Driver manager says no proprietary drivers.
I could only change brightness from power management, and then I tried to install Bumblebee but now I can’t change it even there, and my computer shows intel for 2d driver and for 3d says unknown classic 9.2.1 :@
[color=#000080][i]You tried lowering drivers from NVidia page.
For the hardware your computer uses this application:[/i][/color]
[size=medium]sudo add-apt-repository ppa:i-nex-development-team/stable
sudo add-apt-repository ppa:nemh/gambas3
sudo apt-get update
sudo apt-get install i-nex[/size]
Tried, but didn’t changed anything…
[color=#000080]Not to change anything. The above application is used to detect the hardware installed and already know what type of motherboard, video, processor, disk, etc…, Then looking at the manufacturer’s website drivers you need and if they are supported by the distribution.[/color]
Ok, got it, thanks
