Hi, after the installation of Legacy Firmware, I installed Ultramarine Linux and now have a dual booting THINKPAD C13 (MORPHIUS) with both OS working just fine.
Then I created a separate partition for my files (with GParted) as I always do, so that I have access to them from both Chrome OS and Linux.
And now I have to find a way to get Chrome OS to mount this partition.
I found some posts with directions like this one:
but I was hoping to get some help here, maybe someone did this already.
also I 'm pretty sure I tested the sound and was working fine, but now after a couple of restarts or something I did (???) there’s no sound on speakers. Headphones work though.
Do I need some script?
edit: I run the script for audio I found here but nothing changed unfortunately!
I can see that output device is named “dummy output”
any ideas?

I managed to sort out both of my problems, although it wasn’t exactly easy…
So l’ll put it here in case it helps someone.
First the audio problem. As I wrote I lost audio on speakers with UltraMarine Linux after first reboot. Now I believe the key remapping proccess is responsible. I tried everything with no luck, and decided to install latest fedora-xfce instead (for other reasons). I had exactly the same issue after remapping keys and first reboot - no audio on speakers. However fedora has extended audio settings and I discovered the output device was renamed…I had to switch to the new name and it worked fine since!
Audio was quite easy to solve, but getting Chrome OS to mount other internal partitions was an other thing…
Everything I found needed sudo with crosh, but unfortunately Google disabled sudo in crosh since version 117. And VT-2 terminal didn’t seem to work with these commands.
I though to ask ChatGPT, not expecting much of course. Actually first answer was the same I found and didn’t work, but I was amazed to see that it was coming back with updated aproach each time.
It guided me through the proccess, step by step, many commands and finally I had the partition mounted and managed to pin it to My Files. It even proposed scrips to automate the proccess after reboot, and repair in case an update screws something.
I was really impressed! Everything works just fine!
after remapping keys and reboot I had no audio on speakers. BT and stereo jack worked fine. It was the same with UltraMarine. I did nothing except key remapping and audio worked fine after installation, as it did with live USB.
I couldn’t figure it out with UltraMarine but with fedora I noticed the output profile was renamed from acp3xal…Pro to acp3xal…Pro 1. Second one works just fine. I’m pretty sure there was only acp3xal…Pro after installation.
In UltraMarine I tried the audio script, nothing changed. I went through all the settings but couldn’t change the “dummy output”. As with fedora, audio was working fine with live USB and initial installation.
