Posted by on January 30, 2012 No comments

This happens only if you have more than 4 cores.

Here is how to fix it:

install dconf-tools with the ‘sudo apt-get install dconf-tools’ command
start dconf-editor
navigate to org->gnome->gnome-system-monitor
modify the cpu-colors key’s value two more tuples in form of (core_number, ‘#FFFFFF’).

For my 8Core machine it looks like this:
[(0, '#FF6E00'), (1, '#CB0C29'), (2, '#49A835'), (3, '#2D7DB3'), (4, '#FF6E00'), (5, '#CB0C29'), (6, '#49A835'), (7, '#2D7DB3')]

Hide the facebook Sidebar / Chatbar

I prefer using the older Facebook UI. It’s cleaner to me and doesn’t OD on Information. The new one kind of goes insane with the number of updates.

I wrote a chrome extension to hide these and go back to my sweet old Facebook interface :)
