power save option in Browser

Just like any embedded device going off-line, will the browser too goes offline, if there is no user action for say for 15 minutes.

This will automatically save power for number of switches / router in between the machine and Webserver as well saving power at both Machine and Webserver too...

Currently any website works based on TCP based and hence there is continuous exchange of packets between website and Webserver.If there is no user action then the browser can go completely offline so that no packet will get exchanged.

Note: there must be provision such that the connection when restored should be able to resume without any issues.

This should not be applicable when downloads are started from a Web Browser.

Intel(R) HD Graphics in Fedora 13

I have faced issues with Intel HD graphics adapter detection in lenova laptop.

Basically the adapter was not detected properly and it was showing "Unknown monitor" display in fedora 13.

I was able to fix this, by the following steps.

1. Remove the word nomodeset in grub.conf present in /etc directory.

2. move the file xorg.conf present in /etc/X11/ to xorg.conf.backup (basically xorg.conf should no longer be used).

just restart the machine. Now you should be able to change the resolution and the adapter will be detected properly.

You need this only if you face any issues while starting GUI.
If in case you face any issues with X (GUI)starting properly, restart the machine manually and boot in "single user mode" just undo the above mentioned steps.
