I run the kernel with fbcon=rotate:1 video=DSI-1:panel_orientation=right_side_up \   mem_sleep_default=s2idle No special i915 parameters. Hardware is described here: https://wiki.archlinux.org/title/GPD_Pocket_3 I disected this patch which was merged (backported) for 6.1.23. I currently run 6.1.26 with it reverted and life is good. Without reverting it, when fbcon is switched to show the splash screen (GPD logo with Ubuntu added in on working kernels), the screen remains black (backlight on, but nothing displayed) and nothing happens any more. It looks like something more serious than just blackness, as SysRq or Ctrl-Alt-Del don't do anything. Deadlocking? Best, -- Kurt Garloff Cologne, Germany
