 Posted: Tue Oct 28, 2008 2:49 pm Post subject: SDL + OpenGL |
 |
|
Hi there,
this might be a lame problem, but I'm getting an error "Unable to set ... mode: X11 driver not configured with OpenGL" when running my programs with SDL+OpenGL. When I was first emerging xorg-x11, I didn't have the option "opengl" included in USE. I added that and tried to 'emerge -N xorg-x11', but doesn't recompile, says "No outdated packages ..."
Now I don't know if it's a problem with xorg.conf (missing an option that allows OpenGL) or I really have to recompile X server with the option "opengl" ... and in that case I don't know how to do that. Thanks for any advice.

Sethiel, try adding opengl to your use flag and emerge -auvND world (D is for deep, this means it will check if something else except xorg-server can use this flag.
Dont forget to reinstall any x11-drivers/ and then restart.
If you have the problem after this, post:
/etc/X11/xorg.conf
/var/log/Xorg.0.log
eselect opengl list
Version from mesa and xorg-server |

Amazingly xorg-server doesn't have opengl support! | Code: | emerge -pv xorg-server
......
[ebuild R ] x11-base/xorg-server-1.4.2 USE="dri hal sdl xorg -3dfx -debug -dmx -ipv6 -kdrive -minimal (-nptl) -xprint" |
But lots of packages do including media-libs/libsdl. My current system uses opengl like this with a 2008.0/desktop profile | Code: | $ equery hasuse opengl

Helped, thanks. I should probably be ashamed

Well, it seems to work fine, but whenever the program exits, it reports Unauthorized memory access. (SIGSEGV). I realized it's not happening only in my programs, but for example mplayer with -vo gl does the same. What does this mean?

I would suggest that you switch to a desktop profile and update your system, like this | Code: | eselect profile list
eselect profile set <number>
emerge -uDNav world
python-updater
perl-cleaner all |
Then your box should run much better  |

OK, first, is that a solution of this problem or something off topic?
Second, why I'd want to do that? What exactly is affected by various profiles? What changes? I don't have the feeling my system is running slowly, not at all. It actually works much better than before, including Win98, WinXP, Ubuntu, Mandrake, Mandriva, Slackware, Fedora.

It is possible that you are missing some use flags required for a consistently running X session, which are provided by a desktop profile. Also updating your system may be sufficient to repair the segfaults you are experiencing. Definitely upgrading to python-2.5 and running python-updater would likely help. |

No, it didn't help. I'm still experiencing Unauthorized memory access when using OpenGL. Any other idea what can cause this?

Your mesa or 3d drivers are messed up. I've seen this once before. I basically had to reinstall the entire X stack and remake any X-related configs. I didn't take notes, so I'm just going on memory. |

I'm using ati drivers. So I have graphic card in make.conf set to "fglrx", I've emerged atidrivers and I have set "eselect opengl set ati". I also used aticonfig on my xorg.conf, which added a few lines and removed a lot of comments, which I don't like very much. I'm still getting SIGSEGV sometimes ... usually during shutting down some graphic application. Like mplayer.
What are possible causes of this problem I didn't check? Please, give me some ideas. I'm a newbie, but now I think I might have some config in kernel turned on that should be off or vice versa, or it's notebook-based problem and I have to use something different for my ATI Mobility.

Don't know if it's rellevant, but glxinfo says I do have direct rendering and glxgears gives the number of ~900 FPS without crashing down with SIGSEGV.
