Black screen on first Game mode boot
I just reinstalled bazzite-deck on my LCD Steam Deck using an ISO from 2024-08-10. Everything was going fine, it booted to desktop mode and displayed to my multiple monitors via a dock. I ran topgrade before rebooting.
On the first boot where it would go into Game mode, the backlight kicks on but the screen stays black.
I was running bazzite-deck:stable with Game mode just without issues before the reinstall.
