The only display manager that will work currently is kdm with LXDE as the window manager…

#2

Hi
Have you disabled wayland in gdm?


cat /etc/gdm/custom.conf

....
WaylandEnable=false
....
#3

Yes I did that as well, still no login screen.

#4

Hi
Do you think it’s fallout (as per your other thread) of still missing files in /etc? Might have to look at forcing install of packages…

#5

OK, I have quite meticulously reinstalled packages, everything that I could see related to display operations that listed file in /etc

With the display manager set to GDM, and Wayland disabled; no login screen.

Hi
This doesn’t look good…


xf86OpenConsole: Cannot open virtual console 7 (Permission denied)

And your default target is graphical?

#7

From my /etc/systemd/system


lrwxrwxrwx  1 root root   40 Oct  3 01:10 default.target -> /usr/lib/systemd/system/runlevel5.target

And a /usr/lib/systemd/system check:


-rw-r--r--  1 root root   558 Sep  2 17:20 graphical.target
lrwxrwxrwx  1 root root    16 Sep  2 17:20 runlevel5.target -> graphical.target
#8

A general comment…
I see you’re running LXDE.
You should know that although LXDE is still an officially supported Desktop on openSUSE, all the LXDE developers moved over to LXQt several years ago.
Ever since then, LXDE has been in a kind of “maintenance mode” but without a proper, full Project support.

I highly recommend you instead install LXQt.
On my LXQt machines, it looks like the default DM is lightdm although xdm is also installed.

TSU

#9

Thanks, maybe later. As far as I am concerned, I am kind of in a ‘maintenance mode’ right now. Once I can get my system back to a degree of normal, I can try the other selections.

#10

GDM still refuses to start.

The only combination that currently works is


/etc/alternatives # ls -al d*
lrwxrwxrwx 1 root root 24 Oct  5 21:43 dbus-launch -> /usr/bin/dbus-launch.x11
lrwxrwxrwx 1 root root 32 Oct  8 18:36 default-displaymanager -> /usr/lib/X11/displaymanagers/kdm
lrwxrwxrwx 1 root root 41 Oct  7 10:57 default-waylandsession.desktop -> /usr/share/wayland-sessions/gnome.desktop
lrwxrwxrwx 1 root root 33 Oct  8 18:37 default-xsession.desktop -> /usr/share/xsessions/lxde.desktop

I get a login menu and then selecting the only really stable environment, LXDE; even after the session loads I still see the message:


Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: Failed to activate service 'org.freedesktop.PolicyKit1': timed out (service_start_timeout=25000ms)

In /etc/gdm/custom.conf


WaylandEnable=false

In /etc/sysconfig/displaymanager, the only pertinent enabled parameter now is


DISPLAYMANAGER_XSERVER=X.x11-video-nvidiaG05

In /etc/sysconfig/windowmanager


DEFAULT_WM="default"

I have manually went through and reinstalled multiple packages, essentially anything that has files listed as resident in /etc.

#11

Hi
I’m using the nvidia driver installed the hard way, I see;


DISPLAYMANAGER_XSERVER="Xorg"
#12

Setting the display manager as above allows LXQt to start successfully.

IceWM and LXDE (still with the previous stated error) start.

MATE will start but has issue with the menus and is overall sluggish.

Plasma starts but there are no objects, menus, or other options available on the desktop.

Also, if


lrwxrwxrwx 1 root root 32 Oct  9 11:13 default-displaymanager -> /usr/lib/X11/displaymanagers/kdm

is any different, then I get a very generic looking login screen, with no options, just a field for the user and password.

#13

It’s my understanding the sysconfig settings for DISPLAYMANAGER have no effect since the switch to using alternatives to select the DM.
Although the same should be true of the WINDOWMANAGER, from my personal testing the results are less clear, and not consistent. The recommendation is to use alternatives to configure the WM like the DM.

TSU

#14

With respect to the previous post, from the current /etc/sysconfig/windomanager


# Here you can set the default window manager (kde, fvwm, ...)
# changes here require at least a re-login.
#
# This value is deprecated and not read by most display managers.
# Use 'update-alternatives --config default-xsession.desktop' for configuration instead.


DEFAULT_WM="default"

so I # this out.

