Xubuntu hirsute live system, on shutdown no "Please remove the installation medium, then press ENTER:" message appeared

[Chris Guiver]

Xubuntu hirsute daily installation QA-test on
- dell [optiplex] 755 (c2d-e8300, 8gb, amd/ati radeon rv610/radeon hd2400 pro/xt)

At completion of install, it suggested I reboot so I was accepted. I then got the Xubuntu plymouth screen, and it sat there ... for >60 mins

** Expected Result

Xubuntu plymouth close/shutdown screen
Message "Please remove the installation medium, then press ENTER:"
I press enter and it reboots

** Actual Result

Xubuntu plymouth close/shutdown screen
It just sits there... no message (>60 mins for this test)

On enter it reboots

** Extra notes

See http://iso.qa.ubuntu.com/qatracker/milestones/419/builds/223307/testcases/1300/results for my comments at test

I don't believe this is new, I believe I saw it during the groovy cycle too; however just pressed enter

I also believe it's related to this box screens. This box has 2x 1280x1024 displays, however on boot of Ubuntu & Debian *live* systems the monitors show as mirror'd, and one display is currently running at 1024x768; being mirrored I think both run at the lower resolution thus I believe the 1024x768 screen is the reason this issue occurs.

The Xubuntu logo was not central on the display; I think it was out b/c of displays both running at 1024x768, and the portion out is I suspect appropriate if drawn for 1280x1024.

I can re-create this (this box only though, which I believe relates to video card and/or screen resolution)

I booted a recent (20201122) Lubuntu hirsute daily, and it shows the message on that box.

another xubuntu hirsute QA-test on same box
- dell [optiplex] 755 (c2d-e8300, 8gb, amd/ati radeon rv610/radeon hd2400 pro/xt)

no message, it was left >35 mins with xubuntu on each display & circling-loopy thing, but no message appeared.

the xubuntu logo isn't centered on the displays (it is on one, but not the other), as they are being used at different resolutions (1280x1024 & 1024x???;) and I think the "Please remove the.." message is being drawn off-screen..

Next boot & install on different box (2x 1920x1080) & message appears at bottom of screen; both message centered on display

Status changed to 'Confirmed' because the bug affects multiple users.

[Sai Vinoba (saivinob)]

I confirm no message shows for removing the iso medium. Tested on Xubuntu daily build 20210224 ISO. If we hit escape we see following error.
"Starting shuts down the 'live' preinstalled system cleanly...entd or progress polling."

[Sai Vinoba (saivinob)]

On today's test (20210226 ISO), I noticed the message is shown for live-session but not for install test case (reboot after install).

Hitting enter proceeds to reboot the system but if we hit escape, we see error as stated in comment #5.

[Sai Vinoba (saivinob)]

For 20210227 and 20210228 ISOs noticed the remove medium message is showing correctly.

Later accidentally (embarrassingly) noticed that previously when I reported message not shown, it was not in fullscreen mode and the message was blocked from view. If we scroll down the message is at the botton.

In Ubuntu MATE (probably in Ubuntu also) the remove media message is about an inch or two below logo and easily covered in the view. In Xubuntu however, the message is all the way down (footer) of the screen and can be missed if (like in my case) the vm screen is not set to fullscreen.

[Dimitri John Ledkov (xnox)]

Does pressing any key on keyboard make the message render better?

What are the exact words of the message seen? There are two wordings one for graphical splash and another for serial text. One is "and press enter" the other one is "and reboot" or some such.

Does changing TTYs make the message appear? cycle with ALT-[arrow key right] repeatedly.

[Chris Guiver (guiverc)]

Sorry Dimitri/xnox. I didn't notice your reply before now, I was searching for this due to re-occurrence.

No words appear on screen, except Xubuntu logo (I see as graphics/image) and a twirling thing below that that just keeps twirling...

It'll sit like that for 2.5 hours (longest I've left it)

I just did a QA-test install of today's daily again on
- dell [optiplex] 755 (c2d-e8300, 8gb, amd/ati radeon rv610/radeon hd2400 pro/xt)
and this issue occurs again...

It occurs only on boxes with lower-resolution 4:3 displays.

This box has two dell displays (technically 2x 1280x1024) but for some reason one I believe is using only 1024x768 currently, and the daily (live media) always boots with this box in MIRROR mode so both screens always show the same thing (the mirror mode isn't unique to Ubuntu; Debian (non-free live) boots in mirror mode too).

I don't know why the second display is 1024x768; except it dropped to that when I switched the display from landscape to portrait and I live with it

@Chris could you please answer Dimitri's questions?

"Does pressing any key on keyboard make the message render better?"

"Does changing TTYs make the message appear? cycle with ALT-[arrow key right] repeatedly."

[Chris Guiver (guiverc)]

Sorry I didn't notice the request for info...
Hirsute has released so it doesn't matter there...

I can resurrect this if I confirm it's the case with impish.
I zsync'd today's Xubuntu ISO (impish) and confirm the issue remains :(
- dell [optiplex] 755 (c2d-e8300, 8gb, amd/ati radeon rv610/radeon hd2400 pro/xt)

It just sits there with Xubuntu & a spinning logo without text.

I pressed SPACE bar, then started the Alt-F4/arrow to switch to terminal and the box just turned off.. so some key was taken like it was an enter.

At no point did the screen change (before turning off; nothing became visible; position did not alter - both screens showing the same).. I was watching the display far more closely than keyboard so I can't be sure what keys I hit, but it was NOT enter with hands on left end of keyboard)

I booted Xubuntu impish again... this time using only Alt+Arrow

From Xubuntu & twirly thing
Alt+Left = cursor top left blinking
Alt+Right to return to Xubuntu & twirly

Alt+Right = message top "Please remove the installation medium, then reboot"

I was unable to work out what keys caused it to shutdown last time... It shutdown this time only with enter.

[Daniel van Vugt (vanvugt)]

I think there were *multiple* causes of this kind of bug..

Up to plymouth 0.9.5git20210323-0ubuntu1 it lacked robust shutdown support. That was fixed in 0.9.5git20210406-0ubuntu1 but the new version also introduced bug 1942987.

I think we should track this in bug 1942987 and only worry if it still doesn't work after that is fixed.
