Package: light-locker
Version: 1.8.0-3
Severity: normal

Dear Maintainer,

When screen locks on Dell Optiplex 9020 w/latest BIOS, i cannot wake it with keypresses or mouse movements
have to ctrl-alt-f1 to console, then monitor wakes up. If I ctrl-alt-f7 back to grapical console, I get a message about waking up soon - so something is on that screen - but it never wakes.
I have to pkill light-locker in order to continue - then everything works again

I am using NFSv41 home directories on this system
I am also using LDAP for user accounts and kerberos for PW. 
Not sure if that affects this or not

thanks for maintaining this package and for supporting Debian!


Some of this extra stuff may also help: (from alternatives....)

Dear Yves-Alexis,

Thanks for your reply.

I am happy to announce that this bug #972417 disappeared, even if I don't know what solved it.
Bug occurred until Nov 4th 2020, at least.
Bug did not occur from (at least) Nov 21st 2020, and did not reoccur until today.
Thus I'll close this bug report.

For the record let me answer your points:

> The lightdm greeter is on tty8, so try with Ctrl-Alt-F8.
When bug occurred, tty8 remained black.

> With all those bugs already opened and the mess we're already in, why opening
> *yet another one*? Honestly it adds more confusion than anything at that
> point.
Because this bug report was filled against xfce4-power-manager, due to reasons explained in '[ Guilty package ]'.
Other reports that I listed were all filled against other packages. None against xfce4-power-manager yet.
Sorry that it got felt as 'confusing', that was not intended.

I tested when bug still occurred. Results:

1) with current stable kernel: linux-image-4.19.0-12-amd64   4.19.152-1
- Bug still occurred
- I could not find "broken atomic modeset userspace detected, disabling atomic" in kernel log, ie nothing found by
  - grep -ri "broken atomic" /var/log
  - dmesg | grep -i "broken atomic"

2) with old old stable kernel: linux-image-4.19.0-10-amd64   4.19.132-1
- Bug still occurred
- I could not find "broken atomic modeset userspace detected, disabling atomic" in kernel log, ie nothing found by
  - grep -ri "broken atomic" /var/log
  - dmesg | grep -i "broken atomic"

Regards,
Franck
