The title says it all. A recent update has once again killed fglrx direct rendering from working with Xorg, so I’ve decided to just switch over to the free software Gallium driver entirely. This means no Amnesia, but I’ve since finished that game. It probably goes without saying that CrossFire won’t work now too, so… I would like to say that three of my GPUs are just doing nothing, but there are still power management issues with the radeon driver so the fans are sending my wife and I deaf while my cards cook at around 80-90 degrees, and it heats up my apartment noticeably – an annoyance since we’re heading towards the middle of summer here. It also means no OpenCL support since the AMD APP SDK depends on fglrx, although fortunately I haven’t been using that lately either.

The uninstallation of fglrx did not go smoothly. There have been times since I first performed my current desktop OS install where I manually ran the installer downloaded from AMD’s website, which spread files all over the place. These had to be cleaned up. The following two links were the most useful I came across which deal with this problem:

• http://dri.freedesktop.org/wiki/DriTroubleshooting
• https://wiki.ubuntu.com/X/Troubleshooting/FglrxInteferesWithRadeonDriver

However, the final issue I had was documented on neither of those. The AMD installer created a file on my system in /etc/profile.d/ati-fglrx.sh which set an environment variable which caused direct rendering fail ($LIBGL_DRIVERS_PATH IIRC). Removing that file, logging out and in again got everything back to normal… well, “normal” as described above. :/

I’m still keeping fglrx on my laptop though (which I haven’t updated in a while)… for now. I don’t want my laptop run into the same power management issues leading up to Linux.conf.au 2012.

Here’s something I’ll be taking away from this experience. Proprietary software might sometimes be better than free software, but generally there can be no expectation of it becoming any better in the future than it is today. In the future it may become incompatible, may add new restrictions upon you, may not support new formats, may force you to upgrade (sometimes at cost) to continue functioning properly, etc. The issue I have experienced in this post was the former. With free software however, I can generally expect that the software I have today will never become worse over time – that is, it only gets better. Even in cases where ‘better’ is debatable (eg. GNOME 3), it can be (and often is) forked by anyone. That’s one of the reasons I love it.

To show my support of free software and software freedom, I have finally done something I feel guilty for not doing a long time ago – and became an associate member of the Free Software Foundation.
