Put a custom background on xlock

[WoPr]

Hi all!

I have a question about xlock. I read the entire help and I don't find anything useful for me.

I would like to know if there is some way to put a custom background with xlock. I need to lock the desktop of a system, but showing an image. In other words, if you put the command:

xlock -mode blank

I want an image instead a black screen.

Thank you and best regards,
WoPr

Hi!

Any idea? or maybe another way to do it?

I need to lock the desktop with a password, but I need a custom backgroup and a custom message.

Thanks in advance
