Some hardware stuck at 15W TDP in gamescope-session

Writing this here so we have a place to track this.
@d3Xt3r has this issue and we confirmed earlier today it is not related to https://github.com/ublue-os/bazzite/issues/320

ENABLE_HARDWARE_CONTROL_ON_NON_DECK_HARDWARE
ENABLE_HARDWARE_CONTROL_ON_NON_DECK_HARDWARE
is set to 0 so
/usr/bin/steamos-polkit-helpers/steamos-priv-write
/usr/bin/steamos-polkit-helpers/steamos-priv-write
is disabled, yet the TDP gets set to 15W in gamescope.
They are currently using the dirty workaround from the #320 issue until we can track down the cause.

@d3Xt3r if you could provide
rpm-ostree status
rpm-ostree status
,
rpm-ostree kargs
rpm-ostree kargs
and also the hardware of the affected system it might help to get us started on looking into this.
For now, if anyone stumbles upon this issue, use the workaround provided here: https://github.com/ublue-os/bazzite/issues/320#issuecomment-1725206390

Solution
I can confirm that the fix works 🙂 TDP is back to normal, permissions stay on 644. Tried going in and out of game mode as well as launching different games. This was tested without LACT.

Afterwards I installed LACT and tested - good news is that I can still change the TDP via LACT and the value persists after a reboot. 🙂
