10/6/2023 0 Comments Ubuntu system monitor not startingI hope this will solve your problem as it did with mine. Then just reboot your computer and it should boot with no problems (and a different login screen). Now, to uninstall gdm3 (optional), use this command: sudo apt purge gdm3 -y It will ask you which DM you want to use. Sudo apt install lightdm -y # to install it To install LightDM you just have to use these commands in your terminal: sudo apt purge lightdm -y # to make sure that is not installed yet If you, however, prefer some other display manager, I think it will work fine as well. In order to make my computer start properly, I decided to bypass the problem by changing my display manager, so I installed LightDM ( lightdm package). Ps: It is completely normal that the second monitor is not detected in power saving mode when the connection is part of the nvidia graphics card.I was having the same problem and I too was not satisfied by the fsck and the nomodeset solution found on the internet.Īfter days searching for the problem, I have found out that it was not in Ubuntu itself, but was in GDM (GNOME Display Manager- gdm3 package) that, for some reason still unknown to me, was entering into an infinite loop. Hope this also helps you and many others! # This file was generated by nvidia-prime sudo nano /lib/modprobe.d/nfĪnd comment out the the nvidia-drm modeset option. Open the file in your favorite editor (vim, nano, gedit, etc.). It will not be reset, because prime-select only writes this file when it does not yet exists. You can simply undo the change made by prime-select by commenting out this option. It enables the nvidia-drm modeset option. I discovered that prime-select writes a configuration file which causes the problem. At first the external monitor worked perfectly, but after I switched from power saving mode ( sudo prime-select intel) back to performance mode ( sudo prime-select nvidia), the second monitor was not detected anymore. I recently installed the nvidia-418 driver on my laptop which uses Ubuntu 18.04. I got it working thanks to this mans hint at askubuntu forum: I booted from a live ubuntu usb stick and without external montior it worked normally but with external monitor I got the following error message:Īny ideas how to get the monitor working?
