DietPi v6.33.3 : 10:05 - Mon 11/30/2020
Device model : RPi 4 Model B (armv7l)
i’ve installed xfce and mate at separate times and when accessing on lan via nomachine i get the message:
" Ooops! Cannot find the default environment. Please contact your system administrator."
when i have lxde installed, the desktop shows up fine when accessing via nomachine.
is there some config specifics one needs to add/edit in order to get mate or xfce accessible via nomachine? like
starting their respective desktop manager when accessing or something?
many thanks for your message. I tried to replicate your issue. But for me this is working well. I installed Xfce from dietpi-software and NoMachine for Raspberry (armhf) - nomachine_6.12.3_5_armhf.deb. I had no issues to connect.
and i have no issue with lxde & nomachine as previously mentioned.
i’m pretty sure its me/my config, just trying to narrow where this point of failure is.
this particular rpi had dietpi reinstalled this week so its a fairly clean install. it’s the 32bit version and nomachine was auto installed via dietpi.txt.
Maybe you can check if Xfce is starting correctly as normal Desktop?
well that is a good question. i’ll check that and get back to you. thanks!
i uninstalled and reinstalled both xfce4 & noMachine.
i connected a monitor to it. xfce4 was running and i logged into the xfce4 desktop via noMachine with no issues. so far so good.
if i shutdown, disconnect the monitor, boot going headless, cannot access desktop via noMachine. i get that message about
“Cannot find the default environment. …”
the /var/log/Xorg.0.log had one of these message lines:
(EE) Fatal server error:
(EE) no screens found (EE)
i uncommented this in /boot/config.txt
hdmi_ignore_hotplug=1
i edited these as that's the rez i want with noMachine from a laptop:
framebuffer_width=1440
framebuffer_height=900
i did see an option for headless in dietpi-config under display resolution but i had already edited the /boot/config.txt. i assume it does the same thing?
i don’t understand why lxde worked as headless but xfce4 wouldn’t without the /boot/config.txt “hdmi_ignore_hotplug=1” edit.
anyways, it’s working now. thanks for your time and help!!! as always you folks got me running in no time!
**note: not related to my original post, but i noticed when executing the ~/Desktop/.desktop icons they timeout with error. the same dietpi-.desktop files that they are linked to in /usr/share/applications/diet-*.desktop, when executing from main menu Applications->System, they execute as expected. no biggie.
