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

[Chris Guiver]

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on 'reboot' message (calamares on screen), plymouth has now been replaced by black screen & it's just sitting there...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

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

Another install & the same result..

The plymouth screen just pauses; and both my screens show blue background, lubuntu logo (no longer swirling) and "Powered by Lubuntu" bottom in the centre.

No black screen... it's just frozen.

On pressing ENTER the reboot occcurs.

This install is on the same box
- hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
install testcase this time was "Manual partitioning with separate /home" though I don't think testcase item (calamares install options) differ.

install is good once again.

Bug is MINOR issue though; unclean shutdown of *live* media only

Another QA-test install using the box; same daily & issue occurs again.

- hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
testcase: install alongside

install completes; i press enter to reboot (calamares) & system shutdowns down, last screen being lubuntu-plymouth..

screen just stops with blue background, lubuntu logo (no longer spinning, brightly-lit lower quarter but it's slightly-right this time, I thought slighty-left last time, "Powered by lubuntu" below that..

on hitting ENTER the system reboots as expected.
