Cannot swith to gaming mode

Hello, I have a very persistent issue where my bazzite-deck installation always boots to Desktop Mode instead of Gaming Mode. We have exhausted all troubleshooting steps and it seems the gaming session is crashing on startup. System/Hardware Info: - Device: ADVAN 1301 / ARP31B-070P2-XCL - CPU/GPU: AMD Ryzen 7 7840U w/ Radeon 780M Graphics What we have already tried: - Successfully rebased to bazzite-deck:stable. rpm-ostree status confirms this is the active image. - rpm-ostree reset reports "No change", confirming a clean system base. - Found the correct session name is plasma-steamos-oneshot.desktop. - Manually created /etc/sddm.conf.d/autologin.conf to force the plasma-steamos-oneshot.desktop session. - Disabled the proprietary Broadcom wl driver (which was tainting the kernel). - Disabled the hhd@Allueto.service because it was showing crashes in the log. Even after all of this, the system still falls back to the Plasma Desktop session. This appears to be a deep bug or hardware incompatibility. Here is the full boot log from a failed attempt: https://0x0.st/Kuic.txt Thank you for any help you can provide.

I had a look at your log. It doesn't look like it's even trying to boot into game mode.

This is the line on my bazzite-deck image

I'm wondering if you had an autologin setup before the rebase that is interfering with logging into gamescope If you put the text bellow in /etc/sddm.conf it should give you a login screen where the default is gamescope mode but you can choose desktop mode if you like from the list of sessions 
[Autologin]
Relogin=false
Session=gamescope-session.desktop
User=
[Autologin]
Relogin=false
Session=gamescope-session.desktop
User=
If you fill in the user it will auto login but you can log out to and then "log in" to any mode you want (since Relogin is false)
