Ubuntu Multimedia :: Multiple Machine Multiple Display Wall?

Aug 4, 2010

We are working on a project to create a display wall of 8 monitors arranged as 2 high by 4 wide. Each monitor is connected to a single machine and all machines are networked with a master machine with its own, seperate monitor.

Our goal is to get the 8 machines to share a single desktop, with the master machine acting as the server. We have looked at using Xinerama or NMM, but we are unsure about how to get started configuring the multi-machine, multi-head display.

Fedora :: The Service Does Not Use The System Environment Variable For JAVA And JRE Setup?

May 6, 2010

i have added a tomcat startup service using chkconfig. I have set up JAVA_HOME and JRE_HOME as well ass alternatives to point to the correct location.I have an init script in /etc/init.d. When i start the tomcat service using [ /etc/init.d/<x> start ] everything works fine and the environment variables for JAVA_HOME and JRE_HOME are used correctly.Now i added the service <x> using chkconfig --add so that it can start on boot up. But now the service does not use the system environment variable for JAVA and JRE setup by me.Also after complete bootup if i try to start the service using [ service <x> start] the environment variable in the shell are not used. don't want to exclusively declare variables for JAVA_HOME and JRE_HOME in the init script.

General :: Matlab 7.5 Compiled Runtime Installation: Getting A "No Java Runtime Environment Was Found On This System"?

Oct 15, 2010

I am trying to install the Matlab 7.5 compiled runtime for 64-bit Linux (MCRInstaller.75.glnxa64.bin) and keep getting a "No Java Runtime Environment(JRE) was found on this system." error message.

I understand the JRE is bundled with MCRInstaller and will self-compile/install. However, I don't have admin access, could this be the source of the problem? If so, how could I fix it (not sure how to direct it to install locally without going into the source code)?

I got around this error before, but stupid me didn't write down what I did and I forgot.

Debian Multimedia :: Select Multiple Desktop Environment Using Startx?

Jan 25, 2011

I use Debian Squeeze and I have the following desktop environment installed: fluxbox, lxde, openbox and icewm. I make login in text mode and I start X using startx command manually in terminal. When I do that, fluxbox is loaded, because my ~/.xinitrc is configured this way:

# fix dbus problem
eval "$(dbus-launch --sh-syntax --exit-with-session)"
# start session
exec startfluxbox


And "%session" is the variable value (fluxbox/lxde/openbox/icewm) chosen during the graphical login. This script works with Slim, but I want to login in a non-graphical mode. Could I use this script somehow to do a non-graphical login using startx? Is there some way that I could run startx with some parameter that it would pass the "%session" value to .xinitrc?

Server :: XEN Machine Hung Sometimes Caused By Java?

Jul 23, 2010

I have several xen virtual machines but the issue is occurring only on the one of them. Sometimes (4 times per month) the server hung. I can ping this server on the network but I am not able to login to server using local console or ssh session.


I sounds like the issue is caused by some Java application. But I am not sure is this message is related to root cause or the Java is impacted as a result of issue.

Could you help me with this? I need more details regarding error message described below and I also need to identify the root cause and resolve the issue. Is there any way how to determine which Java application is causing this issue?
