The processor runs at a frequency of 400 MHz, Linux kernel > 5.15

Support Kernel
1

The laptop is a Dell Latitude 5430, i5-1235u. I bought this laptop cheaply, replaced the SSD, and upgraded the RAM to 64GB. So far, everything works as expected. I’ve been using it for a year and a half and decided to replace the screen’s matrix, swapping the stock 250 cd/m² panel for a 400 cd/m² one.

I bought the new screen and replaced it, but after powering on, everything was very slow. The Btop shows the processor frequency at 400 MHz. I thought the issue might be with my Manjaro distribution, but after testing live USBs of Ubuntu, Fedora, and Manjaro with kernel version 6 and above, the issue persists with the new screen across all distributions.

However, if I boot any live USB distribution with kernel 5.15 or lower, the issue disappears. On my installed Manjaro system, I also downgraded to kernel 5.15 so I could continue working.

Out of curiosity, I put the old screen back in, and the problem disappears. The issue also doesn’t occur when using an external monitor without the laptop’s built-in screen. However, the old screen is quite dim, and it’s uncomfortable to work outside or near a window on bright days.

Changing power profiles doesn’t resolve the issue.

Welcome to the Manjaro Community!

Have you checked the refresh rate, etc.? Is the new display a higher resolution? There’s also the possibility its greater power draw could be causing throttling to save power, assuming it’s happening on battery.

There’s an option on my laptop for a display “upgrade”, which I’m interested in as my display is certainly not the best. So I’d be interested to see what happens with yours, if settings can be adjusted to get it to work.

Also, to me, that looks like a 1st generation i5 so pretty old now, 3 years older than mine. Maybe it isn’t that well supported now with the newer kernels?

A bit more system information may go a long way to help people who may be able to assist:

inxi --admin --verbosity=8 --filter --no-host --width

Cheers!

Could it be that the 2nd screen isn’t as compatible as you believed? Either that, or perhaps it’s faulty.

In any case, some housekeeping:

Welcome to the Manjaro community.

As a new forum user, please take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum to your benefit:

Required Reading:

Update Announcements:

The Update Announcements contain update related information and a Known Issues and Solutions section that should generally be checked before posting a request for support.

System Information:

Output of the following command (formatted according to forum requirements) may be useful for those wishing to help:

inxi --admin --verbosity=8 --filter --no-host --width

Be prepared to provide more information and outputs from other commands when asked.

Regards.

But the i5-1235u processor is not old, it was released 2 years ago, it’s part of the 12th generation Intel lineup from 2022.

It doesn’t matter whether I’m running on battery or from the outlet, on kernels newer than 5.15 (6 and above), the CPU frequency is limited to 400 MHz. On kernel 5.15 and below, the processor works as it should without issues. I’ve been using a laptop with a new display on kernel 5.15 for a month now, but older Linux kernels have issues with laptop hibernation, so I would like to return to version 6+.

I don’t think it’s incompatible, as I’ve been using this screen for over a month with kernel 5.15 and haven’t encountered any issues. The problems start when using kernels version 6 and above. Even Windows doesn’t have any issues with the processor during the installation process.

6

I just checked that and indeed, it’s a 12. I expected an extra digit on the number e.g. mine’s a 4300U and that’s 4th gen. :wink:

So, indeed an issue. I guess you have tried all of the current 6x series, including the latest linux613 (release candidate currently, as far as I’m aware)?

7

Well, first thing, some system information. This may help others find related information. Perhaps details of your replacement screen as well; one never knows what fresh eyes may discover.

I tried all stable versions of kernel 6, not the RC version. Latest 6.12

I added the result of the command to the top of the post. Thank you.

inxi --admin --verbosity=8 --filter --no-host --width

And about the screen model, I don’t know how I can check it.

I presumed you might still have the invoice and any accompanying documentation; either of these might have given some details.

inxi results are not helping much with that, either.

A quick Internet search has shown that the Dell Latitude 5430 is generally recommended as a solid base for Arch/Manjaro; but then again, you’ve made modifications outside the scope of those general reviews.

I noticed you’re running Wayland; it’s the obvious future of Linux; but have you tested under X11? Kernel 6.6 (LTS) and 6.12 should be sufficient to test.

Otherwise, nothing else comes to mind.

11

About X11 or Wayland doesn’t matter what I choose the result will be the same. About the matrix model, I bought this screen on eBay and all I have it’s a code LCD panel - P137G.

This laptop has several modifications including 400cd/m2 matrix screen

12

Well, according to the Internet, that seems like it should be the same as the original screen.

I found the following Service Manual (PDF) for the P137G listed on ManualsLib in case this is useful.

The best we can do for now is leave this open for other Members to comment; perhaps they may have a few thoughts.

13

I can recall a post about a machine stuck on lower frequencies but cannot locate it on the forum. This page might have some hints on what to try/test:

maybe change the governor to performance.
i have a few threads regarding this in my posts history.
and also since quit some time the measurement commands are apparently not accurate anymore?
watch -n1 cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq

i gave up on seeing as a result to this command all the cores show they’re at max cpu clock as it was before, i just set it to performance and leave it be.

15

Quoting from the OP for the benefit of those wishing to help:

The issue only exists with the new screen installed.

Command result. I think processor try to set more freq, but can’t. Change profile to performance doesn’t give any results

I can’t attach any images or screenshots. The result is 400000, and sometimes a little more for half a second.

17

your main problem is that the used frequency-governor is “intel-pstate”. this governor is designed for newer cpu’s and unfortunately overrides every other setting of frequency-control. you need to disable it by adding

intel_pstate=disable

to the existing parameters in

GRUB_CMDLINE_LINUX_DEFAULT="

run

sudo mkinitcpio -P && sudo update-grub

afterwards, reboot and report the given inxi-command. it should be acpi-cpu-governor

18

Is there a reason we think a 12th generation Alder Lake intel (circa ~2021) is ‘too old’ for intel_pstate?

Though I will mention

Does not seem like a valid option.
The options seem to be

  • disable
  • active
  • passive
  • force
  • no_hwp
  • hwp_only
  • support_acpi_ppc
  • per_cpu_perf_limits

https://www.kernel.org/doc/html/v6.12/admin-guide/pm/intel_pstate.html#kernel-command-line-options-for-intel-pstate

19

i did not wrote that the cpu is too old ! i wrote that this governor will deactivate any governor-setting by design ! @cscs read (!) before commenting !!!

This driver implements a scaling driver with an internal governor for Intel Core (Sandy Bridge and newer) processors. It is used automatically for these processors instead of the other drivers below. This driver takes priority over other drivers and is built-in as opposed to being a module. intel_pstate may run in “passive mode” via the intel_cpufreq driver for older CPUs. If you encounter a problem while using this driver, add intel_pstate=disable to your kernel line in order to revert to using the acpi_cpufreq driver
https://wiki.archlinux.org/title/Scaling_governor

20

I extrapolated from your suggestion to disable it along with the qualifying comment

that you meant that the cpu must be ‘too old’.

If that wasnt your intention then alright, but I dont think its an unfair reading of what was written.

Yup, I can read the wiki as well.
But my first suggestion would not be to disable intel pstate, as its generally desirable.

We should at least see how it functions when an acceptable value is used first, methinks.
