Acer Swift 3 - battery issues - add Kernel parameters

Support
1

linux518 does resolve the high CPU usage.
Still, Swift 3 is supposed to sport quite a good battery lasting a couple of hours if not more.

The widget/indicator says: remaining time 13 hours, 17 hours, 5 hours etc. It keeps changing, unlike my old Dell where it is stable.

As suggested by bogdancovaciu, I should make modifications to the Kernel parametres.

e.g.
https://wiki.archlinux.org/title/Acer_Swift_5#Kernel_modules_parameters

That seems to mean task.

Am I supposed to find swift3.conf? Should I follow the steps that apply for Swift 5?

/etc/modprobe.d/swift5.conf

options snd-intel-dspcfg dsp_driver=1
options snd-hda-intel model=dell-headset-multi
options snd-hda-intel power_save=1

Hi @korben,

AFAIK by default that directory is empty. mine only has a file created by mwhd in it.

According to me, that means you’ll have to create the file yourself. To do so, open a terminal and run:

sudo nano /etc/modprobe.d/swift5.conf

Insert the following lines:

options snd-intel-dspcfg dsp_driver=1
options snd-hda-intel model=dell-headset-multi
options snd-hda-intel power_save=1

Save, Ctrl+O → Y, and Exit, Ctrl+Y

Then restart to see if it worked.

Hope it helps!

Edit:

For more, see

I have created the file however I cannot exit CMD…

ctrl+ O and then Y?

4

Ctrl + O saves it, and if it asks Y confirms it.
Then Ctrl+X exits the nano editor.
Then you can reboot.

Doesn’t work here. The window won’t close at all. The file is there, the peremetres are there.

I forcefully closed the window.
Rebooted.
Got the system working.
How can I tell if it’s A-OK?

6

Chances are it hasn’t been saved, so not applied. To check, run the following and provide the output, please:

sudo cat /etc/modprobe.d/swift5.conf
7

nano is very self descriptive
It’s literally all written in the bottom two rows
nearly every important command is a shortcut consisting of pressing CTRL and a letter

^stands for CTRL
^G stands for “get basic help” - it’s also written right above in the middle of the bottom two rows

you try to close it with CTRL+X and it will ask you whether you want to save it and to which filename if you haven’t started it by giving it one.

or you write the file (to disk) with CTRL+O before you exit the editor with CTRL-X

@Mirdarthos

The output of the aforementioned command is:

options snd-intel-dspcfg dsp_driver=1
options snd-hda-intel model=dell-headset-multi
options snd-hda-intel power_save=1
9

Then it has been saved and if you rebooted successfully, it should be applied. To check, run the following:

sudo inxi --admin --verbosity=7 --filter --no-host --width

Provide the output here if you want us to check.

Edit:

Or maybe a better idea is checking the output of:

sudo sysctl -a

OK, I don’t see anything, so it doesn’t look as if they are applied to me. However, I’m the first to admit that I might be wrong.

So, if someone can confirm or dismiss my findings, that’s be great. Perhaps @bogdancovaciu himself even?

Edit:

WAIT, Please provide the output of:

I know it is from the Arch wiki, but is this actually correct?

The names of those two modules are:
snd_hda_intel
and
snd_intel_dspcfg

You would load the modules using those names.
Why supply the options to those modules using a different name which only looks similar?

with kernel parameters you meant these, from the bogdancovaciu link:

  • i915.i915_enable_rc6=1
    to enable deeper sleep states (power saving)
  • i915.i915_enable_fbc=1
    to enable framebuffer compression (power saving)

the modprobe swift conf is related to your previous issue with high cpu audio usage, that was fixed with switching kernels…

Mirdarthos & CO, you guys speak English here, but it beats me about the next step…

looks like @brahma had seen and remembered a previous issue of yours - and saw it solved

This whole thread therefore went down the wrong rabbit hole right from the start, it seems.

It’s not about the audio system’s modules energy savings options like here discussed.

Instead you should try to address the issue
by adding some options to your kernel command line
in /etc/default/grub

i915.i915_enable_rc6=1
and
i915.i915_enable_fbc=1
are related to your graphics card
not to the sound system

That would explain a lot. All in all it’s my fault.

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_TIMEOUT_STYLE=hidden
GRUB_DISTRIBUTOR=“Manjaro”
GRUB_CMDLINE_LINUX_DEFAULT=“quiet udev.log_priority=3”
GRUB_CMDLINE_LINUX=“”
i915.i915_enable_rc6=1
i915.i915_enable_fbc=1

Is this the proper layout, my dear persevering forumers?

18

no this is wrong … remove the
i915.i915_enable_rc6=1
i915.i915_enable_fbc=1
and put them inside this line to look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet udev.log_priority=3 i915.i915_enable_rc6=1 i915.i915_enable_fbc=1"

save the file, run this command:
sudo update-grub
reboot
