My PC boots faster than my monitor turns on
(discuss.tchncs.de)
THIS WAS THE MEME I WAS ACTUALLY LOOKING FOR!! Thanks!
Fun fact about monitors turning on slowly: did you know Windows has a bluescreen code for that?
The WIN32K_POWER_WATCHDOG_TIMEOUT bug check has a value of 0x0000019C. This indicates that Win32k did not turn the monitor on in a timely manner.
That's right, Windows will panic and throw a bluescreen if your monitors take a little too long to wake up. Had the pleasure of dealing with this suddenly becoming an issue and causing wide bluescreens on wakeup after an update back in mid-2024, on any Surface Dock using DisplayPort with specific Acer monitors.
Woah woah..... is there someplace in the event logs where this would show? Does this mean that you cannot run a windows computer headless?
It gets logged in the event viewer, yeah. That's how I discovered it, on account of the screens not waking up in time to show the actual bluescreen. The users were only reporting that their computers were deleting all their windows when waking up. From their perspective, all they saw was their computer taking a mildly longer time to wake up from deep sleep and then losing their entire session, but what it was actually doing was hard rebooting.
Headless is fine, the bug was specifically triggered when a computer woke up and detected a monitor exists, but the monitor took some unspecified amount of time too long to wake up. It was also fixed at some point, I'm not sure when, but it went on long enough that we swapped dozens of cables because it specifically only happened on the ones using DisplayPort, not HDMI.
Oh shit, this may be the problem I've been having with my laptop dock at work
I hate my monitor for that. Entering the bios is guesswork about when to press a key if I remember what key to press. Also I can't turn it on too early before the PC or it will go to stand by after not receiving a signal for two seconds and then take even longer.
I want a monitor turns on and stays on.
Let me guess, samsung odyssey? Had one of those, never again.
Friend even called me that he has fucked up his pc rebuild - his Samsung monitor was just not waking up because it literally turns off.
I've learned the hard way that there's only one decent Samsung product line - from big appliances to little electronics - and it's their phones (and even those leave questions on privacy).
That's funny, while I still buy Samsung TVs, I hate their phones. So much of what their phones can do is usually locked to only working in Samsung's apps and those are universally dog shit. The phones themselves are also often privacy and user control nightmares.
Granted, there isn't a lot of good choices for phones these days. I'm still running an old LG phone and have been looking outside Android as my next possible solution. But, I also haven't had a reason to upgrade.
Have a Samsung TV and it's by far my least favorite. Turns off at random, takes forever to switch inputs, turns on at random...
As for phones I'm eyeing the Motorola RazrFold, since they're supposedly offering it Graphene-ready
Turn off all of the Energy Saving/Eco Solution crap. It will stop turning off and you will get s brighter inage that doesn't shift in brightness.
You should also switch to Movie mode in the picture settings and set dejudder/deblur (under Motion Clarity) to 0 while you're at it so it doesn't turn everything into 60 fps with fake frames.
All modern monitors are like this now. Dell, HP, Asus...
Doesn't detect input? Instant power off. Now you have to press the menu key every 5 seconds to try and find the input for your PC.
Beyond ridiculous. I have a Dell that's like 15 years old and it stays on for multiple minutes before going into power saving. It's glorious
Typical Samsung product. Good hardware, acceptable build quality/ material selection, horrible software.
On mine you can't even select the input manually, the monitor always cycles through every input. Couldn't find anything on input 2 I just plugged in? Let's do another round of checking all inputs for 10 seconds, and again, and again.... And always finish on the input you started, or turn off if no active input is found.
Software always destroys their products.
Indeed! The biggest requirements for a monitor in my book are that it does not shut off without input, and that it actually turns on when I press the power button or switch. After that (as importance goes), I prefer IPC screens. I don't use OLEDs because of burn-in.
I have a modern Lenovo monitor (2020) that takes longer to wake up than my hp monitor. So annoying.
Edit: aforementioned is from 2011 and is a zr2040w.
