Black screen when locked, no log in prompt present #424

I have exactly the same problem. |
|
I can confirm this issue on two different systems with Linux Mint 21.1 I can also add that if you move the mouse around, you see the mouse pointer change from an arrow to the text cursor when the pointer is over the invisible text field. |
|
hi guys, any fix for this? I have the same problem but for me, I have to open any window to see the login screen (if there is no active/open window in my current workspace, the login screen goes blank with only the pointer visible) |
|
The flicker/display changes when using fractional scaling should have been fixed in 5.6. For the missing unlock dialog, can you guys try: This will leave the screensaver always running (usually it exits after 30s if unlocked). See if the blank screen issue occurs while that's going. Thanks |

@mtwebster hi there, the last command worked like a charm but as soon as I killed the process |
|
I'm getting this too, and my syslog fills with the following python traceback every time I restart |
|
I also get a bunch of these: |
|
Hmm, it seems to start with this: |
|
@jonorthwash Is that version 5.4.5? Can you try to reproduce this from the terminal as I described above? Thanks |

I have the same issue; cinnamon-screensaver v5.6.3, Linux Mint 21.1. It's somehow related to the fractional scaling option. These are the tests I performed:
I have two monitors, one is set to 125%, the other to 100%. However, this doesn't seem to affect the results in any way. The behavior with two monitors is the same as with one monitor, as long as at least on of them is set to anything other than 100%. |

I have the same issue on a 17 inch laptop. Zoom set to 100% -> wake up from suspend -> normal login screen
Zoom set to 125% -> wake up from suspend -> black screen w pointer, but can blindly enter password

@d-adamson re: resolution. That's just how fractional scaling works - 1920 * 2 / 1.25 = 3072 px. |
|
same problem with me |

Hi, silly question: |
|
@mtwebster Just tested it and it doesn't seem to matter. The problem remains. |
|
I noticed too that the black screen issue occurs any time that I have no windows focused (so everything minimised to the taskbar/tray, or no programs open at all). Then, either locking manually or locking by timeout causes the screen to be black when resuming. I'm using 150% fractional scaling, Linux Mint 21.1, on a 1920x1080 display. I'm also able to log in by blindly entering the password, and the cursor is still visible when moving the mouse. |
|
@edsml-hmc122 did it happened in 100% scaling too? |
|
@budimanaa No, interestingly I only get this issue when the fractional scaling factor is not an integer, so 100% and 200% work fine, whereas 125%, 150%, and 175% give the black screen. |
backup-locker window. Since Muffin 5.4, the restacking code in cs-gdk-event-filter-x11.c does not always work properly when either (unredirected) window is handling an event from the other. Now, the backup window will be realized but unmapped while the main window is visible. ref: linuxmint#424
Nope. It's 5.4.4, which is the latest version my apparently very stale Debian mirror has in sid... (Okay, I'm gonna switch mirrors and upgrade now...)
This is the output I get: https://bpa.st/JHHAI |
Okay, I'm now on 5.6.3. Similar issues. At least I see a cursor now when it's locked, but still no login dialogue or anything else—just a background image.
Now I get this traceback once on locking: And then this a whole bunch: The full output of |
Both are override-redirect and ignore stacking. Under some conditions, the backup locker could end up on top of the screensaver, even though the screensaver behaves correctly and is still usable. Changing window types to get better control isn't a good idea, as everything still needs to work properly with or without compositing (cinnamon running). Avoiding painting the window until it's needed steps around the issue, whether the backup window ends up above or below the screensaver window. ref: #424 ref: linuxmint/cinnamon#11632

This worked for me: In Screensaver, set "Delay before locking" to "Lock immediately". |
Issue
Black screen when locked, no log in prompt present.
Steps to reproduce
Ctrl+Alt+(lowercase) L or Click Lock Screen in the menu
Expected behaviour
The log in prompt should be present and I normally also see my background.
Other information
I had issues before this update with fractional scaling. It was reset to 100 % when unlocked. The screen also flickered when locked, showing desktop content. I sometimes also temporarily lost menu items. I did not try to update the driver, I decided to wait for this official release. Those issues are fixed in this update, at least for me.
Edit: If I let it lock itself on timeout, it also works as expected.
