# Lamba Stack installation issue

## post by julienamplisim on Mar 5, 2025

Hello,

When installing Lambda Stack on a Desktop, I’m asked to select a display manager but I’m not able to choose one (between sddm and gdm3) and select OK in the editor. I tested TAB and several other keys but it did not work. Any tips on that please?

Thanks in advance

Hi,

Are you using the guide here:

Or here?:

If the former, try the latter from our docs site.

If the latter, we’ll likely need you to open a ticket with us, here, if you haven’t already:
