Installing KDE 4.2 in Intrepid Ibex

shakir — Wed, 18 Feb 2009 06:21:29 +0000

I've been a KDE user since I started using Mandrake Linux 8.0, which if I remember correctly by that time bundles KDE 2. It was until recently that when Kubuntu 8.10 includes KDE 4 by default rather than KDE 3, I switched to GNOME.

KDE 4 at that time for me was an unfinished product where it's not ready for prime time. The desktop effects were slow, many features of KDE 3 programs were still not ported, bluetooth was not working, and most important of all I can't run it in dual screen.

This has changed recently when KDE team released KDE 4.2. There were so many bugfixes and improvements that I think it's time for me to go back to KDE.

I've published an article on how to install KDE 4.2 in Ubuntu 8.10 (Intrepid Ibex) at Techrecipes.

Set up dual monitor in Linux

I’ve just bought ViewSonic VA2226w from Lowyat, and has been able to use it in dual monitor mode with my XPS M1330 (nvidia based) and Kubuntu. The ViewSonic that I bought is a 22" LCD monitor with resolutions up to 1680×1050 (only just as high as my 15.2" Inspiron 6000′s screen)..

I was using nvidia-config to configure the dual display, and after some trial and error, I come out with this /etc/X11/xorg.conf file:

“DeprecationWarning: SessionMiddleware is moving to beaker.middleware in 0.8″ error in (K)Ubuntu

shakir — Wed, 14 Nov 2007 08:55:24 +0000

I’ve been getting this error when running paster for my Pylons project:


shakir@herugrim ~/Misc/workspace $ paster serve –reload development.ini
Starting subprocess with file monitor
/var/lib/python-support/python2.5/pylons/wsgiapp.py:249: DeprecationWarning: SessionMiddleware is moving to beaker.middleware in 0.8
  app = SessionMiddleware(app, config.global_conf, **config.app_conf)
/var/lib/python-support/python2.5/pylons/wsgiapp.py:254: DeprecationWarning: CacheMiddleware is moving to beaker.middleware in 0.8
  app = CacheMiddleware(app, config.global_conf, **config.app_conf)
Starting server in PID 8550.
serving on 0.0.0.0:5000 view at http://127.0.0.1:5000

On my quest to solving it, I uninstall Pylons (its whole bunch of dependencies);

sudo apt-get remove python-pylons

and install it back again, but this time using easy_install;

sudo easy_install Pylons

Yeay, I’m now good to proceed. Happy coding to me
