Mount ntfs drive on Linux

Posted in Linux/GNU by Patrick on April 28, 2009

1. Install ntfs-3g.
2. Create a folder in /media or /mnt (mkdir /media/windows)
3. Use fdisk -l to get the name of the NTFS drive (example: dev/sda1)
4. Add the drive into /etc/fstab so it mounts automatically.

/dev/sda1 /media/windows ntfs-3g defaults 0 0


Using X with SSH

Posted in Linux/GNU by Patrick on April 17, 2009

I was working on the school computers from home trough SSH and needed to use X. Using the “-X” parameter gave me error messages when I used the keyboard mouse if I remember correctly. This worked without any error messages though.

ssh -Y -l user server

Recover lost partitions with Testdisk

Posted in Linux/GNU by Patrick on July 21, 2008

By mistake, I deleted some of my partitions and totally messed up my partition table a couple of days ago, removing the possibility of booting up my computer at all.  Luckily, I found a open source program called Testdisk.

Testdisk is a free data recovery software that can recover lost partitions and make partitions bootable again. Here’s how I recovered my Windows XP partition using a Ubuntu live-CD.

First, I enabled all uncommented repositories in /etc/apt/sources.list.

sudo su
nano /etc/apt/sources.list

Then I updated the package repository list and installed Testdisk:

apt-get update
apt-get install testdisk

When it’s installed, you can start it by typing its name in the terminal. You’ll be asked to create a log file (optional). After that, choose analyze and Intel/PC partition. Your partition table will be shown, wait until it’s analyzed. After the analyze is done, you can also choose to make a deep scan which is recommended. If you decide to recover a partition, just click the right arrow button so the current selection turns green and continue by pressing Enter. You’ll be asked to write this partition on the partition table. Do this.

That’s all, that worked for me at least. I only have some weird problems with my boot manager right now, but the partition is fully bootable.

Using SDL in Debian Linux

Posted in Linux/GNU, SDL / OpenGL by Patrick on June 10, 2008

Update the repository list and install SDL using apt.

apt-get update && apt-get install libsdl1.2-dev

For other sub libraries (optional) I used the command “apt-cache search sdl” to get the name of the rest of the dev packages. For example libsdlimage-dev or libsdlnet-dev.

Compile SDL application in g++
When I compiled my SDL_net application in Linux, this worked like a charm.

g++ -o appname file.cpp -lSDLmain -lSDL_net

Simple Ubuntu speed-up tweak

Posted in Linux/GNU by Patrick on April 25, 2008

I recently searched around for some Ubuntu speed-up tips in order to speed up my Ubuntu computer. I found an interesting thing, it’s considered a bug that slows down the application start-up time and performance considerably.

The tweak/bug

Open the /etc/hosts file as root using any texteditor and replace the following line: localhost

With the name of your computer: localhost computername
