I'm in very serious situation. I use Ubuntu 10.10 on my Acer Aspire One netbook. Today it suddenly froze when I was working on something important. It happened after RAM memory and swap became totally full for an unknown reason (they were partially full before).
The mouse and a screen are frozen now, but the hardware seems to be still working: the network and hard disk LEDs are blinking from time to time, but the keyboard is probably not responding. An external USB keyboard doesn't work, although the USB port is giving power.
I know it's a hopeless situation, but maybe there is a chance to save data from swap and RAM if it is still there. I'm thinking about hibernation or getting RAM contents to an external hard disk in some way before I reboot (if it's possible). I'm really desperate, so I would do almost anything. What would help? I would appreciate any kind of help.
