Title: Lite 3.8 Blank Screen After Opening Lid
Post by: MattC on October 11, 2021, 02:35:53 PM
Hi, Newbe, here.

Not strictly a startup question although it does have a connection.  I have posted this question on another site, but, although I received very good replies, I didn't get a working solution.  As this is a Lite specific forum, I'm hoping someone here will be able to further advise me.

I have Lite 3.8 installed on my old Samsung NP-N110 laptop and it seems to work fine.  When I close the lid and reopen after a time, it asks for a password.  This is fine - although I can't figure out how to stop this - but when I enter the password, the screen goes blank and remains blank.  I am unable to do anything with it except for hitting the power button to shut it off.  It seems to close down OK, as when I hit the power button it chugs for a while then shuts down.  Also, the numlock keeps turning on.

So if anyone has an answer to any of the following I'd be grateful:

1. How do I stop the p/w request from appearing when I've closed the lid for a time? (This is on mains as well as battery.)

2. What's happening and how do I prevent the blank screen after I've entered the p/w?

3. How do I get the numlock to stay off on boot up or at a p/w input?

Thank you.

FYI: the p/w request at startup is on, but the same problem with the p/w after opening lid happens even when this is off; the BIOS is set to numlock on.

Thank you.  I appreciate it's unsupported by updates.  Are you suggesting that it is unsupported at all, even in a forum?

Unfortunately, yes, since Ubuntu 16.04 which is the base for Linux Lite 3.8 reached EOL(end of life)last April https://ubuntu.com/about/release-cycle this also means end of support from Ubuntu as well as from Linux Lite, and as you probably understand, newer versions takes precedent. That being said, for your issue, you could try and look in power settings, there should be an option to configure what happens when you close the lid. As for the password, in session and start up uncheck where it reads Lock screen before sleep and in power settings uncheck where it reads Lock screen when going for suspend/hibernate or some similar wording.

Thank you.  Unfortunately this doesn't help.

Do you know of a forum that caters for Lite 3 users?

You're welcome. Too bad that didn't work. Not exactly, but you could try here https://www.linux.org/ and here https://www.linuxquestions.org/questions/ and there are many other Linux forums you could try, just search for "Linux forums". :)

stevef, it's set to 'Switch off display' on both batt and plugged.  However, the others - 'Suspend', 'Hibernate' and 'Lock screen' - are equally as unappealing.  I would have thought, though, that it should only ask for p/w if it was set to 'lock screen' (or the others), but not just 'Switch off display'.  I have no other laptop that I can test this on to see if there's a problem with mine.

Moltke, thanks.  I'm a member of the Linux Community forum (where this question was originally posted), but I'll have a look at the others.  One thing I'm reluctant to do is join many different groups, but I'll consider your suggestions, thanks.

FYI --- LL3.8 was different than the later versions of LL... Yes it was a great OS at the time..
@matt as this version is no longer supported you may be finding yourself attempting items with no results.


I would highly suggest using the forum search, you can find answers when the OS was supported...

Matt,

I have an Acer one 722 notebook which is about 10 years old.  The Acer still has LL3.8

When set to 'switch off display' on lid close it appears to do just that and when opened again the display reappears as expected - i.e. not locked.

When set to 'lock screen' on lid close - when opening I briefly get a text type screen that is blank except for an underscore cursor top left, which changes to a black screen with brief glimpse of the mouse cursor centrally.  The screen remains black unless/until I move the mouse which gives the GUI unlock screen.  Entering the password here which gets me back to normal.

Essentially the Acer appears to work as expected with regard to lid closing and opening so doesn't reproduce your issue and confirms your thinking on what *should* happen.

If you lock the screen manually from the menu does it subsequently unlock ok ?  The answer to that might suggest where to look next.

I'm not quite clear with your num lock issue and when it toggles.  The Acer num lock status is unaffected when going through a lid close open test, but from your description, I don't think you were linking the two issues.

Under settings->keyboard->behavior there is a 'restore numlock state on startup' checkbox which is ticked on my system.  This may be interacting with your BIOS num lock setting.

Please do not support, an unsupported OS. I appreciate the willingness of the people here, but we simply can't do this. The reasons are very obvious.
