I have not looked yet into what that actually means (e.g. CPU/GPU not entering certain power saving states), but at least suspend and wake-up seem to be working now as expected.
Thanks for the detailed analysis.
1. Have you tried hibernate (instead of suspend/sleep)?
2. How is the battery life?

Hibernate seems to work well without problems (I followed those instructions).

The battery life is pretty bad at the moment: just sitting there with an idle desktop the battery dropped by 15%/hour.
Even during "sleep" (as indicated by the blinking power LED) the laptop stays quite warm and still drains about 10%/hour.
Also, when monitoring the CPU states using i7z, the CPU never enters states lower than C1.
There are a few ACPI errors at boot that I have not looked into yet:

Wow this is horrible.
I really was intending to buy this as it is one of the nice matte screen laptops with 1.2 kg (replaceable SSD and RAM). Seems I need to go for thinkpad P14s (about 1.5 kg).

Mind you that this is probably because any type of power management being disabled inside the BIOS.
It might be quite a usable solution just to disable suspend on the software side to work around the wake-up issues (and use hibernate instead, which is quite fast because of the SSD) and re-enable power management in order to improve battery life.
It is quite possible that there are going to be a few more fixes for "Tiger Lake"-based machines (or also that using a newer working kernel already improves things). If I have time during the holidays, I might try a few more things.
Now that hibernate is working (@lquser2021 thanks for the idea ) I have reset the PM options in the BIOS which greatly reduces the power drawn.
After an hour of idling, the battery only dropped by around 5%.
Being aware that this is not an extremely precise estimate, I would assume that the improvement is by a factor 2-3.
It is likely that this could be fine tuned even more using powertop.
As for the decision of what laptop to get, those are my main impressions of the U7411:
On the plus side,
the display is quite ok (although 1080p 'only').
In contrast to what a previous poster said, it has working keyboard backlight (Fn + Space switches the brightness between off/half/full)
Fan noise is quite bearable (not constantly running as with other laptops I had and IF it is running then not too loudly)
Graphics performance is quite good and stable (given that it is 'only' Intel integrated gfx)
reasonable amount and selection of connectors (especially in comparison to laptops with only 2x USB-C/Thunderbolt)
What I don't like:
when opening the display more than 90 degrees the base of the laptop lifts upwards. While it might be a nice idea for putting the keyboard at a slight angle and optimizing air flow, it just seems wrong from a mechanical point of view. It might also leave scratches on a sensitive surface as the display lid is not rubber coated.
feel of the keyboard is average
small trackpad
lack of a trackpoint
Personally, I have always waited for the perfect new Thinkpad that could compete with the design and quality of e.g. an T42p. To the best of my knowledge, this day has not come yet.
For different reasons, I have been using Macbooks over the years and recently got a Macbook Air M1 (2020).
From a build quality point of view, you could probably not get much better.
It also does not even have a fan, performance is great, display is gorgeous and Apple trackpads are (comfortably) huge.
Using Homebrew as a package manager, I can install almost any tools that I ever used on a Linux machine.
On the other hand, I never have to worry about hardware support issues.
Last but not least (and sort of ironically), it is cheaper than e.g. the U7411.
The non-Apple options I have looked at before were the Dell XPS 13 and different Lenovos (X1, T14s) but always found a deal breaker.
Oh, and there are obviously brands like System76 and Tuxedo...the former seem nice but overpriced (and harder to get in the EU) while the latter seem to lack in quality, at least to me.
The Framework Laptop could be a nice and sustainable device (and also seems to come with a certain support for Linux by the vendor). I have never seen one in person though.

Reason: Corrected typo
Thanks again for the detailed summary. Yes, I have been also tempted to get M1 (as I find it sometimes around €800 in amazon warehouse deals) and as a previous macbook air user (from work) - was great to go to conferences etc. But one deal breaker is the glossy screen that gave me headaches full days work.
Anyway glad that U7411 is in a usable state. Once the holidays are over will go the 'secretariat' and order one.
frohe weihnachten und einen guten rutsch ins neue Jahr 2022.
(...) one deal breaker is the glossy screen that gave me headaches full days work.
I used to be religious about matte screens but sort of got used to the glossy MacBooks myself...it might help that I mostly use it after work during the night...
On a more serious note, there are anti-glare "screen protectors"...but I have never tried them.
As for the U7411, we are waiting for docking stations to be delivered in January that will be interesting to try as well. If I get around to trying another distro and reach new conclusions, I will add them to this thread.
Thanks for the wishes, the same to (all of) you too!
about matte screens but sort of got used to the glossy MacBooks
True. At the old job, we had no choice - just got a macbook air. Now due to home office, we have a choice - and choice is sometimes a pain. I just cannot find a lightweight and linux compatible device - in a reasonable price.
BTW, may be the Intel Iris Xe Graphics needs different kernel. If I google the lspci from your device
(Out of craziness - yesterday got myself Jasperlake Pentium(R) Silver N6000 (Acer Swift 1 (SF114-34-P6U1) - 14" Full-HD IPS, Pentium N6000, 4GB RAM, 128GB) from notebooksbilliger for €250. Just works out of box. Wonder time to move everything to cloud!
I am not seeing similar issues as the poster in the thread above (which is from about a year ago, and he was still running kernel 5.4.0-56-generic).
It is likely that all recent kernels work reasonably well, at least wrt the graphics and after installing the non-free firmware.
In any case, I have run a game from Steam that uses the Unreal Engine, and it worked fast and without artifacts.
However, switching to Ubuntu/Linux Mint kernels newer than 5.11.0-43-generic will break at least the touchpad driver.
I have booted a few different distros today that showed the same issue. Will keep looking into that...

