Bug 122140 – glx opengl does not work on amd64

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Igor V. Kovalenko 2006-02-08 08:56:44 UTC]

glx extension opengl does not work on amd64 and probably other 64bit arches, xorg-server use wrong datatypes compiling glcontextmodes.c imported from Mesa. Common sympthoms include client message "libGL warning: 3D driver claims to not support visual 0x23" etc.

This precludes use of glx extension, resulting in no accelerated opengl support.

Upstream patch for Mesa library regarding this issue is now available.

I am seeing the problem here on an i810 running on amd64. Will test the fix when get a chance.


-MESA_PV="6.4.1"
+MESA_PV="6.4.2"

Why are you incrementing the version? Unless upstream releases a new version, generally gentoo releases new package revisions for things like this.

It's what I have here; Mesa 6.4.2 is even installed by gentoo mesa package so I thought that would not hurt. xorg-server ebuild would be bumped anyway I think.

The bump is quite irrelevant in a source code sense, but it'll probably change so people don't need to download both tarballs.

That's my actual intention here. The same is true for mesa-progs package.

Please note that this three-liner patch is somewhat related to security (you can read 4 bytes past server context) and can cause crashes (if those bytes are not in mapped memory)

Fixed in xorg-server-1.0.1-r3, thanks!
