| − | Slackware 13.37 64-bit installed like a breeze on a hot, humid day! For the most part all of the essentials to get the system up and running on the W520 was detected and put into play with little or no intervention or editing of files on my end. Kernel 2.6.37.6 was supplied with Slackware 13.37 so I compiled and installed 2.6.39.2 using the .config file from the testing/source/linux-2.6.39-rc4-configs/ directory on the Slackware install DVD. Made some minor changes to the config as follows:

| − | Coming from a W510, the W520 introduced me to the concepts of discrete and integrated graphics, as well as NVIDIA's Optimus technology. Unfortunately because of NVIDIA's unwillingness to bring Optimus support to Linux, you have three choices. You can use the integrated Intel HD graphics, NVIDIA's discrete graphics, or look into the bumblebee project [https://github.com/MrMEEE/bumblebee#readme here]. I went with the NVIDIA discrete graphics route with plans to try out the bumblebee project at a later time. Make sure to specifically set your graphics option in the BIOS to discrete, otherwise Slackware/Linux will select integrated.

| − | Instead of the open source nouveau driver, which is limited to 2D graphics I went with NVIDIA's binary, version 275.09.07. Used xf86-video-nouveau-blacklist-noarch-1.txz in the extra/ directory on the Slackware install DVD to blacklist the loading of the nouveau driver, which causes conflicts with NVIDIA's binary. With X.Org's X Server 1.9.5 in Slackware, xorg.conf is pretty bare these days as detection is done pretty smoothly at start. Using NVIDIA's installer to create a default xorg.conf, the only things I edited were

| − | The [[Intel Centrino Ultimate-N 6300]] Wi-Fi card and [[Intel Gigabit Ethernet (10/100/1000) PCI-Express]] Ethernet card both worked right out of the box.

| − | * While Turbo Boost IS working properly with recent distros, built in Linux utilities do not currently show Turbo Boost activity. Intel Powertop or i7z will show actual CPU state properly, including Turbo Boost and advanced C-states. Can be verified running Ubuntu Lucid and compiling a kernel or other tasks, WHILE ON AC POWER.

| − | * If you find the flashing wireless LED annoying, you can change its behavior so it will be on steady whenever the radio is powered on, and off when the radio is off. Add "options iwlcore led_mode=1" to /etc/modprobe.d/iwlcore.conf to set the LED on steady, or you can set led_mode=0 to have it flash whenever there is wireless activity (default)
