Description David Mulder 2024-04-16 14:05:06 UTC 
After a hard reset (laptop locked up when I tried to suspend it), my external monitors are no longer detected. I've seen this happen 3 times in as many weeks (on several recent versions of TW), and the only solution I've found is reinstalling TW.

> sudo hwinfo --monitor
