The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!

works fine with Linux, some ACPI issues with Windows needs to be fixed.

Lenovo ThinkPad X60

Except where noted all status items apply to:

  • x60
  • x60s
  • x60 tablet

Aside from pre-sales configuration (display, processor speed, optional components) the three models appear identical. It is believed that they share a single schematic.

Installation and Flashing

Digitizer (X60 Tablet) and IR ports


proprietary components status

  • CPU Microcode (optional?) - works fine without. See
  • VGA option rom (optional): without it you will get no graphics during early boot, old kernel versions(like the one in trisquel 6) are able to initializes the intel graphic card. Note that the replacement doesn't work yet with seabios but works with grub(as a payload) or libpayload based payloads.
  • EC(Embedded Controller) => you do not have to touch it(just leave it where it is)


Non-free components replacements

  • Replace the non-free VGA option rom by making native graphics init work. submited for review. (see
  • Create a Native graphics<->VGA option rom. SeaVGABIOS (part of SeaBIOS) might be the answer. We need to look into that.
  • Make backlight work without the non-free option rom. See [1]

VGA Option ROM / VBIOS replacement (native graphics)

The VGA option ROM is proprietary. If you have an X60,X60s or X60t, GNUtoo (et al) has developed a free replacement which is under review, but you can use it right now:

Problems in native graphics code exposed by recent kernels

It was discovered that while this code seems to work fine on kernels older than linux 3.12.

On 3.12 and later kernels the i915 driver became unstable. Causing broken/glitchy 3D. and performance bugs.

The current suspicion is that linux had a bug which caused it to miss stolen memory altogether on this machine and hence disable parts of code. This bug was corrected in: 17fec8a08698bcab98788e1e89f5b8e7502ababd

Which was identified by git bisect, to be the cause of the driver crashes using native vga on the x60.

The native vga init code in coreboot needs to be corrected to have more engineered memory management. In the interim users have attempted running patched linux 3.12 kernels which revert commit 17fec. To apparent success.

Reported upstream in the Freedesktop Bugzilla as [How to file a good bug report?.

There is a fix now. [2] (for replay code) and has been adapted in libreboot. Apply the following patch on top of coreboot with 5320 or 5320+5345: patch. This was investigated by PaulePanter in coreboot IRC channel, notes were stored at: here and here

Enable backlight controls on X60 (with native gpu init instead of VGA ROM)

libreboot has changeset 5320 and 5345 from gerrit with backlight controls

Other things

Battery indictor in various DE's can be unreliable. (showing 50% available for instance, when fully charged). Using CLI tools to show battery info can show a sudden(brief) spike in reported power usage when disconnecting AC.

  • Add support for more batteries in ACPI.
  • Make the wifi card and/or the laptop produce less heat.
  • Finish and merge support for thinkpad_acpi linux kernel module
  • Sometimes some dock USB port aren't initialized => fix that
  • Fix that warning:
[   14.566817] ACPI Warning: 0x00000400-0x0000041f SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20130117/utaddress-251)

By using that advise:

<phcoder> GNUtoo-x60: in this case it looks like same range is declared twice in DSDT/SSDT



Without the VGA optiorn rom nvramtool says:

# ./nvramtool -a
nvramtool: coreboot table not found.  coreboot does not appear to
        be installed on this system.  Scanning for the table produced the
        following results:

            0 valid signatures were found with bad header checksums.
            0 valid headers were found with bad table checksums.

Fortunately there is a workarround:

# ./nvramtool -y ../../src/mainboard/lenovo/x60/cmos.layout -a
boot_option = Fallback
last_boot = Fallback
baud_rate = 115200
debug_level = Emergency
hyper_threading = Enable
nmi = Disable
# Bad value -> boot_devices
boot_default = 0x40
cmos_defaults_loaded = Yes
lpt = Disable
volume = 0xc
tft_brightness = 0xf
first_battery = Primary
bluetooth = Disable

"whining" (buzzing) noise when idle

Use "idle=halt" (higher power consumption) or "processor.max_cstate=2" (higher power consumption, but not as bad) kernel parameter in GRUB.

Note: Boot without these options, and there will be a high pitched noise coming from the board when the system is idle. A better workaround is to boot without these options, and run sudo powertop

Under "tunables", set all options to "Good" settings. This kills the noise. By using this, power consumption falls lower: near the levels in Lenovo BIOS (better battery life).

cbmem console

To get cbmem console working you need the non-free i915 option rom or native graphics(doesn't work yet, don't use) :fixed in master


When configuring coreboot with "make menuconfig" Go in console:

Console  --->

Enable it:

[*] Send console output to a CBMEM buffer
(0x20000) Room allocated for console output in CBMEM
(0xc00) Room allocated for console output in Cache as RAM
