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

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 of that here. Suffice it to say that it was annoying getting the Windows 10 install working after ...

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

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 that includes a discreet nVidia card. Installing Ubuntu on it was... not particularly fun. All of the ...

Infrastructure Failures Suck

So this morning every single VirtualBox VM refuses to load. Ever-so-helpful "there was an error" messages. I'm assuming I'm looking at a driver, libc, or similar failure from the dist-upgrade of the host this morning. Yay. This is *not* what I needed to work on this morning.

[Update] a workstation/server reboot (Egads ...

Kubuntu 15.10 seems fine so far

So I pulled the upgrade switch on the (Dell Inspiron) laptop on Friday. It trundled for almost the whole day doing the upgrade, then rebooted to a black-and-totally-unresponsive screen, with no way to switch to virtual consoles... I did a hard-reboot, booted to recovery console and reinstalled the fglrx (proprietary AMD) drivers, then rebooted... and ...

Fire Tablet, wow, that's kinda pointless

We happened to win a Kindle Fire HDX tablet at an event. Since we've been talking about getting the kids a tablet for a while I thought "yay, sorted"... until they actually tried it.

There are no apps for the thing. Or, rather, the apps the kids actually use, YouTube, various games, Google Maps ...

KDE Seems to run on fglrx now!

So when I started testing the soon-to-be-released KDE Plasma 5.x releases they were... less-than-usable on fglrx (and would fairly frequently fail to come back from suspend/resume), so I had to switch the laptop over to Intel graphics. However, since I need to be able to run OpenCL and OpenGL/GPGPU stuff on the ...
