Can you test again with the latest master? I added support for XWayland, which both Firefox and Brave still require AFAIK. On my setup, however, Firefox and Chromium both crash. I'll have to research what is needed for those still. Please chime in if you know.

Until we get Firefox and Brave to work, you can run GNOME Web/Epiphany just fine.

Oops, I deleted my last comment by accident.

I tried with -Dxwayland=true and got the following. The wlroots-git AUR package includes the -Dxwayland=enabled flag.

Can you post your PKGBUILD for Cage?

Hjdskes avatar Hjdskes commented on September 26, 2024

Nevermind, I forgot to push config.h.in. 🤦‍♂️ This should work now.

Unfortunately it did not. My PKGBUILD is linked at the top.

This should be fixed now with latest master.

It builds now. You might want to mention in the README the Xwayland binary is required if building with -Dxwayland=true.

I tried it with GNOME Web and the mouse cursor disappeared when over the window and I couldn't interact with it:

It builds now. You might want to mention in the README the Xwayland binary is required if building with -Dxwayland=true.

Done in 691847c.

I tried it with GNOME Web and the mouse cursor disappeared when over the window and I couldn't interact with it:

How are you launching cage? If I try GDK_BACKEND=x11 ./build/cage epiphany from a TTY, Epiphany spawns using gdk's x11 backend and the mouse cursor stays visible. Are you by any chance using Nvidia? sway/wlroots is known not to work with Nvidia.

I'll open separate issues for Firefox and Chrome/Chromium/Brave.

I was just using cage <application>. I tried with GDK_BACKEND=x11 cage <application>, but it made no difference.

No, I have an AMD APU using radeon / amdgpu.

EDIT: I was talking about running from a terminal in an x11 session, not from TTY. Running from TTY works fine.

I can reproduce the issue here, and found that rootston does not display the same behavior, so I'm likely doing something wrong. I'll look into this.
