How to run a GUI application as a different user?

How to run a GUI application as a different user:

Suppose you are logged into your Linux box as user1 using some X window system already (with GNOME/Unity/..). Now you want to run some gui app as another user, user2.

Run:

  1. xhost + - Run as the user1. This enables access to user1's X window system from other users. You should see following output: 'access control disabled, clients can connect from any host'
  2. sudo su - user2 - Using your favorite terminal, log-in to second user.
  3. export DISPLAY=:0.0 - optional for some apps.

Keychron keyboards on Linux + Bluetooth fixes

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.
