In the remmina window
- click on "Toggle dynamic resolution update" to make the remote screen fill all the available space.
- click on "Grab all keyboard events" for alt tabbing
- click on "Toggle fullscreen mode" for fullscreen
To disconnect, click on the "disconnect" icon.
If you are running KDE on the home machine, disable the alt+click mapping .
K Menu -> System Settings -> Window Management -> Window Behavior -> Window Actions -> Inner Window, Titlebar & Frame -> set Alt + Left button to Nothing -> Apply
The problem is that Alt+click is used to move a window in KDE (Alt+<Left mouse button> and drag mouse) and to enable/disable breakpoints in Pycharm. So, when I used remmina to remote into a windows PC, I was not able to enable/disable the break points in pycharm as alt+click is captured by KDE.
