RE: Flickering problems on external monitor with HDMI after installing
Ubuntu
Not having a monitors.xml is fine. I was only concerned about the
possibility of monitors.xml containing bad data.
What if you choose 'Ubuntu on Xorg' on the login screen (menu in the
bottom right corner). Does that prevent the bug from occurring?

Thanks. I don't see any errors relevant to this bug, only bug 2034664
(which you should have the fix for already?) and bug 1857392.
Next please try deleting the monitor layout settings:
rm ~/.config/monitors.xml
and then log in again. Does that improve the situation?

Thanks. It was unclear from the first bug which monitor was flickering.
In the first bug it sounded like the laptop. In this second bug it
sounded like the external monitor. Now the video shows it's the laptop
screen.
Is it only the laptop screen flickering?
I'm wondering if this is due to a
I had the same problem when using another HDMI cable
I couldn't change the external monitor to a lower resolution because it
kept flickering and going to the menu for the external monitor, it would
just reset and send me to the settings for the built-in monitor
I attached a video

Thanks for the bug report. Most likely the problem is an HDMI connection
problem. Please try a new HDMI cable if you can. If you can't then
please try temporarily running the external monitor at a lower
resolution to see if the flicker then goes away.
If the flicker still persists then please
