Adding a command at boot

emilo

Hi, (new Solus user here)
I want add a command to control gpu power when computer start, in order to not let the computer self destruct. Command is 'nvidia-smi -i 0 -pl 80', and guess I want it to run about when the graphics system loads. I have done this before with a simple crontab, but as I understand cron is not supported in Solus. So how do I do it?

Thanks. How do I do that?

There are lots of howto's and guides about systemd units and timers, this is not Solus specific. For your simple use case you may start here: https://www.linode.com/docs/quick-answers/linux/start-service-at-boot/

I'm not familiar with nvidia-smi command, but why schedule it if it needs to be run only once on DE startup? Wouldn't it be enough to simply add it to autostarted applications?

If the command does need to be scheduled, then a new systemd service should be created.

just Yes I want to add it to 'autostarted applications', if it can run the good command (as root). If the command is given when computer starts all is fine. How do I do that?

Thanks, but I do not understand much of this. Do I really need to write a custom script for this to work?
Will a script file with this work?

@reboot
 sleep 20
 nvidia-smi -i 0 -pl 80

With cron it is very simple to just add a command. Is it a way to install Cron in Solus?

emilo Is it a way to install Cron in Solus?

Cron isn't available in Solus. There's no easy way to install it.

Edit: Systemd monster is the only available scheduling tool in Solus. Some skills are needed to deal with it.

Creating a new systemd service requires much more then just a working shell script.

For me, it doesn't worth to create and manage new systemd service, if the command really must be run only once on DE startup. Just add a new "application" to Autostart list, and in the Command field, instead of an application name, simply write:

sleep 20 && nvidia-smi -i 0 -pl 80

The command will be executed each time a DE is started up.

@emilo
why not try add something to etc/rc.local? Not sure if its best practice though.

I use it to disable some wakeup settings and killing bluetooth
