Lenovo Ideapad 5 2-in-1 14Q8X9 (83GH)

Start of discussion of this model with 360° hinge and touch screen / stylus, slightly different from the 83HL #36. This one is already supported by this boot image. There is ongoing work re brightness control, camera (why does it switch off after 30 secs), internal sound.

There is a new image available: Ubuntu_Desktop_24.10_Lenovo_Ideapad_5_2in1.img on Google Drive.

What is new:

• integrated GPU support on the image
• (supposedly) fixed camera behaviour, camera power supply should behave now
• switched to different display description (Samsung ATNA40AS01)

No sound support yet.

New image again: Ubuntu_Desktop_24.10_Lenovo_Ideapad_5_2in1_6.16rc.img.xz

What is new:

• integrated GPU support on the image, but not installed (breaks some snaps)
• definitely fixed camera behaviour, even working with different uvc models (tested on ThinkBook 16)
• switched to edp-panel which enables backlight control for this odd OLED panel. Odd in the sense that it adheres to standards.
• sound support. Which is of course dangerous, use with caution.

Working snap can enable the ubuntu-desktop-bootstrap package to install ubuntu from ubuntu. Currently testing this, seems to have evolved.

Updated the image after some review and feedback. Same name, to make sure the sha256:

I've noticed performance issues with this image. Could this be because GPU support is not installed? If so, do you know how to install it?

[jglathe]

The image has no active GPU support. There is a mesa repository on it, it can be made to work, I would prefer other ways, though. Like the one mentioned here, but also after first "install".
I will do another image, with working sound, got a bit sidetracked by the display panel (backlight adjustment doesn't work after suspend/resume, although suspend/resume itself works great) and life ™️

Hmm got around to install* from this image on my Ideapad 5 2in1. It was a pain, and I had / have to fix a few things to make it work more easily. Sound doesn't seem to work yet, need to analyze / debug. Main hurdle for installing (aside from no installer) was the missing entries in the QSEECOM compatible table. Without these, no efivars, and no good way to create a boot entry for grub.
Kernel package 6.16.0-jg-1 has these now.

Oh and the mystery of why the RTC doesn't work is also solved - needs efivars - so there's that
