 ## Program behavior notes
-This program has to grab all keyboards and create a virtual keyboard (`gsr-ui virtual keyboard`) to make global hotkeys work on all Wayland compositors.

+This program has to grab all keyboards and create a virtual keyboard (`gsr-ui virtual keyboard`) to make global hotkeys work on all Wayland compositors.\
+This might cause issues for you if you use keyboard remapping software. To workaround this you can go into settings and select "Only grab virtual devices".\
+If you use keyboard remapping software such as keyd then make sure to make it ignore "gsr-ui virtual keyboard" (dec0:5eba device id), otherwise your keyboard can get locked
+as gpu screen recorder tries to grab keys and keyd grabs gpu screen recorder, leading to a lock.\
+If you are stuck in such a lock where you cant press and keyboard keys you can press (left) ctrl+shift+alt+esc to close gpu screen recorder and remove it from system startup.

 Add recording timer to see duration of recording/streaming.
 
 Make folder with window name work when using gamescope. Gamescope runs x11 itself so to get the window name inside that we have to connect to the gamescope X11 server (DISPLAY=:1 on x11 and DISPLAY=:2 on wayland, but not always).

+    This seems to only be an issue on wayland? the window title of the gamescope/steam bigpicture mode is the title of the game on x11, so it works automatically on x11.

+Notification with the focused monitor (with CursorTrackerWayland) assumes that the x11 monitor name is the same as the drm monitor name. Same for find_monitor_by_name.

+If CursorTrackerWayland fails then fallback to getting focused monitor by window creation trick. Need to take into consideration prime laptop with dGPU that controls external monitors which cant be captured (different /dev/dri/card device).
+    Maybe automatically switch to recording with the device that controls the monitor.
+    In that case also add all monitors available to capture in the capture list and automatically choose the gpu that controls the monitor.
