[Bug 2084191] Re: [X1E] Request: Add support for Lenovo Yoga Slim 7x

[Matthew Schiller]

I installed Ubuntu 26.04 Snapshot 3.  The other images including the X1e
specific images, wouldn't finish the install and failed in various ways
trying to install for me.

In Ubuntu 26.04 everything seems to work except the camera from a
hardware perspective.

However:
1) It seems that the laptop doesn't stay on AC charge properly.  What seems to be happening is if the battery becomes fully charged, the charger stop and the laptop transitions to battery.. Unfortunately the charger doesn't seem to start over.  Effect?  Leave your computer plugged in overnight, and find it at 25% the next morning.  Not ideal.....  unplug the charger and plug it back in... Charge starts and everything is normal... at least until the charger starts again.   This is probably the biggest show stopper for me.  I can live without a camera... But flaky charging will drive me back to windows prolly....

2) Sleep definitely doesn't work.....
