Getting Nvidia-drivers to work on Ubuntu 12.10 – Quantal Quetzal


After installing Ubuntu 12.10 Quantal Quetzal on my development-machine i noticed that i wasn’t running on the Nvidia drivers for my GeForce GTX 560 Ti. And to make matters worse, the proprietary drivers didn’t work either. So i set out on a Google-hunt to find myself a solution.

It seems like there currently is a bug in 12.10 which caused the Nvidia drivers to fail. Regardless for which repository (ppa:xorg-edgers/ppa etc) you’re using and if you’re using the latest version (304.32).

Problems seem to be within the kernel, so you need to install the generic kernel including its headers. Then remove the current Nvidia-drivers and re-install them. Sounds complicated? It’s not, just run the commands below and reboot.

Edit: Notice that you need to do this each time there is a new kernel upgrade in Ubuntu. So currently you should replace linux-headers-3.5.0-17-generic with linux-headers-3.5.0-25-generic in the instructions below.

Jump over to a terminal
Ctrl-Alt-F1 and login as your username.

Install linux source and headers, make sure to use the current kernel version 
sudo apt-get install linux-source
sudo apt-get install linux-headers-3.5.0-17-generic

Uninstall nvidia driver
sudo apt-get remove nvidia-*

Reinstall nvidia driver
sudo apt-get install nvidia-current-updates

If it successfully installs, restart the computer
sudo shutdown -r now

This solved my problems with my GeForce GTX 560 Ti and i’m now running 12.10 in full GPU acceleration.

Changing font-size in Ubuntu 12.10 without MyUnity

Since MyUnity isn’t available yet in Ubuntu 12.10 Quantal Quetzal i though i’d write a quick update to my previous post which isn’t working on Ubuntu 12.10.

The process is fairly simple, just run the command below and adjust them to whatever your preferred settings are.

Just keep in mind to double-check that the fonts you’re using are indeed install. Otherwise you’ll end up in a world of hurt when you reboot.

gsettings set org.gnome.nautilus.desktop font "Ubuntu 10"
gsettings set org.gnome.desktop.wm.preferences titlebar-font "Ubuntu Bold 10"
gsettings set org.gnome.desktop.interface document-font-name "Ubuntu 10"
gsettings set org.gnome.desktop.interface font-name "Ubuntu 10"
gsettings set org.gnome.desktop.interface monospace-font-name "Ubuntu Mono 11"

Changing the default font-size on Ubuntu 12.04

Are you like me and feel a bit overwhelmed by the default massive font-size in Ubuntu? Well, if you’re on Ubuntu 12.04 you’re in luck. Since there is a really easy way to change this setting.

Luckly and thanks to some helpful individual we have MyUnity. MyUnity is a simple little tool that let you tweek most of Unity in 12.04 without having to install gnome-tweak-tool. The usage is really straightforward and it’ll have you customizing Ubuntu in no time.

This is how my default Ubuntu 12.04 looked like:

Changing the font using MyUnity:

And the result:

It seems like this tool only work with 12.04 and older, so please read the appropriate documentation if you try and use it on a Ubuntu version below this. Also, i strongly recommend that you reboot your machine after doing the settings.

Good luck and happy Ubuntu-ing!

How to get local files working with Ubuntu 11.10 and Spotify

Running in to the pesky “no codec found” when trying to play your local mp3 files in Spotify when you’re on a freshly installed Ubuntu 11.10? The problem is that Ubuntu recently changed the Qt media backend from libavcodec to gstreamer. While gstreamer plays (decodes) mp3-files just fine, Spotify wont have any of it. 

The solution is to manually add/install libavformat, libavutil and libavcodec52 from the previous Ubuntu version. Please notice that you need different set of files for the 32-bit and 64 bit version.

32-bit Ubuntu:
wget https://launchpad.net/~ubuntu-security/+archive/ppa/+build/2789249/+files/libavutil50_0.6.2-1ubuntu1.1_i386.deb

wget https://launchpad.net/~ubuntu-security/+archive/ppa/+build/2789249/+files/libavcodec52_0.6.2-1ubuntu1.1_i386.deb

wget https://launchpad.net/~ubuntu-security/+archive/ppa/+build/2789249/+files/libavformat52_0.6.2-1ubuntu1.1_i386.deb

sudo dpkg -i libavutil50_0.6.2-1ubuntu1.1_i386.deb && sudo dpkg -i libavcodec52_0.6.2-1ubuntu1.1_i386.deb && sudo dpkg -i libavformat52_0.6.2-1ubuntu1.1_i386.deb

