Change Rhel7_client-x64 configure as kiosk
I have a RHEL7 machine that uses X11 for display. We have a need to make this sort of like a kiosk machine. We need it to have a solid black desktop background, no desktop icons, and no right-click menu for the community user account configured on the system.
I'm drowning in all the info about X11, Gconf-editor, gnome, etc. etc. Can someone please point me in the right direction to do this? Thanking you in advance.... |

Because if you're not, it's not really a good choice, since you will not have access to bugfixes/security patches/updates, and it will make installing things MUCH harder in the future. If you need a SERVER CLASS distro, like RHEL, use CentOS instead. If you are paying for RHEL support, calling Red Hat would get you going faster. |
We are paying for RHEL support but for reasons I can't go into we can't use xguest. We also have to use RHEL7

If you're paying for RHEL7 and you're locked into it, then contact them for assistance. If it's browser based, you have a low-tech option; run the browser in full-screen mode and disable the F11 and F4 keys via the keyboard mapping utility...map them to some CTRL-ALT-SOMETHING that you know option, and disable the right mouse button. Can do both through Gnome or KDE easily. F11 takes the browser full-screen, no border. Disabling that key keeps it that way. Disable F4 so no one can hit ALT-F4 to CLOSE the browser, either. You're left with one window, full screen, no way to do anything but interface with what's on it. |
Icon removal/black desktop background
DOD requirements - that's why we're locked into RHEL7 and why also it can't be a pure kiosk, has a lot to do with the software that will be installed and run over top of the base OS.
I figured out the right click part. Used the command xmodmap -e 'pointer = 1 2 0 4 5 6 7 8 9' in the .bashrc file within the users' home folder that I'm locking down. Logged out, and in again, no ability to right-click anymore. As far making a plain black background, have no idea. If I use the gconf-editor command and go to "Desktop", then gnome, then background, I see two choices Primary and Secondary Colors. The values are in hex. Someone speculated that black in hex is ffffff. I changed both of those values to that but nothing happened. I've read where this can be easily done in Nautilus. I checked and have Nautilus installed. But everywhere I read this it says that if I bring up gconf-editor again, I should see Nautilus as a choice under "Apps". The only choice there is gconf-editor. Nautilus doesn't appear. As far as removing the Home and Trash icon on the users' desktop, again, supposedly easily done in Nautilus. But again, it's apparently done within gconf-editor again, under App "Nautilus". Don't have that choice there. |

Which goes back to disabling those keys in the window manager, so it stays there. |
Lock-down
You're right. It's more of a lock-down than a kiosk. The system is one in which sailors will sit in front of on a ship. That's all I can say. we don't want them being able to bring up a terminal window, no icons on desktop, plain black background.

And if you want no icons on the desktop, you'll have to enable the Gnome panel/launcher. Which opens holes of its own. A single-purpose icon on the desktop that can't be modified is far safer. |
