I’ve seen the future of mobile computing and it (unfortunately) is dongles

The last time I’m going to refer to it as the Windows key is in the title and in this sentence. We’ll go by it’s rightful name, the Super key. To make mine extra super, I cover the Windows logo with a Linux Penguin logo. I got this one from ThinkPenguin.com:

After using a Mac for about a year, I started to really like the approach of using the Command key for clipboard operations. Mostly because I still use the command line very often and I want to continue using Control+C for cancel. It’s like having your cake and eating it too. Why not put the Super key to use on my Ubuntu system for the same purpose?

We’ll cover the setup on several different applications. I like to add Cut, Copy, Paste at a minimum as well as Select All and Undo (since the A and Z keys are also in the vicinity). In cases where it’s possible, I’ve also mapped Redo as Shift+Super+Z since some programs would use Shift+Control+Z for Redo.

I had a weird problem recently that I solved, and it was mostly due to my mis-configuring of my Ubuntu laptop. I finally figured it out when setting up my new Dell XPS Developer Edition laptop, so I wanted to share.

The situation: I would go to my local library and couldn’t connect to their wireless internet. But if I disabled dnsmasq and restarted the network-manager service, it would work fine.

What I didn’t realize was happening is dnsmasq was taking over local DNS control from the systemd-resolved service. What is systemd-resolved and why is it important? The man page reads:

systemd-resolved is a system service that provides network name resolution to local applications. It implements a caching and validating DNS/DNSSEC stub resolver, as well as an LLMNR and MulticastDNS resolver and responder.

My library uses a captive portal. When you connect to their network it brings up a page that makes you agree before actually being able to use the network. systemd-resolved has all the know-how to handle that – dnsmasq doesn’t.

I love dnsmasq and don’t want to loose it’s functionality. I want to use both the system resolved (pronounced resolve-D) and dnsmasq. Here’s how to have your cake and eat it too.

My company helped me purchase a new Dell 7390 XPS 13 Developer Edition. The biggest hurdle I had when setting it up was getting my external monitor to work correctly. It’s a standard HD monitor (1920×1080), and the laptop screen is 4K (3840×2160) – known as a “HiDPI” monitor because while it’s run at 3840×2160 it’s scaled 200% so actual humans can read the fonts.

This presented a problem because the scaling was affecting the external monitor – it was appearing as if the resolution was half of HD – 960×540. Hello 1990s!
