It is possible that when you close the lid the contents of memory writed to the disk and reading this few hundred Mbyte - on my laptop KDE is eating ~800 Mbyte memory, the hungry Beast! :) 1) It doesn't matter how much KDE takes - the RAM is always written and read completely, not partly. 2) Those 800 MB definitely include a lot of apps running. What does top/free say immediately after you booted the machine and logged in (bootet from the state of being really switched off, that is)? Mine says about 240 MB (32 bit). Compared to KDE3, KDE4 takes longer here, as well. But not that long. The laptop's screen goes off and on once or twice, which may account for most of the delay. And the mouse pointer doesn't follow the mouse for a second or two. I have never measured it, but I guess it takes around about 6±2 seconds from switching on to seeing the password screen. (Provided that I move the mouse right away to make KDE show the screen). -- Gruß | Greetings | Qapla' I wish my lawn was emo, so it would cut itself. signature.asc Description: This is a digitally signed message part.

I'm thinking maybe you have hardware that is taking ages (or is just unreliable) to wake up and resume, and kde depends on that hardware. Video drivers and wireless ethernet comes to mind. -- alan dot mckinnon at gmail dot com

It takes up to 45 seconds for the screen to wake up! The PC starts up immediately, but the screen stays blank. In MSWindows, the screen becomes alive within seconds. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
