The Xorg driver works well except that when I close and reopen the laptop

display. Can I manually turn the light on? If so how? I don't see any
activity on related bugs since 2010.
I have had to switch back to the proprietary fglrx driver despite its
problems because being able to close and reopen my laptop is higher priority
than the improved display characteristics of the Xorg driver.
What kernel are you using? Does manually adjusting the backlight
controls after resume fix the issue? Are you using the acpi backlight
interface or the radeon specific backlight interface? Open a bug
(https://bugs.freedesktop.org) and attach your xorg log and dmesg
output.

Ubuntu 12.10 with kernel 3.5.0-23-generic. I am just running with
whatever configuration the Ubuntu "Additional Drivers" graphical tool
activates. I do not know what that is. I have no idea how to manually
adjust the backlight controls, but the light is completely off, so I
think that would be pointless. I tried using "radeontool light on" to
turn the light on, because I could see that command being issued by the
lid.sh script, but that did nothing. I am not familiar with the
capabilities of the acpi interface. I just want to turn the light on!
I would not be asking if I knew what to do. I do not believe there is an
intrinsic problem that needs a bug fix. The actual resume seems to be
working fine. For example I can telnet into the resumed system. I
think this is just a configuration error in Ubuntu for this particular
hardware. For example I get exactly the same behavior if I switch to
the fglrx driver, using the "Additional Drivers" script, and then forget
to run the "aticonfig --initial" script. So I am confident that all I
have to do is find the right command to turn the light on.
I do not know what I am doing, so just tell me what to try.
