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
(<a class="moz-txt-link-freetext" href="https://bugs.freedesktop.org">https://bugs.freedesktop.org</a>) 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.<br>

I do not know what I am doing, so just tell me what to try. <br>
