Where is this ghost output xrandr can't find?

cn flag

I'm running Ubuntu 20.04. At some point there was an issue with the graphics driver and I ended up using xrandr to add an output manually...

There is no longer an issue with the graphics driver but now Ubuntu whines continually that

xrandr: cannot find output "DP-1-1"

I've manually removed the "DP-1-1" entry in ~/.config/monitors.xml to no avail.

There are a number of other files floating around on various sites that can contain the settings but none of these files seem to exist on my system.

I did try using the xrandr command a number of times to remove this output but xrandr can never find it, thus why I'm poking around in the config files.

Here is the full message I receive when I execute bash -l in my terminal:

X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 16 (RRCreateMode)
Serial number of failed request: 32
Current serial number in output stream: 32
xrandr: cannot find output "DP-1-1"

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
