SteamOS on Lenovo T510 with Nvidia Optimus

SteamOS is still in beta but releases come out and I found the concept interesting.  However, you need a PC with UEFI BIOS and a newer Nvidia or ATI card (although I think an Intel may work).  SteamOS is basically meant to run a Home Theater PC in your livingroom and/or be a gaming console with a controller (Xbox controller can work here if you have the right model/driver).  I was more curious than anything but it wasn’t easy to get this running on the T510.  This is just to share what it took and to bookmark a place for me to come back to (since I have other purposes for this computer, namely openstack testing with Mirantis).

The Lenovo T510 I used has an Nvidia NVS 3100T card and the i5 processor.  Lenovo, and many other manufacturers, did not add UEFI until 2012 (meaning that it is in the T520 but not the T510).  Furthermore, the Nvidia Linux driver dropped support for many older cards (like the 3100T) after the 340.x driver version (I think it’s on 343 right now?)  Steam builds the driver in their Debian-based installer and if dmesg shows NVIDIA, it will assume you want the new drivier.  The issue is, automation breaks because it will prompt about an unsupported driver, so the automated install always will fail.  In any case, here’s how you do this.

WARNING: This wipes out all data on the drive!!!

  1. Get the ISO version of the install, you can do this yourself or get a precompiled copy.  It’s just easier to make a DVD here (because USB boot is based on UEFI and you have to fake the CDROM being the USB…trust me, just burn a DVD for this).
    1. Get the ISO by going the the steam forum and checking for a new sticky on a release and burn a DVD – http://steamcommunity.com/groups/steamuniverse/discussions/1/
  2. Boot up the laptop with DVD and let it install (you can select expert).  Midway through the core install it will error and have a message about trying it 5 times again, You need to just click back until it gives you an option for continue, putting you back on a menu screen.  At this point we jump to tty2 by pressing CTRL-ALT-F2 and perform the following commands:
    1. chroot /target /bin/bash
    2. apt-get install -f
      1. If you get the nvidia installer ignore the next step
    3. apt-get install nvidia-*
      1. When the installer asks to install an unsupported card, say yes, you’ll get two more installers ask questions, select the obvious choices
  3. Hit CTRL-ALT-F5 (I think) to go back to the installer and select install core components (or the selection it should already be on). It will warn of a dirty install, say it’s ok and wait. It should complete the installation (maybe give a warning but it’s fine)
  4. It should boot into a gnome desktop where you need to enable the network, it will update steam and reboot.
  5. It will boot to the GRUB menu and should backup the system partition (select this if it doesn’t do it automatically). upon the next reboot, hit ESC after the lenovo screen (be quick) to get the GRUB menu to show.  Select the (recovery mode option) and it should boot to command line.
  6. At boot, login with desktop/desktop and we will be following most of this guide. but we need to have network enabled first and this is not up on recovery (at least correctly).
    1. login if you’re not already with desktop/desktop
      1.  you may need to set the password using the “passwd” command after login (make it: desktop)
      2. change the Xorg to GDM3 by running the following
        1. sudo dpkg-reconfigure lightdm
          1. select gdm3
        2. sudo passwd steam
          1. set it to “steam”
        3. sudo reboot
    2. Hit ESC after the Lenovo splash screen, keep trying until you see a legacy graphic backsplash of SteamOS and the Grub menu should appear after a few seconds
      1. Select the normal boot option this time and let it boot into the gnome desktop
      2. once you’re in (you may have to select STEAMOS for login), hit CTL-ALT-F2 for the command line
      3. Logon with desktop/desktop and proceed to step C
    3. install compilers for headers
      1. sudo apt-get install build-essential linux-headers-$(uname -r)
      2. wget http://us.download.nvidia.com/XFree86/Linux-x86_64/340.76/NVIDIA-Linux-x86_64-340.76.run
      3. sudo chmod +x NVIDIA-Linux-x86_64-340.76.run
      4. sudo apt-get –purge remove xserver-xorg-video-nouveau nvidia-kernel-common nvidia-kernel-dkms nvidia-glx nvidia-smi
      5. sudo apt-get remove –purge nvidia-*
      6. sudo nano /etc/modprobe.d/disable-nouveau.conf
        1. # Disable nouveau
          blacklist nouveau
          options nouveau modeset=0
        2. add the lines above and save this new file (CTRL-X then Y then ENTER)
      7. sudo dpkg-reconfigure lightdm
        1. select lightdm
      8. sudo reboot
    4. Hit ESC after the Lenovo splash screen (we’re going back to recovery) and select the recovery option in Grub (should be on bash already)
      1. cd /home/desktop (I think, might be steamos)
      2. ls -la (see if the NVIDIA file is there, if not, find it)
      3. sudo /etc/init.d/lightdm stop
      4. sudo /etc/init.d/gdm3 stop
      5. sudo ./NVIDIA-Linux-x86_64-340.76.run
        1. ACCEPT EULA, say YES to DKMS, YES to 32bit compat, YES to Xorg config and click OK
      6. sudo reboot
    5. Boot to normal mode and wait (you may have a big cursor and be waiting for over 10 minutes).  I had dinner, came back and I was up and running

Hope this works for some of you who want to test it!

This problem has been raised so hopefully it will be addressed in the final release

PS – I noticed a few other interesting places discussing this which I haven’t tried

1) http://steamcommunity.com/groups/steamuniverse/discussions/1/648814395823405268/

2) GitHub for non-UEFI boot (no legacy nvidia yet) – https://github.com/directhex/steamos-installer
