How to fix "no screens found"

Post by administrollaattori » Tue Apr 03, 2018 1:16 pm

If getting "no screens found" message when computer boots, the reason can be a wrong GPU driver or the wrong setting. The fix goes like:

1. Log in

2. Check current directory using command

Code: Select all

pwd
3. Check that network is on using command

Code: Select all

nmcli dev status
4. Check that package management is working using command

Code: Select all

sudo apt-get update
5. Check installed graphic card drivers using command

Code: Select all

dpkg --get-selections | grep xserver-xorg-video
6. Remove the video driver you want or remove all video drivers using command

Code: Select all

sudo apt-get purge xserver-xorg-video-*
7. Remove possible /etc/X11/xorg.conf file using command

Code: Select all

sudo rm /etc/X11/xorg.conf
8. Remove ~/.config/monitors.xml file using command

Code: Select all

rm .config/monitors.xml
9. Install a video driver you want, or install all video drivers using command

Code: Select all

sudo apt-get install xserver-xorg
9 b. If wanting to install only one driver (like xserver-xorg-video-vesa), the command is

Code: Select all

sudo apt-get install xserver-xorg-video-vesa
10. Start X (go to the desktop) using command

Code: Select all

startx
10 b. If Xserver is active, you need to start different X like

Code: Select all

startx -- :1
... or

Code: Select all

startx -- :2
... and so on.

I suppose that's one of the ironies of life, doing the wrong thing at the right moment -C.C.
