My second monitor is not detected on Ubuntu 24.04, although everything was okay 2-3 days ago.
Sometimes it works for just 5 minutes and then shuts off by itself.
I have tried to reinstall “nvidia-driver-580” from the GUI for drivers afetr purging all nvidia packages and execute this.
$ sudo bash -c “echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf” $ sudo bash -c “echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf” $ sudo update-initramfs -u $ sudo reboot
The external monitor over HDMI does not work (since the HDMI port is wired to NVIDIA). When I select the NVIDIA profile (prime-select nvidia)
Can you help me? @MarkusHoHo
