+The displaymode entry can have three values for drawing the map:
+  * 0 : Pixmap
+  * 1 : SDL ; command line option [[optional parameters#-sdl]]
+  * 2 : OpenGL ; command line option [[optional parameters#-opengl]]
+Any other numerical values than those above will still be "acknowledged" by the client, but will lead to error messages  as \\
+''[WARNING ] (common::finish_face_cmd) Got error on create_and_rescale_image_from_data, file=HOME/.crossfire/image-cache/la/lava_S.113.base.1'' \\
+and \\
+''[WARNING ] (common::display_newpng) create_and_rescale_image_from_data failed for face 481'' \\
+, thus the map would not be drawn.
+=== SDL ===
+If the SDL libraries were not available at [[client compiling]] time, then the displaymode would fall back to Pixmap mode. \\
+The client then should print to stderr from function //load_defaults()// in //client/gtk-v2/config.c//
+<code c>
+#if !defined(HAVE_SDL)
+    if (want_config[CONFIG_DISPLAYMODE] == CFG_DM_SDL) {
+        want_config[CONFIG_DISPLAYMODE] = CFG_DM_PIXMAP;
+        LOG(LOG_ERROR, "config.c::load_defaults", "Display mode is set to SDL, but client "
+            "is not compiled with SDL support.  Reverting to pixmap mode.");
+    }
+#endif
+</code>
+See also [[#lighting]] modes for SDL.
+=== OpenGL ===
+The OpenGL mode is available on Linux, if the MESA package is found at compilation time. \\
+If the gdefaults2 entry is set to 2, and MESA was not found at compilation time, \\
+<del>the client acts differently than started with the -opengl parameter.</del> \\
+the client prints \\
+''[ ERROR  ] (config.c::load_defaults) Display mode is set to OpenGL, but client is not compiled with OpenGL support.  Reverting to pixmap mode.'' \\
+to the logging output.
+When using OpenGL displaymode, the GLX and probably DRI extensions should be available to the X-Server, \\
+when the X-Server Xorg is started to manage the monitor of the computer. \\
+When the GLX extension is not available for the X-Server, then the client will either crash with \\
+message ''Xlib:  extension "GLX" missing on display ":0.0".'' and ''Segmentation fault'' as for \\
+version 1.10.0 for example; or \\
+printing ''Direct rendering is not available!'' to the loglevel INFO log output as it is for version 1.70.0 of the client, \\
+and still would work in OpenGL drawing mode if  libGL.so.1, libGLU.so.1 and libglut.so.3 are available on the system ( but GLX disabled for the X-Server ) .
+Special kdrive X-Servers disbanded after version 1.4.x of the Xorg R7 release like Xvesa, \\
+likely will not work with MESA and DRI. \\
+The Xorg's own driver vesa_drv.so and probably some special framebuffer drivers will also not work \\
+with OpenGL / MESA.
