I think I understand the issue well enough to sum it up nicely, so if no
one objects, should I just go ahead and file a bug report? If we're about
to dump Slim for lxdm or lightdm or whatever, I needn't bother, but if we
plan to keep Slim for release 1.0, I'd like to see the issue addressed.
Looks like an easy enough thing to fix - all we need is to change the login
screen graphic to document the available options. I think I can write up
the proposed documentation change myself and then submit it.

I have not yet used Devuan's bug reporting system - I just looked at the
site now and I signed up for a git account. This this is a Slim issue,
should I report it here:

https://git.devuan.org/devuan/slim/issues

Please tell me if I'm doing this right. If no objections within next 24
hours, I'll proceed.

Thank you, and apologies for my inexperience with git.

cheers,
Robert
