This article exists to provide detailed instruction on how to install and configure Gentoo Linux for the Toshiba Satellite A105-S4094 Laptop. Much of this article is derived from this article on the Toshiba Satellite M105 Series. Much thanks goes to its respective author(s).

This article assumes that you are not a first time Gentoo user, that is, this isn't your first install, hence you are not a 'newb'.


To be honest, I've been toying with Gentoo Linux on a desktop for several years, but I've never even compiled Gentoo on an INTEL platform...don't laugh. Some of the stuff is the same, but some of it's very different. In short, this article will really help those of you coming from a desktop world like myself, and help configure everything that can be configured.

Hardware / Specs

To be filled in later

Initial Installation

For basic installation instructions, please refer to the Gentoo Installation Handbook. The text that follows is only supplimental, not step-by-step.

Initial Setup

Depending on what install method you use/prefer, the network (ethernet) card may be detected but not activated. Since I prefer command line installs (minimal install cd), running net-setup eth0 quickly fixed my ethernet connection to active. By the way, for documentation's sake, the driver for the ethernet card is e100

Disk partitioning

Your partitioning will vary upon your needs. Just keep in mind that the included hard disk is SATA, you will access it via /dev/sda. Also keep that in mind when compiling your kernel.

/etc/make.conf configurations

Again, your USE variables will depend upon your needs as will specific CFLAGS. That said, what you should know is that for your CFLAG entry, your processor type is prescott. Also, there are some very important USE flags you may want to include, as well as specific flags for modular Xorg configuration. Included is my basic /etc/make.conf from which you can adapt to your needs.

File: /etc/make.conf
CFLAGS="-O3 -march=prescott -pipe -fomit-frame-pointer"

########## USE and UNUSED #######################
USE="   -arts -ipv6 -apm

        dvd real win32codecs firefox wmf cddb acpi avi "
INPUT_DEVICES="evdev keyboard mouse synaptics"
VIDEO_CARDS="i810 i915 i940 intel vesa"


At this point, now that all appropriate /etc/make.conf entries have been taken care of, we can move on to our first emerge --sync

Sync n Stuff

Nothing special really goes on here, but whilst some of the documentation defers you from doing a emerge --update --deep system -va I prefer to do one right after the sync. Go for it, and grab a beer. This whole process will take about an hour or so...chances are you'll have to update GCC and glibc.

Kernel Internals

Now onto the difficult part, including all the right stuff into the kernel. Grab your specific kernel flavor (gentoo-sources for me) and get on to making that menuconfig. Hopefully you have configured and compiled a kernel before, because this isn't the place to learn how. Heres what to make sure you have included in your kernel (2.6.17-gentoo-r4)

That should be just about everything to get you started. Go ahead and make and copy over to /boot as necessary.

Finishing the install

The last thing you will want to do is install all of your specific programs to your laptop. Not necessarily the x server and gnome, but things like slocate, dhcpcd, cron, coldplug....etc. So go for it. Don't forget about a boot loader. Now reboot, and lets make sure everything came up fine...kernel wise.

Post-Installation Configuration

Configuring Xorg for your laptop, and screen resolution

Once we have xorg-x11 installed, we can start configuring it. As a window manager, I prefer [fluxbox], its a fast easy install, and it's great for initial testing. Anyways, for configurations sake, follow the initial instructions located [ here]. Specifically, run Xorg -configure which will give us a basic xorg.conf file that we will edit for our own interests. Said command will leave us with an file in our working directory. We can test our configuration changes with X -config /root/ But like I said, refer to the X setup guide for details.

Without any editing, we should have a basic working config file that should get xorg up and running. We can go ahead and copy our test conf file over to /etc/X11/xorg.conf. Our next task, as you may have noticed is to setup our proper screen resolution (1280x800).

Since there is no native support for vesa mode 1280x800, we need to add a mode line to our Monitor section of of /etc/X11/xorg.conf. Detailed instructions of how to do so can be found at Widescreen wiki.

Included here is my basic /etc/X11/xorg.conf which should get you going, in case your stuck or need some guidance.
