I tried $ lshal | grep system.hardware.vendor I got system.hardware.vendor = 'Sony Corporation'
$ lshal | grep system.hardware.product I got system.hardware.product = 'VGN-SR29VN_S' Then in the file /usr/share/hal/fdi/information/10freedesktop/10-laptop-panel-hardware.fdi I added the following <match key="/org/freedesktop/Hal/devices/computer:system.hardware.vendor" string="Sony Corporation"> <match key="/org/freedesktop/Hal/devices/computer:system.hardware.product" string="VGN-SR29VN_S"> <merge key="laptop_panel.brightness_in_hardware" type="bool">false</merge> </match> After reboot, I still can't change the brightness. Is it because my laptop does not support the brightness in hardware, and the problem comes from somewhere else ? -- Cannot adjust brightness in Lucid Lynx https://bugs.launchpad.net/bugs/555122 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