The Lenovo monitor is a d22e-20

Those modules, man… they’re the biggest cause of—dare I say it?—bloat in the kernel.
For the few people here who may not know about it: there’s a utility called modprobe-db that watches what kernel modules get loaded at runtime, and can generate a kernel build config file accordingly. There’s even an ArchWiki article about it. You need to keep it around for a while (e.g. several weeks or months) so it can get a proper sample of the modules you use; that way, your kernel can have all the modules you need (ask me how I know). If you do it right, however, you can slim down your compile time significantly.
Does that mean you need to fiddle with modules, because you plug in a new USB-device you haven’t used before?
I'll ask! How do you know? Lol
All jokes aside, I think this might really help me with a side project I've been working on. Ive been trying to get full disk encryption working on a NanoPi R6S running NixOS. The issue that im having is that im not sure exactly what modules I need in the initrd. When I boot, there is no output on the display after systemd-boot shows.
The manufacturer puts out a version of Ubuntu thats works flawlessly so I know its possible. But I'll pass on the snaps and id rather not use uboot. System is working with edk2 and nixos.
Long story short, will this software allow me to figure out what is running in the manufacturer's kernel and port it over?
How do you know?
Zoom not having working audio—discovered right before a job interview 💀
But yeah, I bet it would work! Just make sure you run modprobe-db with the manufacturer’s kernel long enough to run all the software you’ll actually use, so it can record the modules you need.
Of course, make sure you read up on it with that ArchWiki article and take a look at the source code to be sure (it’s basically a simple shell script), but from what I understand it should do what you need.
Well if it was for a tech job im sure you could've shown off some troubleshooting skills haha
And the ArchWiki link is perfect. Ill read up on that and ensure I'm using it correctly. Thank you very much for the pointer kind stranger! :)

I feel like the boot time is almost entirely uefi ram timing shenanigans these days
Gentoo is GOAT. I am also glad that Arch exists though. Both have excellent wikis, good knowledgeable communities, lots of configuration options. In terms of pure speed, it is hard to beat a build it all from source as per your own custom USE flags setup like in Gentoo.
Speaking as a Gentoo user here: Gentoo is more capable, but Arch has better documentation.
What's this "boot" of which you speak?
Do people really turn their machines off these days?
You've got to reboot after kernel updates, otherwise it can't load new modules. I've been confused at least twice why something didn't load until.I remembered the reboot.
I think the command "systemctl kexec" would like to have a word. Great command to know if you have a VM on a system you dont manage / share with others.
I didn't know about that one.
I hope it helps you someday! :)
Gtk what replaced 'telinit 3'
Yes, I'm not wasting my hardware life and electricity for no gain.
Thermal cycling
On the other hand, if the computer is powered on, there's wear and tear on the moving parts (mostly just fans now), and components like capacitors have a limited lifespan. These tend to be the first components that fail anyway, and I've always thought it odd to further reduce the lifespan of these components with the hope to extend the lifespan of what's already the most reliable parts of the computer.
Now, with modern computers that sip power at idle but can consume hundreds of watts under load, the difference in temperature at idle and load is much greater than room temperature (off) and idle, so even if I was worried about thermal cycling I'd still be inclined to turn the computer off when it's not needed because when it's off there will be no big temperature swings. Granted, with Linux when my PC isn't being used it pretty much just sits at a constant and steady idle... but Windows on the other hand...
Combined with the added electricity cost of not running the computer when it's not needed, not leaving the machine running all the time is the obvious choice.
Its arguable that machines last longer staying at temp.
I use my machines enough that having to boot when I need it is just time wasting.
yes
Yup. My entire PC desk (monitor, PC, 2+1 speakers) draw 7W when the PC is turned off (old speakers draw power when off for some reason). For comparison: My NUC server draws 7W white turned on, doing useful work. This infuriates me, so I got a zigbee power switch and shut the PC desk completely off when I'm not home.
If 7W for nothing pisses me off, you're damn straight an idle or sleeping PC will too!
