I spent today upgrading ubuntu from 9.04 ( Jaunty Jackalope) to 9.10 (Karmic Koala). However upon restarting GRUB loads and the kubuntu load progress bar screen loads. This is then followed by a blank black screen. At first I thought the upgraded had completely flattened my machine!

The first step is to get yourself to a console where you can actually do some stuff. So do a restart and when you see the GRUB loaded screen hit ESC. You can then boot into recovery mode to get into a console.

To get KDE and Xserver to start we need to get rid of the old xorg.conf. [ubuntuforums.org]

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

This should now get you some graphics.

Next we need to install the missing ati drivers. [launchpad.net]

sudo apt-get install xorg-driver-fglrx

After this you’ll want to configure the driver with aticonfig and amdcccle.

Hopefully after a reboot this should fix the problem.

This articles is regarding Mac OS X 10.6 with mysql 5.1.37.

I followed this article at hivelogic.com which required compiling mysql from source. It mostly worked with a few hitches which I’d like to share.

After following the article and attempting to run my rails app the first problem I hit was…

uninitialized constant MysqlCompat::MysqlRes

this problem seemed to be that you need to specify the atchitecture as 64-bit when installing the mysql gem. So run the below command intead when install the mysql gem…

sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-
config=/usr/local/mysql/bin/mysql_config

Or if you already installed the gem just re-install with this command. The next problem was the following…

Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

I’d move a project from ubuntu onto the mac I couldn’t find the mysql socket to use as it was specifying the wrong location. On the mac the file can be found at

/tmp/mysql.sock

So you’ll need to modify your database.yml file accordingly to point to this location

Hope this helps.

Whilst deploying a VirtualBox of Ubuntu to act as a Ruby on Rails development server I hit several issues. One of which was installing the mysql gem with the command

sudo gem install mysql

Giving me the error of

With some googling I found the solution at mentalized.net needing to install ruby1.8-dev as it was missing in my case. To solve enter the following command…

sudo apt-get install ruby1.8-dev

That solved one problem but I hit another trying to install the mysql gem.

This one took more googling but eventually found codeweblog giving a solution. Again I was missing further dependent libraries in this case libmysqlclient15-dev. To install that enter the command…

sudo apt-get install libmysqlclient15-dev

Installing the mysql gem should now work.

Hope this helps.
