Found the source of SegFaults on AMD + FreeGLUT

So the source of the segfaults that I'm seeing on fglrx and FreeGLUT on Kubuntu 14.04 has come to light. It's a known issue with the registration of FreeGLUT and fglrx at-exit handers (at the C level). You can work around it in your own code with PyOpenGL 3.1.0b3+ (which ...

Ubuntu Configuration for Inspiron 15r Running Hot

So you have a Dell Ubuntu 14.04 Laptop and it is running way too hot. You can configure it to run at a reasonable level using i8kmon. As with anything heat related, be careful. If you miss-configure the machine you are likely to wind up with a fried machine!

You create a file called ...

FGLRX fail again, now on 12.04

So I've pretty much given up on the laptop having fglrx running properly, current Ubuntu just doesn't get fglrx, sucks, but okay, I should have stayed on LTS if I wanted a working machine.  But now LTS Kubuntu fglrx is hosed after some system update.  Every attempt to run any OpenGL program just ...

Is fglrx dead for Ubuntu-current

So the AMD Proprietary driver (fglrx) for Linux supports "Ubuntu 12.04 and 13.04" (Note: not the current Ubuntu 13.10), and so far every attempt I've made to use them on 13.10 has supported the "not supported" hypothesis (kernel module compilation failures in the latest iteration).  But drat-it-all my machine meets ...

Voice Dictation Privilege

Apparently I'm blessed with a Voice Dictation friendly accent and tone. I can pretty much use most Voice Dictation systems, including the ones on Android, Dragon Naturally Speaking, and PocketSphinx. The results aren't mind-blowing-ly good, but if it's quiet and I speak clearly and train anything that gets missed, I get reasonable ...

Nexus 5 Phone Contacts WTF

I needed to phone my mother at one point this weekend.

Pulled up the Nexus phone dialer for one of the first times (I don't actually use my phone as a phone all that much). Said my mother's (full) name, saw a brief flash of her details, and they were promptly replaced with ...

Integrated Graphics Really Does Suck

So apparently I forgot to re-install the fglrx driver after updating my laptop to Kubuntu 13.10.  So as I've been testing PyOpenGL I've been amazed by how cr*ppy the GL performance has been, and I kept running into "this doesn't work at all" bugs for newer features. It did make ...

Updating the Laptop to Kubuntu 13.10

Apparently Kubuntu 13.10's version of the fglrx driver is now equivalent to the beta one I added to my 13.04 install to get it running, so I decided to do the upgrade. However, it kept failing with a cryptic error that it couldn't do the upgrade because I was either running ...

Laptop Presentation Fail Take 2

So yesterday we needed to have the participants at the PyCon/Mozilla Maker Party view their videos on the front projector, and the loaner laptops were not happy with the task (many of the projects had 2, sometimes 3 Youtube videos running at the same time in their mashups), so we plugged in my Laptop ...
