I am a programmer and I can’t do without a clipboard manager. If you have never used a clipboard manager before, you don’t know what a great tool you are missing. GPaste is an excellent clipboard tool for Gnome-Shell, however it is neither available in Ubuntu repository, nor in any PPA (as of now). Here is how you can compile it. Open up the terminal and get going.

I have just installed Gnome 3 in Ubuntu 11.10 Onieric Ocelot. In Gnome-Shell interface, there are no title bar controls for minimize, maximize/restore. To enable them, open up the terminal and type in (or copy/paste) the following command: Continue Reading

I have installed Ubuntu 11.10 Oneiric Ocelot on my laptop. I had been using Ubuntu 11.04 Natty Narwhal on it and since I use this PC for work, I was reluctant in installing Gnome-Shell from PPA. But since Gnome-Shell is available in official repositories, I decided to give it a go. To install, just open Ubuntu Software Center, search for Gnome-Shell and click “Install”. After installation is complete, log out and when logging back in, select Gnome (see screenshot below).

When trying to purge Gnome3 PPA, I had to cancel the ppa-purge process and when I tried to run the same, I got the following message: Continue Reading

I have installed sun-java-jre/jdk on my Ubuntu and Fedora. I am using svn for my project and have been running it well with my old Fedora 15 installation on my old PC. However, recently I installed Fedora on my other machine and installed Netbeans 7.0.1 on top of sun-java. Fedora did not handle graphics very well, so I installed Ubuntu alongside as well. But every time I tried to access subversion functionality from Netbeans, I got the following error: Continue Reading

Having video and sound issues with Fedora 15, I decided to try out Natty on my HP Pavilion G4 1009tx. Surprisingly, sound and 3D effects ran great with Intel onboard graphics so I installed it onto the Hard drive. In all excitement, I decided to try out proprietary ATI drivers for the switchable dedicated AMD Radeon HD 6470M graphics. However, when I rebooted, it would not boot. It seems that plymouth crashes and system ends up with a black screen. So, I decided to remove fglrx and keep on using Intel card but it seems that I can’t even boot into recovery mode. So, I had to remove fglrx and make the system usable again using the Live CD and chroot. Here is how I did it.

Linux Kernel 3.0 RC 1 was recently released. Although it does not have real changes to anything, but is just a renaming of 2.6.40, however, you may want to install it for testing and using it if it works good for you in your Ubuntu Natty installation. It has bug fixes and additional drivers so it may solve problems. However, it may also introduce new problems, so be careful not to remove the other kernel (2.6.38) after installing it. This tutorial also contains instructions to remove it safely, so read along. Ubuntu 11.10 Oneiric Ocelot will be released with kernel 3.0.

If you have used Unetbootin to setup a Live Ubuntu Environment, you will find that the partition containing the Unetbootin files will be mounted on /cdrom as read-only, which means, even if you launch nautilus with gksu or sudo, you will not be able to make changes to the file-system. There is however, an easy workaround which involves remounting the filesystem with a single command. Open up the terminal and type in the following: Continue Reading
