If you’re using Synergy for mouse and keyboard sharing, you may find that it suddenly disappears from Ubuntu. It will show up as installed in the Software Centre, but you won’t be able to remove or reinstall it, and there will be no icon on the unity bar.

If you try running it from the command line using the following command.

synergys

You may get an error similar to the following.

no configuration file found

The easiest way to solve this is to download the .deb package from the Synergy website, then open up a terminal and install it from there.

cd /home/your-name/Downloads
sudo dpkg -i synergy-1.4.10-Linux-x86_64.deb

This will then reinstall it and you should then be able to find the programme listed in the dash home.

If you find your screen resolution suddenly drops too 800×600 on Ubuntu 12.04, the following set of commands may help you resolve it. First, stop the graphical environment.

sudo service lightdm stop

Now remove all the Nvidia packages and reboot the system.

sudo apt-get purge nvidia*
sudo reboot

This will reset you to the default video driver. You now need to reinstall the Nvidia driver, which you can do by going to System settings > Additional Drivers and selecting the top option with the following name.

NVIDIA binary Xorg driver, kernal module and VPDAU library

Select this and click activate. Now reboot your system again and the Nvidia drivers will be re-installed and hopefully working again.

If you’ve tried to switch to a different Nvidia graphics driver on Ubuntu and suddenly found that X / Gnome will no longer load and all you have is a command line, you can fix it by switching back to the original driver.

jockey-text -l
jockey-text -e xorg:nvidia_current

These commands will show you a list of drivers available, and then activate the standard Nvidia driver.

To install Imagick, you would normally do this via PECL.

sudo pecl install imagick

However, when trying this on Ubuntu 12.04 LTS, you may get an error similar to the following.

checking ImageMagick MagickWand API configuration program...
configure: error: not found. Please provide a path to MagickWand-config or Wand-config program

You can resolve this by installing a few extra packages.

sudo apt-get install libmagickwand-dev libmagickcore-dev

Now try re-running the original command and it should be successful.

We’re becoming increasingly annoyed with The Library. The food is sub-standard and quite frankly that is hard to achieve when you run a student pub. It’s not like it’s any cheaper than anywhere else either so they can’t really play that card.

On the plus side though we have some very productive discussions – including the decision to rename Lil to Ubuntu.
