Upgrading Fedora Core

There's an article [1] here. I thought I'd bookmark it, for easy reference.

Keyboard problems in Linux with IntelliJ

Numpad arrow keys

So the numpad arrow keys do not work in my IntelliJ editor under Fedora Core 31.

I read about similar issues on the Internet.

One of the solutions that worked for me, was to change the file /usr/share/X11/xkb/symbols/keypad.

First off copying the original file seems like a good idea, something like keypad.original.

Then replace all occurrences of KP_Up, KP_Down, KP_Left, KP_Right with Up, Down, Left, Right respectively.

Either rebooting or executing a setxkbmap should do the trick.

Ctrl-Alt-Left and Ctrl-Alt-Right

I use these to go to the next or previous call in Intellij. Linux just wants to switch Workspaces, when I do that.

The shortcuts could not be found using the standard Settings tool.

But I found a solution at [2].

gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-up []
gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-down []
gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-left []
gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-right []

With a reset if I decide to need it like:

gsettings reset org.gnome.desktop.wm.keybindings switch-to-workspace-up
gsettings reset org.gnome.desktop.wm.keybindings switch-to-workspace-down
gsettings reset org.gnome.desktop.wm.keybindings switch-to-workspace-left
gsettings reset org.gnome.desktop.wm.keybindings switch-to-workspace-right
