Same behavior on fresh Linux Mint 19.2 install. It's a pain to unlock screen. Input field is unresponsive and it takes too much time to type password characters.

Same here on a pristine 19.2 install. I've upgraded kernel to 5.3.1 and it didn't help. Lock screen freezes and its very slow and unresponsive when trying to enter my password to unlock.

Exactly same issue here on both machines I have (Asus I5 laptop and Intel workstation) after upgrading from 19.1 to 19.2. Lock screen freeze password entry is extremely slow and unresponsive after waking up (It doesn't happen at initial boot up). Specs for both machines shown below, the workstation has NVIDIA 1080 Ti GPU, the laptop only has Intel integrated graphics, but both machines have exactly same issue.

Re: Lock screen UI freezes in Cinnamon 19.1

It might be helpful of users suffering from this issue consistently could run some trouble shooting steps and post the output. if that reveals any useful info hopefully someone can post a bug report for the devs.

Open a terminal and run

Code: Select all

cinnamon-screensaver-command -e && cinnamon-screensaver --debug
Leave the terminal window open or minimised and either go about your business leaving the screen to lock naturally or lock it via your preferred method.

When you have experienced the issue, but got unlocked then review and post the output of the terminal window running cinnamon-screensaver --debug

Sample output from a working lock / unlock on Cinnamon 19.2

I can reproduce this problem but only in very specific circumstances - after suspend with 2 users both logged in whilst suspended. Will follow my own advice a little later and see what the --debug output is in that scenario.

Re: Lock screen UI freezes in Cinnamon 19.1

Post by Yfrwlf » Sun Oct 06, 2019 12:47 pm

I'm running Mint 19.2 and what I've discovered so far is that this seems to happen when Thunderbird pops up a calendar event notification window behind the lock screen. When that happens, the lock screen appears unresponsive and only shows the first star or no stars when typing in the password, but it is still functional and if you type in your password and hit enter, it will unlock the desktop like normal.

Has anyone noticed if this is happening due to windows popping up behind the lock screen as I'm describing here? I'm not sure if notification pop-ups cause this too or not, or if it's just my Thunderbird calendar event windows causing it.

No hibernation or suspend is enabled.
I am not sure, but it might be happening when I receive a notification while the screensaver is active.

Re: Lock screen UI freezes in Cinnamon 19.1

I'm having problems getting out screen also - the problem relates to getting the password prompt to unlock the screensaver to appear and remain 'stable' such that it can then be used to enter the password.

Sometimes I have to hit the escape button multiple times to even get the machine to react. Then, prior to the unlock password being entered, the system will flash up / show the current desktop contents, then remove that (I think it goes dark again, then sometimes continue through a cycle like that. It's a bit like watching the terminator after having been dropped into the molten steel at the end of T2 ;)

I think that the cause mentioned re notification pop-ups having something to do with it aligns with what I'm seeing also. In my case I don't use any email client, but I have noticed pop-ups something similar to 'Wireless Connection Disconnected' or 'Wireless Connection Established' (or something like that) appearing during these 'flashes'.

So perhaps it's a combination of power management turning the Wifi off, and something in the desktop manager not liking the resulting popup?

Hope this helps.

The popup message is 'Disconnected - you are now offline' - with a Wifi logo appearing in the popup

I've tried to reproduce notifications when screen locked causing an issue and haven't been able to.... :roll:

I've since checked hibernating the machine with Wifi disabled beforehand, and coming back out of hibernation/screenlock was a breeze compared to previously, so this is something I'll continue doing until a patch fix or update is available.
I've had a look under the Power Management utility but couldn't see anything that relates to Wifi, so I'm not sure where else or how system behaviour in this area is managed (and I'm happy to leave to others who know more :)
Hopefully this info might be helpful though.

This happens for me every time I wake up from suspend (lock screen unresponsive but I can unlock if I type my password correctly). I tried disabling wifi and closing all applications before suspend, but it still happens every time. Happy to try and grab some logs, but would need instruction on how to do so.
