Can anyone else reproduce this problem? I have a Fedora Core 4 machine with a Radeon 9600XT graphics card installed using the ati-fglrx-8.14.13.1-0.lvn.5.4 rpm for the graphics drivers and the kernel-smp-2.6.12-1.1390_FC4 rpm for the kernel. The /var/log/Xorg.0.log indicates that direct rendering is enabled through the fglrx kernel module. The gxlears program confirms this with the fps increased from ~160 fps without the fglrx module loaded to ~3000 fps with it being loaded. All the opengl programs I have tried so far seem okay except for a copy of pymol 0.98 which I built with the srpm from... http://apt.bioxray.dk/rhel/el4/i386/SRPMS.xray/pymol-0.98-1.2.el4.mok.src.rpm using the following patches... --- pymol.spec.rhel4 2005-07-17 13:04:21.000000000 -0400 +++ pymol.spec 2005-07-17 13:05:40.000000000 -0400 @@ -7,13 +7,13 @@ Summary: PyMOL Molecular Graphics System Name: pymol Version: 0.98 -Release: 1%{?reltag}%{?repotag} -Copyright: Python +Release: 1fc4 +License: Python Group: Development/Tools URL: http://www.pymol.org Source0: /usr/src/redhat/SOURCES/pymol-0_98-src.tgz -Source1: Rules.linux-redhat-py23 -Source2: pymol.com.linux-rpm-redhat-py23 +Source1: Rules.linux-redhat-py24 +Source2: pymol.com.linux-rpm-redhat-py24 BuildRoot: %{_tmppath}/%{name}-%{version}-buildroot/ BuildRequires: libpng-devel freeglut-devel python-devel Requires: python2 >= 2.2 --- pymol.com.linux-rpm-redhat-py23 2005-05-12 11:14:03.000000000 -0400 +++ pymol.com.linux-rpm-redhat-py24 2005-07-17 13:04:05.000000000 -0400 @@ -5,7 +5,7 @@ # ============================================================== # Set PYMOL_PATH to point at the correct location on your system # -setenv PYMOL_PATH /usr/lib/python2.3/site-packages/pymol +setenv PYMOL_PATH /usr/lib/python2.4/site-packages/pymol # # ============================================================== # (no changes usually required below here) --- pymol.com.linux-rpm-redhat-py23 2005-05-12 11:14:03.000000000 -0400 +++ pymol.com.linux-rpm-redhat-py24 2005-07-17 13:04:05.000000000 -0400 @@ -5,7 +5,7 @@ # ============================================================== # Set PYMOL_PATH to point at the correct location on your system # -setenv PYMOL_PATH /usr/lib/python2.3/site-packages/pymol +setenv PYMOL_PATH /usr/lib/python2.4/site-packages/pymol # # ============================================================== # (no changes usually required below here) [howarth@graphics SOURCES]$ diff -uNr Rules.linux-redhat-py23 Rules.linux-redhat-py24 --- Rules.linux-redhat-py23 2005-07-17 13:03:18.000000000 -0400 +++ Rules.linux-redhat-py24 2005-07-17 13:03:43.000000000 -0400 @@ -6,7 +6,7 @@ # #- Building ---------------------------------------------------------- #--- Tell "make" how to get to PyMOL during build -PYMOL_PATH = /var/tmp/pymol-root/usr/lib/python2.3/site-packages/pymol +PYMOL_PATH = /var/tmp/pymol-root/usr/lib/python2.4/site-packages/pymol #--------------------------------------------------------------------- # #- Dependencies ------------------------------------------------------ @@ -14,10 +14,10 @@ XLIB_DIR = -L/usr/X11R6/lib XINC_DIR = -I/usr/X11R6/include #--- Python -PYTHON_EXE = /usr/bin/python2.3 -PYTHON_LIB = -lpython2.3 -PYTHON_LIB_DIR = -L/usr/lib/python2.3/config -PYTHON_INC_DIR = -I/usr/include/python2.3 +PYTHON_EXE = /usr/bin/python2.4 +PYTHON_LIB = -lpython2.4 +PYTHON_LIB_DIR = -L/usr/lib/python2.4/config +PYTHON_INC_DIR = -I/usr/include/python2.4 #--- Other external dependencies EXT_INC_DIR = EXT_LIB_DIR = The resulting pymol rpm does run but doesn't use the direct rendering.

The author of pymol is baffled at this point as to why the fc4 built pymol isn't accessing the same renderer since they are both using the same OpenGL libs. It would be most helpful if we could get some other folks testing this in case we are seeing some bug in either gcc4 code generation or in the xorg of FC4. Thanks in advance.

The resulting pymol.spec should cleanly build a package.
