DetailsOn paxd 32-1 and linux-grsec 4.3.3.201601192226-1
Attempting to use optirun (bumblebee 3.2.1-10) or primusrun (primus 20151110-4) to start a program on the secondary GPU (Nvidia GT 555M, nouveau drivers) fails with the following error: /dev/dri/card1: failed to set DRM interface version 1.4: Permission denied With primusrun, this results in crashing the X server. I tracked the problem down to MPROTECT. Both programs work normally with it disabled on /usr/bin/optirun and /usr/bin/primusrun. Can you please add these settings to paxd? |

Additional comments about closing: User requested: I realized that I had accidentally switched optirun to the nvidia driver. The problem with the nouveau driver is not resolved by disabling mprotect. Sorry for the noise.
