ubuntu

I recently upgraded my ThinkPad to 4GB RAM. However to my surprise I learnt that 32-bit OSes can only access 3GB of the RAM. Sad, isn't it? But, here's how to get happy -

I recently installed Kubuntu 10.04 LTS and loved the fast boot time, but there was this NVIDIA proprietary driver not working properly. I was not able to use all possible resolutions and the picture was buggy. After some time Googling, I just tried to launch the NVIDIA settings which suggested to run nvidia-xconfig to update the X configuration. I did it and it worked perfectly!

Hope this helps

I regularly connect to my father's Ubuntu PC using ssh to help or to transfer files through scp. I have been using ssh keys to make these logins password-less and I thought the method needs a blog post :)
Generally a user can have two keys - a private key and a public key which we generate using the following process and then copy the public key to the remote machine. Remember, don't give anyone your private key.
