Fedora 17 on laptop?

I have a laptop which came with windows 7.
I want to install fedora 17 on this laptop.

i5, 4gb ram, 1gb graphics card.
Will all the laptop functions work after switching to linux?
Battery level, touchpad, function keys...?

Re: Fedora 17 on laptop?

Generally everything works fine.

There may be issues with some pieces of hardware. If you could post more details we may be able to tell.

The easiest thing to do is create a livecd/usb and boot the laptop from that. You can then see if everything will work without overwritting it all.

Re: Fedora 17 on laptop?

Okay. First things first, assuming you are using GNOME:

Touchpad.

1. At the top right of the screen, click on your name.
2. Click System settings.
3. Click Mouse & Touchpad
4. Click on the tab labelled Touchpad.
5. Tick the box Enable mouse clicks with touchpad. (Perhaps the scrolling options as well.)

Secondly, battery life. This is a trick one, my understanding is that the windows drivers are tuned by the companies to get maximum battery life. There are a few things you can do:
1. Install powertop (http://unix.stackexchange.com/questi...e-in-fedora-15)
2. If there are two graphics cards (like with nvidia optimus, I think the nvidia card draws a lot of power and cannot be shut off in linux.)

Re: Fedora 17 on laptop?

I do not think that powertop will help with optimus.

You can install software in a livecd mode, (unless you set it up with persistant storage) they will be removed when you restart the machine.

In power top you can scroll to the right (use the arrow keys). Then there are options to toggle. By pressing enter you can toggle from bad to good to enable powersaving measures. Not sure what they all do, I toggle all of them. I got an extra hour out of my laptop by doing this.
