I'm having the similar issue on my 20.04 lts desktop. I'm connecting my second Screen (Samsung Syncmaster SBS 23b300) via standard vga cable.
Whether my primary laptop screen empty or not, When I open control panel, it opens at the second screen regardless it opened or not.(I don't use second screen too much). As a temporary fix, I am using Super+Shift+Left/Right/Up/Down (It depends on your secondary primary screen orientation. In my case, my laptop screen resides on left and secondary monitor resides on right.) keys to move the control panel to the main display. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1888098 Title: Ubuntu 20.04 gnome-shell places windows on second screen when started from primary screen To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1888098/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
