    GLX not loaded automatically ?

    Hi,

    I am unable to use k3d or blender due to a weird graphics related problem. It says glx is not loaded. I tried to put Load "glx" line in my xorg.conf but no success
    Even glxinfo and glxgears complain for the extension glx
    a@pc1:/etc/X11$ glxinfo
    name of display: :0.0
    Xlib: extension "GLX" missing on display ":0.0".
    Xlib: extension "GLX" missing on display ":0.0".
    Xlib: extension "GLX" missing on display ":0.0".
    Xlib: extension "GLX" missing on display ":0.0".
    Xlib: extension "GLX" missing on display ":0.0".
    Error: couldn't find RGB GLX visual or fbconfig

    Xlib: extension "GLX" missing on display ":0.0".
    Xlib: extension "GLX" missing on display ":0.0".
    My xorg.conf is :
    Code:
    Section "Device"
            Identifier      "Configured Video Device"
    EndSection
    
    Section "Monitor"
            Identifier      "Configured Monitor"
    EndSection
    
    Section "Screen"
            Identifier      "Default Screen"
            Monitor         "Configured Monitor"
            Device          "Configured Video Device"
    EndSection
    
    Section "ServerFlags"
        Option "DontZap" "False"
    EndSection
    
    Section "Module"
        Load        "glx"
    EndSection

    Re: GLX not loaded automatically ?

    It may be your graphics card doesn't support GLX, or you aren't using a driver for your card that supports GLX.

    To know which, we'll need to know what your card/chipset is.

    If you don't know, running this command and posting the output here would be helpful:

    Code:
    lspci |grep -i vga

    I think I have NVidia Card. here is the output of the command you suggested.

    Code:
    a@pc1:/etc/X11$ lspci |grep -i vga
    01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 MX 420] (rev a3)

    Yes, and a fairly old one at that. I have similar models in my computers at home, and I'm not sure I could get compositing in KDE working on them.

    Run the hardware drivers tool and make sure you're running the proprietary driver. Compositing may or may not work with the proprietary driver, but it most certainly won't work with the default FOSS driver.

    Re: GLX not loaded automatically ?

    Hi,

    I have pretty much the same problem. I am trying to install freewrl-1.22.5 on a sony vaio with ubuntu 9.10.
    In my /etc/X11/xorg.conf it says driver 'vesa'.
    The output from the command discussed above is:

    Code:
     david@david-laptop:~$ lspci |grep -i vga
    01:00.0 VGA compatible controller: nVidia Corporation Device 0a75 (rev a2)
    I think the software is installed correctly, but when I try to open one of the files with it I get the error

    Code:
    Xlib:  extension "GLX" missing on display ":0.0".
    Xlib:  extension "GLX" missing on display ":0.0".
    Xlib:  extension "GLX" missing on display ":0.0".
    Xlib:  extension "GLX" missing on display ":0.0".
    Xlib:  extension "GLX" missing on display ":0.0".
    FreeWRL can not find an appropriate visual from GLX
    Coud you offer some more detail on how to :
    Run the hardware drivers tool and make sure you're running the proprietary driver. Compositing may or may not work with the proprietary driver, but it most certainly won't work with the default FOSS driver.
    or any other advice.

    Thanks in advance!

    The tool you need is called jockey-kde or jockey-gtk
    In adept, search for jockey and you should be able to find it.
    Install and run it to enable/disable drivers.

    Cheers,

    I have just noticed this is a Kubuntu thread, where as I am runnung Ubuntu.

    Would your advice still be the same?

    I just checked my synaptic and jockey-gtk is installed. As is jockey-common and fglrx-modliases.


    Are there any further suggestions ?

    I have never used ubuntu. But try running
    Code:
    sudo jockey-gtk
    I am quite optimistic it will let you enable proprietary drivers if they are installed.

    This has brought up the hardware drivers menu ( I am sure you knew it would do that.)

    i tried activating them in an earlier attempt.
    I selected NVIDIA accelerated graphics driver (version 185) recommended
    and clicked activate.

    However when I then reboot, my desktop and graphical interface etc will not start up. The boot process does not go past the ubuntu logo.

    I then have to go into recovery mode and replace /etc/X11/xorg.conf with xorg.conf.failsafe to get out of this again.
