After upgrading to 8.04 today and to the new kernel 2.6.24, 
my backlight is turned off after resuming from a suspend. I can see something, just the backlight is off.
Switching to a Console with CMD-ALT-F3 and back to X11 turns it on. 

This problem is known with my laptop and I resolved it with gutsy adding DOUBLE_CONSOLE_SWITCH=true to /etc/default/acpi-support, but this does not to work for hardy. 
Laptop: Lenovo Thinkpad T61 with Intel GMA915 graphics. 

Please feel free to ask for some attachements or files or anything that helps. 
Thanks for the good job youre doing.
