External monitor does not work on older laptop on Mint 19.3

Post by sudo_lindenberg »

I recently upgraded from Mint 18 to 19.3. After upgrading, I can no longer extend my display to an external monitor via an HDMI cable. This previously worked fine. Now, when I plug in the HDMI cable, the monitor is a blank black screen and my laptop display looks like this:

I thought about switching display drivers, but none show up in the Driver Manager.

My system details are as follows:

Use this command in the Terminal to remove the monitors.xml file, if it exists: rm ~/.config/monitors.xml

Log out and back in. A new file will be created if you make a change in the Display program.

If that doesn’t help, then run a live session using the Mint 19.3 installation USB to check if the same problem exists.

Also, why did you add the Oibaf PPA for your older hardware?

Thanks for your suggestion about checking to see if the problem exists booting from a USB. It does not. So I think I'll just completely reinstall mint. It's been on this drive through several distro upgrades over many years, so I'm sure I've messed something up at some point. Going to start over from scratch.

Regarding your question about that driver PPA - I saw it in some other threads about video driver issues and thought I'd try it as a long shot. It didn't work, obviously.
