A friend said, his laptop's battery is very weak after Ubuntu failed to suspend after lid closed. He then quickly put laptop to backpack and did not realized, that laptop is still working.

I'm wondering how to make Ubuntu beep when lid is closed for N minutes, but system is not suspended and temperature increased up to a danger zone?

UPDATE: Question here is how to make it warn me that it failed to switch off. If I'll be in a hurry I'm sure I will not want to wait 5s until I'll be sure it went off. I'll be closing the lid, throwing laptop into backpack and running. :)

Does anyone know how to avoid getting this message:

Assuming drive cache: write through

Which is showing up after performing sudo shutdown -r now.

I restarted remotely but the computer did not restart. And I can't restore my remote connection to it. I want to be sure that it won't happen again. When I physically approached the computer and turned on the display, I found 3 lines saying:

Assuming drive cache: write through

All those messages were because of my sdd disk. Later I checked and found that sdd is my external USB 1TB disk.

Any ideas on how to prevent such situations in future?

My laptop's video card is malfunctioning. I have Ubuntu 10.10 Desktop. After typical boot up, it restarts, but it's working fine in recovery mode.

There is my other solved question here: How to enable SSH server in recovery mode?

I don't want my Ubuntu run in recovery mode. I want everything start normally, just without video card. I'm expecting it to run like a remote server.

I have a laptop with broken video card. It has two operating systems installed - Windows 7 and Ubuntu 10.10 Desktop Edition.

It has GRUB to manage which operating system to boot up. Windows is default OS. And Windows fails to boot up without video card. I'm checking with ping to the ports which are shown as used by DHCP in my router.

Normal boot of Ubuntu also fails and it restarts after a while. But when I choose (blindly, but checking HDD indicator and by counting button presses when GRUB menu appears) to boot second option of Ubuntu (rescue mode) it starts and I can ping it. But when I try to connect to it through SSH, I'm getting "connection refused" error from putty.

I've took out HDD from my laptop already and inserted it to WD Passport case so now I can connect it to other computer to edit configuration files.

How can I check if SSH server is working? How to enable it in rescue mode? Or better, how to disable video card to be required while booting Ubuntu in normal mode?
