Worth noting that this is also happening for a friend who is on SteamOS. Please take a look at this, I literally cannot take screenshots anymore.
Im on bazzite with the same issue, guide chords no longer work on steam controller. Pressing guide trigger no longer clicks mouse however pressing the right trackpad does work, i cant take recording clips or turn of controller or any of the other chord shortcuts shown in the controller layout
FWIW I had the same issue but it started working again recently on Arch Linux, KDE Plasma 6.6.6, Wayland.
It started working when I fixed my XDG Desktop Portal services, which prevented me from sharing my screen using e.g. Discord or simply https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/.
In my previous installation I have tinkered with my portals which broke the services. It broke when I migrated from dwm/X11 to KDE/Wayland, another reason I suspect this issue.
Not sure if related, but stopping the user Systemd portal services crashes Steam right now when I use a Guide Button Chord to pause a video:
systemctl --user status xdg-desktop-portal.service plasma-xdg-desktop-portal-kde.servicesystemctl --user stop xdg-desktop-portal.service plasma-xdg-desktop-portal-kde.servicesystemctl --user status xdg-desktop-portal.service plasma-xdg-desktop-portal-kde.servicesystemctl --user status xdg-desktop-portal.service plasma-xdg-desktop-portal-kde.serviceAnything systemd and Desktop Portal is black magic to me, not sure what additional scenarios I can test out. Can't share logs right now though.
Might be a different issue but for me what fixed it was just guide+select, screen reader was enabled and when its enabled it blocks chord buttons, pressing guide+select toggles it. I heard someone made a script that makes sure its off on boot but mines stayed off so far
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
Guide Button chords in Steam Input have largely been borked. On Steam Deck, you can no longer use the triggers for mouse clicks anymore, the keyboard and magnifier can also no longer be used.
On DualSense, this is also true, with Guide+(SOUTH) no longer bringing up the Quick-access menu. Previous Steam builds had borked the use of chords on external controllers, with the keyboard not being usable and the triggers and bumpers being flipped.
