However, that resolution is woefully low. How is a higher resolution selected?
Previously, rebooting fixed the resolution problem. Now, it's stuck at the "highest" resolution which is far lower than the resolution yesterday.
In the context of generally troubleshooting Wayland, for this given graphics card:
nicholas@mordor:~$
nicholas@mordor:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

How would I determine the resolution it's detecting as available for a given monitor?

(Wasn't sure on the syntax using hwinfo to get more info on the graphics card or above monitor.)
Somewhat random info from a Fedora guide and an online man page, but I'm more interested in how Wayland uses this information.
