I've tried to install LMDE 3 but wifi was not recognized. As this was just a test of this distro, i fell back to Linux Mint 19 / Cinnamon.
System is installed on the SSD and /home on the HDD.

Unfortunately there is a problem with the PCI express bus.
Kernel log is spammed with this error:

Code: 
Sep  2 00:07:21 lafite kernel: [  309.797319] pcieport 0000:00:1d.0: AER: Uncorrected (Non-Fatal) error received: id=00e8

According to lshw command, Device 0000:00:1d.0 seems to be the Intel SSD 760p.
I am not sure how to resolve this. I've disabled aspm by setting
Code: 
pcie_aspm=off
in Linux boot command line of grub, and the errors are gone.

But I am not sure if disabling this power management feature is the best way, or if there is a way to really correct the problem (bios update maybe ?)

Thanks for your help if someone has a clue.

Hi Graham,

Sadly I have seen your message too late and bought an Ultrabook with the same SSD! I have the same log spam.

I'm going to try with a distro that has a more recent kernel, but did you ever manage to track down what was causing this and a fix? Did it impact performance etc? Were you able to find a BIOS update? I've seen that fixing this issue in other forums posts for different laptops.

Thanks!

Dammit, I ordered the same configuration.

Colhul, can you please report the status of this issue on your computer? How large are the kernel logs created by these messages? What is the effect on end-user experience? Did a recent kernel help?

A very similar error has been reported here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1758545. It seems to be hardware-related rather than kernel-related, and also doesn't seem specifically related to the Intel NVMe SSD. A BIOS update solved the issue for the bug reporter. If that is indeed the case, then we're in trouble, because Clevo does not provide BIOS updates for this model, only drivers: see https://www.clevo.com.tw, Services > Downloads, model is N141ZU. If Clevo did provide BIOS updates, it would only be as Windows binaries, too.

I'm thinking of buying this laptop. Any updates on linux compatibility? Maybe better to have a SATA3 SSD than M.2? Or is the fix that Graham proposed ok?
Two other questions:
1. Can keyboard backlit be off?
2. Is screen matte?

The Samsung m2 drives are OK with Ubuntu in the 14" Lafitte and I have run Ubuntu on a variety of machines with Samsung m2 drives.

I'm updating this thread for reference. First of all, regarding the PCI Express bus error reported by Graham.1 and Colhul: I have followed the following advice: https://unix.stackexchange.com/a/369090 to give the kernel the option pci=nommconf in order to have the configuration space of the PCI device (apparently the Intel SSD 760p Series) accessed by a different method than memory-mapping. This strategy works around the issue, in my case at least. More information in the relevant bug on Launchpad: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1758545/comments/11.

do you know if there are some issues on Linux with Lafite and ADATA SSDs?

No idea.

1. Can keyboard backlit be off?
2. Is screen matte?

Yes and yes. As far as I can tell, everything on this computer (and hopefully its current iteration, lafité iv), works out-of-the-box with Ubuntu 20.04 (development version) as of the time of this writing, with the exception of the following things:

1. The PCI Bus error discussed in this thread: work around with kernel option pci=nommconf

2. The Additional Drivers tool reports that the device "Intel Corporation: Wireless-AC 9260" is not working, and suggests using a manually installed driver (cf. screenshot): yet this device is actually supported by the iwlwifi driver (cf. Intel and kernel documentations); the appropriate firmware file is present in /lib/firmware; lsmod | grep iwlwifi, lspci -v, lshw, dmesg | grep iwlwifi show that the driver is in use and working, and I am indeed writing this post connected to an ac (5 GHz) wifi network, where I can verify a ~130-160 Mbps download speed, so the device seems to be working all right.

3. The fan, when it is active, sounds noisy to me (the low-quality kind of noisy).
