I use the (excellent) CopyQ advanced clipboard manager. You can sync it across platforms. Upon a fresh install of the first things I do is install it and sync up my clipboards and tabs.
On this fresh install on Zorin however I browse for my Copyq tabs / clipboards.It's in 'home/myname/documents' and I select it. But then Copyq shows the path 'run/user/1000' has been chosen.
Understand there's another post about 'run/user/1000' on this forum another not very helpful one on Reddit. Neither give any advise on how to choose the appropriate directory.
You can install copyq as .deb package then you need no permissions and it works probably better. When it is installed as Flatpak you should set the permissions with flatseal.
You can install the .deb package with
"sudo apt install copyq"
(first remove the flatpak)
I read that Wayland could cause the problems with copyq. But you are on Zorin lite that uses XOrg (X11) by default, or not? Otherwise if you use Zorin Core with Wayland try to switch to Xorg. Logout and at login click on your profile. Then a cog appears, click there and set "Zorin desktop on Xorg".
Thanks for your reply. Using Core. Switching to Xorg at login, and removing the flatpak and re-installing as a Debian package worked. Hope this helps others.
