[SOLVED] Quit button login screen not working (on tap)

[rob2701]

Hi everyone,
Just installed Mint 19 Cinnamon on a laptop and noticed that on the login screen the Quit button does nothing (the one in the top right).
Kernel: 4.15.0-30-generic x86_64 bits: 64
Desktop: Cinnamon 3.8.8
Distro: Linux Mint 19 Tara

Mint 18.3 Cinnamon > click button "Quit" shows options supend / hibernate / quit
Mint 19 Cinnamon > click button "Quit" does nothing (shows tooltip text "Quit"

Is this a know issue, or does anyone know the reason and/or fix for this?

Thanks in advance!

Not a known issue that I know of. Did you verify the integrity of your installation medium before installation? Something might have been corrupted. Try to launch the dialog manually from a terminal, pay attention to potential error messages:

Code: Select all

cinnamon-session-quit --power-off

and/or try to reinstall it:

Code: Select all

apt install --reinstall cinnamon-session

Also Alt+F2 brings up an dialog to run commands, type r followed by Enter to restart the cinnamon process, that might fix it.

[rob2701]

Yes, integrity of flash drive iso content was checked before installation.
Are we talking about the same thing? I am talking about the button on the login screen (top right of the screen _before_ logging in).

The quit button after login works just fine (bottom left on the menu).

[rob2701]

sorry, forgot to add:
after logging in running cinnamon-session-quit --power-off from a terminal works excellently also

Apologies, I had read right over that. The quit button on the login screen should work just fine as well, there is no issue reported with it. So maybe try to re-install the package responsible for that one:

Code: Select all

apt install --reinstall slick-greeter

[rob2701]

thanks for the tip! just did that, but unfortunately it did not change the result.
after logout, just the tooltip.
after reboot, just the tooltip

I know it's not the end of the world, it's just annoying

[gm10]

Strange. On the login screen, there's also an accessibility menu item. Does that one show a menu when you click it? It's built the same way as the shutdown menu.

[rob2701]

Accessibility, keyboard, time and power button on the login screen only show the tooltips, so all have the same behaviour. They cannot be clicked and show no menus when clicked.
Tried 2x to reinstall cinnamon session, but that did not make any difference either.

Thanks for the help so far!

[gm10]

Ok, so the MenuItems are handled by GTK3. Same as the MenuBar though. Thus I have little hope for this one, but try it, anyway:

Code: Select all

apt install --reinstall libgtk-3-0 libgtk-3-bin

Unless that actually works or someone else comes along with a good idea, you could submit a bug report here:
https://github.com/linuxmint/slick-greeter/issues

[rob2701]

Alas, no change
Strange thing is that in 18.3 I can hover over the icons and the menu pops out, but on 19 the icon needs to be clicked for just the tooltip to pop out.
Need some sleep now, so more hunting for the cause tomorrow.
Thanks for your efforts so far.

[gm10]

The click part is normal though, that's how it behaves for everyone for all I know (also in 18.3 using lightdm btw).

If all else fails, I would do a clean install 'cause sometimes things go south-east.
Have you checked into the BIOS settings for anything unusual?
I had one laptop doing weird stuff like that, so I replaced the 1T HDD with a new 1TB HDD, did a clean install, and presto! Back in the saddle again.
I use that old 1TB HDD as a backup drive, since it seems to work fine in that capacity, with no errors. Go figure.
Good luck.

[rob2701]

Funny thing is: this is a very clean install (4 hrs old). On a brand new Zenbook with brand new SSD.
BIOS was checked beforehand. Only change was for UEFI secure boot, first disabled then after installation enabled with sudo mokutil --enable-validation.
Will enter this on Github later.

Can you post back the output of....

cat /etc/lightdm/slick-greeter.conf

&

gsettings list-recursively x.dm.slick-greeter

This is just to check if there is something funky in your settings that could be causing the issue.

[rob2701]

sorry, took a while as I decided to redo a complete clean install just to make sure, only Secure Boot disabled, nothing else changed. Same results.
used Linux Mint 19 Cinnamon 64bit v2 iso, media integrity checked.
I have entered the issue on Github this morning.

slick-greeter.conf only gets written if you modify the settings via the Login Window app, and the gsettings don't matter at all since they are user-specific, only modifying the defaults would matter and those are system files.

One thing we did not try actually is if you boot from the live USB, does it work there? If it does work there we can keep hunting for what might have been modified after installation, otherwise it's something weird... you did say you verified the integrity of the files on the USB successfully, after all.

[rob2701]

Live cd has no login screen as far as I recall?
So can't check that...

But doing log out on live cd and then checking the buttons: same result as installation, no dice...just the tooltips

Must be something which wedged itself steathily in the v2 iso?

Works fine with the v2 iso for me. So either it's some weird hardware interaction (and I really don't see how it could be) or something is wrong with your usb. To confirm again, you did the integrity check from the usb's boot menu? Or do it afterwards, while booted from the usb navigate to the USB's mount folder and run md5sum -c MD5SUMS.

If you didn't already, you should add the info about it failing on the live USB to the bug report, that's crucial information.

[rob2701]

yes, verified integrity from the ISO boot CD (USB) menu
checksum OK

Will try to download anew from another mirror and put it on another flash drive, then do a reinstall and report back

Nah, if the checksums check out there's no need to redownload or even to use another USB I think. At best put it in a different USB port (if you got it in USB3 put it in 2 or vice versa, that sometimes matters).
