I've already tried to follow literally everything on ask ubuntu and similar websites but still I cannot manage my graphic card:
- If I look under system settings "Graphics", Ubuntu seems unable to recognize any kind of graphic device (not even intel) since it says: "Driver Unknown"
- Under the tab "proprietary drivers" of the software center it is listed only the Broadcom card, but not nvidia.
Still, if I run
lspci| grep VGAthe system returns:
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev a1)so the system knows that the graphic cards are there.
I've already tried (after the installation of the kernel source and headers using -$(uname -r) to avoid problems) to install the bumblebee repositories and then the nvidia drivers, but still if I run:
optirun glxspheresthe system returns:
[ 3740.367448] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver [ 3740.367550] [ERROR]Aborting because fallback start is disabled.
I'm frankly bewildered and frustrated: what can I do or check now?
