After adding export LIBGL_ALWAYS_INDIRECT=1 to $home/.bashrc glxgears works fine, but not Gem. Still the same. ?!
glxinfo gives me a lot of output, and the table seems to indicate better-than the values you gave below, e.g. Vis Vis Visual Trans buff lev render DB ste r g b a aux dep ste accum buffers MS MS ID Depth Type parent size el type reo sz sz sz sz buf th ncl r g b a num bufs ---------------------------------------------------------------------------------------------------- 0x23 0 TrueColor 0 32 0 rgba 1 0 8 8 8 8 0 24 8 16 16 16 16 0 0 I can't find GLX_DOUBLEBUFFER Could it be that I need to add some lines to xorg.conf (wherever it is in Lucid Ubuntu) >On 2012-10-01 11:08, Ed Kelly wrote: >> ...when I try to create a Gem window.

Hmmm... glxgears gives me this: Error: couldn't get an RGB, Double-buffered visual I tried to find a way of adjusting this in the graphics card application, but no luck... e >>>>>if so, what is your pixel-depth? Gem wants to create a 24bit buffer, so if you are running your X in 8bit/palette mode it will bail out. this is what Gem requests: { GLX_RED_SIZE>=4, GLX_GREEN_SIZE>=4, GLX_BLUE_SIZE>=4, GLX_DEPTH_SIZE>=16, GLX_STENCIL_SIZE>=8, GLX_ACCUM_RED_SIZE>=8, GLX_ACCUM_GREEN_SIZE>=8, GLX_ACCUM_BLUE_SIZE>=8, GLX_DOUBLEBUFFER } check the output of glxinfo, whether your config supports such a setting. fgmasdr IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlBpZRkACgkQkX2Xpv6ydvR5VgCgng37YHFrRQoZJk+CMDFz1OGZ fp4AoNrTWuQGqvAg8OgJ2XimzEa9KamQ =gGaA -----END PGP SIGNATURE----- _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
