Unable to Unlock - No login prompt (intermittent)

Support GNOME
1

A while ago I logged an issue where, intermittently, I wouldn’t be able to sign in after restarting as I wouldn’t be presented with a login prompt.

This is here: Grey screen - No login prompt

I also have an issue where I get the same but when I’m already logged in - I’ve been away for a while and left the PC on, I come back and I have a mouse that’s working fine but no login prompt at all. In order to get back I have to hard reset the machine.

Here’s my inxi --admin --verbosity=7 --filter --no-host --width

Is anyone else having similar issues (they are very intermittent)? I’m wondering whether this is just a bug in the current GNOME version and not just me and if so how I would go about reporting that - whether I do it for Manjaro or upstream with Gnome?

I found this: Where do I report bugs

I’m running Manjaro on both my primary machines now so I’m watching my laptop for similar behaviour - currently it’s not bearing that theory out but they are quite different beasts.

I don’t want to waste anyone’s time creating a bug report for a random intermittent bug that may only be my machine being awkward - intermittent bugs are the worst.

To follow on from this I can confirm that this issue: Grey screen - No login prompt is NOT solved - I have just had to go through a cycle of 5 reboots (some soft, some hard) to get a login screen to come up so I can sign in after a load of updates installed.

Eventually I had to unplug the machine while Manjaro was started (with no login prompt) for 20 seconds and plug it back in again as the Power button seemed to just keep putting the macing into suspend mode and I couldn’t get it to switch off any other way (My Power settings are set for the Power Button to switch off).

This got me thinking that these issues could be linked to Hibernation / Power type stuff.

I normally just switch all that off on Windows as…
a. It eats up my hard drive space because I’ve got a lot of RAM
b. It doesn’t work half the time

Is there a way to disable power saving features in Manjaro like in Windows (suspend etc.)? That may be a possible cause for me.

I found this: Power Management - Manjaro

I’m not clear though if this is adding a power management layer when I want to turn it off if there’s anything running by default really so I may be barking up the wrong tree.

My settings in GNOME SETTINGS > POWER are…

  • Blank Screen: 10 minutes
  • Automatic Suspend: Off
  • Wi-Fi (on)
  • Power Button Behaviour: Power Off

I would take this as suspend / hibernate etc. as being disabled - but is there something I’m missing or something that takes over outside of the user account level which could cause similar behaviour?

There’s some useful info on power things in this question: After wake up from suspend or hibernate i can see the desktop from before - I shall review these files too for anything that seems unexpected.

Disable the iGPU from BIOS and enable early KMS for the nvidia GPU by adding in the /etc/mkinitcpio.conf at the MODULES line:

MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

then run:
sudo mkinitcpio -P
sudo update-grub

Not sure, but maybe also remove plymouth from HOOKS, the package and also switch from gdm-plymouth to gdm

4

My iGPU is already disabled - I’ll check out the KMS settings next week when I have access to the desktop again. Reading about this, this option looks promising - thanks.

5

I’ve done the first part and set the MODULES value, created the new image and updated grub.

I’ll see how that goes.

Will this survive a significant update? I think I’ve got a load of package updates due to install imminently.

6

The /etc/mkinitcpio.conf if has a new version will be called /etc/mkinitcpio.conf.pacnew and you have to manually edit it with the latest updates, and also keep your modifications to it. Otherwise will not be overwritten.

7

That doesn’t seem to have made any difference.

Rebooted after adding the KMS modules and it locked again. I had to unplug the machine from the wall for 20 seconds and start again to get it to come back.

I have noticed (but this may be a red herring) that it seems to work when I don’t select the Manjaro option on GRUB (i.e. I leave it to select itself). If I hit ENTER on boot then it gives me no login prompt.

This may well be completely coincidental but I thought I’d mention it.

8

@Chrysostomus - can this be investigated somehow? I can’t right now, but could be a thing and maybe you have an idea. Thanks!

@tiefling - can you also run:
sudo update-grub
and check after that if the issue persists?

9

This is a complete Red Herring - Just rebooted to apply a profile change and got a lock up without hitting ENTER on the Grub screen.

Am doing that now - will report back on any impact. FYI - Here’s the output…

Just keeping this live as I’m still monitoring this - I’ve been stuck in Windows world for a while so haven’t seen it in a while. I have some updates to install and no login prompt after updates isn’t uncommon for me so will report back later today.
