[Kernel-packages] [Bug 1870971] Re: [amdgpu] (X)ubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API when in battery mode

2020-06-29 Thread Franz Heinz
@Katan Maier (katastic): Did you encounter any problems with the GRUB
configuration mentioned in post #20?

And does this fix the problems with VLC, too?

Title:
  [amdgpu] (X)ubuntu 20.04 boots to black screen on Lenovo Ideapad
  L340-17API when in battery mode

Status in linux package in Ubuntu:
  Confirmed
Status in vlc package in Ubuntu:
  Invalid

Bug description:
  Freshly installed Xubuntu 20.04 shows black screen instead of login
  screen upon boot on Lenovo Ideapad L340-17API. It is not possible to
  chvt to text terminal when boot is stuck on black screen.

  Booting with 'nomodeset' kernel option works properly but is not an
  option (e.g. screen brightness is not adjustable in this case).

  Another workaround is to ssh to laptop and run systemctl restart
  display-manager.service. After 5-10 seconds upon executing this
  command perfectly working login screen appears.

  Check dmesg. There is apparently related messages from amdgpu driver:

[Kernel-packages] [Bug 1870971] Re: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API

2020-06-18 Thread Franz Heinz
Can confirm that the problem occurs on my "Lenovo IdeaPad L340-17API"
regularly when power isn't plugged in.

On some occasions I got a corrupted root filesystem as a consequence of having 
to turn the system off "hard".
Furthermore I noticed that sometimes the Power-LED began to blink instead of 
glowing steadily.
