[Bug 1942829] Re: on completion of install got enter to reboot message in calamares.. system started shutdown then blackscreen & sits

[Chris Guiver]

This reminds me of https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1925314 but 
- different box
- that only occurred on low-res displays (not 1920x1080 displays that are used here)
- it didn't blacken screen; xubuntu plymouth kept cicling without the 'press enter' message as it didn't fit on the low-res diplay

Reminds me of it anyway - is graphics in play here?  kubuntu & gnome no
longer like this box , but I've not had issues before with lubuntu

Title:
  on completion of install got enter to reboot message in calamares..
  system started shutdown then blackscreen & sits

Status in casper package in Ubuntu:
  Incomplete

Bug description:
  Lubuntu impish daily QA-test install to
  - hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
  (testcase: full disk, no encryption, BIOS, no internet, swap)

  on 'reboot' message (calamares on screen), plymouth has now been
  replaced by black screen & it's just sitting there...

  been left awhile... switching to text terminal & back and now I can
  see "Please remove the installation media, then reboot." message when
  I return to GUI (ctrl+alt+F1) but it was just black screen before
  then...

  on enter I got nothing either... i eventually SysRq-REISUB to get it to reboot..
  I've experienced this before, but I don't think on this box & not recently...

  I don't think I can ignore this, but it's currently of no value
  (incomplete?) and will need exploration..

  ** Expected outcome

  I expect a eject media message to appear, and it to reboot on pressing
  enter

  ** Actual outcome

  Just black screen... I got the message only by typing Ctrl+Alt+F4
  followed by Ctrl+Alt+F1, then the ENTER key did nothing.. eventually
  achieved reboot via SysRq+REISUB

  ** New but random issue??

  Note:   I've installed to this box once on each of the prior two
  dailies without this issue, same full-disk except encryption was used
  (with & without-internet; no-swap I think on prior two days but I
  don't see encryption/swap as impacting this issue).  This box is used
  for installs; so I'll repeat this (or at least equivalent) installs
  and we'll see if it occurs again...
