I’ve been a Openbox & Xfce user most of my GNU/Linux life. Only recently, I’ve started using KDE Plasma. In Openbox one can easily run a command via its autostart file to set a random wallpaper,

feh --no-fehbg --bg-scale --randomize path/to/the/wallpaper/directory/* &

Xfce makes it even easier as there already is an option to set a random wallpaper at startup in its settings.
In KDE Plasma, I was unable to find any option to set a random wallpaper at the session startup so I came up with a little hack to achieve this.

Problem:

You installed Arch Linux or Manjaro or any other Arch derivative but you didn’t install Grub2 on the MBR of your HDD as you already have Grub2 installed there and you want to control the boot process from already installed Grub2 instance but booting Arch or Manjaro via that Grub2 menu is ending in kernel panic.

Problem:

You have Manjaro with Xfce desktop environment installed and you want to turn numlock on by default so that you can use the number-pad on your keyboard at the login screen and after logging-in to Xfce desktop. This should have been the default behavior but sadly it’s not! Anyway, it’s an easy problem to fix. This solution is written for Manjaro but it should work on almost all Arch Linux based distributions and derivatives with LightDM display manager.

Problem:

You have openSUSE with Xfce desktop environment installed and you want to turn numlock on by default so that you can use the number-pad on your keyboard at the login screen and after logging-in to Xfce desktop. This should have been the default behavior but sadly it’s not! Anyway, it’s an easy problem to fix. This solution is written for openSUSE but it should work on almost all GNU/Linux distributions with Xfce desktop environment and LightDM display manager.
