The goal is to activate dedicated graphic card to play game.
I updated kernel to install nvidia driver.
I can boot the system in recovery mode but no network available in it.
bellow, this is what i see after reboot after installing nvidia driver. and it does not boot further.
if i purge nvidia via recovery mode, everything gets back to normal(boots properly)
i have lenovo yoga with i7 with integrated and dedicated graphic cards. all time before i used integrated card with no problems on default drivers. But i wanted to play a game that requires more GPU power and i want to activate it. GPU is geforce 1050 mobile.
nothing worked and i updated kernel via ubuntu mainline kernel installer as i found somewhere.
seems like nvidia driver changes mounting setting but i'm not sure.
How to install nvidia properly?
