I recently had some problems on sharing the screen on zoom, and I found out that disabling Wayland does the trick. It worked fine for my computer, but when I tried doing this on another computer, I wasn't able to login anymore.

My question is: How can I check if I X11 is installed before disabling Wayland?

Thank you in advance!

To see if you have x11 installed, simply run this command from a terminal:

dpkg -l | grep xserver-xorg-core

and if you get something like:

ii  xserver-xorg-core                      2:1.19.5-0ubuntu2                                          amd64        Xorg X server - core server

then you have the server installed.

Here follows a short addition.

If someone is interested in more X11 related information the following command may help:

sudo Xorg -version

or just

sudo X -version

In my case regarding Kubuntu 22.04 LTS this will give:

X.Org X Server 1.21.1.4
X Protocol Version 11, Revision 0
Current Operating System: Linux test-iMac 5.15.0-87-generic #97-Ubuntu SMP Mon Oct 2 21:09:21 UTC 2023 x86_64
Kernel command line: ro root=UUID=0611c7b6-3d07-4592-b622-d3240df90979 quiet splash vt.handoff=7 initrd=boot\initrd.img
xorg-server 2:21.1.4-2ubuntu1.7~22.04.1 (For technical support please see http://www.ubuntu.com/support) 
Current version of pixman: 0.40.0
        Before reporting problems, check http://wiki.x.org
        to make sure that you have the latest version.
