Trying out raw Debian on an old Laptop

So I was given an old Celeron M laptop (XP era, 500MB RAM) and decided to try Debian Stretch out on it. The default Debian netinst installer does NOT include proprietary wireless firmware packages... seriously? Practicality needs to beat purity there. The machine can't boot from USB, and my very last CD-R was used ...

Prime Nvidia can't find GLX (solved)

So the laptop (XPS 15 Kubuntu 18.04) has an nvidia 900 series mobile GPU. When I went to run the unit tests for PyOpenGL... almost entirely red. Because the X display had no GLX extension. To be clear, X was running, KDE Plasma (which normally uses GLX for rendering) was apparently using XRender silently ...

Docker on Centos7 host underwhelms

So one of the things I've been working on recently is creating a docker-based container to host a complex application for video processing that requires a lot of OS-level setup. I, of course, work on a number of Ubuntu 17.04 machines for development, and docker there has proven to be exactly what you ...

GStreamer Playback Captured mpeg.ts using Timestamps

The use case here is capturing a network input source (mpeg ts stream) and then using that capture for playback later. If you just use a filesrc your playback will run as fast as the machine can process it unless you've got an element in the pipeline that will limit the speed (such as ...

Dell XPS 15 (9550) Exploding Battery

So I guess it's necessary that I write this up, as my previous reviews of this laptop were relatively positive, despite the PITA-ish ness of using it with Linux and the coil-whine of the power supply, and the latest issue makes it a "stay the hell away" recommendation.

Background:

A few months ago my ...

Review: Dell XPS 15 (9550) as a Linux Developer's Laptop

Update: the battery in this machine started swelling/exploding at 1.25 years Strongly recommend not buying one!

So I've now had a Dell XPS 15 9550 as my primary driver for approximately 9 months. I covered the (painful) setup process a bit when I first got it, so I won't repeat most ...

Black Screen on KDE after disconnecting external monitor

So yesterday I tried connecting an external monitor to my nVidia proprietary driver KDE laptop. It went meh, as the external display is so much lower resolution (and so much larger) than the configurations on the laptop make the monitor look like a VGA blown up to ridiculous proportions. Oh well, unplugged the monitor this ...

nVidia, package cudnn for Ubuntu already

It's half-way through 2016 and to get Tensor Flow installed on Ubuntu 16.04 one has to register for an nVidia developer's program? Here's a hint, current LTS for Ubuntu installing a widely-used AI library should require (in total):

apt-get install tensorflow tensorflow-gpu

Seriously, why make installing a widely used library a ...

Trivial bug in synaptics is so frustrating...

There's a rather annoying bug in the synaptics driver on Linux on the Dell XPS 15 9550. Basically, if you are using one finger to move around and another to click the "button" areas at the bottom of the screen, instead of taking that second finger as "click here", it sometimes interprets the second ...

Dell XPS 15 2016 on Kubuntu 15.10

Update: The battery in this machine started swelling/exploding at 1.25 years, do not order one!

So I finally got a replacement for the old laptop, which works, but is winding up out-of-RAM basically all the time. This time, instead of going for the cheap inspirons I decided to plunk for a higher-end machine ...
