Re: removing of sddm (debian 9 -kde5) to start in console mode then startx to start kde5



Stephane asked for a help and got it. I also given him the best advice based on my experience with "startx" shell script.
"$ sudo systemctl start display-manager.service" is most fail-safe command to start desktop environment from console session on any systemd-adopted distro.

Here is some example disadvantages of using "startx":
* "startx" often requires user to go extra mile and configure or keep track of changes in ~/.xinitrc ~/.xsessionrc scripts.
* If you use Xfce and will start it by "startx" you will pass on display manager and greeter, and if you manually lock your session at some point with xflock4 you will get black screen without any way of unlocking it other than logging into another tty and doing it from console. This is understandable, because by using "startx" with Xfce you passed on session and seat management.
* Some users could fire "sudo startx" at some point and give themselves a good chance to ruin their system.

You can use whatever you want, as I already said it doesn't mean "startx" doesn't exist or work anymore, and you have to understand there is many ways to do something in Linux, but just any way doesn't always means it is the right way.

To all respectable people, go ahead and grab pitchforks and torches there is somebody with different\wrong opinion on The Internets.

Look it up, it [startx] was deprecated for quite some time.

==========================================================================
* Only the gdm3 display manager supports running X as a non-privileged
  user in stretch. Other display managers will always run X as
  root. Alternatively, you can also start X manually as a non-root user
  on a virtual terminal via startx.

When run as a regular user, the Xorg log will be available from
~/.local/share/xorg/.

Looks supported to me.
