--- Comment #23 from Michael Franzl <michaelfra...@gmx.at> 2009-09-04 06:01:49 --- 64 bytes from 81.189.88.179: icmp_seq=2 ttl=147 time=15 days What stands ALS for? I compiled one kernel as you suggested WITHOUT CONFIG_ASUS_LAPTOP and WITHOUT CONFIG_ASUS_ACPI and boot WITHOUT boot parameters. I compiled also a second kernel WITHOUT CONFIG_ASUS_LAPTOP but WITH CONFIG_ASUS_ACPI and boot WITHOUT boot parameters. Result was in both cases identical: 1) Resume from Standby works with maximum brightness, brightness changing afterwards not possible 2) Resume from Memory doesn't work when in console-only, it hangs before coming back. When issued from X11 it does come back, but with brightness controlled by ambient light sensor, brightness changing afterwards not possible. 3) Resume from Disk works with brightness controlled by ambient light sensor, brightness changing afterwards not possible. The reduced brightness is first encountered when the kernel writes the memory onto disk, before switching off. In all cases, after a soft reboot, the reduced brightness is staying. Only after a hard reboot, the brightness is back to maximum. The reason why this reduced brightness is so nasty is because it is done with PWM (Pulse Width Modulation, I think all recent laptops do this). And it's aggressive puling, like 20% on time, 80% off time, and is really noticeable, and my eyes get tired fast, me unable to concentrate any more.
