Laptop Power Management - Issues w/ TLP

Hi!

I'm new to the forums and I'm also new to Arch Linux. I recently installed it on my laptop. As recommended, I installed TLP on it for power management.

I did a reboot after the install. This is where the fun begins...

On AC, I'd be able to get through the log in screen, however, my internet would not work. Pinging a website would not work at all.

On battery life, I can't get pass the log in screen. At times, I'd be able to put in my username and password to get on, but it would still freeze/hang.

I looked through TLP's documentation and found this:
https://github.com/linrunner/TLP/issues/125

...which somewhat resembles my problem. I tried the solution, but it did not work.

I'm a newbie on Arch. Reply with commands that I'd be able to execute to give you more information. At this point, I really have no clue what else to do.

Thanks mates!

Re: Laptop Power Management - Issues w/ TLP

Welcome to the forums!
The bug report mentions that the issue arises with hybrid gpu systems. Do you have such a system? Are you using bumblebee then?
Did you use the RUNTIME_PM_BLACKLIST option with the correct BusId?


I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do.  (Gune | Titan A.E.)

Re: Laptop Power Management - Issues w/ TLP

Hi!

Thanks for the quick reply!

I'm not quite sure if I have "hybrid graphics."

Here's what I got:

$ lspci -vnn | grep VGA -A 12

No, I'm not using "Bumblebee" and I haven't really played around with the configuration other than changing the RUNTIME_PM_ALL=0.

Thanks for the reply once again!

Re: Laptop Power Management - Issues w/ TLP

First: you should use code tags to post output of commands.

The person who reported the bug you linked had an integrated intel gpu and a discrete nvidia gpu. The power management for the discrete nvidia card was causing the trouble.
You seem to have an amd system so your problem might be a different one. Especially because the suggested solution didn't work.

Did you check that it is really tlp which causes the trouble?(e.g. by disabling tlp)
Look through you log file(or post them here) if there are erros. journalctl and xorg logs would be the ones to look at first.

Also what display manager, DE/WM are you using?
When you say your internet did not work do you mean your wifi module does not work?

Re: Laptop Power Management - Issues w/ TLP

The problem is very easy to reproduce. As described on the first post, it's exactly that. For me to even get on the Internet, I needed to uninstall TLP and reboot.

My display manager is OpenBox and my DE is LXDE.

I'm not sure if it's my WiFi module. All I know is that when I have TLP, it would not work at all.
