Leann, What works in Intrepid is the workaround. Dimming and Fn keys are not implemented in Intrepid.
** Changed in: linux (Ubuntu) Status: Fix Released => In Progress ** Description changed: Fn keys don't work for dimming the screen, though they do stimulate the sonybright.sh script. xbacklight works if the notebook has an Intel 965 (x3100) display adapter, but is subject to bug #176888 (won't work on Hardy, bad XRandR setting). There is no known method for setting the LED backlight on newer Vaios with nVidia GeForce 8 series adapters, though it is possible to pseudo- dim by making the LCD blacker (this unfortunately doesn't help with power-saving). There are 2 problems here: 1) The Vaio's LED screen is really very bright when burning at 100% and is hard to look at for any period 2) Battery life suffers Pretty much all the newer Vaios (2007 onwards) have some combination of these graphics adapters so this bug should be widespread (and much appreciated when fixed!). A couple of script solutions have been proposed in this bug report; please feel free to hack and make suggestions. One solution for notebooks with Intel 965 display adapters is to install xbacklight: ]$ sudo apt-get install xbacklight Then add these 2 lines to /etc/rc.local (or just execute from the command line): xrandr --output LVDS --set BACKLIGHT_CONTROL native /etc/init.d/acpid restart And edit /etc/acpi/sonybright.sh so that is contains only this: #!/bin/bash if [ "x$1" = "xdown" ]; then xbacklight -time 100 -steps 10 -dec 10 2>/tmp/sonybright.log elif [ "x$1" = "xup" ]; then xbacklight -time 100 -steps 10 -inc 10 2>/tmp/sonybright.log else echo >&2 Unknown argument $1 fi + + Please note that this will not affect brightness on nVidia 8 series + adapters, just Intel adapters. -- unable to adjust screen brightness on recent Sony Vaio notebooks https://bugs.launchpad.net/bugs/173652 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
