The development process of RHEL was always a bit of a riddle for me. As far as I understand - RHEL is forked from an older version of Fedora. The RHEL team is responsible for back porting security patches for the packages available in RHEL repositories. Red Hat does seem to have a large group of developers. Are they mostly contributing to open source projects available in RHEL? If so, does that mean that Red Hat pays its developers mostly to help the open source world?submitted by Reish

Evolve OS, a Linux distribution that it's still under development and which boasts a beautiful new desktop environment called Budgie, has just got its third Alpha release.

I've just completed a new build (specs below) and I'm trying to install my OS.
Initially I was going with Mint 17 (Cinnamon), so I burned the ISO onto disc and loaded it up. I problem I'm having is my mouse and keyboard work for only ~10 seconds before they freeze completely. I know it's the mouse because if I disconnect the unified wireless USB thingy and reconnect it again they work before freezing again.
I'm currently using a Logitech mk520 wireless combo but I tried a wired Dell keyboard with a different wireless mouse before and the problem has remained.

After failing to find a solution for Mint I thought I'd try a different distro and see if that helped. Loaded up Ubuntu 14.1 and the problem persists.
Can anyone advice on what I should try next?submitted by albion70

With the Linux 3.17 kernel that's now officially under development since yesterday's Linux 3.16 release is now support for Xen EFI.
With the upcoming Linux 3.17, it's possible to boot using (U)EFI under Xen Dom0. Daniel Kiper who worked on the Xen EFI patches explained, "Standard EFI Linux Kernel infrastructure cannot be used because it requires direct access to EFI data and code. However, in dom0 case it is not possible because above mentioned EFI stuff is fully owned and controlled by Xen hypervisor. In this case all calls from dom0 to EFI must be requested via special hypercall which in turn executes relevant EFI code in behalf of dom0."
The Ubuntu developers are constantly working on their Unity desktop environment and most of changes and new features will most definitely land in the next versions of the operating system.

I have a script that I am trying to run with Cron. The script is using xdotool to locate an active firefox window and send a ctrl-Tab keystroke to it to switch tabs in the Firefox window. I would like the script to run every three minutes. At the momnent the script is called firefox and is located in my /home/dave folder.
When I run the script from the command line like this ./firefox, it works perfectly. When I attempt to add a line to my crontab and run the script on a schedule it's not working. I am seeing this error in the email generated by Cron,No protocol specified Error: Can't open display: (null) Failed creating new xdo instance
Currently my script looks like this:#!/bin/bash export DISPLAY=:0 xdotool search "Mozilla Firefox" windowactivate --sync key --clearmodifiers ctrl+Tab
The line in my crontab currently looks like this:* * * * * /home/dave/firefox
A previous incarnation of the line in Cron looked like this:* * * * * env DISPLAY=:0 /home/dave/firefox
That one didn't work either.
I am currently logged into the machine as user dave, the crontab I'm using is for root and this all running in Lubuntu. I'm definitely a little unclear on X sessions and how those pertain to users, but from the errors I'm getting in the mail generated by the cron task, I suspect that that is where the problem lies. Can anyone shed some light on what I might need to do here to get this script to run properly?
Thanks in advance.
Edit: Yes, I understand that presently my Cron script is going to run every minute not every three.submitted by theotherdave
