[Bug 2083285] Re: Ever Diminishing support for lenovo Helix 2

[udippel]

Let me at least place a closing remark here. After some weeks of an unusable system, I have done nothing more than completely wipe the fresh install of 24.04.1, and done an install of 22.04.5. 
And, to somebodies surprise, everything once again works. From the set automounts (for which you sent me to askubuntu), and all else. 
Except of the bugs that I already had filed for 22.04, that is invisible grub boot menu and display trouble over the dock. 

I am sure, if anybody else happens to have this type of lenovo Thinkpad,
he might well want to know that neither upgrade nor fresh install will
deliver any useful system.

If you guys were fair, you'd add this as a remark into the Release
Notes.

To my own surprise, even the kernel 6.8 (automatically installed for
22.04.5 this time), doesn't seem to be THE culprit, despite of its
crashes with 24.04.1

Title:
  Ever Diminishing support for lenovo Helix 2

Status in grub2 package in Ubuntu:
  Invalid

Bug description:
  When I bought my first Helix 2 (lenovo), all functionalities were supported, including video via the docking station "Think Pad USB 3.0 Pro Dock" (40A7) under kubuntu 18.04.
  Since then, per each next LTS, support has become less and less. It started with changes in mesa, combined with evdi, that made any video display over the said dock impossible. With the update to 22.04, grub failed to be supported by not allowing any more choice of installed operating systems. With 24.04 finally, start, stop, reboot, shutdown are not working properly any longer. Once a day the system shut down on their own, sudo reboot results in poweroff, from which a normal on/off doesn't lead to a reboot, respectively the systems (I have a multitude) do not shut off any longer, but show the (boot/uefi) logo "lenovo" for eternity. 
  The systems are almost unusable with 24.04.1. They show almost identical symptoms, one updated from 22.04, one fresh install. All systems are fully functional hardware-wise, however, because they all have W10 installed in parallel. And by booting to W10 ("Enter"->F12->Windows boot manager) all functions work properly, including video over the 40A7-dock and power off/reboot. 

  Over the course of time, I have reported all vanishing functional support with bug reports. So far, the situation has only gotten worse. From a fully supported system under 18.04 through the first decline in 20.04, 22.04 and now 24.04, we have unfortunately reached a state that reminds me of the early stages of Linux in the last decade of the last century. 
  I don't know what more I could do than writing bug reports? I also can't exclude errors on my side; though I have always followed diligently the respective update respective fresh installation guides. I have been almost exclusively on >Linux since RedHat 5.1, and I am most disappointed that things have been spiralling down such far and fast, instead of further improving.
