Public bug reported:
Backlight Adjusting doesn't work for linux-image-6.1.0-16-generic.
My laptop is under `Software Rendering`, after I upgraded Ubuntu 22.10
to 23.04, the brightness adjusting is unavailable and my monitor is much
bright. However I change the Kernel to `linux-image-5.19.0-35-generic`,
the backlight adjusting works normally,
The `lshw display` information:
