Bug Description

Using nvidia-glx-legacy 1.0.7184+2.6.22.2-7.2 on Gutsy.

[Update]

The nvidia-glx-legacy driver conflicts with composite.

[Workaround] Manually disable composite in your /etc/X11/xorg.conf file:

 Section "Extensions"
        Option "Composite" "Disable"
 EndSection

[Todo for fix]

Modify the nvidia setup script (nvidia-glx-config?) to add the above option to xorg.conf on installation.

Try these two options:

Section "Device"

Section "Extensions"

Also try (independently or (probably) in combination with the above):

Section "Module"

    Disable "dri"
    Disable "GLcore"
EndSection

Adding those options to xorg.conf did not prevent glxinfo from segfault.

Disabling dri and GLcore also did not work.

Evan:
Does _disabling_ composite help?

See https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia#head-6a16bd77ea4c381bf0c6502489d408f9dc6d5d67 for details...

Sitsofe appears to be correct here. In the X log, this error is present:

 (EE) GLX is not supported with the Composite extension

According to the link Sitsofe posted, disabling composite should solve this.

Evan, if you could please verify this works around the issue for you?

If nvidia legacy doesn't support Composite, that's a shame but unfortunately beyond our control since it's a binary driver no longer supported by nvidia. In any case, we should detect and set the composite option properly. I'll update the bug description accordingly.

Bryce:
I don't think using a GeForce4 460 Go with the71xx nvidia-glx-legacy driver is supported by NVIDIA (in theory it should be usable with the 96xx nvidia-glx drivers)...

I believe restricted-manager has added AllowGLXWithComposite to xorg.conf for nvidia-legacy since at least 0.13 (see bug #91064 ).

Evan:
Do you still see this problem on clean installs of Ubuntu 8.04 (Hardy) or later?
