More on problems suspending in CURRENT. After the latest round of updates, I tried suspend (S3) again. Again the backlight stayed on, but I noticed one interesting thing that MIGHT be relevant. After I start the suspend, the backlight DOES turn off. But, at the very end of the suspend procedure, it turns back on! Here is the sequence with approximate times: % acpiconf -s 3 Pause for about 1.5 seconds Screen blanks (back-light on) for about 2 seconds Appox. 1 KHz beep Backlight turns off for about .2 seconds Screen turns back on and unblanks Approx. 600 Hz. beep All of this is with jhb's acpi_dpms patch to acpi_video.c (with changes to accommodate recent revisions to acpi_video.c).