That sounds lovely.
It would be interesting to know how well it deals with video call software such as Jitsi Meet, MS Teams, Zoom, Signal, etc...

This problem is fixed by loading i2c-hid-acpi instead of i2c-hid, will keep looking into suspend behaviour with newer kernels now.

So far seems good. I tried so far bigbluebutton and zoom (app). Seems OK incl. screensharing. Mind you it has not the best webcam. Even compilation speed of apps with Android Studio is comparable to my 6 gen intel Dell laptop with 8GB RAM.
Amazingly this fanless device works well with 4K TV via HDMI.
This is an issue I have been trying to fix for a while now, I am running Kubuntu 20.04 and whenever I put my laptop to sleep or close the lid and try to wake it up again the LED's at the back of the screen turns on (as well as the fans), but there is no login screen. I have to then manually shut down my laptop then restart it, go through the GRUB menu, select Kubuntu and then go to the login screen
My laptop = Hp Laptop 15-db0xxx (Ryzen 5 2500u with Radeon Vega 8 Moblie Graphics)
Had the same problem, running Kubuntu 20.04 with 2 users configuration, on the 2nd user after running a game I will have a black or frozen screen after wakeup. In the old days, Kubuntu had by default configured a hotkey sequence to kill the X server Ctrl+Alt+backspace. I activated the hotkey sequence in system settings and it works for me. Basically, I have followed this on the best SPAM partner in SPAMtown and it's working smoothly after implementing this. Go to System Settings, Hardware, Input Devices, Keyboard, advance, find "key sequence to kill the X server" and select Ctrl+Alt+backspace. Hope this work for you too.
I FINALLY FOUND THE SOLUTION !!!
So I changed from Kubuntu 20.04 to Ubuntu 20.04 LTS and I still had the same problem of the screen's LED's turning on but the screen remaining black and not showing the login screen after I had turned my laptop on from sleep mode.
SOLUTION:
I had to change the boot order of the OS in my BIOS, originally Windows was put first then it was Ubuntu/Kubuntu so I had to change it so Ubuntu/Kubuntu would be first and Windows was second!
I tested this on Ubuntu, but I am pretty sure that this should work on Kubuntu if your boot order has Windows first!
I hope this will help anybody else who has had this issue or one that is similar!

Fujitsu U7311 wake up from sleep to RAM finaly working!
Good day, i have Fujitsu U7311 with BIOS 2.34. My OS is Debian (bookworm/sid) upgraded from stable release. Yesterday my wake from sleep started to work after upgrading to Gnome 43 on Wayland. Wake up is NOT working on my machine with X11 window system, but it DOES WORK with Wayland window system. My kernel is
@LK7R did you also upgrade the kernel before you got lucky or just Gnome? I'm currently running Ubuntu 22.04 and it still uses Kernel 5.15 (even if I install the HWE kernel). I would be fine with updating the kernel to a newer version by installing a mainline kernel, if necessary, but I don't want to move away from a non-LTS distro for this machine, so the Gnome 43 update is something I don't want to do.
If you only upgraded to Gnome 43, chances are that me upgrading the kernel won't help and then I won't bother...

Hi,
problem seems to be in the BIOS handling of the low power modes. I suspect that there is either some bug or fix in power management of Gnome 43 with Wayland. Even though the combination of low power settings in BIOS and Gnome 43+ on Wayland works, you can really tell it struggles (waking up is kinda slow etc.). Since initial post i was able to track down BIOS power management settings that enables resume from sleep to work with X or Wayland regardless on desktop environment. Only down side is higher battery drain while in sleep to RAM which I solved with:
On my Fujitsu U7311 laptop there are BIOS options:
Code:
"Advanced > Miscellaneous Configurations > Hardware Power Management"
where "CPU Power Saving(Battery)" needs to be on either:
"Normal" or "Low Power".
The same applies for "CPU Power Saving(AC)". Option that breaks resume is the "Long Battery Life" one, which I suspect is some deep sleep C2 state from which eDP won't wake up correctly.
My laptop has:
Code:
Intel® Xe Graphics (TGL GT2) working via kernel modesetting on i915 module.
Then resume from sleep works just fine on these kernels (tested on my U7311):
Code:
5.19.0-2-amd64
6.0.0-6-amd64
6.2+ (tested)
My guess is that it will work on 5.10+ just fine as it seems to be BIOS power management related bug.
