Funny, I was puzzling over this last night, before I looked at this thread.
On my NEC VersSX notebook there does not seem to be a screen blank key combination. Instead, I had success with FN-F4 ("display") which switches between external monitor, LCD, and both at once. The LCD screen can be blanked by switching to just the external monitor (even if there isn't one).
Unfortunately, if X is running, the screen gets curdled into garbled repeating columns. Any idea what is going on?
What normally does screen blanking in non-X mode? Can it be taught to turn off the backlight (I don't think it does so now)?
On another topic, I find that the regular sync calls from update keep my system from leaving the disk off for a reasonable amount of time (at least I think that is what is going on). I suspect that if there were an option to suppress inode flushing if the only change were to the access time, these syncs would not actually require disk activity. Is this guess right? Is there a way to specify that sync should behave this way? Would it be easy to add?
