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 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!). I've tried hacking xbacklight into sonybright.sh but I'm not very competent at shell script.

One solution for notebooks with Intel 965 display adapters is to add these 2 lines to /etc/rc.local :
xrandr --output LVDS --set BACKLIGHT_CONTROL native
sudo /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

Leann,
What works in Intrepid is the workaround. Dimming and Fn keys are not implemented in Intrepid. |

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 |

Leann,
What works in Intrepid is the workaround. Dimming and Fn keys are not implemented in Intrepid. |
I'm changing the status of this bug back to a "Triaged" state. The reason is that a bug in an "In Progress" state should be assigned to a specific member of the kernel team to indicate who on the kernel team is working on the bug. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. I think this bug may inadvertently be getting overlooked since it is in an In Progress state but a specific member of the kernel team is not working on a fix. Thanks. |
