How I would like to use a desktop switcher

Posted 11-12-2012 at 08:01 PM by Skaperen
Updated 11-14-2012 at 04:51 PM by Skaperen

I currently use the compiz desktop switcher. It's also what is known as a "compositor", but I really don't know what all the functions are that it needs to perform. Clearly among them is switching desktops. So I guess it places windows from some sets of windows (and other GUI objects) on to and off of the screen as needed.

How compiz is working is that is displays some effect on the screen to show how you are doing switching. Some people like the cube effect where when...

Major disk trouble DRDY ERR and UNC error

Posted 11-07-2012 at 11:08 AM by error_401

Just happened:

Got a nasty error on my laptop running Debian Squeeze. Unable to boot further than initramfs with errors preventing the file system from mounting.

Nasty bugger. Seems to be a bad sector on my HDD. Causes several attempts to read and finally fails with
DRDY ERR and subsequent UNC error triggering the errors:
unable to mount rootfs etc.

Now trying with the installer CD-ROM in recovery mode. A bit nasty as I have unsaved data...
