Yesterday I was very disappointed with the Zorin 18 beta. I opened the update application, and it indicated that there were many updates that needed to be performed. I updated and received a message to restart the system. To my frustration, after the restart, the taskbar I had configured at the top simply disappeared. I pressed Super and went to Zorin Appearance, I tried to reconfigure it, but it didn't appear at all.
I asked Gemina for help, and he suggested using the following:
Press Alt+F2 and type r in the box that appeared. The taskbar then appeared.
Afterwards, I realized that to switch the pointer between monitors, I had to move it in the opposite direction from before. For example, I moved it from the external monitor to the laptop monitor by moving it in the left direction, and it stayed on the right. I went to the screen configuration and changed the logical position of the monitors, changing the positions of 1 and 2. After that, the third bar disappeared and no longer appears.
In short, the update broke the system.
I'll close this thread since it's already being addressed here:
