I suspect it is related to the framebuffer. I have killed X and tried it from the console, but it still crashed when it resumed. So killing X, framebuffer and whatever else it chokes on I think would not be very practical, unless there's a fix/script that works for this? > > PS.

Which function would you associate with the lid switch - not that it matters with this laptop. When I try to put it into standby it stops the disk alright, but the screen turns really bright within a secodn or so (I fear it may burn out if I leave it for any length of time). I tried to use radeontool light off, but it doesn't seem to work (the screen turns on again when in standby). -- Regards, Mick
