Cannot find the default environment

[EddieA]

I’m guessing that this is just a simple configuration issue, but I’m not sure what.

I created a new Slackware 14.2 VM and installed nomachine_5.1.42_1_x86_64. From my Windows system I was able to connect to this when it was running the installed KDE, 4.14.21 without any problems.

I then updated the KDE to 5_16.07 using Alien Bob’s repositories.  As part of that update, it was necessary to run xwmconfig to re-configure the system wide Window Manger.  For KDE4 the selection is xinitrc.kde.  But for KDE5, this is now xinitrc.plasma.

Following this, I can run startx locally and KDE starts correctly, but trying to connect via NX I get the “Cannot Find the Default Environment” error.

What configuration changes do I need to make.

Cheers.

This post can help you probably:

Hi.

It can be caused by Wayland. We have been able to reproduce a similar problem, but to be sure can you run debug, reproduce problem and send us logs from server side? You can send them to forum[at]nomachine[dot]com or attach them here (size is restricted). Instructions about debug and collecting logs you can find there: https://www.nomachine.com/DT04M00076. Please show us or send also X processes when you are logged to desktop (ps -Af |grep Xorg).

As a workaround you can try to log to the Plasma (failsafe) or Xfce Session. If that won’t help – open node configuration file (/usr/NX/etc/node.cfg) and add line DefaultDesktopCommand "/usr/bin/startxfce4", save file and restart nxserver (sudo /usr/NX/bin/nxserver --restart). Then you should be able to start new session.

Sorry.  Tried all the values for `PhysicalDesktopMode and it didn’t make any difference.

So next, I turned on logging.  Logs attached.

On investigating the differences between the old xinitrc and the new, gives this diff:

29c29
<     ck-launch-session dbus-launch –sh-syntax –exit-with-session startkde
—
>     ck-launch-session startkde
31c31
<     dbus-launch –sh-syntax –exit-with-session startkde
—
>     startkde

So the method of launching KDE has changed between 4 and 5.

Cheers.

Ha.  Didn’t see that last post while I was composing mine.

Here’s the other piece of information you asked for, when I’m running KDE at the VMWare console:

root      7029  7028  1 19:11 tty7     00:00:02 /usr/libexec/Xorg :0 -auth /home/eddie/.serverauth.7012
eddie     7538  7532  0 19:13 pts/2    00:00:00 grep Xorg

How do I select the Plamsa (failsafe).

Cheers.

We didn’t get those logs. Can you send them on to forum[at]nomachine[dot]com?

Unfortunately I won’t be able to send them for a few days.

My firewall/gateway/router server died over the weekend and I had to re-purpose my ESXi server to maintain my internet connectivity.  That means I won’t have any access to the VMs until I get a replacement board up and running.

 

Cheers.

 

[EddieA]

Logs sent.

 

Sorry about the delay in sending these.

 

Cheers.

At the moment we do not support KDE5 Plasma on Slackware. So for a workaround use xfce4 (add line DefaultDesktopCommand “/usr/bin/startxfce4” to /usr/NX/etc/node.cfg) or downgrade KDE.
