What pk says is quite normal in my experience. This laptop is a Dell Precision, from pressing enter on the grub screen to kdm showing on the screen is 3 seconds, another 4 seconds for KDE to appear and start responding to mouse clicks. >From power-on to the grub menu showing, that's about 30 seconds. The first 8 or so is a ... blank screen ... then I get the Dell logo, followed by another 20 seconds or so where is does $SOMETHING. Server hardware is even worse - the R[357]* series can easily take 4 MINUTES to get through all the various BIOS thingies. Bi-monthly maintenance reboots get scary, 4 minutes is a loooooooong time when you're flying blind on a critical machine that's physically on the other side of town :-) -- Alan McKinnon alan.mckin...@gmail.com
