Comment 28 for bug 146710

Same issue with Samsung R700 c/w Nvidia 8400M

backlight okay with "nv" driver, but that's not as fun with compiz...

have used SonniesEdge's script [ see above at : https://bugs.launchpad.net/ubuntu/+bug/146710/comments/24 ]

which works sufficiently well for me to a) praise SonniesEdge b) live with it until the driver is fixed

the acpi seems to timeout on shutdown after running that script, but i haven't determined whether that's just a co-incidence and that i haven't otherwise broken something
