At work, I can now use 2 screens again, thank goodness

The 2 screen set up is slightly different now to how it was with KDE 3. Previously I had 2 separate X screens defined, one on each physical screen. The downside of this is that you can’t move windows between screens (the mouse pointer is the only thing that can do that). If you have Thunderbird email in one screen and the Firefox browser in the other, when you click on a link in an email message you get a message saying you can’t open another instance of Firefox because there’s already one running. So, the work-around is to just copy and paste the URL between the applications.

Anyway, with my new configuration I used the nVidia configuration utility (nvidia-settings) to configure Twinview. Now I can happily move windows between screens with no problems. Pop-up dialog boxes tend to appear on a random screen, but it’s not a big problem

So, overall, KDE 4.2 is what KDE 4.0 should have been to begin with.

Finally, KDE is back! Congratulations to everyone involved

Fedora 9
To upgrade, I followed the excellent instructions at http://www.gagme.com/greg/linux/f9-tips.php. The key point is to use the ‘preupgrade’ package to sort everything out:

yum -y install preupgrade
preupgrade

This downloads new F9 versions of all the RPM packages you have on your system and then sets everything up so that when you re-boot your machine it will start F9.

It’s an excellent idea, and for me It Just Worked.

KDE 4
KDE version 4 is all rather new. Initially I had version 4.0 installed. The biggest drawback to this version was the absence of the Fuzzy Clock. However, I’m pleased to say that on my first ‘yum update’, my system was upgraded to KDE 4.1, complete with Fuzzy Clock. Whilst version 4.0 was looking a bit rough round the edges, 4.1 is a far more polished affair.

One of the new features (on System Settings, Desktop, General tab) is the ability to ‘Enable desktop effects’, which makes the whole machine much more Mac-like in the prettyness of the desktop. However, I noticed that with this turned on, even when nothing else was running, I was using about 50% of my CPU power just to run the desktop. So I turned that off

The other annoyance in KDE4 was the lack of launch buttons on the panel for my favourite applications. This was really getting on my nerves until I realised that the default ‘tab’ shown initially when clicking on the ‘K’ menu button is the Favourites tab. To add things to the Favourites tab just find the application in the labyrinth of menus on the ‘K’ menu, click it with the secondary mouse button and select ‘Add to Favourites’ from the context-sensitive menu. Now all your favourite applications are just 2 clicks away on the ‘K’ menu button.

UPDATE: Neither KDE 4.0 nor KDE 4.1 can cope with dual screen display systems! I’ve seen comments that imply dual screen configurations are very rare and so fixing the problems is not a priority. Boo : -( See my comments below for details.

The main reason I use KDE rather than Gnome or another system is the Fuzzy Clock. The clock in the lower right hand corner of my screen uses real English to tell the time. So, for example, 11:22 would appear as ‘Twenty past eleven’. The fuzziness is adjustable, but the minimum setting changes the time every 5 minutes, which is more than good enough for most things. This means that the clock will say ‘Twenty past eleven’ until it changes to ‘Twenty five past eleven’.

Recent versions of KDE also include a nifty utility called ‘kbluelock’. When you enable kbluelock, it scans for Bluetooth devices nearby. Select your phone from the list shown, and if your phone ever goes out of range, kbluelock will enable the screen saver, automatically locking the screen. Effectively your phone is being used as a ‘presence detector’ – it indicates if you are at your computer.

This reminds me of the Active Badge system, although that used infra-red technology rather than Bluetooth wireless. I like the idea of using my phone to indicate where I am (within limits
