У меня была похожая проблема...
Люди подсказали:
-----------------------------
# apt-get install os-prober
# os-prober
# update-grub2
-----------------------------
Первая строчка- доустановка модуля поиска "других" OS.
Вторая- запуск модуля- поиск "осей".
Третья- внесение изменений в меню GRUB'a.
Q: Вобщем как можно вывести в консоль количество пакетов которые подлежат обновлению после apt-get update ???
Облазил все поисковики... ничего похожего не нашёл... :( Да и у самого идей нет как такое осуществить :( но очень надо :(
A:
Сам недавно столкнулся с точно такой же ситуацией, только наоборот -
дома трафик дорогой, а на работе unlim. ;) Погуглив, где-то на
ubuntuforums (к сожалению, не помню уже где), наткнулся на простое и
изящное (ИМХО) решение :
#!/bin/bash
apt-get upgrade -y --print-uris | cut -d"'" -s -f2 > ~/upgrade_package_names.txt
После чего получаю в домашнем каталоге файлик с URL`ами upgrade_package_names.txt

GiftWrap
is a hassle-free way to create Ubuntu packages. It is designed for
anyone who deals with distributing software - be it theme artists,
software developers, or anyone else.It stems from the (now dead) Deb Creator project.In the future, it will support updating of existing packages, uploading to PPA's split packages and more.
Installation :
Open your sources.list and add GiftWrap's Official Launchpad repository :$sudo gedit /etc/apt/sources.list
For Ubuntu Jaunty Users :deb http://ppa.launchpad.net/giftwrap/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/giftwrap/ppa/ubuntu jaunty main
For Ubuntu Intrepid Users :deb http://ppa.launchpad.net/giftwrap/ppa/ubuntu intrepid main
deb-src http://ppa.launchpad.net/giftwrap/ppa/ubuntu intrepid main
Save and exit.Now import the public key with this command and update the system :$sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 207CAD03$sudo apt-get update
Now install GiftWrap :$sudo apt-get install giftwrap
After
installation done (you may be asked for some configurations like mail
server etc.If you do not know what you are doing, just select "No
Configuration" ), you can run GiftWrap via Applications >
Programming > GiftWrap OR giftwrap command and start building your
own Ubuntu packages ;)

Today i destroyed my Grub2 via installing windows on my notebook which
i write blog posts.(I quit smoking , so i have to play some games : )
No rush). It may be hard to recover it since there are not much (i did
not find anything) howtos around the net about recovering Grub2.Here is
the step by step guide to recover it :
You will need a LIVE cd
if you are going to recover an Ubuntu Box.Download Ubuntu Jaunty,
Karmic whatever you want.Open the system with Live CD (I assume you are
using Ubuntu Live CD).Press Alt+F2 and enter gnome-terminal command.And
continue by entering :
$sudo fdisk -l
This will show your partition table.Here is my table to understand it better :
/dev/sda1 29 8369 66999082+ 83 Linux
/dev/sda2 * 8370 13995 45190845 7 HPFS/NTFS
/dev/sda3 13996 14593 4803435 5 Extended
/dev/sda5 13996 14593 4803403+ 82 Linux swap / Solaris
Now
i will mount Linux (sda1 here), i have no external boot partition as
you can see.(IF YOU HAVE external one, do not forget to mount it! )$sudo mount /dev/sda1 /mnt$sudo mount --bind /dev /mnt/dev$sudo mount --bind /proc /mnt/proc
The following command is optional (it copies resolv.conf)$sudo cp /etc/resolv.conf /mnt/etc/resolv.conf
Now chroot into the enviroment we made :sudo chroot /mnt
After chrooting, you do not need to add sudo before your commands because from now, you will run commands as root.
You may want to edit /etc/default/grub file to fit your system (timeout options etc)#nano -w /etc/default/grub
Play with the options if you want.(But do not forget to give grub-update command if you saved it ;) )
Now install/recover Grub2 via :#grub-install /dev/sda
command.However you may get errors with that code like me.If so please use this command :#grub-install --recheck /dev/sda
Now you can exit the chroot, umount the system and reboot your box :#exit$sudo umount /mnt/dev$sudo umount /mnt/proc$sudo umount /mnt$sudo reboot

