A quote from wiki.ubuntu.com: " The GIMP has been removed from the default installation in order to make room for more features and content to be included in Ubuntu. Basic functionality for image editing provided by The GIMP can be found in some of Ubuntu's other applications, such as F-Spot. The GIMP remains available in the package repository. " In the next version of the well known Linux distribution Ubuntu (10.04 - Lucid Lynx) the Ubuntu developers decided to adjust the default applications. GIMP will be classified as software for specialists which means that GIMP will not be installed by default any longer. This is how you can install GIMP from command line. Open up the terminal and type: $ sudo apt-get install gimp

I recently installed Windows 7 on my laptop which already had ubuntu remix installed in it. The problem i faced was, the GRUB was lost. But i had trouble getting your GRUB boot loader since the process of restoring GRUB has changed. Follow these instructions to restore your GRUB. 1. Boot from your UBUNTU LIVE from which you installed Ubuntu 2. Now open up the terminal. 3. Now find out the drive in which you installed Ubuntu. print the "Partition table" and find out the drive. $ sudo fdisk -l 4. Now mount the drive. $ sudo mount /dev/sd D P /mnt ' D ' is the drive number and ' P ' is the partition number. In my case, It was 'sudo mount /dev/sda3 /mnt' 5. Now install GRUB. $ sudo grub-install --root-directory=/mnt /dev/sd D ' D ' is your drive. For me it was 'sda'. 6. Now unmount the drive and reboot. $ sudo umount /mnt You should have your GRUB restored by now.

I recently installed the new Ubuntu Remix 9.10 karmic Koala on my laptop. I found that all windows where automatically maximized when open. I had showed you how to disable the auto-maximize feature of ubuntu remix earlier. Another annoying feature was that the maximized windows doesn't have the restore/maximize, minimize and close buttons on it. If you need it just enable it as i have said below: Press Alt + F2 , enter gconf-editor , Go to -> /apps/maximus/undecorate and unset it. (i.e uncheck the check-box). Thats it.

I recently installed the Ubuntu Remix on my netbook. The most annoying feature i found was the 'Maximus'. It maximizes every window you open, even small windows which should not be maximized. This is how you can disable this feature. Press Alt + F2 , enter gconf-editor , Go to -> /apps/maximus/no_maximize and set it to " true " (i.e check the check-box). So, if you want the restore, close buttons on the maximized windows then uncheck 'undecorate' .
