Celluloid can't open with x11 backend, Gtk-WARNING **: cannot open display:
by TheJooomes from LinuxQuestions.org on (#561J7)
I'm running Fedora Workstation 32 with Gnome. Just out of the blue Celluloid quit working on my main PC which runs Xorg, but continued to work on my other desktop and laptop which use Wayland. When launching Celluloid through the terminal, I got:
Code:$ flatpak run io.github.celluloid_player.Celluloid
(io.github.celluloid_player.Celluloid:2): Gtk-WARNING **: 12:03:48.097: cannot open display:I tried the same thing, but with the GDK_BACKEND=x11 environment variable and got the same error, regardless of which session I'm running. Running Celluloid in a Wayland session with the Wayland backend works as perfectly as it always had before. Interestingly, this issue doesn't exist on my laptop with Intel graphics, but both my desktops with Radeon graphics have the issue. One of the desktops has an RX 560, and the other has an R5 240, both using AMDGPU, while the laptop has HD 3000 iGPU.
There are no bug reports on the github page, so hopefully this is something I can fix...?
