If it's not a server then it's getting turned off when I'm not using it

Yes like once a week reboot

Rebooting is a good idea from time to time to ensure any new updates have taken fully and that old system drivers haven't lasted and continued to run.

For example, one time I installed an XOrg update but didn't reboot because my distro's updater didn't recommend it. And so I was very confused when I actually did reboot and graphics were borked. It took me a while to track down that the update - which I'd forgotten about - hadn't been compatible with my graphics driver and I'd been using the previous working version until then.

It's supposedly possible to restart / reload all software without rebooting, but it's a royal pain in the [proverbial] when it's deep in the system, and it's far easier to just reboot.

And if you're gonna reboot anyway, you could time that nicely for before you'd be about to stop using the computer for a while. Let it reboot first to make sure everything seems OK with any updates that might have been applied. When that works, you're at a fresh slate with no programs open, so you can then turn it off.

(And if it hasn't worked, you can roll back with something like Timeshift or whatever your distro provides, check that works and save the investigation for when you have time.)

Not shut down, restart.

But with such fast boot times, I just turn it off when I'm not using it.

i usually restart pretty often bc I like to keep it updated

I'm using an arch based distro so I get kernel and driver updates pretty frequently that need a reboot to load. There is some weird thing I haven't found a fix for yet, where sometimes a warm reboot forgets half my RAM (likely something to do with MCR)... but a cold start works fine. So I shutdown and restart and all is well. Once a week maybe?

Every day before I go to work. For 10 hours at least.

Hibernation is underrated. If you don't want to risk losing stuff you have open but want 0 energy draw, hibernation is great. As a bonus, you can store your swap file in an encrypted partition to prevent attacks possible with normal sleep mode.

I have my sleep option set to automatically switch to hibernation if it's been asleep for 3 hours.

Only when I update. My PC plays brown noise to my DAC that's connected to an amp that's connected to my speakers that I need to sleep.

I do because bazzite consistently kernel panics for me roughly every third wake-from-sleep with nothing in the logs.

If you're specifically asking because of memory use, there is no need. Memory management in Linux is extremely efficient, and since everything is a process, a properly killed process doesn't block reclaim of that memory as you see a lot in Windows. You may see your "free" memory as being low, but that's kind of a misnomer as you should be paying attention to claimed vs unclaimed/cached memory, which will be "recycled" into other processes that request it. If you run into memory issues on Linux or BSD, you'll know it.

That being said, if your machine isn't suspending or cleeping, then you're just wearing your components out by leaving them on 24/7, so shutting down or suspending would be good practice to extend the general lifespan of your machine.

I power off if i wont be use

I shut down desktops before bed time. SSD cold boot is nothing. Steam Deck sleeps sometimes, useful for obvious reasons.

You can do whatever you want, just reboot after updates.

No, never. Unless I have to leave for an extended period of time or I know there's going to be a planned power outage.

I grew up in the era of. PCs take forever to boot and sleep is good enough that when I turn it back on it’s still alive.

Laptop Sleep, desktop depends on when I use it last.

The answer, even with other OS's, it's typically yes you should shut it down. I always use sleep, but if I know that I don't have anything important open, I try to shut down

I use hibernate (suspend-to-disk). This way I can save power and have all the apps open when I login after resume from disk. Full reboot happen after important security or major updates.

My swap volume is 150% the size of my RAM so that there is never a situation where I cannot do this. The only program I close before systemctl hibernate is my browser. That saves sone wear on the SSD.

Hibernate works surprisingly well on Linux. Even with LUKS encryption you can make it work.

I shutdown every night because there's a bug where it won't wake up from sleep like 70% of the time. Easier to just shutdown than gamble and get annoyed.

It cold boots in like 20 seconds if there were no updates, so not a huge deal.

Rarely. My PC works fine when it's left on and that's good enough for me! It gets rebooted after updates but only ever switched off when I go away for a few days.

If I’m not home and on the computer, it’s off. That means sleep and work time mainly, but also if I’m going out with friends for a few hours.

I only do system upgrades every so often, normally based off hearing some new feature in a program I want. When I do, that usually includes a kernel update and it asks me to restart.

Yes I always shutdown my laptop/desktop. They boot so quickly I see no need to use sleep. The only time I use sleep is when I'm streaming with Sunshine but half the time WOL doesn't work anyway. 🤷‍♂️

My Windows work laptop on the other hand...

I can fly to Costa Rica, get some coffee beans, fly back home, grind those beans, make a fresh espresso, and then maybe it will have finished booting from shutdown.

I'll be the odd one out, as a relatively new Linux gamer. I almost never shut it down unless I want OS updates. Weeks without an intentional shutdown usually.

I treat it more like a phone than I do a TV or radio like I saw other people mentioning. Always on, as I left it, running whatever it was running. Screen turns off after 30 minutes of course.

I don't pay for power, so that's not really a concern for me, and I use it frequently enough when home that most of my time involves the desktop in some way.

I put my desktop and laptop to sleep when I'm not home when I'm sleeping.

Laptop sleeps all the time. "Shutdown" when the battery runs out. PC is basically never shutdown. <-- Gets rebooted every now and then. Server is basically never shutdown. <-- Gets rebooted every now and then.

For example, maybe once a week or once a month?

Generally-speaking

and there are some specific situations where this doesn't apply

your computer cannot start using a new kernel unless you reboot the thing, and there will be kernel updates. And some of those are security updates. So, yeah, you should reboot at some point.

It's not really a "your computer will perform more-slowly if you don't reboot occasionally" concern, though.

I mostly shut down my machine and sleep it less often. I feel being off will use a bit less energy even if sleep is almost the same and is a bit more secure even though the sleeping machine should have the network adapter shutdown. I doubt it makes that much of a difference but it used to in the past and im a creature of habit. I can't say why I sleep it honestly I just do sometimes.

I give it a reboot if I'm not using it and there has been a kernal update. Sometimes games launched in Lutris breaks alt tabbing and I reboot to fix that.

I'm with the once-a-weekers

yep, its how it updates to the latest container image.
