Hi Wouter, Thanks for your response. Sorry for bringing KDE into the picture. Now let's drop it and look at the pure userspace level, if you don't mind :-)
So here's what I get: *With nothing (blacklisted sony_laptop): *No way to set brightness, as far as I know. *With custom sony_laptop module: *cat /sys/devices/virtual/backlight/sony/max_brightness => 8 Then I can echo the value 0-9 to /sys/devices/virtual/backlight/sony/brightness So I have 9 brightness levels. *With original sony_laptop module (Kernel 3.2.6-gentoo): *cat /sys/devices/virtual/backlight/sony/max_brightness => 247 !!! Then I can echo the value 0-247 to /sys/devices/virtual/backlight/sony/brightness So I have 248 brightness levels!!! See? There's a huge difference between the stock sony_laptop and the Vaio Z improved one... Is there a way to fix this regression?
