I could never imagine that a $100 Logitech web cam for teleconferences can make such a difference quality-wise.

ORF images in FC12 and Karmic

I have an Olympus 500 camera and I want to be able to preview Olympus raw files (ORF extension) in Nautilus. It did not work out of the box neither in FC12 nor in Karmic. On Fedora 12 I have installed ufraw and ufraw-gimp packages.  On Karmic I have installed gimp-dcraw and gnome-raw-thumbnailer packages.  This also installs ORF support in GIMP.

Making Fedora Core 12 work (cont'd)

Several things did not work in Fedora Core 12 as I wanted so I have had to make several modifications which I described here.  Finally I've got some time to make more fixes:

  1. NVIDIA fast proprietary drivers  I have GeForce GTS 250 and I want to get most of it.  Out-of-the-box driver that comes with FC12 is faster than it used to be but is nowhere near native NVIDIA drivers.  Steps to install (information was pulled from several places):
    1. su -c 'rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'
    2. yum update
    3. nano -w /etc/grub.conf and to each kernel line append rdblacklist=nouveau vga=0×31
    4. yum install kmod-nvidia xorg-x11-drv-nvidia-libs.i686 xorg-x11-drv-nvidia-libs.x86_64
    5. reboot
    6. sudo nvidia-settings and fix multiple monitor setup if you use more than a single monitor, save 
  2. Skype 
    1. Install standard Skype rpm for FC10+ from http://www.skype.com/intl/en/download/skype/linux/choose/
    2. Install missing 32-bit packages:
      yum install alsa-lib.i686 libXv.i686 libXScrnSaver.i686 qt.i686 qt-x11.i686
    3. Video should work out of the box
  3. Gnome menu: install alacarte to be able to edit system menu

  2. Then follow instructions in Installation Of X86-64 Debian Based Distributions section
It takes about an hour to download all packages and then you get:
