Ubuntu 10.10 and ATI Radeon HD 6870

So, quite some time ago I made the mistake of buying the ATI Radeon HD 6870 without first checking if it would play nice with my Ubuntu 10.10 desktop.
Turned out it didn’t 🙁

But now, there are proprietary Linux drivers released by ATI/AMD

First, you should update your system (just to be sure).

sudo apt-get update
sudo apt-get upgrade
If you’ve been using older drivers, remove them.

sudo apt-get remove –purge xserver-xorg-video-radeon
Download the install package from the AMD suppot pages and make it executable

chmod +x ati-driver-installer*.run
Run the installer as sudo-user

sudo ./ati-driver-installer*.run
Reboot

Enjoy!

The Linux 2.6.38 kernel carries the ATI Radeon HD 6000 open source support. (just fyi!)
If you encounter problems or found this post helpful, it would be nice to leave a comment below.
This way, I can adjust it to the needs of my readers.

Nasty little OpenSSH Bug

So I’ve been using my Targa NT9231 as a home sever (Running Ubuntu 10.10 server edition) for a while now.
It’s been serving several purposes such as internal webserver, irssi, monitoring and tunneling/proxy server.

As all wise people should do, I’ve been using OpenSSH to connect to it.
Solely connected to it from my netbook, as my desktop Ubuntu computer died after the purchase of a new ATI (curse you) Graphics card.
But now, I managed to revive my desktop (yay!) and wanted to log in on my server.
Setted up the key and wanted to transfer it to my authorized hosts file… but that gave me a bloody error:

Permission denied (publickey).

So I started to digg around and checked filepermissions, ssh_config file etc… But all seemed ok.
But then I found this little nasty openSSH Bug on launchpad.

Simply running “ssh-add” on the client fixed the problem!

Ssh-add adds identities to the authentication agent, ssh–agent. When run without arguments, it adds the file %HOME%/.ssh/identity. Alternative file names can be given on the command line. If any file requires a passphrase, ssh-add asks for the passphrase from the user.

I’m not sure how this could’ve helped, but hey, its a workaround that actually works 🙂

Changing date and/or time on Linux

Here’s a short and easy way to set your system and hardware clock from the command line.
Open your terminal and follow these steps.

First check the current time of your hardwareclock:

hwclock -r

Then add the right date/time to your systemclock.
In the example provided you’ll find some strange long number.
You have to read it like this (from left to right):
[01] = month (Jan) | [14] = day | [0231] = time (02:31) | [2011] = year

sudo date 011402312011

Now sync your hardware clock with the date/time you’ve just set:

sudo hwclock --systohc

Check if the hardware clock is synced right:

sudo hwclock -r

Profit!

Ubuntu 10.04 (Lucid Lynx) Release Party Ghent is under construction

It’s official! There will be a Release Party for the Ubunu 10.04 (codename Lucid Lynx) in Ghent.

I’ve just send out the news to the mailing list of Ubuntu-be and the Whitespace to confirm that i’ll organise the release party for the upcoming LTS version of Ubuntu.
The event will take place Thursday the 13th of May in the Whitespace.
I’m still looking for people whom have some knowledge of something Ubuntu-related and have the guts to give a lightningtalk or a demo.
At the moment of writing, I’ve had 1 confirmation from a guy with Balls! Mandel.
He did a talk about desktopcouch at fosdem this year, and will bring an improved version of that to the Release party.
If you have questions, let me know.
I’m available at the #Ubuntu-be channel on freenode, or just PM me (mimor) or use the comment section below.

Sorting images according to their width and height

I wrote a script to sort images according to their width and height.
I found myself in need of such a thing after my previous post on how to download 4chan images automatically.
I used this script a few times to get all the wallpapers on the /wg/ board.

After a few GB of images, nautilus starts to get a headache when opening the containing folder.
So I needed to split it up in different folders.
So here’s the script that does it.

There still seems to be a problem with character escaping when the filename contains a ” – ” in it’s title.
But I’m too tired to figure it out now.

Download 4chan images automatically with this simple script

I like to spice up my desktop with various wallpapers and have to say, that /wg/ on 4chan has been a great provider.
But keeping track of all the images, shifting forth and back and forth again between the 10 pages has been taking too much effort.
So the solution to avoid spilling too much time lurking on that imageboard, I just wrote a bash script. (Sorry Windows users)

Be careful, as this script might run a while before it finishes.
You can modify the script as you like.
You might want to remove the user-agent string or the -nd option or ad a -x for that last wget call, etc…

I’ll post later on how I actually remove the duplicated images 😉
A hint for people eager to know: fdupes

fdupes -r -f . > duplicates && echo ./duplicates > duplicates && rm `cat duplicates`

This would actually throw errors when there are spaces in the filenames.

So it was a long, verry long night.
The spirit driving me was like this:

But in the end, it felt more like:

Phishing websites collect banking credentials; mule recruitment websites entice people into money laundering; fake escrow sites defraud the winners of online auctions; fake banks hold the cash for fake African dictators; and there are even Ponzi scheme websites where (almost) everyone knows that they’re a scam. This talk will show you live examples of these sites, explain how they work, and tell you what we currently know about the criminals who operate them.

Why you should read your ISP’s Custommers Conduct Code

The idea:

Install ConnectBot on my HTC Hero, connect to my home ssh server to hook up with my Screen session.
‘Why?’ you ask? Because we can!

The process:

Create a DynDNS account
Configure my router to automatically update the DynDNS service
Set up the ssh daemon on my desktop
Set up the screen session and configure irssi
Forwarded the default ssh port (22) to my desktop PC which has a fixed IP
Drink a coffee.
Added the credentials needed to the ConnectBot’s configuration

Funny Gnome-Cups-Manager README file :)

gnome-cups-manager
------------------

Once upon a time there was a printer who lived in the woods.  He was a
lonely printer, because nobody knew how to configure him.  He hoped
and hoped for someone to play with.

One day, the wind passed by the printer's cottage.  "Whoosh," said the
wind.  The printer became excited.  Maybe the wind would be his
friend!  

"Will you be my friend?" the printer asked.

"Whoosh," said the wind.

"What does that mean?" asked the printer.

"Whoosh," said the wind, and with that it was gone.

The printer was confused.  He spent the rest of the day thinking and
jamming paper (for that is what little printers do when they are
confused).

The next day a storm came.  The rain came pouring down, darkening the
morning sky and destroying the printer's garden.  The little printer
was upset.  "Why are you being so mean to me?" he asked.
