Hi!
I'd suggest to back up your home directory (do not forget the hidden directories) to some external media (USB hard disk, DVD, whatever). This will back up the files and also your preferences...

Boot from LiveCD (you have one, once you've managed to install Ubuntu, don't you?), install GRUB afresh

Looks like the bootloader is misconfigured.
In a similar situation, I ran
sudo update-grub and it found Windows loader and added it to the boot menu.

Unix shells usually show $ in the end of command prompt for an ordinary user, and # for the root user (try "sudo su" and see for yourself). So, "# find " is "find" run by root.

Flags starting with -D tell preprocessor to Define a macro. -DSSE_SUPPORT means that SSE_SUPPORT will be defined. It is usually used for conditional compilation, e.g.

#ifdef SSE_SUPPORT

Is it critical for you to use en_US locale? I remember I had week starting from Monday with en_GB.

cal -m displays a calendar with Monday as the first day.

Hi all!

I'm having a microphone trouble on my Fujitsu-Siemens Lifebook S7210. Neither internal nor external mic appear to work in Xubuntu 12.04. On Ubuntu 10.04 installed before everything worked...

Hi The_Lunatic!

Did you launch QtiPlot from terminal? Some information about the error can be recovered from the terminal output.

Hi!

Can you see and mount your NTFS partitions in Disk Utility (can be launched from Dash)?

I think it's just power saving. I have Intel Core i5, and its clock speed is 1600 MHz while idle but it rises automatically to 3600 MHz when loaded.

Use vim sometimes for "massive editing". Really love keyboard macros and commands like 10000@a (it's like "Do everything good" button).

Hi all!

Does anyone know how to kill X server in guest system (VirtualBox) without interfering with the host OS? Ctrl+Alt+Backspace just kills host X server which I don't want to do.

Yes, it does. MS doesn't distribute their kernels as separate products but kernel as architecture element is present in all OSes, of course.

Moreover, I think it's possible to use one /home partition for sevral...

2. If a file cannot be read, it cannot be copied,...
