            Bug ID: 220554
           Summary: Display powers off after every update.
           Product: Drivers
           Version: 2.5
          Hardware: ARM
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: vicencb@gmail.com
        Regression: No

The behaviour happens since 6.17. Tested on rc2 and rc5.
It does not happen on 6.16.


The platform is gru/kevin (arm64,RK3399) with the Panfrost DRM driver.


When it boots in console mode, the blinking of the cursor keeps the display on.
If it is turned off via /sys/class/graphics/fbcon/cursor_blink, then the
display briefly shows each key press presented on screen for less than one
second and then powers off.


When starting the graphical mode (wayland), if there are no applications
drawing on the screen, the only way to keep the display on is by continuously
moving the mouse.
