I have a problem with dual monitor setup on my laptop. Basically additional monitor is not detected when using NVIDIA drivers.With Nouveau selected it is detected but I only see something that I can describe as visual noise + regular working mouse pointer (like I can move the mouse on that screen).
During Ubuntu installation the monitor was displaying everything properly, and there were no issues, however after the installation process, it is not detected anymore. The issue still persists after a second attempt at the installation with Ubuntu image redownloaded.
I tried both 440 and 435 drivers, same result. I also tried multiple different monitors (different manufacturers and resolutions).
I also tried removing any package with nvidia in its name, with autoremove afterwards and redownloaded drivers via Software & Updates, still no luck.
I am absolutely certain that HDMI port, cable and auxiliary monitors work since I’m dual booting and with Windows there are no issues, but as luck would have it I need the second monitor on Ubuntu rather than on Win10.
Here are the specs: HDMI connection, laptop ASUS TUF FX505DT-AL086, Ryzen 5 3550H, Vega 8 + GTX 1650, 16GB RAM, 970 EVO 500GB (Ubuntu), ADATA SU800 (Win10), separate SSDs for OSes, both installed in UEFI mode, default greeter and DE, no packages modifying those have been installed, Windows fast startup is disabled.
Additionally, I have no idea if that’s relevant, when booting Ubuntu without AC brick I sometimes can’t get to greeter screen, like everything freezes and the only way is to reconnect mains power and do a hard reboot.
And here’s the bug report
I’d be very grateful for any help with the issue, cheers!
