I upgraded to a 500GB hard-drive and installed windows 7 on it. I then moved my current ubuntu installation from the older HDD to the newer one on another partition, but of course there was no bootloader to load it. I had GRUB2 on older hard drive. I googled about how to recover GRUB2 but couldn’t find one. All I could find was solutions to fix corrupt Grub. So, I just reinstalled grub and then upgraded it to Grub2.
Here’s how to do it:
Boot into Ubuntu Live CD.
Mount the root disk (Disk on which Ubuntu is installed).
mkdir /media/root
mount /dev/sda7 /media/root
where /dev/sda7 is your disk.

I was excited for the Karmic Koala (v. 9.10) which came out yesterday and I happily started the download and kept the computer switched on overnight for the download to complete. When I woke up, surely the download was completed and I went on to install the downloaded packages. Which the installation was taking place, power went off and computer switched off abruptly. I was in shock and feared I wouldn’t be able to boot into Ubuntu again.
My fears came true when booting process stopped at “waiting for /dev/sda6″. I waited for quite a while but it would never proceed to next step. I pressed Esc and I was dropped into root terminal. I at once did
dpkg –configure -a
That didn’t help much. It gave me error “Read-only file system”. So, I made the file-system writable by doing

Today I experienced a rather strange problem in Ubuntu. It crashed. Actually it wasn’t completely crashed, the mouse clicks weren’t working, I couldn’t switch using Alt+Tab, I could only use the program which was on the screen. The panels weren’t working, though the shortcut keys were. Fortunately enough, I had assigned shortcut key to open the terminal and it was working, so I could even access the terminal.
Fortunately, firefox (shiretoko) was running as the frontmost application and I was able to access the internet. I searched for How to kill X and was presented with many solutions.
I tried killall X in terminal but it didn’t work. Suddenly, I remembered that X was called Xorg in jaunty. I did this:

My laptop has a synaptic touchpad and its horizontal scroll was not working ever since I moved to Ubuntu. I didn’t pay attention to it in the beginning as it was not much of a use. But later on it started bugging me so I finally decided to resolve this problem.
Well, installing gsynaptics and enabling the horizontal scroll didn’t work for me but that may work for you. So try this:
In terminal, type:
sudo get-apt install gsynaptics
Type in your password and let it install the package. After installation, go to System->Preferences->Touchpad.

Well all OSes have bad programs, Linux has it too. Some times they stop responding and unlike windows, they don’t make the whole OS unresponsive. The application alone is unresponsive but you can still use other applications normally. Killing an unresponsive application is fairly easy job in Ubuntu.
Bring the unresponsive application to the front, the app must be having a desaturated look because its unresponsive (if its not, check again… it must not be unresponsive). Launch the terminal and type:
$ xkill
The mouse cursor will change to a cross, click anywhere on the unresponsive application and it will be killed.
To get things done faster, you can type xkill in “Run application” dialog box too. Press Alt+F2 to bring the run dialog box and type xkill and enter. The mouse cursor will change to cross and click on unresponsive app to kill it.

I had many wmv files but I wasn’t able to play them.
Ubuntu by default doesn’t support wmv files due to legal reasons. You can, however, make them play.
In terminal, type:
sudo apt-get install ubuntu-restricted-extras
Or, you can go to synaptic package manager and install ubuntu-restricted-extras.
After installation, you will be able to play wmv files.
Cheers!
). Fortunately, I found two packages in repos which could work similar and better than guitar pro. Best of all, they are free.
