Thanks Andreas,
I would add that since I did not want to risk upgrading my nvidia drivers from their current pinned version, there was no problem fixing this issue while staying with glx-diversions_0.2.2: 1. I added a local diversion: local diversion of /usr/lib/i386-linux-gnu/libGL.so.1.2.0 to /usr/lib/mesa-diverted/i386-linux-gnu/libGL.so.1.2.0 2. in mesa-diverted, I added a hard link from libGL.so.1.2.0 to libGL.so.1.2 3. and also a symlink from libGL.so.1 -> libGL.so.1.2 With those manual changes, glx-diversions_0.2.2 can be reinstalled without errors and hardware acceleration works again. Maybe the change to libgl1-mesa-glx could have been avoided if the postinstall script added more args to the function: validate_diverted_symlink ... `dpkg --listfiles libgl1-mesa-glx | grep '^/usr/lib' | xargs basename -a` so that however libgl1-mesa-glx chose to version its libGL.so, they would still be found by glx-diversions postinstall. thanks, --jack ________________________________ From: Debian Bug Tracking System <ow...@bugs.debian.org> To: js <jsh...@yahoo.com> Sent: Tuesday, September 10, 2013 8:30 AM Subject: Bug#722258 closed by Andreas Beckmann <a...@debian.org> (Re: Bug#722258: glx-diversions fails libGL.so.1 -> /etc/alternatives) This is an automatic notification regarding your Bug report which was filed against the glx-diversions package: #722258: glx-diversions fails libGL.so.1 -> /etc/alternatives It has been closed by Andreas Beckmann <a...@debian.org>.

Closing. BTW, libgl1-mesa-glx has a fix pending that adds a Breaks: glx-diversions (<< 0.4) so people won't be able to do this broken partial upgrade any more. Andreas Package: glx-diversions Version: 0.2.2 Severity: normal Dear Maintainer, ==================================================================== I updated libgl1-mesa-glx to version 9.1.6-2 (from 8.0.5-3) and saw that afterwards /usr/lib/i386-linux-gnu/libGL.so.1 -> libGL.so.1.2.0 instead of the /etc/alternatives/glx--... that would lead to the nvidia library. Therefore the hardware acceleration was broken. I tried purging all the nvidia files and reinstalling but the problem persists because the glx-alternatives postinst script does a validate_diverted_symlink() and does a "Restoring diverted libGL.so.1 symlink". After reinstalling glx-diversions (many attempts), this left libGL.so.1 pointing to the library from libgl1-mesa-glx. This happened even after I removed all the nvidia packages, manually removed any remaining diversions for '*glx*' so that only libgl1-mesa-glx was left, with no diversions. I would have thought glx-diversions would have left the diversion in place and tried to leave the symlink pointing to /etc/alternatives. Manually setting this link to point to /etc/alternatives/glx--... does restore hardware acceleration but this seems to break whenever another package is installed, so is not a real workaround. I have the nvidia drivers pinned to 306.64-4 and therefore glx-diversions is pinned to 0.2.2 (I understand this is not the latest version).
