 Posted: Thu Feb 06, 2003 4:21 am Post subject: Unable to find a suitable X Visual |
 |
|
I'm having a problem with a program I just installed called, "Search And Rescue"... it's a game, yeah.. but it uses OpenGL and I've had this problem a couple other times with OpenGL stuff. It's gotten tot he point that I can't use OpenGL programs and that's bad 
When I start up the app (normal command line, /usr/games/SearchAndRescue) it says:
| Code: |
Unable to find a suitable X Visual.
Please verify that you have an X Visual suitable for OpenGL rendering
by running "xdpyinfo". Also note that defining multiple Visuals
may confuse the selection of a proper Visual (in which case try defining
only one Visual.

I've ran xdpyinfo but I'm not sure what to look at in there at all.
here's it's output:

I know it's not Gentoo that's the problem. But, it may well be my OpenGL setup. I've re-ran "opengl-update nvidia" to make sure that wasn't it, nope.. it wasn't. heh...
I'm at a loss... does anyone have any ideas? |

I clutching at straws here...
Someone else had the same problem as you. The only advice he ever got was to run with a smaller resolution.

Sorry, but this was all I could find.

Set 'DefaultDepth' and 'Depth' in /etc/x11/xorg.conf to 24. That solved it for me.
