It should be no news to people who have been closely following the open source driver development. This tutorial might be useful to those users who have been unaware of how to enable dynamic gpu switching at runtime. Thanks to reddit user JackDostoevsky, who wrote the steps necessary to set it up. This tutorial is just the re-iteration of that post. Read this post, if you want to follow the discussion. I have taken more conservative approach in this tutorial, therefore if you want to check git versions, follow above discussion. In case of ubuntu, I am using 13.04 (linux 3.8) with xorg-edgers ppa. In a game under wine, this setup was garbage. While in arch, I got better FPS than while using intel graphics card. Though the performance of native games were largely improved. Therefore, in this case, newer versions of driver and kernel are always better.
Most modern laptops with intel processors after sandy bridge, comes with its own graphics card (or graphics memory). If you happen to purchase such laptop with discrete graphics card from AMD or Nvidia, your configuration becomes a hybrid graphics setup. Hybrid graphics cards have long and painful history under Linux. Therefore, if you don’t follow the usual channel (your operating system provided) of installing it, you might run into lots of problems because of inconsistencies between Xorg/mesa, graphics vendor drivers and the kernel. In this tutorial, I will talk about different approaches I take while installing the driver. This tutorial is valid for Elementary OS/Ubuntu and other ubuntu derivatives as well.
Dictionary is one of the tools many people need on a computer, specially offline dictionary. In this tutorial, I will talk about such a software called Artha. According to its man page “Artha is cross-platform thesaurus based on WordNet“.
One of the software, I have been very fond of recently is minitube. It is a software that lets you watch youtube videos.
What makes minitube different from say a browser, is its ability to subscribe to channels without having to login. Also, it fetches metadata of new videos from your subscriptions, that you haven’t yet watched.
In this tutorial, I will try to explain how to install catalyst driver, fix switching problems (specially opengl part on intel cards) and some steam bugs. One reason to do this tutorial was because catalyst 13 series was not very good on my hardware in Ubuntu 13.04 or Mint 15. So, lets get started
