I'm a new and satisfied PCem user. But before that, I ran into an issue that made PCem almost unusable.
First of all, I have to clarify, that I'm on Linux (Fedora 32, Gnome 3.36), that I failed to compile PCem myself, so that I used this repository: https://copr.fedorainfracloud.org/coprs/blowry/pcem/.
In the Readme-LINUX.txt, it's written “The menu is a pop-up menu in the Linux port. Right-click on the main window when mouse is not captured”. Yet when I right clicked, nothing happened. I ended up realizing that the problem is that I'm not in an X11 session, but a Wayland session. To work around the problem, I don't have to start an X11 session, instead I use the following bash command.
Code: Select all
