Error

After disabling intel_pstate system doesn't boot, Seems just stuck at showing vendor logo.
After reverting the changes of /etc/default/grub it boots normally again:
This is my grub file:

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable resume=UUID=75014eab-9c4f-4920-a93c-a146720c5adc"
GRUB_CMDLINE_LINUX=""

GRUB_DISABLE_OS_PROBER=false

Tried removing resume=UUID=75014eab-9c4f-4920-a93c-a146720c5adc, But it's the same.
After removing intel_pstate=disable and executing update-grub through the recovery-mode system booted system normally.

This isn't really an auto-cpufreq issue. But make sure you have the following packages installed using:

sudo apt-get update

sudo apt-get install acpi-support acpid acpi

[niamotullah]

sudo apt-get install acpi-support acpid acpi

E: Unable to locate package acpi-support
But installed acpid and acpi.
Still the same

The package named acpi-support is not available in Ubuntu 23.10 or any recent versions of Ubuntu. The functionalities previously offered by acpi-support are now integrated into the kernel itself. This means you don't need to install any separate package for ACPI (Advanced Configuration and Power Management) support.

Definitely not normal behavior. Maybe because it's a Huawei laptop. Personally, I didn't even know they made laptops.

I would check your bios for any relevant settings. It might just be the firmware

Let me know if i can be helpful somehow with my device

[shadeyg56]

You can try running sudo dmesg to look for any relevant messages that might point to something.

In your bios, look for settings related to dynamic CPU frequency or P-states

I don't actually know what signs to look for, I'm a newbie on Linux.
Can you suggest something? maybe something to learn.

These are all options in my bios:

There is some extra information that might help:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable resume=UUID=75014eab-9c4f-4920-a93c-a146720c5adc"

I have disabled intel_pstate by replacing intel_pstate=disable with intel_pstate=passive .

But now system are so slow on battery. UI lags so much, almost unusable.
Any solution?

I have disabled intel_pstate by replacing intel_pstate=disable with intel_pstate=passive

That means you have enabled intel_pstate

But now system are so slow on battery

This is likely because of how intel_pstate handles the powersave governor
You can change to using a different governor on battery by using a config file. Instructions can be found here in the README
