How to set default session type to Plasma for sddm

[Roderick Johnstone]

Hi

How do I set the default session type for sddm to offer to be Plasma? 
I'm currently getting Gnome Classic? This is F22.

Thanks

Select Plasma on the login screen.
Login.
That's it. The next time it should be preselected to Plasma.

Thanks for responding Patrick, but I was hoping to be able to have this 
pre-configured at install time so that I didn't have to go round all my 
users and show them how to do that.

That *should* be a setting in /etc/sddm.conf but I don't actually see it 
in the man page. Hmmm.....

Check here:  https://wiki.archlinux.org/index.php/SDDM

You want to edit /etc/sddm.conf

under [Autologin]
Session=plasma.desktop

If you want to change the theme:
under [Theme]
Current=breeze
CursorTheme=breeze_cursors

Thanks, but I already tried that, and also copied the 
Session=plasma.desktop to the [General] section of sddm.conf as I'm not 
using autologin, just in case that worked. It doesn't work for me. Does 
it work for you?

The kickstart docs at: 
https://github.com/rhinstaller/pykickstart/blob/master/docs/kickstart-docs.r... 
still say to put
xconfig --defaultdesktop=KDE
in the kickstart file.

That creates /etc/sysconfig/desktop with a line:
DESKTOP=KDE
but that doesn't work either (it used to work when I was using kdm).

I've also tried variations with DESKTOP=Plasma and with KDE and Plasma 
in quotes.

So I'm a bit stuck.

Just out of curiosity , are all of your users kde-only?  It doesn't address
your question, but if the only DE installed is the only one they want,
they'll always get what they want :)

Thanks, thats a nice idea. Yes, mostly only KDE users.  But I need 
another DE installed because Plasma doesn't work with X2go any more, 
unfortunately. Currently I'm evaluating xfce for that use case.

And then I like to have gnome installed as well as occasionally someone 
will prefer to use it.

Unfortunately, this is STILL not supported in upstream SDDM:
https://github.com/sddm/sddm/issues/326
https://github.com/sddm/sddm/issues/346

Just for grins, try kde-plasma.desktop

I was thinking we weren't using the right value for session=...
I had the same problem when setting the cursor until I stumbled upon the
correct value, and I got
kde-plasma.desktop from the sddm.log; however when I switched to that it
then just displayed plasma.desktop
so I'm not sure what is the correct value.

According to the doc, this only comes into play the first time, so my
testing of it was invalid... it appeared to
work because it was being ignored in my case.

Here is another link I found:  https://www.mankier.com/5/sddm.conf

I'll keep looking, but if you do figure out what is going on, please post
here... I'm curious now...

The Theme cursor settings I posted earlier are accurate and do work, if
that is any consolation... ;-)

Thanks for clearing that up. I was just about get strace out to see if I 
could see whether sddm was trying to access /etc/sysconfig/desktop or not.

I can add a +1 to sddm issue #326 if you think that would be helpful.

I guess the kickstart docs need to be updated to say that
xconfig --defaultdesktop=xxx
won't work for sddm. I can add a redhat BZ for that.

Since kickstart doesn't have a command to configure the display manager 
I guess it won't be possible for
xconfig --defaultdesktop=
to be able to do the right thing.

Gerald (and others)

I seem to have found a workaround to make Plasma the default desktop in 
sddm.

I renamed /usr/share/xsessions/plasma.desktop to 
/usr/share/xsessions/0plasma.desktop and Plasma is now offered as the 
default session on the sddm login screen.

Of course, every time the plasma-workspace package is updated 
plasma.desktop will come back, but I can handle that.

Thanks to everyone for their input.

Hello,

I was facing the same problem as mentioned in 
https://lists.fedoraproject.org/archives/list/[e-mail]/th...

and found a solution (sorry for having this topic awakend from the 
sleeping beauty):

in /var/lib/sddm/state.conf is the preselected session set, so use this 
content for xfce as first choice (if you have something like puppet 
running you can enforce this file content):

[Last]
# Name of the session for the last logged-in user.
# This session will be preselected when the login screen appears.
Session=/usr/share/xsessions/xfce.desktop

And the /etc/sysconfig/desktop file is read in /etc/X11/xinit/Xclients
If you add there a line at the top like

STARTXFCE="$(type -p startxfce4)"

and in the following if-conditional :

if [ -f /etc/sysconfig/desktop ]; then

. /etc/sysconfig/desktop
     if [ "$DESKTOP" = XFCE ]; then

PREFERRED="$STARTXFCE"

and then change the "if" before the GNOME  line into "elif"

Kind regards

Sven
