[SOLVED] Netbeans svn error “Duplicate extensions not allowed, OPTIONS request failed on ‘path'”

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 [SOLVED] Netbeans svn error “Duplicate extensions not allowed, OPTIONS request failed on ‘path’”

[SOLVED] Blank dark screen after installing ATI Proprietary Drivers (fglrx) in Ubuntu 11.04 Natty Narwhal

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.

[HOWTO] Install Linux Kernel 3.0 in Ubuntu 11.04 Natty Narwhal

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.

[HOWTO] Setup a Live Testing Environment for Ubuntu Daily Builds right from the Harddisk

If you are keen about the changes in the next version of Ubuntu, 11.04 (Natty Narwhal), and want first hand experience, you can setup your own live testing environment which boots right from the harddisk. You can of course test the ISOs in Virtualbox, but if your card is not supported for Virtualbox 3D, you won’t be able to test the new Ubuntu Unity interface.

[HOWTO] Enable Alt+F2 in Ubuntu Natty 11.04 Narwhal Alpha 1

If you have installed Ubuntu Natty Narwhal Alpha 1, you will notice the new Unity interface and hence no Gnome Panel(s) anymore. Since “Run Application” dialog is a part of gnome-panel, it is not possible to enable the same “Run Application” dialog. If you wish, you can achieve that by running the gnome-panel, but this is not the recommended course of action if you wish to keep running unity.
So, the other way to make it work is to use third party run dialogs from repositories. One of the best run dialog is gmrun. It is available in Ubuntu universe repositories. Open up the terminal (by pressing Ctrl+Alt+T) and type in the following to launch Synaptic Package Manager: Continue reading [HOWTO] Enable Alt+F2 in Ubuntu Natty 11.04 Narwhal Alpha 1
