Tech Tip: Start a Kiosk Style Machine Running a Single X11 Application
By changing your Xsession file you can start a kiosk-style machine that starts a single X11 application.
On Debian you would change the file /etc/X11/Xsession.d/99x11-common_start. In stock form there is a line that reads:
Change that to read:
On some Linux distros the Xsession file may actually be a single file rather than a directory of files. A search such as:
find /etc/X11 -iname 'Xsession*'
should find it for you. The actual line to change may differ also but should be near the end and be an exec statement or a function call that invokes exec.

Free Webinar: Hadoop
How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
