I'd like to see you folks support Ubuntu on a Rasperry Pi

Set Headless Resolution:
sudo nano /boot/config.txt
Copy below to bottom of file, save and exit
# Set headless video resolution
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=47
# (above is 1440x900@60Hz)
# hdmi_mode=16 (1024x768@60Hz)
# hdmi_mode=39 (1360x768@60Hz)
If you have a Pi 3B+, we add 1GB to the swapfile. This seems to resolve memory exhaustion issues over time. I've been adding this to Pi 4 units as well, just in case.
sudo nano /etc/dphys-swapfile
CONF_SWAPSIZE=1024
(Not mine, some copy and paste I found online that works for me)
Thank you for sharing this!
Anything else you are doing? Its refusing to display for me still with these settings.
is there any update on that topic? I also have a few pi4 with ubuntu 20.04.02 LTS 64bit and connectwise on them... but it seams that I only get blank screen. Even doh fb test script gives me out following output:
gcc not found. Installing gcc.
Installed gcc successfully.

Uninstalling gcc.

No, but please open a case with the support and refer to SCP-37140
I have been pushing this but getting nowhere. Its become a real pain.
I've followed the instructions and successfully installed the agent on them, however I have a couple that worked for a few days then have been offline ever since. I can remote to them via VNC and i've re-run the script, but still offline, any ideas to try? Thanks
We would also find this useful, we have a fleet of PIs on our production floor and it would be great to be able to do remote support.
We've started to have the need to do this and we are also getting a blank screen on connect.
Just wanted to add something here to this. I got this to work today. I had to open a case with CW they did not directly hepp me but they did tell me I needed to disable wayland. In short you have to disable WAYLAND. To do this on the Raspberry Pi you need to do the following after it is installed. I was running Raspberry Pi OS in full disclosure.
sudo nano /etc/lightdm/lightdm.conf
uncomment the line that says #xserver-command=X
then make it xserver-command=X -core
sudo systemctl restart lightdm
sudo systemctl restart [CWSERVICENAME]
It worked for me!
Martin,
Specifically, what screen options? For headless.
