've installed bumblebee-nvidia and primus packages 3.2.1-17, running
kernel 4.14.0-2-amd64, no multi-arch, Debian testing. No external
displays connected, only internal laptop display used.


optirun/primusrun seems to work for some programs, like darktable &
bash, but for most programs I don't get any display output, examples
include firefox, glxgears, glxinfo.


According to syslog the Nvidia card gets activated and I can see that
/proc/acpi/bbswitch changes from "OFF" to "ON" during
a primusrun/optirun attempt. I just don't see the program output.


Some debug info below - if this bug report should be filed against
another package, please let me know. Any help would be much appreciated.


Initial state:

brainslug at m4800:~$ cat /proc/acpi/bbswitch
0000:01:00.0 OFF

then

brainslug at m4800:~$ optirun -v glxinfo
[  552.198375] [INFO]Response: Yes. X is active.

[  552.198392] [INFO]Running application using primus.
^C[  605.131876] [WARN]Received Interrupt signal.

while running, this in other shell:

brainslug at m4800:~$ cat /proc/acpi/bbswitch
0000:01:00.0 ON

Then after the command is terminated via Ctrl-C:

brainslug at m4800:~$ cat /proc/acpi/bbswitch
0000:01:00.0 OFF

from syslog:

I've also tried to specify the display explicitly, like so:

brainslug at m4800:~$ optirun -v -d :0 -b primus glxinfo

but the results are the same -- no glxinfo output.
