I have a dell l502x laptop with the infamously screwed up hybrid graphics card system (NVIDIA GT540m and Integrated Intel GC)
I have a freshly installed ubuntustudio 16.4.01 LTS running dual boot with windows 10; After installing the proprietary, tested NVIDIA driver 361- recommended at the 'Additional Drivers' tab, a reboot gives a blank screen with the mouse stuck at the top right corner, and nothing works but a forced reboot via long-pressing the main power button.
I have tried all the different driver versions and all the different PPA repositories (xorg-edgers, graphics-drivers etc), the same issue persists.
The system however reboots successfully if the 'intel' card is selected by the command
sudo prime-select intel
when the NVIDIA card is selected
glxgears
gives the following error
Code:
Error: couldn't get an RGB, Double-buffered visual
command
Code:
lspci -k | grep -EA2 'VGA|3D'
gives

I have tried bumblebee as well, but it also gives the same error, when a program is run through the optirun command
