Description of problem: I am using KDE and the brightness of my display panel is too high. I am unable to reduce it using any of the kde utilities. Also the fn-f5/fn-f6 doesn't seem to work Version-Release number of selected component (if applicable): 2.6.33.2-57.fc13.x86_64 How reproducible: Always Steps to Reproduce: 1. Install F13 on Vaio VPCCW 2. Try adjusting brightness with Fn-F5/Fn-F6 3. Actual results: Brightness isn't getting changed Expected results: Brightness should be changed with fn-keys Additional info:
Do you have any directories in /sys/class/backlight ? Could you please also attach the output of the lspci command?

Could you please attach the output of the acpidump command from the pmtools package?
Created attachment 410005 [details] ACPI Dump I coudldn't find pmtools respin for F13 in koji, installed F12 pkg. Hope its ok.
just came across this, http://www.linux.it/~malattia/wiki/index.php/Sony_drivers Are our kernels built with these CONFIG_SONY* flags ?
[envy@localhost ~]$ grep SONY /boot/config-$(uname -r) CONFIG_HID_SONY=y CONFIG_SONY_LAPTOP=m CONFIG_SONYPI_COMPAT=y looks for newer chipset, its a problem :(
Does it work if you use the nouveau driver rather than the nvidia one?
nouveau doesn't detect the display at all!
Ok. From the looks of your system, backlight control should be provided via the graphics driver. Nouveau will do so, so if nouveau's not working then that's a separate bug that we'll have to fix. Unfortunately there's no way for us to add backlight control to nvidia's driver, so I'm going to close this out and maybe they'll get around to fixing their bug eventually.
thank you.
To adjust brightness on Nvidia graphics card (in particular on Sony VPCCW) with Nvidia proprietary driver, try installing nvidiabl (worked for me): https://github.com/guillaumezin/nvidiabl
