Bug#1037047: cytadela: fails to start under Xwayland: SDL_SetVideoMode(640, 480, 3D): Couldn't find matching GLX visual

[Simon McVittie]

Package: cytadela
Version: 1.1.0-4
Severity: important
User: pkg-gnome-maintainers at lists.alioth.debian.org
Usertags: wayland

cytadela has behaviour very similar to https://bugs.debian.org/1037045
in blobandconquer.

To reproduce:

* GNOME 43 in its default Wayland mode, with Xwayland available
* either of:
    * "classic" SDL 1.2 (libsdl1.2debian version 1.2.15+dfsg2-8 tested)
    * sdl12-compat (libsdl1.2-compat-shim version 1.2.64 tested)
* run blobAndConquer

Expected result: gameplay

Actual result:

> Welcome to the Citadel!
> 
> ------------------------------------------------------------
> Reading the OpenGL vrsion and extensions...
> !SDL_SetVideoMode(640, 480, 3D): Couldn't find matching GLX visual
> 
> Error: Could not initialize OpenGL!
> Exiting...

Workaround (1): log out, and log in to "GNOME on Xorg" instead.

Workaround (2): install libsdl1.2-compat-shim *and* run with
SDL_VIDEODRIVER=wayland,x11 in the environment (which is not the default,
even with SDL 2, because it can cause regressions in other games)
