I just noticed something strange on startup, before I saw that the recent update of my openSUSE Linux silently switched me to Wayland.
-video opengl is working
With -video bgfx -videodriver x11, the gameinfo screen stays displayed; the emulated screen is not rendered, although the emulation is running (reacts to keypresses).
With -video bgfx -videodriver wayland, I'm getting a segfault:
BGFX: Unsupported SDL window manager type 6 Setting BGFX platform data failed BGFX library initialization failed Segmentation fault (core dumped)
Found on three different installations, for MAME 0.261 and 0.263.

1. Run MAME with -bgfx_debug, pickup a snapshot of that. 2. Run MAME with -verbose flag and paste the output here.

Wayland in general is extremely experimental both from the SDL2 and bgfx ends. If you can force an X11 session, I highly recommend it.

Actually, I don't really feel like going to Wayland; there are still lots of open issues. The desktop login still allows you to select "Plasma (X11)". I just want to make sure I don't blame it for something on our side. There are lots of Wayland advocates out there who give you downvotes in every forum should you dare to express anything less than enthusiasm for Wayland.  ![[Linked Image from mizapf.eu]](http://www.mizapf.eu/files/mame/WaylandIssue.png) -verbose: $ ./mame ti99_4ae -window -verbose Attempting load of mame.ini Parsing mame.ini Loading translation file language/English/strings.mo Reading translation file: 1 strings, original table at word offset 7, translated table at word offset 9 Loaded 0 translated string from file Starting plugin data...

don't know if it makes any difference, but I've noticed that -bgfx defaults to vulkan (at least for me on ubuntu) you could try experimenting with -bgfx_backend opengl

support will probably depend on how complete the wayland compositor is openSUSE chose to go with. I am not running into unexpected issues with wayland (kwin) on debian12. With -video bgfx -videodriver x11, the gameinfo screen stays displayed; the emulated screen is not rendered, although the emulation is running (reacts to keypresses). the xwayland xserver will need to be configured and running for the x11 driver to be supported on wayland With -video bgfx -videodriver wayland, I'm getting a segfault:
BGFX: Unsupported SDL window manager type 6 Setting BGFX platform data failed BGFX library initialization failed Segmentation fault (core dumped) This will happen when the MAME build is not compiled with USE_WAYLAND=1, wayland support is not the default.

FWIW, on fedora both of these work: $ mame -intscaley 3 -autostretchxy -videodriver x11 -video bgfx -bgfx_backend vulkan mvsc
$ mame -intscaley 3 -autostretchxy -videodriver wayland -video bgfx -bgfx_backend vulkan mvsc I am on a different GPU (RADV RENOIR) though.

OK, I added USE_WAYLAND=1, but I'm having some problems when compiling. Seems as if the /usr/include/wayland directory is not in the include search path, as the files that were reported as missing are actually in that directory. I'll check a bit further.

Sounds like maybe it needs to use pkgconfig or whatever to locate the Wayland includes?

The only additional header needed by wayland is wayland-egl.h AFAIR: https://github.com/mamedev/mame/pull/11451/filesWhere is it located on your distro? On Fedora it is directly in /usr/include. If this is not a standard location, we need pkg-config indeed.
