Internet services that are not required for system or application processes must not be active to decrease the attack surface of the system. X Windows has a long history of security vulnerabilities and will not be used unless approved and documented.
So there is this rule that claims X is bad. It seems that if in CentOS7 (i.e. RHEL7) removing
xorg-x11-server-common results in the following also being removed
xorg-x11-drv-fbdev xorg-x11-drv-evdev xorg-x11-drv-v4l xorg-x11-drv-ati xorg-x11-server-xorg xorg-x11-drivers xorg-x11-drv-intel xorg-x11-drv-synaptics xorg-x11-qxl xorg-x11-vmware xorg-x11-wacom xorg-x11-void xorg-x11-nouveau xorg-x11-vmmouse xorg-x11-ves xorg-x11-dummy
In doing so after a reboot I no longer have a graphical login at the console, doing a
init 5 or
systemctl isolate graphical.target results in an error, it's now like sitting at a commodore hooked up to the living room tv but black & white not black & green.
My question is, for a server in a work environment where users would not sit at a console but rather VNC or remote in over the network, will graphical programs like libreoffice, firefox, the graphical user manager in gnome
system-config-users work? Or does removing xorg bring us back to the 70's style of computing? How ingrained is Xorg-x11-* would gnome and right-click new terminal still work?
update: so it appears it is very needed if you want to have any kind of windowing including your mouse and keyboard working.
- xorg-x11-drv-evdev = input driver for Linux's generic event devices, it therefore supports all input devices that the kernel knows about, including most mice and keyboards.
- can't install that or
- thanks for playing, I recovered by doing
yum install x11-xorg-driverswhich basically reinstalls everything including server-common