A few months ago I was telling you about sK1,
an open source vector graphics editor similar to CorelDRAW, Adobe
Illustrator, or Freehand. At the time, you had to compile it, but now
(actually it exists for quite some time, but I wasn't aware of it)
there is an Ubuntu repository from where you can install the latest
version.
Why sK1 and not InkScape?
While InkScape is oriented to the SVG format and is ideal for web design, sK1 targets professional designers from the prepress world. So sK1 supports CMYK, multiple pages and separating colour plates.
Open a terminal and paste the following command to add the PPA repository:
-For Ubuntu Jaunty (9.04):
sudo sh -c "echo 'deb http://ppa.launchpad.net/stani/ppa/ubuntu jaunty main' >> /etc/apt/sources.list"
-For Ubuntu Intrepid (8.10):
sudo sh -c "echo 'deb http://ppa.launchpad.net/stani/ppa/ubuntu intrepid main' >> /etc/apt/sources.list"
Then, add the GPG key:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 7B0FB2CA
And finally, install sK1 in Ubuntu Linux:
sudo apt-get update && sudo apt-get install sk1
Download sK1 .deb for Ubuntu 9.04 (Jaunty) without adding the PPA repo
Additionally,
you can just download the Ubuntu .deb if you want. But before
installing it, you need to firstly install some dependencies, so open a
terminal and paste this:
sudo apt-get install tcl8.5 tk8.5 python-imaging python-imaging-tk python-liblcms python-reportlab
Then you can download and install sK1 .deb: Ubuntu 32 bit | Ubuntu 64bit
A note from the PPA maintainer:
this is the development version of sK1 and the packages have not been
tested by a critical mass. In case you have problems, you should report
them on the sK1 forums.
The packaging is not perfect yet. For example there will be no entry in
the start menu. This will be fixed in a next release. I've sent Igor
from sK1 the necessary files to resolve this issue. So for now start
sK1 by typing "sk1" in the run dialog (Alt+F2) or in a terminal.
As a final remark: you need to remove your ~/.sk1 folder, otherwise sK1 might have troubles starting up.
[thanks to Stiani for maintaining the PPA]
This quick tip is for Gnome users. I always wanted new windows to start
centered on the desktop but never searched for something to modify this
behavior. But yesterday I stumbled onto something which fixes this by changing 2 parameters in Gnome's almighty gconf editor:
Press Alt+F2 and enter gconf-editor, then set the following two values:
Key: /apps/metacity/general/focus_new_windows Value: smart
Key: /apps/compiz/plugins/place/screen0/options/mode Value: 1
Now your applications should start up nice and centered.

The
complete database is always encrypted either with AES (alias Rijndael)
or Twofish encryption algorithm using a 256 bit key. Therefore the
saved information can be considered as quite safe. KeePassX uses a
database format that is compatible with KeePass Password Safe. This
makes the use of that application even more favourable.
The menu and button icons are disabled by default in Gnome 2.28, like I was telling you some time ago. Basically, this is how the menus and buttons look like in Gnome 2.28.
But this can be changed. For the menu part, it's very easy: just go to System > Preferences > Appearance and under the Interface tab, check the "Show icons in menus" box.
Now, for the buttons, run the following commands in a terminal:
gconftool-2 --set /desktop/gnome/interface/buttons_have_icons --type bool true
gconftool-2 --set /desktop/gnome/interface/menus_have_icons --type bool true
This is how the menus and buttons will now

Несмотря на то, что у меня видеокарта NVidia Geforce 8500GT, я не
стал пользоваться TwinView, поскольку она дает меньше рычагов для
управления мониторами. Поэтому в статье рассматривается более
традиционный метод.

Итак, пусть имеется одна видеокарта с DVI и D-SUB выходами. Пусть так же имеется два монитора.
Вопрос: Как эти мониторы присоединить к видеокарте и использовать одновременно?
