systemd service of vnc restore

[lavanya tech]

Hi,

Can anyone here suggest me how to restore  vncsessions to current state after its lost.

I currently start vncsessions  via systemd

systemctl start vncserver@ :displaynumber

I look forward to your response.

Thanks,

lavanya

What do you mean by restoring vncsessions? Starting it again when it has
terminated?

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?

Rebooting a server will terminate all process on that server, so those
are permanently gone. The users will need to restart things.

As for the vnc services, did you configure them to be started on boot by
doing "sudo systemctl enable" on them?

I'm not aware of anything that can do this on a process level or session
level, no. You'll likely need to look at virtual machines for an ability
to suspend and resume things over a hardware reboot.
