Hello comunity
I hope someone could help me with those two questions, which I couldn’t find answers to elsewhere…
What would be a good Display Manager alternative to run with KDE5 OpenSUSE, instead of SDDM?
How do I change the display manager?
The SDDM seems to be useless when it comes to remote access.
You can use kdm, gdm ,xdm , what you want.
To change, see Chapter 5.2:
https://doc.opensuse.org/release-notes/x86_64/openSUSE/Leap/15.0/#general
Thank you for the link, there’s a section covering how to change it and it also helped me to verify that I’m running SDDM.
However, for the which part, I was hoping for some advice, as I know that in theory I can run any. I guess I’ll try KDM, since I believe that had been the predecessor for many years in OpenSUSE distros.
I have chosen for KDM because I could configure
UserCompletion=false
UserList=false
there which I could not with SDDM (at least not when I stumbled into SDDM).
I’ve the same issue, I want to access remotely (with VNC) to a server but with sddm as display manager it doesn’t work.
This document https://doc.opensuse.org/documentation/leap/archive/15.0/reference/html/book.opensuse.reference/cha.vnc.html states that KDE Plasma5 with sddm doesn’t accept remote connections (it doesn’t support the XDMCP protocol).
On a server, with sddm if a run a vncserver instance in a konsole as ‘normal’ user I cannot access remotely (as expected) to the server but, if I run it with root user I can !
I don’t want to run vncviewer as root so I tried to switch to xdm (and rebooted) but nothing changed …
Any idea?
When using xdm, you should of course configure it. I do not think it accepts remote by dedault configuration for security reasons. You do not explain anything on hat you did to make remote access possible.
Hi Henk,
I simply modified in/etc/sysconfig/displaymanager the parameter :
In /etc/X11/xdm/xdm-config I have found:
Ciao

Sorry, but it is not clear to me if you changed the configuration before you posted, or after mu suggestion.
Does it work now?
If not, did you also think about a firewall that may block access?
I modified the configuration after your suggestion but is still not working.
Firewall is not enabled on server nor on remote client …
I’ve also tried with lightDM but with the same result.
You could check if the posrts are listened on.
I always do this (as root) with
netstat -tulp
but for this you need the deprecated tools. I assume the replacement is
lsof | grep LISTEN
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1001/gvfs
