After emerging ati-drivers-8.8.25-r3 on a fresh install of Gentoo (xorg was built as a dependancy and not before, kernel is 2.6.10-r5), 3d acceleration did not work. After checking /var/log/Xorg.0.log I saw that it said that the glx module did not exist. I had it working on a previous install of Gentoo (same hardware, different kernel (2.4.28-r6), different hard drive). I compared the xorg logs of the two installations and saw that the fully working system loaded /usr/lib/modules/extensions/libglx.a and that file didn't exist at all on my new installation. I simply copied the file over to the new installation and everything is fine now (however I've only run glxgears so far). I suspect that this is either a problem in the r3 ebuild or at least a conflict with the kernel and the ebuild. I could not test r1 or r2 as these were removed from portage. Just to sum things up. My system works now that I have manually copied libglx.a to my machine. The problem still remains that this file is not create upon running emerge =ati-drivers-8.8.25-r3. Reproducible: Always Steps to Reproduce: 1.ACCPET_KEYWORDS="~x86" emerge =ati-drivers-8.8.25-r3 2.opengl-update ati 3.xdm Actual Results: xdm start and appears to be behaving, however glxgears, and glxinfo give this error: Xlib: extension "GLX" missing on display ":0.0". Xorg.0.log reports something like the following error: (II) LoadModule: "glx" (EE) module "glx" not found (WW) UnloadModule: "glx" Expected Results: glxinfo and glxgears should do their thing and xorg's log should repot the following: (II) LoadModule: "glx" (II) Loading /usr/lib/modules/extensions/libglx.a (II) Module glx: vendor="X.Org Foundation" Portage 2.0.51-r2 (default-linux/x86/2004.3, gcc-3.3.4, glibc-2.3.4.20040808- r1, 2.6.10-gentoo-r6 i686) ================================================================= System uname: 2.6.10-gentoo-r6 i686 AMD Athlon(tm) XP 2800+ Gentoo Base System version 1.4.16 Autoconf: sys-devel/autoconf-2.59-r5 Automake: sys-devel/automake-1.8.5-r1 Binutils: sys-devel/binutils-2.14.90.0.8-r1 Headers: sys-kernel/linux-headers-2.4.21-r1 Libtools: sys-devel/libtool-1.5.2-r5 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O2 -pipe -march=athlon-xp -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/X1 1/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -pipe -march=athlon-xp -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms" GENTOO_MIRRORS="http://gentoo.osuosl.org http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X alsa apm avi berkdb bitmap-fonts cdr crypt cups dvd encode f77 font- server foomaticdb fortran gdbm gif gnome gpm gtk gtk2 imlib ipv6 jpeg kde libg++ libwww mad mikmod motif mpeg ncurses nls oggvorbis opengl oss pam pdflib perl png python qt quicktime readline sdl spell ssl svga tcpd truetype truetype- fonts type1-fonts xml2 xmms xv zlib"
please paste and emerge -vp xorg-x11
I think this problem is actually being caused by opengl-update. Line 253 of /usr/sbin/opengl-update (2.1.0-r1) reads: "for file in ${PREFIX}/opengl/${GL_LOCAL}/extensions/*.{so,a,la}; do". The path expands to "/usr/opengl/ati/extensions" when running "opengl-update ati" - it should be "/usr/lib/opengl/ati/extensions". If I change that line to read "for file in ${PREFIX}/${LIBDIR}/opengl/${GL_LOCAL}/extensions/*.{so,a,la}; do" it recreates the libglx.a symlink in /usr/lib/modules/extensions as it's supposed to.
The problem has been fixed in opengl-update-2.1.1
Closing the bug then
