bbswitch VS throttled

> How did you "power down" your nvidia card?

First I made sure X was working the way I wanted with Intel graphics. There are a handful of ways to do hybrid graphics on Linux, depending on what you want to be able to do, and how old your hardware is. The Arch wiki has some pretty good guides [1] that are helpful even if you're using a different system.

bbswitch seems to work on my system, and the interface is really simple [2]. But there's also this page on the acpi-call thing [3], which suggests that bbswitch is old and unmaintained and that newer systems do something different. From a quick scan, it looks like the Arch wiki also mentions this approach.

As far as drivers go, I know everyone likes to dump on Nvidia for their closed source mess, but in every system I've used with Nvidia hardware (desktops and laptops), I've found that the Nvidia drivers have universally been more reliable than nouveau, so that's what I use.

Not sure if you'd want to on a new computer, but you could always try to repaste and undervolt (which is enabled on tigerlake-H processors!). If you don't need to use your DGPU often, you can try to disable it with BBSwitch.

Google tells me, for ubuntu, bbswitch can be used to turn off gpu. Here's the link to its github page. I read the README file, but I'm still new to linux and i couldn't understand the following :

I think what you're looking for is bbswitch. I don't know which Optimus method you're using, but optimus-manager has bindings for it. For example. here is my config that turns it off by default if on batter power at boot:

Try using bbswitch (you can configure it to exclusively use intel graphics)

Yes i know it sounds wild but I need to be able to focus on my programming tasks. I run linux on my system and with throttled installed, it gets noisy and i'm tired of it. I'm not a gamer but I use win10 and win11 VMs and compile source code and just every day tasks spin up this fan. Before I installed throttled ( https://github.com/erpalma/throttled ) it was out of control. I haven HP 840 G5 that hardly even spins up. I got this because i had the same one for work and noticed it never bothered me. I have compared some compile times on the i5 and the i7 and even my desktop, they are all about the same so I dont see why I should care about having an i7. Im willing to buy a new mobo with the i5 8250 and just use that. i bought the dual heatsink fan and waiting for that to arrive so i'll install that first. But can anyone else share their experience with an i5 vs i7 and fan noise?

I have a T480 with an i7-8650U and I am a little confused undervolting using throttled

It's the reverse. For some reason, the embedded controller (EC) on the T480 (and other later Intel Thinkpads) is aggressive with regards to throttling the CPU clock speed even when the temperature isn't that high. To solve this, someone made a program called throttled https://github.com/erpalma/throttled to fix the issue.

Planning to install Arch (EndeavourOS) on it. In the arch wiki and these forums, thermal throttling is mentioned per this post - https://www.reddit.com/r/thinkpad/comments/870u0a/t480s_linux_throttling_bug/. However this is 5yr old. Is throttling still an issue? And do you need to install throttled (https://github.com/erpalma/throttled) ?

Thermal throttling can be tweaked through throttled.

The machine throttles, under (only) Linux, when too law a CPU temperature is reached. Lenovo promised for months to fix this and then announced that it would not, after all, fix it. But the community came to the rescue.

The only thing with the X1C series though is that the thermals straight-up sucks; the laptop out of the box gets really hot really quick and throttles immediately. The first thing I did when I got it was undervolting the CPU with throttled, which helped a lot and increased my battery life significantly too. The fan basically only comes on under pretty heavy load now; before it sounded like it was about to achieve liftoff at about 20% cpu load.
