Switching displays breaks functionality (maybe) #104

Closed JpTiger closed 2 years ago

JpTiger commented 2 years ago

I used Lazycast successfully with a widescreen monitor on a Raspberry Pi Zero W. I used the exact same pi and configuration but unplugged the old monitor and plugged in an old 4:3 Dell Ultrasharp. The pi works fine with the display, and I can establish a remote connection with Lazycast, but I just get an Unnamed Window with a black screen upon connecting. The serving computer seems to think all is well, and will allow me theoretically to change resolutions, but Windows defaults to and recommends the resolution of the old monitor. Changing to the correct resolution does not fix the issue. This happens when trying to extend my display from two different Windows machines.

Did you try deleting the file edid.txt located in the directory that you launch lazycast from? This is the file which provides possible configurations that your display supports and it gets generated only if there isn't one already in place, so you may need to delete it after connecting a different display. (:

Makes logical sense but unfortunately doesn't work. Tried closing all.sh, deleting edid.txy and relaunching, but the issue persists.

Odd development, there might be more going on here. I tried renaming the lazycast folder, cloning into a fresh copy of the github repo and compiling again. The issue mostly still persists: that is Unnamed window opens, black, but then nothing else is displayed and everything else seems to think it's working properly. But this time when I go on the windows machine to see what resolution it's detecting, it's detecting the correct one.

FWIW I'm running Raspbian Stretch on a raspberry pi zero w (first gen) having swapped out the default wifi handler for NetworkManager, as instructed here.

I ran all.sh via SSH this time as an experiment, so I got the printout while it's running. Here it is (including when I manually disconnected):

Isolated the issue. It's not the new display, it's that I enabled the full KMS GL Driver for a different piece of software and forgot about it later. Disabling the driver and rebooting solved the issue. Closing this one and will open a new issue if that one hasn't already been reported.
