Graphics Driver Headaches

Nothing like computer problems when you’re trying to wrap up your dissertation to really make your day…

Quick tl;dr version: I’ve had a lot of problems with NVIDIA Linux drivers 337.x and even more with 340.24, at least on dual Quadro K600 cards driving four displays using basemosaic. No such problems under 331, but Debian didn’t package the 331 update that supports the current xorg-server ABI. I took their 331.79 package and updated it with the upstream 331.89 version, which fixes a few bugs, adds two PCI IDs, and adds support for the newer xorg-server ABI. Here are the source package, as well as the build results from my i386 and amd64 jessie cowbuilders. Use at your own risk, but they work great for me so far. You’ll have to pin the versions otherwise it’ll try to upgrade after you install them.

The standard disclaimers (no warranty, not responsible for problems, crashes, nasal demons, etc) apply: use at your own risk.

After the jump: deb packages, source packages, source debdiff, problem description, process, and lessons learned.

Drat – SparkleShare unofficial PPA includes breaking update

The SparkleShare unofficial PPA contains a python-gobject update that breaks a number of things, including software center/update manager, gedit plugins, etc. On the page for this PPA it does now mention that it’s not recommended for Ubuntu Precise 12.04 – but it’s a bit too late for me to avoid issues.

What’s more, ppa-purge ppa:rebuntu16/sparkleshare+unofficial doesn’t seem to work – it tries to remove most of the packages installed on my system. Same result when trying to force versions with Synaptic. Thus, I unfortunately had to write my own little tool, using python-apt. It asks for no confirmation, and the only test is that it worked on my machine. Consider this fair warning. The script is here.

Run the script to apply the changes, then edit your sources.list or sources.list.d to remove this source, sudo apt-get update, and check in Synaptic to make sure you didn’t miss anything (which would now show up in the Status panel under “Installed (local or obsolete)”).

If anybody wants to help make this an improved replacement for ppa-purge, please let me know and I’ll fork it into a real GitHub repo instead of just a Gist.
