highres=off nohz=off irqpoll
So now your kernel line should look something like this
kernel /boot/vmlinuz-188.8.131.52-generic root=UID=a7e7a1el-97df-4718-be2b-2cbe5e4ad1e8 ro quiet splash xforcevesa highres=off nohz=off irqpoll
Now you should have a laptop that wont freeze up when enabling advanced graphic effects.

Using public and private keys ssh authorization and text expander I have my login down to as few as four keystrokes. The best part of this is that after creating all of my authorized_keys I can put them on my iPhone and then ssh in from anywhere without having to lookup my passwords.In this post I will cover the creation of the authorized public_private keys and sending it to the server with one command line.
For this to work correctly you will have to enable SSH on the computer you are sending from and unblock or map your ssh port in your firewall and or router.On your local computer create a strong dsa public private key pair using the shell command below.
local-computer$ ssh-keygen -t dsa(Do not enter a pass phrase, just hit enter)
Now lets transfer the id_dsa.pub key to your user dir on the host machinessh yourusername@server_to_connect_to "echo `ssh your-computer.local cat .ssh/id_dsa.pub` >> .ssh/authorized_keys"
Obviously you want to replace yourusername@server_to_connect_to with your login@the ip address or domain name of the server you are connecting to.For this login you will need to enter your passwords, first of the local computer and then of the server you are connecting too.
After this step you can try to connect using ssh email@example.com and see if you can can log in without a password.If you cant log in without a password check the server logs, if you see an error like this
Authentication refused: bad ownership or modes for directoryIf you do you will need to change permissions on the server by issuing the following commands on the server.
server$ chmod go-w ~/
server$ chmod 700 ~/.ssh
Now try to connect again using ssh firstname.lastname@example.org.Success!! Now issue the command again on each of the servers that you need to ssh into and you are good to go.
In part 2 We will cover using text expander on the Mac or auto-key on linux to shorten your logins down to a few keystrokes.In part 3 We will cover using this method from your iPhone.

It has some nice features like WYSIWYG Source View toggle, Previews, Categories and trackbacks, but It's more of a dedicated I'm going to sit down and write a blog post kind of application. I want something that I can just quickly write down a thought on something I'm working on or viewing in my browser and send it off as a post. Maybe I will give ScriptFire and Flock a spin.
