 In the tigervnc-viewer, first open the options and set the compression to 'auto'. In the security options, allow Encryption:None if it is not ticked already.
 Afterwards, you can enter '**localhost**' in the connection dialog and hit Connect if you're on Ubuntu 20.04.
-For 24.04, please enter '**localhost:2**'.
+For 24.04, please enter '**localhost:1**'.
 Please note: Please __do not__ enter the IP address of your remote machine here, but really 'localhost'. This works, because we have a SSH tunnel running (see above).
 **Important: Once after every reboot, a user must log in to the server on site, because the virtual display is only launched after the first user's login.** This is similar to the 18.04 method mentioned above.
+====Errors related to the display====
+Depending on your system, using display :1 might not work. You can try to use :2 instead. In order to do that:
+  * Change the both ports in the ssh commands to 5900+DISPLAYNUMBER. Example: for display :2, both ports should be 5902. for display :1, both parts should be 5901.
+  * Change the -display parameter at the end of the ssh command.
