I installed Java 6 on a Strato V-Server today that a default installation of Ubuntu 8.04 LTS.
Per default, the multiverse packages are all disabled, so you need to edit the file /etc/apt/sources.list to make it look like this:

# See sources.list(5) for more information, especialy
# Remember that you can only use http, ftp or file URIs
# CDROMs are managed through the apt-cdrom tool.

These steps are for ubuntu users. the paths may differ for other linux distributions but i think the steps are the same.
Be sure to have installed Ogre3D and code::blocks on ubuntu before you proceed. The ogre3d wiki is a good start if you search for installation how-to’s.
Step 1:
Open Code::Blocks and create an ogre3D project with the wizard.
Step2:
After creation right click the project in your workspace and choose the “Project Build Options“.
Go to the  “Linker Settings” tab and change the libOIS and libOgre paths according to my screenshot:

Step 3:
Goto the “Search …

The solution for KDE 4 users is fairly simple:
You may not have set the correct DPI for your system.
In KDE this is done in the Apearance tab in the System Settings.
Goto Fonts and there will be the drop down  for Force Fonts DPI.
Set it to 96 DPI and restart Mathematica. That’s it.

Yes, it is possible and it’s not that hard as you may think:
sudo apt-get remove cabextract
sudo apt-get install cabextract
./ies4linux
try running this command that actually worked for me:
./ies4linux –no-gui

I trashed my vista installation on my dual boot system this weekend. As we all know, vista is quite keen on controlling the Master Boot Record (BMR) .
All my tries to use update-grub failed.
After yahooing for a while I found the Super Grub Disk – a stand-alone bootable CD-Rom Image that leads you through grub update (and many other grub related tasks) with easy menus and online help.
It took me 3 minutes to get my grub installation working again.

My Brother-2030 printer denied printing for the last month and I couldn’t find redemption.
The IPP report message was:

Unable to open device “hal:///org/freedesktop/Hal/devices/usb_device_”:
Permission denied

But I figured it out. The final solution is easy:

sudo chmod 700 /usr/lib/cups/backend/usb
sudo chmod 700 /usr/lib/cups/backend/hal

I post this, because I’m not the only one having these kind of problems with HAL and a USB printer while using ubuntu (with 64 bit architecture).
Maybe this will help someone searching for a solution.
UDATE:
I updated the command with Jim Morris’ comment.
