1. Linux has no GUI, unlike Windows or MacOSX. You can install several incompatible third-party GUIs, but no software will use it until you install several other incompatible third-party "toolkits", and then some applications which use different toolkits and cannot interoperate.10/28/2018 02:45 AMPosted by AutomuteThere are plenty of easy to use distros built around Canonical and *buntu.
2. That third-party GUI apps are just frontends to console tools and as such they are unusable, as there is no way to communicate with them, outside of input streams. This is why GUI in Linux is non-functional.
3. Ubuntu doesn't even have a Control Panel equivalent, unlike RHEL or SLED (you have to pay for them, though). Due to (2), and lack of Windows Registry, you cannot customize your system outside of editing cryptic text files in unexpected places.
4. "Install printer driver herself"? What do you mean, downloading a tarball and compiling and installing it via cryptic commands? And the printing system on Linux is also third-party, donated by Apple, and completely separate from the rest of the system.
5. Linux had been preinstalled from time to time, but as it is unusable if you don't have a personal system administrator for fixing problems which leave you without GUI, sound or network, editing config files and entering weird commands into a terminal, it never gained any traction, and never will, because the last thing people want from their computer is to roleplay a student/sysadmin.
