Here I’m writing down all the steps I followed after installing Debian 7. I’ve already installed Ubuntu Server 12 and build up from there. Everything works fine using ubuntu. However, lets try Debian 7!

Debian version:

$ lsb_release -a
Distributor ID:	Debian
Description:	Debian GNU/Linux 7.2 (wheezy)
Release:	7.2
Codename:	wheezy

First, after installing Debian, I can feel the heat coming out the CPU. Although it was the same with Windows 7, you can change power settings to lower the fan speed… and stop the noise.

Update kernel

$ uname -a
Linux dell-xps-l502x 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux

There is a problem with the 9-in1 card reader. To enable insert the card and run:

# echo 1 > /sys/bus/pci/rescan

The kernel version 3.12-rc2 resolve the card reader problem. Bug status: Currently this is an experimental version. To install it follow the steps here:

I prefer wait and install the backport version.

Enable backports to update the kernel. Add repository to /etc/apt/sources.list.

# backports
deb wheezy-backports main

Install and restart the laptop.

# apt-get -t wheezy-backports install linux-image-3.10-0.bpo.3-amd64

Check kernel version.

$ uname -a
Linux UNKNOWN 3.10-0.bpo.3-amd64 #1 SMP Debian 3.10.11-1~bpo70+1 (2013-09-24) x86_64 GNU/Linux

It works! Restart the laptop. Performance has been improved. You can notice how boot time improves.
