Is it possible to take a screenshot of the logon screen...?

I have looked this up on da web but not with any success.

As I have made my own logon screen backgrounds and would like to take screenshot of them with the user & password panel as I will also be editing the panel as well..

Thanks

I've never found a way.

It's easy to take screen shots of almost anything when you run in Virtual Box. You could take a snapshot of your system and then boot the iso you created in Virtual Box. This is how we generate screen shots of the bootloaders and the early boot process.

Another approach would be to set the console frame buffer to a decent resolution and then use the fbdev driver for X. This should put the X-windows system in a framebuffer. From there you can run fbgrab in another console to get the screen shot. I tested this on a 1920x1080 laptop running antiX live and it worked. I got a full screen screen shot of the display manager (SLiM). As root (in another console), I ran the command: This caused it to sleep 10 seconds before taking a screen shot of tty7. The main difficulty may be getting a good resolution in the framebuffer. I did this live using "nomodeset xorg=fbdev". On that laptop I was able to use the F7 Console menu to get the full 1920x1980 resolution of the screen.

I tried using "scrot" to do the same thing without having to use fbdev but I wasn't able to get the right permission. Once the user was looged in I could get a screen shot from a virtual console with:Perhaps it would have worked with the display manager if I tried running as root.

Damn my draft did not save..
I have tried two & three will post tomorrow need sleep work morning..

I've used the 2nd approach that I found here ("Better but slightly complicated way of taking screenshot of login screen in Ubuntu and other Linux"): https://itsfoss.com/screenshot-login-sc ... ntu-linux/

But my notes on this are over 3 years old -- did it with Debian Jessie (Xfce). I'll have to test it out again and see.

Tried it in one of my Arch installations just now:



My notes on this are missing a few steps, though -- I'll have to clean them up before I post them here, unless somebody else beats me to it (or finds an easier approach for MX).

Okay, I've tried this again with Debian Stretch Xfce, should work in MX (but I'm using sudo instead of su). Here's what I did:

- First, made sure imagemagick was installed (apt search imagemagick).

- Created the file ~/screenshot.sh with the following contents:
- Made the script executable.

- Logged out of the session.

- Ctrl-Alt-F2 to get to tty2.

- Logged in as normal user, then ran the following:
That took me back to the login screen and took the screenshot after 5 seconds. Ctrl-Alt-F2 to get back to tty2.

- Next, I ran:
- Ctrl-Alt-F7 to get back to the lightdm login screen. Logged back into Xfce. Copied the screenshot from /root to my home directory with:
Could have simply used the mv command, but since I didn't, went back and deleted the screenshot from /root:
So here's my (boring) lightdm login screen in Stretch Xfce:

That method also works for me.


This is the script I used (I changed it to one command per line instead of all strung together, also added the shebang which wasn't mentioned)
