Useless background: I am trying to create a Gentoo workstation to mimic a graphical feature of a CentOS5 box. When I connect to the CentOS5 box using Exceed (a PC X-server), I get a "Xinerma" type behavior, where both of my PC's monitors are recognized and used as two "displays". However, in exporting the Gentoo box's grapics, my 2 monitors are recognized as one huge display. The primary practical difference is how "maximize" works and where forms and splash screens appear. Bottom line: I am trying to mimic the CentOS5 graphical setup, which uses the "nv" driver instead of "nvidia". Problem: I am trying to downgrade from "nvidia" to the "nv" driver. I thought I did so successfully, but in trying to emerge "xorg-x11", I get an error about a missing "-lGL". I checked "eselect opengl", and I get this: # eselect opengl list Available OpenGL implementations: [1] xorg-x11 # eselect opengl show (none) # eselect opengl set 1 Switching to xorg-x11 OpenGL interface...ln: creating symbolic link `./libglx.so': File exists !!! Error: Failed to create lib64/libglx.so Killed I got similar errors for other files also. It appears that the links to the nvidia driver were not removed, and I had to remove them manually, like so: unlink /usr/lib32/libGL.so unlink /usr/lib32/libGLcore.so unlink /usr/lib64/libGL.so unlink /usr/lib64/libGLcore.so This has allowed me to progress a little further in trying to switch to working version of opengl, but I am stuck now. I expected eselect to unlink all the necessary links, even if they point to files that do not exist.

I found the 2 remaining missing links like so: # find / -xdev -ilname "*libglx.so*" -exec ls -latr '{}' \; lrwxrwxrwx 1 root root 45 2008-06-19 13:57 /usr/lib64/xorg/modules/extensions/libglx.so -> /usr/lib64/opengl/nvidia/extensions/libglx.so In the /usr/lib64/xorg/modules/extensions directory, which contained the broken libglx.so link, I found another broken link to an nvidia lib (), which I also deleted. Afterward, eselect opengl ran to completion and so did my previous emerges. I am pass my immediate hurdle, but should not eselect do this work for me (replacing all the links, even if they are broken)? Should I have to delete all the links manually? Thanks!
sorry, the other broken lib was: /usr/lib64/xorg/modules/extensions/libwfb.so -> /usr/lib64/opengl/nvidia/extensions/libwfb.so

Created attachment 179033 [details, diff] Fix opengl.eselect to remove broken symlinks, too The old symlinks aren't deleted, because [[ -e dead_link ]] fails. The check isn't even necessary. 'rm -f' will happily ignore missing files, so just remove it.
Ping. Comments? :)
Sounds like a good approach to me. Hopefully someone will add it to the ebuild.
Fixed in SVN. I'm going to leave this bug open until it hits a release. Thanks for the patch!
"me too" on x86 this time. Manually applied the attached fix. Hoping this is released soon.
1.0.7 added to the main tree with this :]
