One monitor was plugged into HDMI and other one into USB C socket, the laptop has two USB C sockets, one can be used both for charging and display, other one only for data.Įverything was working fine but, both of monitors were detected but after some updates, after I did some updates(apt get update and upgrade) from 20.04 to 20.04.1 and 20.04.02, one day it suddenly is not detecting the one monitor plugged into USB C socket, its not even working after unplugging and plugging it back in(before it would work if I unplug and plug it back). I was using the two external monitors plugged into ThinkPad that has installed only Ubuntu 20.04, the laptop has AMD Ryzen u with AMD integrated graphics.

Sudo apt-get install nvidia-319 nvidia-settings-319 nvidia-primeģ: I dont have sure if you need both (prime and bumblebee) but my geforce 540m could not be selected without install both. Sudo apt-get install bumblebee bumblebee-nvidia
Install Bumblebee using the proprietary nvidia driver: Sudo add-apt-repository ppa:ubuntu-x-swat/x-updates It may be optional for the GT 4xxM and GT 5xxM series on 12.04. As of 12.04, this is still necessary for Nvidia GT 6xxM cards. Sudo add-apt-repository ppa:bumblebee/stableįor more up-to-date nvidia drivers, you need to add another PPA. Then install bumblebee using below commands: Sudo apt-get install linux-headers-generic įirst remove current Nvidia installation.

Does anyone know how to revert the installation of the driver, so I can at least access my ubuntu again? The sidebar won't show up, right clicking doesn't open a context menu and pressing ctrl alt 1 will only give me a black screen. Once I log in I am presented with the standard wallpaper and am able to move the mouse, but nothing else.
ĮDIT: Installing the nVidia proprietary driver completely ****ed my system up. Thanks for any advice, expression of condolence.
So I installed Trusty Tahr two days ago and found that only the screen connected through the DVI-port of my graphics card worked. After a two year hiatus from Ubuntu (and Linux in general), I finally decided to try Ubuntu out once again.