In /etc/sysconfig/displaymanager I have


DISPLAYMANAGER_XSERVER="Xorg"

Setting /etc/alternatives # to


lrwxrwxrwx 1 root root 32 Oct  9 23:45 default-displaymanager -> /usr/lib/X11/displaymanagers/gdm
lrwxrwxrwx 1 root root 41 Oct  7 10:57 default-waylandsession.desktop -> /usr/share/wayland-sessions/gnome.desktop
lrwxrwxrwx 1 root root 34 Oct  9 22:42 default-xsession.desktop -> /usr/share/xsessions/gnome.desktop

I still get the grey, no options login, but this time, Plasma actually starts and seem to work somewhat normally.

~/.xsession_errors has some interesting lines

When you use a particular DE, there are recommended DMs…
In particular, some DMs work better with the Qt framework (lightdm, kdm) and some with Gtk (Gnome base) (gdm)
DEs that are built on Qt are KDE-Plasma, LXQt
DEs that are built on Gtk are Gnome, XFCE, and although LXDE doesn’t specify, openSUSE implementations have been built on Gnome Base by default.
Other DMs (and related WMs) usually don’t specify but I generally test them only with a DE running Gnome base.

If you run a DE with a not recommended DM, anything is possible… Maybe things won’t work, maybe you’ll see funny things, maybe there won’t be any diff.
Reason why I mention this is because when you run a DE, you probably aren’t advised to switch between kdm and gdm as example.

How are you setting alternatives?
If not already, you should use the “update-alternatives” command with the “–config” option, eg the following

# update-alternatives --config default-displaymanager 
There are 3 choices for the alternative default-displaymanager (providing /usr/lib/X11/displaymanagers/default-displaymanager).


  Selection    Path                                  Priority   Status

  2            /usr/lib/X11/displaymanagers/lightdm   15        manual mode
  3            /usr/lib/X11/displaymanagers/xdm       10        manual mode

Forgot to mention, if you switch DMs, don’t forget to switch to an appropriate WM as well, it doesn’t happen automatically.

TSU

#18

With respect to how I am changing DM and WM, I had been just removing the links and creating new ones in /etc/alternatives.

So, I did it the correct way:


# update-alternatives --config default-displaymanager 
There are 5 choices for the alternative default-displaymanager (providing /usr/lib/X11/displaymanagers/default-displaymanager).


  Selection    Path                                  Priority   Status

  1            /usr/lib/X11/displaymanagers/console   5         manual mode
  2            /usr/lib/X11/displaymanagers/gdm       25        manual mode
  3            /usr/lib/X11/displaymanagers/kdm       15        manual mode
  4            /usr/lib/X11/displaymanagers/lightdm   15        manual mode
  5            /usr/lib/X11/displaymanagers/xdm       10        manual mode

Press <enter> to keep the current choice
[li], or type selection number: [/CODE}[/li]

Chose ‘0’ for gdm auto and


# update-alternatives --config default-xsession.desktop
There are 9 choices for the alternative default-xsession.desktop (providing /usr/share/xsessions/default.desktop).

and chose '6' for mate.

Same no-option login, and the session defaulted to Plasma.  It did that for any DM choice other that kdm.

I also tried DM option 2, manual gdm, with WM of mate; which again booted to Plasma; here is the xsession-errors

#19

Reinstalled the gpg2, polkit, gconf-polkit, polkit-gnome, polkit-kde-agent-5 packages; and now with DM=gdm and WM=mate; I still get the generic, no-options login screen but the MATE session comes up with the MATE Applications menu showing its items.

However, still some issues in xsession-errors

And if it is related, when I try to access a connected USB drive from the ‘Places’ menu, I get a popup


Unable to mount usbhdd
Not authorized to perform operation (polkit authority not available and caller is not uid 0)

Launching browsers no longer ask for a keyring password.

#20

An additional observation, any ‘pkaction’ command times out


# pkaction |grep login
Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: Failed to activate service 'org.freedesktop.PolicyKit1': timed out (service_start_timeout=25000ms)

and also

This is with DM=gdm and WM=mate.session; booted with MATE running as the desktop. I am assuming that the ‘Service’ parameter is why I see just the no-option login screen.
