With the ever changing landscape in IT, many enterprise environments are looking for ways to reduce or eliminate downtime, improve security, reduce footprint, and achieve application portability. Red Hat Enterprise Linux Atomic Host provides a way to achieve these goals. In this blog we cover the steps needed to setup Satellite 6 to deploy RHEL Atomic Hosts within your environment.

The act of hooking-up a dishwasher is not unlike adding a Linux system to an existing enterprise IT environment. When you deploy a Linux system, it too needs to be “hooked-up”. As the data that flows through your environment consists of different kinds of objects (e.g. users, groups, hosts, and services) the associated identity information is not unlike the water in your dishwasher. Without this identity information(or, in the case of the dishwasher, without the water) your new machine is less than useful. Ensuring that your new system (or new dishwasher) is properly connected is important, if not essential.

I have an old Asus 1000HE Eee PC (32-bit, 2GB RAM, 128GB SSD).  Fedora 21 with Gnome Shell runs ok, but as I only use this netbook to browse the web, I figured I’d try to figure out how to launch Chrome as the desktop environment, cutting Gnome Shell out completely.  In the process of trying to determine which lightweight window manager I would use, I discovered that Google Chrome (my browser of choice) includes it’s own called Ash.  So, setting this up was as easy as creating a single file, and simply selecting “Chrome” as my login session from GDM.

/etc/X11/sessions/chrome.desktop

[Desktop Entry]
Name=Chrome
Comment=Chrome Browser
Exec=/usr/bin/google-chrome --open-ash --ash-force-desktop --ash-host-window-bounds="1024x600"
TryExec=/usr/bin/google-chrome
Icon=
Type=Application
DesktopNames=Chrome

This isn’t a perfect solution, but it’s pretty neat.  A few problems:

• Triggering a download crashes the browser, as Chrome can’t launch the Gnome (GTK?) download widget
• No battery,audio, or wifi system icons
• Initially, the desktop was off-center.  Apparently, the netbook screen size (1024×600) was odd, so it needed to be explicitly specified with the “-bounds” parameter.

Next, I’m going to give Android-x86 a shot on this Eee PC.

Reminder to self: When installing EL7 (RHEL7/CentOS7) on a old Acer Aspire 5520 laptop, fetch and install the following RPMs from elrepo.org:

• kmod-ath5k
• kmod-nvidia-304xx-304
• nvidia-x11-drv-304xx-304
• kmod-forcedeth
