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


gives the following error

    Error: couldn't get an RGB, Double-buffered visual


    lspci -k | grep -EA2 'VGA|3D'

I'm not sure if this is the solution you're looking for. I had a lot of problems with my Nvidia video card too and this is what worked for me.

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

This will give you additional open source drivers to choose from. Just open up additional drivers and choose the one your video card needs. My video card needed 367.44

  • Yup, tried it, same error. Error: couldn't get an RGB, Double-buffered visual
