multi session with Medit

Create three launchers, each for different purpose/session



Command examples:

medit -n --use-session=yes --app-name=notes_txt

medit -n --use-session=yes --app-name=source_c

medit -n --use-session=yes --app-name=web_php

Each of them will remember it's owned session (previously opened files and etc.).
Except for working directory in Pane "File Selector", bud you can make bookmarks and switch fast.

Install grub from live Linux Mint

 If You installing Windows on a HDD whare Linux already intalled.
There is not a lot of reasons for this, in general installing windows its not a good idea (my opinion)! But if You really want this! This is the way to do it!

After Windows installation is complete. Boot live Linux Mint from USB flash or from DVD-ROM... and open terminal.

If You tray something like this (this worked on Debian squeeze, and I believe it sill works):
$sudo grub-install /dev/sda

On Mint this is what you will see:
grub-probe: error: failed to get canonical path of /cow.
Path `/boot/grub' is not readable by GRUB on boot. Installation is impossible. Aborting.

To fix this, mount rootfs. You need to specifay not only device ,bud path to mounted rootfs.
Enter something like this:
$sudo grub-install --recheck --root-directory=/media/mint/ac61ecb9-7b20-4d94-b9e2-9b1ece015459/ /dev/sda

Grub-probe will still complain ... bud its not important, cause grub will be installed successfully.

Now reboot (remove live cd or flash). Now You will not see grub menu, and Linux will boot up.
So ,You need to update grub:

$sudo update-grub

Reboot again.

And now all OS available in grub menu!

If Selective self-test is pending on power-up, resume after 0 minute delay.



Or graphical tool can be used for that (in terminal "palimpsest",program title "Disk Utility",under "SMART data"):







I don't know way it says "Good"?
There is definitely nothing good about that!
It generally means - make a backup fast!

Unfortunately I unable to find applet or tool to notify about this type of errors.
I have to periodically check my self.
In the future I will fix this inconvenience!
