====== Lenovo Thinkpad X60s ======

**This place serves as documentation for my Lenovo Thinkpad X60s Setup under Linux.**

I have a X60s 1704-69U (aka 170469U).
I'm using Gentoo (currently 2006.0)

Until organized, it'll just be a wild collection of bits and pieces.

==== Kernel Configs ====
  * 2.6.19.1 with atheros/madwifi: {{:config-2.6.19.1-madwifi.txt|:config-2.6.19.1-madwifi.txt}}
  * 2.6.19.1 with intel3945abg: {{:config-2.6.19.1-3945.txt|:config-2.6.19.1-3945.txt}}
    * yes, I recently exchanged my atheros wifi card with a intel 3945abg

==== CPU ====
  * Processor L2400 @ 1.66GHz
    * SMP
    * CPU frequency scaling (1000MHz, 1333MHz, 1666MHz)

==== Ethernet ====
    * eth0 (Intel e1000)

I seem to have a problem with latency with the e1000. SSH connections even to machines
directly on the same switch have a very noticeable lag from typing to displaying.

  00:1f.2 SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) Serial ATA Storage Controller AHCI (rev 02)

=== Harddisk ===
The Harddisk is connected to the SATA bus.

My harddisk showed a frequent "clicking". One of the ways (probably not the best) to get rid of this is to disable Power Management on the drive:
<code>
# hdparm -B 255 /dev/sda

/dev/sda:
 setting Advanced Power Management level to disabled
</code>


=== CD / DVD Drive ===

The CD-R/RW / DVD-R/+R/-RW/+RW/-RAM optical drive (aka. Multi-Burner) in the X6 Ultrabase Docking Station is connected to the regular IDE controller, and appears as /dev/hda

The Harddisk is connected to the SATA bus.

==== X11 ====
The X60s has a Intel 855GM Graphics controller. 
''lspci'' says:
  00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)
  00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)

I've built Xorg with i810, vesa, fbdev and vga drivers enabled.
I use i810 as xorg driver.
    * I had to use xorg from ~x86, these are the packages:
      * xorg-x11-7.1
      * xorg-server-1.1.1
      * xf86-video-i810-1.6.1
DRI now works (but maybe not 100%). I had to disable drm in the kernel completetly. Then I rebuilt x11-drm (version 20060608). There were still problems because the drm.ko module wasn't copied to /lib/modules/`uname -r`/x11-drm along with the others (eg. i810.ko, i915.ko). To quickly fix it, I re-emerged x11-drm, froze the build process with Ctrl-s after drm.ko was done building, and copied that module to its proper place, then I let the build process resume with Ctrl-q.
    * for DRI to work, **both** agpgart and intel-agp have to be loaded.

fingerprint reader, bluetooth, wwan modem are USB-based, so they are only visible if usb-uhci is loaded. ''lsusb'' shows devices on the USB bus:

^Kernel Modules: | sdhci mmc_core mmc_block |
^Programs: | |

Starting with recent kernels of the 2.6.17 series, sdhci is included in the official kernel. Older kernels need to be patched.

If the above modules are loaded, this should suffice to mount the card:
<code>mount /dev/mmcblk0p1 /mnt/mmc</code>

I tried it with a cheapo 128MB MMC card.

<code>
  * We don't have a patch for kernel 2.6.18 yet
</code>

Apparently, one of the above three modules probits the resume from suspend-to-ram.

==== Power Management ====

=== Suspend-to-RAM ===
    * until I set CONFIG_HOTPLUG_CPU, it didn't even succeed to suspend. After this was set, suspending worked, but resuming needed some more work (see the following)
    * you need to give the kernel the following parameter: acpi_sleep=s3_bios,s3_mode
    * needs at least 2.6.18-rc1 together with some patches:
      * http://www.andrew.cmu.edu/user/gnychis/ahci-patch1
      * http://www.andrew.cmu.edu/user/gnychis/ahci-patch2
      * http://www.andrew.cmu.edu/user/gnychis/ahci-patch3
      * http://www.andrew.cmu.edu/user/gnychis/ahci-patch4
      * http://www.andrew.cmu.edu/user/gnychis/ahci-patch5
      * http://www.andrew.cmu.edu/user/gnychis/ahci-patch6
    * (this information is based on what I found here: http://farmerzonen.dk/x60s#comment-497 )
    * I tried 2.6.17 (gentoo-sources-2.6.17-r4) but after the resume the SATA controller didn't work right (problems with ahci). From a few things I read, it might be possible to get it to work with 2.6.17, but only if the SATA controller is put in something like "compatibility mode" (as opposed to AHCI mode) in the BIOS. I haven't checked this.
