Hello,

After updating my system today (upgraded to nvidia-drivers-346.35), I've noticed that I get this message, whenever I turn the discrete graphics card ON:

Code:
optirun kdevelop
[ 1233.339034] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied

[ 1233.339091] [ERROR]Aborting because fallback start is disabled


Here's my bumblebee.conf file https://bpaste.net/show/12b1f1a7992d

I've reverted to nvidia-drivers-343.36 for now, I wanted to know if anyone else is experiencing this

Update:

dmesg showed this

Code:
NVRM: API mismatch: the client has the version 343.36, but
NVRM: this kernel module has the version 346.35.  Please
NVRM: make sure that this kernel module and all NVIDIA driver
NVRM: components have the same version.


So I rebuilt the modules and everything is okay now!
