@lexi #uswsusp to the rescue~

Most laptops I had came with buggy firmware implementations anyway.

Wow, some years ago I gave up on hybrid #suspend with #uswsusp and #s2both on #debian #linux because my HP G200 laptop was not whitelisted with uswsusp. I just found out that uswsusp is deprecated since 2020 and hybrid suspend is now natively baked into the #kernel. Works like a charm in #debian11 with #kde on #wayland. Even works from the command line with "systemctl hybrid-sleep".
(You are using #systemd, aren't you? :-)

Who can confirm hybrid-sleep for #gnome, #x11 and everything else?
