Disabled cooling and GPU overheating

TorSkiZ · 07-02-2023, 10:05 AM

I have a problem where the monitor randomly goes into sleep mode due to a lack of input while using Linux. This occurs in both the LiveCD environment necessary for installing Gentoo Linux (command line) and in GParted (desktop). In Windows, I don't experience this issue. It's worth noting that previously, when I had a GTX 980 Ti graphics card, I also had this problem with GParted. If necessary, I can provide the required logs.

My current specifications:

Code:

CPU: Intel Core i5-11400F
RAM: 2x16GB 3600MHz CL18
GPU: NVIDIA GeForce RTX 3060 Ti

Thank you in advance for any assistance you can provide.

Hello, TorSkiZ & welcome to LQ.

Does your box resume normal function if, for example, you tap the spacebar? Or is a reboot required?

If spacebar restores normal function, linux is working as designed. Do not adjust anything. If you need to reboot, then it's a problem.

In the early days of pcs, there was no screensavers. So the folks in accounts would have the numbers and columns 'burned on' to their monitors because it was on all day, and others would have their software imaged too. Even the linux agetty consoles have a built in screensaver.

Thank you for such a prompt response.

A reboot is required using the button on the computer.

Pressing all possible keys on the keyboard doesn't help.

In the meantime, I checked a few things. If I manage to create a user password and start the SSH server, it keeps running even when the screen goes off. Similarly, if I blindly enter the command "fdisk -l", the LED light on my USB drive blinks, indicating that it's in use.

I also suspect that it may be an issue with GPU overheating. Here's why I think so:
- When I start the computer that has been off for a few hours, the time it takes for the screen to turn off is always several times longer than immediately after a restart (when the computer is already warmed up).
- As soon as the screen turned off, I restarted the computer and booted into Windows, where I have the MSI Afterburner program to control my graphics card parameters. I was surprised to see that immediately after booting, the fans on the card were running at full speed, and in the program, I saw a temperature reading of over 80°C.
- It's also worth noting that in my case, the GPU fans don't spin at all when using Linux.

That's your problem then. But I'm not much use to you. It's ~10 years since I had a Nvidia card, and I don't even know your desktop.

I'd check

your installed nvidia utilities
Any others you can install
The desktop power manager

And if someone doesn't post, Edit the subject on post #1 to be something like "Nvidia Cooling Issue (Random loss of output on the GPU)."

And try search engines, as it's all happened before.

I have an i5-11400, no K, and no NVidia. When I have it actively doing something, the OEM CPU fan is almost constantly changing speed up & down. If you're using the OEM CPU cooler, I'd try a better one.

As for sleep mode, Xorg supports 'Option "DPMS" "off"' in 'Section "Monitor"' in /etc/X11/xorg.con*. Give it a try in the installed system. I don't know whether you could make it work in a live installer, unless you can remaster or edit your installation media.

I have a double-tower air cooling system. The fan curve is set up in such a way that the fans don't spin at idle and their speed increases linearly to 100% at 75°C. However, I don't think it has any significant impact. The CPU cooling doesn't contribute as much to the graphics card cooling as dedicated GPU cooling does.

The issue doesn't only occur in the graphical environment but also in the console, so I don't think the problem lies here.

I installed a new graphics card (MSI GeForce RTX 3070 VENTUS 3X OC) and the issue is not present. The fans start spinning immediately from the boot-up of the Gentoo installation environment. After several minutes, the problem of no signal to the monitor doesn't occur. The previous card model was the GIGABYTE GeForce RTX 3060 Ti EAGLE OC 8G (rev. 1.0). Since the problem only disappeared after replacing the card, I believe there was something wrong with it.

The issue is resolved in my case, although not entirely, as it required a new graphics card.

Kernel cmdline option consoleblank=0 in Grub stanzas keeps my vttys alive fulltime.
