Fingerprint reader on Ubuntu 12.04

2013/01/31

Yesterday I finally upgraded my Dell D830 laptop to Ubuntu 12.04 Precise. Everything went smoothly – great!

Today I decided to give the fingerprint sensor another try – after reinstalling my machine last year I hadn’t bothered to get the fingerprint reader to work again. (more…)

Finding the language for a xkb keyboard

2011/07/21

During the last days I was working on keyboarding issues on Linux. In our app we want to display the (xkb) keyboards that the user has installed and that are visible in the gnome panel. Displaying them is relatively easy, but then I also needed the language that is associated with the keyboard. (more…)

Cross-Platform Development and Data Type Sizes

2011/06/10

One of the problems when developing cross-platform apps is the question how long the intrinsic data types are on the different platforms. A while ago I created a table with the sizes of the different data types on 32- and 64-bit Windows and Linux, both for C++ and C#/.NET. (more…)

Lost Menu in Monodevelop in Unity

2011/06/07

Recently I got a new desktop computer on which I installed Ubuntu 11.04 Natty with the Unity UI. Yesterday I compiled Monodevelop 2.6 beta 3 (using the scripts described here) which worked fine – only when I run monodevelop the menu can’t be found anywhere: there is no menu in the monodevelop window nor in the global menu bar. Since it’s pretty hard to do any work without a visible menu, I decided to try to get this fixed. (more…)

Applications menu disappeared

2010/01/19

This morning when I turned on my laptop I noticed that the Applications menu in Ubuntu 9.10 had disappeared – well, not completely, it was still shown in the panel, but when clicking on it it only showed a tiny little rectangle instead of popping up the application list. (more…)

Firefox suddenly doesn’t resolve names any more

2009/08/07

After returning from vacation I was confronted with a really strange problem on my laptop. Firefox wasn’t any more able to load pages from certain domains. After a reboot it worked, but sooner or later it stopped working. (more…)

Fingerprint Reader Working Again!

2009/08/06

I had some problems with my fingerprint reader for quite some time, probably since upgrading to Jaunty. It took multiple attempts to read my fingerprint (more…)

Upgrading to Jaunty

Recently I updated my laptop to Ubuntu 9.04 Jaunty.

It went pretty smooth; the only drawback was (more…)

Building MonoDevelop from SVN

2009/01/15

Yesterday I managed to build MonoDevelop from SVN source. I had done it before but had forgotten how to do it, and there are no fool-proof instructions on what you need to build. (more…)

Upgrade to Ubuntu 8.10 Intrepid

2008/11/18

Today I upgraded my Dell laptop to Intrepid. After downloading 1.3 GB of data it started the installation and asked about several configuration files it thought I had manually changed. Besides that everything went uneventful, and a reboot also worked.

However, not all things are working:

  • Compiz is disabled
  • Fingerprint reader no longer working
  • Cursor keys not working; up-arrow key opens screen shot app (more…)
