Re:Ubuntu OEM images available for download from Lenovo site

Hi @scheesecake 

 

Yes. The P14s AMD has completed Canonical cert: https://certification.ubuntu.com/hardware/202006-27980

 

It has similar energy cert issues as the T14 AMD - some higher power usage in sleep and power off that we're working on. It's been a fairly long and painful debug exercise but I believe the power off issue is solved by an EC update (it's under test not released yet), and then once we can pass e-cert I'm hoping to get those platforms online.

 

From a support point of view - they're on the Linux list so you should be good there.

Re:Ubuntu OEM images available for download from Lenovo site

2021-04-04, 6:51 AM

Hey Mark,

 

I've just received the Yoga Slim 7 Pro with the Ryzen 4900H. Turns out it's a bit of a unicorn. I've installed Pop OS and tried to update the Radeon graphics drivers woth official AMD ones and come to realise that it involves a hokey way involving updating the linux kernel and then installing the amdgpu drivers from back in June 2020! Now I'm having issues with the amdgpu not going into power-saving modes and draining the battery as well as showing a blank screen sometimes at the login screen .  My question is two-fold: when could I expect a ubuntu recovery image for  my laptop model; and is there an official way to update the radeon/amdgpu drivers that will solve the acpi/power draining issues that I currently face? Thanks!

Hi @AngrSpren 

 

Afraid the Yoga Slim isn't a Linux certified device which means it's not something that we've tested and confirmed working with Linux. It also means there isn't a certified Ubuntu image available for that model and I have limited levers to pull on to get support from the firmware teams.

 

Which kernel are you running? My understanding for the AMD Renoir CPU's is you'll need the latest kernel running to stand any chance of success?

Hi Mark,


You're right; I followed a forum post that recommended updating to Linux kernel 5.11.11 and installing amdgpu drivers from AMD.com. However, the issues with sleep and stability forced my hand. I've nuked the installation and installed Endeavour OS, which brings its own set of issues, such as unable to set any resolution other than native. Fun times.

Not sure if it will help - but the AMD cpus don't yet support modern standby (aka S0ix) sleep with Linux and I wonder if you're hitting that? You have to use legacy sleep (aka S3).

 

Some BIOS's will let you select the sleep mode as a configuration - check if your's has that option and if it does change that setting?

Hi Mark,

 

There's no 'S0ix sleep' option in the bios. The Yoga suspends quite well in Endeavour OS. However, to be honest, since the last response, I've had mixed results with Endeavour OS. While it is running on a more recent kernel than Pop OS, this was causing me issues with the resolution defaulting to 2k. As you can imagine, without appropriate scaling, everything on screen is way too small. The distro was also a bit unstable, freezing at random times.

 

So I nuked the installation and installed Garuda Linux w/ bspwm. I have to say it has been rocksolid for the past couple of days. The 'hybrid sleep' option works really well. The 'suspend' option does not seem to do anything. Although the distro is based on the same Arch linux base as Endeavour, it has installed the amdgpu driver and I have vulkan running superbly on the laptop. I am able to set the resolution at will, and I have not had a freeze, or unstable moment so far.I am honestly amazed at the stability of distro.

 

Maybe you could suggest some way to get the suspend feature working, as I am used to closing the lid to suspend the laptop. Let me know if you would like me to get any sys info outputs for you.

As a heads up - I just got off a call with AMD and support for S0ix has landed upstream just recently. I don't have a patchset but sounded promising.

 

I haven't had a chance to try it myself yet - but if you're up to building your own kernel might be worth giving a go and seeing if it now works.

Re:Ubuntu OEM images available for download from Lenovo site

Hi @MarkRHPearson 

 

I have been trying to get Ubuntu 20.04 to work on The X1 Titanium but I cannot get the laptop screen to work without nomodeset in the grub (which then does not allow me to change the screen resolution or get the external screen).

 

Any help in that regards would be very appreciated.

Hi @simonduskin 

 

I think I replied to your post in the forum - but we don't have an image for the Titanium yet as there were lots of issues around the panel not working on that platform. I'm looking into what the status is - please nudge me in a day or two if you don't hear anything.
