Lenovo x121e i3 Linux Hardware Compatability

[connect404]

This thread's aim is to provide a single up to date source for hardware compatibility for the Lenovo x121e (in particular the i3 variant) laptop. There are a number of detailed threads around that already cover the generals about the hardware, but don't specifically deal with Ubuntu/Linux support. Please post any updates or revisions and I will keep this initial post up to date

Current BIOS/CPU:

daniel@racerx:~$ sudo dmidecode | grep Version
	Version: Intel(R) Core(TM) i3-2367M CPU @ 1.40GHz
	Version: 8QET53WW (1.14 )
	Version: ThinkPad X121e

Base OS:

daniel@racerx:~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 11.10
Release:	11.10
Codename:	oneiric
daniel@racerx:~$ uname -a
Linux racerx 3.0.0-14-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

Legend:
100% Supported (maybe with a patch)
A number of small bugs are present
Not Working
Untested




BIOS

• UEFI Boot support needs to be disabled in the BIOS for ubuntu 11.10
• Excellent BIOS with very very granular control for I/O, ATA Passwords, extra devices and CPU options

Webcam

• Full Native Support
• Skype, Cheese, etc all work 100%

Suspend to RAM / Suspend to Disk

• The laptop goes in and out of sleep/hibernate cleanly.
• No syslog error message or abnormnal behaviour after resume
• Wifi/Bluetooth returns to previous state on resume.

Multi Card Reader

• When returning from suspend the card reader no longer functions.
• Tested OK with an SD & SDHC card only.
  
• Booting from Memory cards need to be tested

Bluetooth

• Some inital issues with the card being hard blocked. Seems after an initial ubuntu install the card becomes blocked and you need to "Restore Defaults" in the BIOS and then reboot and things will magically work! This launchpad bug covers it in detail.
• After the initlal problems rfkill now shows the devices hard unblocked and switching via keyboard or software toggles soft block properly:

daniel@racerx:~$ sudo rfkill list
0: tpacpi_bluetooth_sw: Bluetooth
	Soft blocked: yes
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Fingerprint reader

• Untested

Intel Centrino-N Wifi

• Full WEP/WPA/WPA2 support
  
• Max Speed tests yet to be completed

Broadcom 1x1 B/G/N Wifi

• Untested but web reports seem to indicate it works
• Speed test & 'lspci -v' results needed

Broadcom 2x2 A/B/G/N Wifi

• Untested but web reports seem to indicate it works
• Speed test & 'lspci -v' results needed

Mechanical Hard Drive

• ACHI Support in BIOS for drives
• The hard drive accelerometer/impact sensor/protection system is not supported by hdapsd.

daniel@racerx:~$ sudo hdapsd -d sda
Tue Dec 13 18:31:19 2011: Starting hdapsd
Tue Dec 13 18:31:19 2011: Could not find a suitable interface

Touchpad & Keyboard Nipple

• Works well with Synaptic v1.4 included in base Ubuntu 11.10
• Two finger scrolling works by default
• Tap to click by default
• Two finger tap to right click works by default
• Touchpad lockout when typing works by default
• Keyboard Nipple and 3 buttons work 100%

Keyboard

• F1-F12 are the default action, with Fn being secondary
• Fn-* Mute, Volume, Brightness, Sleep work
• Fn-F5 keys work, but switch ALL radios to alternate state
• I had to unassign, then reassign the play/pause key to a function before it worked correctly.
  
• Fn-F3 untested
  
• Fn-F6 untested
  
• Fn-F7 untested

Sleep&Charge USB

• When enabled in the BIOS the yellow USB port will charge even when the laptop is either suspended or off

TPM Module

• Untested in Ubuntu as yet, but hardware detected

NIC

• Untested in Ubuntu as yet, but hardware detected

LCD

• Brightness works 100% and scale is fairly linear.
• Autodimm works
• After resume the bightness works 100%

Intel HD3000

• Intel video card is fully supported.
• Compiz is on by default and all desktop effects work great
• Full SD & HD (720p & 1080p) playback works 100%
• VGA & HDMI outputs can be configured as secondary or mirrored devices and detect/displays correctly.
• Have had this plugged into both a TV and LCD monitor and everything works flawlessly.

Intel HD Audio

• Sound playback through speakers works
• HDMI audio output works however it does not autoswtich and needs to be manually selected in the "Sound Settings" menu. After removal of the HDMI cable the output source needs to be changed back to "Analogue Duplex"
• Headset port switches from speakers to headphones and back correctly
• Headset port supports iPhone style headsets and mic input is passed through seamlessly.
  
