Today I mounted a new grapic card at work, and I wanted to test which resolution fits best for my single monitor. Unfortunately I forgot to set a proper update-rate for the monitor. I pressed "accept", resulting in a black screen, and no possibility to switch back to a valid configuration via GUI. I went to trial & error mode, removed ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml by chance and rebootet the system .. that helped .. phew. ... something a newbe would not be able to do. Thats why I would rate that bug "critical". Actually I would expect the fallback timer to couver such a use case, so that I dont need to do console magic. If you agree that we should have the fallback time as well on "accept" ( Thats the correct translation? It's "übernehmen" in german), than I would provide a patch.
Apparently, this was implemented long time ago, but somehow the code got lost? Bug 867
Possible .. for switching monitors on/off, the timer still exists. So I assume that at some point someone forgot to keep it as well for the "accept" button. Thanks for digging up that patch !
Created attachment 9601 patch to bring the feature back Actually the "fallback" which is currently done via "toggle on/off" just corrupts the current monitor config. So I fixed it for "apply" and "toggle on/off"