64-bit Ubuntu:
wget https://launchpad.net/~ubuntu-security/+archive/ppa/+build/2789247/+files/libavutil50_0.6.2-1ubuntu1.1_amd64.deb

wget https://launchpad.net/~ubuntu-security/+archive/ppa/+build/2789247/+files/libavcodec52_0.6.2-1ubuntu1.1_amd64.deb

wget https://launchpad.net/~ubuntu-security/+archive/ppa/+build/2789247/+files/libavformat52_0.6.2-1ubuntu1.1_amd64.deb

sudo dpkg -i libavutil50_0.6.2-1ubuntu1.1_amd64.deb && sudo dpkg -i libavcodec52_0.6.2-1ubuntu1.1_amd64.deb && sudo dpkg -i libavformat52_0.6.2-1ubuntu1.1_amd64.deb

No Spotify-restart required, it just works ™.

Java 7 prevents FTP transfers on Windows when firewall is on

Experiencing problems with Java 7 and FTP transfers? You’re not alone since a nasty bug has slipped in to the seventh installment of Java and it’s causing major problems for its users.

The problem consists of the FTP command PORT in conjunction with Windows Firewall on Windows Vista and Windows 7. The firewall simply closed this connection which close the socket and the ftp-transfer fails.

This problem is especially troublesome for web developers that are using the java powered IDEs Eclipse and Netbeans. Since a simple upgrade to Java 7 will immediately cause the ftp transfers to stop working and the only remedy is to either close down (turn off) your firewall or downgrade to Java 6. Explicitly allowing the Javaw.exe process through the firewall did not solve the issue for me.

Oracle has been alerted of the issue on the 11th of August 2011, but unfortunately gave the bug a 4-Low in priority, which probably means that they don’t see the magnitude of the problem and we won’t see a fix for this issue anytime soon.

Installing Zend Server Community Edition (CE) on Ubuntu 10.04.3 LTS

Looking for a fast, reliable and easy PHP stack on Ubuntu? Look no further, the Zend Server is probably what you’re looking for. And if you’re developing your PHP apps in Zend Framework it’s a no brainer.

I’ve been through most of the different stacks out there including doing the complete LAMP-installation from scratch. Maintenance is troublesome and configuration (and lack of personal configuration-documentation) makes most of my installations unmanageable after a year or so. Until i found Zend Server, especially the Community Edition which is a completely free PHP stack backed and built by the people over at Zend Technologies Ltd.

If you’ve ever looked into different PHP frameworks you’ve probably stumbled over Zend Framework, which ties in extremely well with the Zend Server. So if you’re developing PHP apps using Zend Framework, the Zend Server will make your life a lot easier.

Zend Server is a pre-integrated PHP application stack including the most up to date setup and configuration for your server (VPS, Amazon AMI etc). It includes Bytecode accelerator (Optimizer+), Zend Data Cache, A certified PHP distribution, Zend Framework, Apache (or IIS integration), Out-of-the-box connectivity to all common databases, Java code connectivity and a Web-based PHP administrator console.

I recently setup another Ubuntu Server with Zend Server CE and thought i’d quickly run through the various commands you need to be up and running within no-time.

I strongly recommend that you install this on a fresh server since Zend Server is preconfigured with webservers, databases, php etc out of the box. If you already have Apache, PHP etc installed on your machine you’re probably going to run into trouble. Also please keep in mind that you need to have sudo-access for this.

Installing Zend Server Community Edition (CE) on Ubuntu 10.04.3 LTS

Start by adding the official Zend debs to your distribution.
sudo nano /etc/apt/sources.list

And the following snipplet in the bottom of the file
deb http://repos.zend.com/zend-server/deb server non-free

Add the Zend’s repository public key
wget http://repos.zend.com/zend.key -O- | sudo apt-key add -

Now synchronize the repositories
sudo apt-get update

Finally install Zend Server with PHP 5.3
sudo apt-get install zend-server-ce-php-5.3

All done, you now have Zend Server Community Edition installed!

You can access your installation via https://localhost:10082/ZendServer (secure) or http://localhost:10081/ZendServer. If you cannot access your server via a browser on localhost, just replace localhost with either the servers public IP or a domainname.

From here on there are millions of opportunities, but i’ll try and cover those in another guide. Good luck and happy coding!
