Every now and again I get ticked off with something to do with planned 'features' in gnome 3. I'm still not happy about gnome-screenshot, but I patched and compiled my own version, so I'm doing alright. I don't really like the transition of menus from the, well, menu bar of applications to the top bar of the gnome desktop, but it's not a great issue.
Oh, and I don't really use vanilla gnome 3 anyway -- I've got a desktop set up with a top panel, and bottom panel, static desktops etc. The latest 'feature' which is making me want to move to a different desktop is the planned change in the
use of the middle-button so that it no longer can be used to paste text.
(of course there's a bit of inconsistency here: KDE turns out to have a remapped middle-click, the screenshot application needs a few more clicks than the old gnome-screenshot etc.)
I've toyed with the idea of changing desktops in the past, and for a while was running nothing but KDE on my laptop (I'd rather switch on my 'casual' computer first, before making the transition on my work computer), but for some reason I switched back. I actually can't remember why, but something really annoyed me about KDE.
Before I forget: a good reason to try another desktop is simply to reassure yourself that you do have alternatives if your chose DE suddenly turns into something you can't work with.
Anyway, time to give it another go. But what desktop? I like the idea of going for KDE since it's 'the other desktop' -- it's been around longer than gnome, whereas lxde and xcfe are mere babies in comparison. Alternatively, one could always piece together a custom desktop using e.g. fluxbox. Or switch to something completely different, like xmonad. Or something a little bit different, like Enlightenment. I think I should probably be going for LXDE (I instinctively don't like XFCE), but let's go for KDE first.
Finally, the main danger is switching desktops and expecting the new one to act exactly like the old one (minus the bad parts, obviously). Which is pretty much how windows users (myself included once upon a time) behave when trying out linux for the first time.
Anyway, time for a week in KDE (4.10.5).
Here's my gnome desktop at the time of switching:
In addition, I'm using
Guake, and my network manager is
wicd.
So let's see what KDE will look like at the end -- whether I'll be able to use KDE as KDE, instead of as an ersatz gnome.
Step 1. Install KDE
sudo apt-get install kde-full wicd-kde kdesudo yakuake
I selected kdm.
Step 2. First boot
Reboot and make sure to click the little sun icon to select the desktop you want to use, in my case KDE/plasma.
2.1 Switching workspaces
I next set up proper workspace switching so that it behaves like in...gnome (falling into the old trap of making the new desktop just like the old one)...i.e. ctrl+alt right/left arrow.
Go to System Settings/WorksSpace behaviour, Virtual Desktops -- I incrased the number of desktops to 6 (1 row), then clicked on the Switching tab -- I set shortcuts for
Switch One Desktop to the Left and
Switch One Desktop to the Right to ctrl+alt+left and ctrl+at+right.
2.2 Disable nepomuk
At this point I noticed that I was using 100% of the CPU.
virtuoso-t was chewing up a lot, as was
nepomukservices. I had a look at this post:
https://forum.kde.org/viewtopic.php?f=66&t=98892
I first went to Search and Indexing (in the menu), unchecked Monitor file and directory changes, Enable when running on battery, Only when computer is not being used. You can also go to System Settings/Desktop Search and uncheck Enable Nepomuk Semantic Desktop.
2.3 konqueror crashing
I also had repeated issues with konqueror crashing when clicking on links, but it seems to have resolved itself after
disabling nepomuk.
2.4 guake/yakuake
Guake worked from the beginning -- I didn't have to set it up at all. However, I still ended up changing to
yakuake since I figure it's a bit more KDE like.To get yakuake to remember changed settings (e.g. height, width) you'll need to close it manually. Restarting it will use the new settings. Not sure how I got yakuake to autostart -- I think it just happened.
2.5 The bottom panel
I had a difficult time figuring out how to add shortcuts to the panel, and once I had accidentally figured it out, I promptly screwed up the entire bottom panel, then managed to fix it again.
2.6 Keyboard shortcuts
I then had to figure out how to
bind shortcuts to opening applications -- right-click on the menu ('kicker'), click Edit Applications, select your application, advanced, Advanced, Current Shortcut Key.
A more general approach to creating shortcuts was shown to me by an anonymous commentator (see below this post) -- I've posted the screenshot provided to me below:

| shortcuts, gestures and whatnots |
2.7 Update notification
I promptly removed the
Update Notification widget -- it was driving me crazy and reminds me too much of windows. I first tried simply disabling the update notifier:
I then did
apt-get autoremove update-notifier-kde. The problem -- even after a reboot I still get notifications about updates! I then did System Settings/Software Management, and click on the tiny, tiny button on the far right (level with the search field), and then click on settings and set
Check for updates to never. This finally seems to have done it.
2.8 Theme
I also changed from the default 'air'
theme to 'oxygen'.
2.9 Gnome/GTK programs in KDE
To make gnome (well, gtk)
programs look acceptable under KDE,
install gtk2-engines-oxygen and
gtk3-engines-oxygen and reboot
.
2.10 Tap-to-click with synaptics
I can't get synaptics
tap to click to work. Based on the odd post I tried
gpointing-device-settings, but while there's a checkbox to disable tap to click, it won't enable it. I then installed
kde-config-touchpad and was happy again. Funnily enough this made me discover that middle-click is mapped in KDE -- the one reason I wanted to explore something other than gnome...oh well.
2.11 Conky
To get conky to work properly I only had to make some minimal changes.
/etc/conky/conky.conf:
background no
own_window yes
own_window_type normal
own_window_argb_visual true

And I've discovered that I really like the hot corner (top left) in gnome. There is a hot corner in kde too, but it does slightly different things.
KDE is pretty but it still gives me the occasional feeling that I'm using windows due to the bottom panel, the menu on the left and the task tray on the right, but these are things I'll hopefully grow out of. But yes, KDE is pretty -- very pretty. And it's pretty fast too.

| And one just to show how versatile KDE is -- you can even make it look (almost) like gnome 3 |
So...now it just remains to see how I feel after a week or so. The baby duck syndrome is pretty powerful...and I'm already well on my way to turning KDE into GNOME. But then, isn't the versatility of KDE the real selling point?
Postscript:
I ended up re-enabling nepomuk and spent some time struggling with akonadi to get kmail working -- the key to getting akonadi to work was to install the same server as the backend. In my case I did:
sudo apt-get install akonadi-backend-mysql mysql-server