• Digital 5.1 audio options in "Sound Menu" output tab need to be tested

Battery

• 65W Battery Stats are detected and displayed correctly
• Depletion rate seems to be accurate

I've been doing some initial power usage tests, these results are fairly objective at present.. but since only owning the laptop for 2 days I am yet to get a good feel for battery usage. I have been using powerstat to generate ACPI power usage. All tests are with:

• Bluetooth soft-off
• wifi connected to a wifi-N AP
• no AC connected
• 320gb 5400rpm HDD
• 8gb of RAM

Powerstat in the default mode will let the machine settle for 120 secs then take 30 samples over 5 mins and present the average. run from the terminal with: 'sudo powerstat'

Install powerstat with:

sudo add-apt-repository ppa:colin-king/powermanagement
sudo apt-get update
sudo apt-get install powerstat

When run on a stock x121e idling power consumption is

Summary:
 10.39 Watts on Average with Standard Deviation 0.10

Stock setup with echo SATA_ALPM_ENABLE=true | sudo tee /etc/pm/config.d/sata_alpm

Summary:
 10.28 Watts on Average with Standard Deviation 0.13

As above with "pm-powersave true"

Summary:
 10.01 Watts on Average with Standard Deviation 0.11

As above with kernel option "aspm=force"
edit /etc/default/grub (root privileges required) and change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force"
sudo update-grub

Summary:
  9.19 Watts on Average with Standard Deviation 0.16

All above disabled, then aspm=force turned on and TLP installed and setup. I recommend you read a bit about TLP.

sudo apt-add-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tp-smapi-dkms

Summary:
  8.61 Watts on Average with Standard Deviation 0.20

As above with i915 RC6 enabled
edit /etc/default/grub (root privileges required) and change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force i915.i915_enable_rc6=1"
sudo update-grub

I have noticed one random lockup since turning this on... well isn't really supported yet anyway so what can you expect

Summary:
  8.39 Watts on Average with Standard Deviation 0.14

At the time of writing I have got 4 hours of light duty web surfing and power manager says I have 1hr21m left @ 19% remaining. I think 5 hours of usage with the above settings is a fair estimate so far. More detailed usage reports to follow.

Hi,

Thanks for your installation report. I just recieve my x121e and everything is working out of the box with 11.10.

regards

[Daniel R.T. Hartley]

I've been running Linux Mint 11 on this since September. Generally extremely happy with it...

But a couple of weeks ago few expected issues of BIOS of motherboard/graphics have emerged causing resolution issues. xrandr commands, grub edit does not fix. Either that or it's a kernel bug.

Also, though you note the battery works fine, the x121e is quite seriously effected by the power regression issues with the currently available kernels, as many other lap tops do. More than a third of battery length is lost, and cpu temperatures rise, running at 10-15c hotter than with earlier kernels without the power regression (i.e. Linux Mint 11 and the kernel 2.6x rather than Mint 12 and the 3.x, which is going to remain that way until kernel 3.3. comes out).

The resolution issue (maybe completely unrelated to linux) is a total bummer, and the power regression issue is pretty much unacceptable.

But as a user, completely stable (with all updates).

I have found a small typo in one of the previous message: it is dkms and not dkm. The corrected code is:

sudo apt-add-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tp-smapi-dkms

The resolution issue (maybe completely unrelated to linux) is a total bummer, and the power regression issue is pretty much unacceptable.

I agree it does run a bit hotter than previous kernels, but 7 hours of usable battery life is on par with Windows7 reports.

I have found a small typo in one of the previous message: it is dkms and not dkm. The corrected code is:

fixed.

Also added an issue I've noticed. When returning from suspend the card reader no longer functions.

Hi,

I love this machine, but i am struggling with the graphics issues. I can put up with the odd artifact and i can deal with the icons sometimes behaving strangely in my file browser but the disappearing of lines of text while i am working in a text editor is infuriating.

If anyone knows a fix for this, i'd be grateful.

On the power regression issues, using some of the fixes provided above i can get my battery to about 6 hours - also using Jupiter.

Thanks,

[MorrisseyJ]

Using a Thinkpadx121e, running 11.10.

Sometimes when i start up in Ubuntu the track point doesn't initialise. The only way that i know to fix it is to reboot and try again. Usually it works after one reboot, but its still a hassle.

I was just wondering if someone knew a permanent fix for this or if anyone knows of a terminal command or something which could force the track point to initialise.

Thanks,

j
