Contents
CPU
The AMD CPU used on the X120e is microcode-upgradeable. To enable this functionality install the amd-ucode packages (available on extra) and add microcode to the MODULE list on /etc/rc.conf.
Video drivers
Users have the choice between the open source ATI video driver or the closed source Catalyst video driver.
In order to use the open source driver you must have at least kernel 2.6.38.
The open source ATI driver has flawless performance (including suspend). Gnome 3 works well with the open source ATI driver.
The Catalyst drivers do offer better 3D performance but usually have various minor issues (such as suspend support). As of kernel 3.2.6.2, suspend appears to work fine with this computer while using the catalyst drivers.
Wireless
The Thinkpad x120e is available with one of two wireless cards.
- The Realtek BGN Wifi card is currently supported out of the box by the rtl8192ce driver, which was integrated into the Linux kernel as of version 3.2. This card, however, suffers from access point association and connection stability problems, especially in meshed wireless networks due to poor wireless radius detection. Since driver development by Realtek effectively stopped as of January 2012, the general consensus among many owners online has been to swap out this wireless card for a different better supported half-mini PCI card such as the Intel 6230. This however requires a BIOS patch to remove Lenovo's hardware restriction on which wireless cards can be used in the computer. More information in regards to that can be found in this thread.
- The Broadcom ABGN Wifi card is currently supported by the b43 driver. This driver is recommended over the broadcom-wl.
Audio
The kernel modules work, but the HDMI audio is the primary device (not the speaker). You can swap that:
$ vim ~/.asoundrc
defaults.pcm.card 1 defaults.pcm.device 0 defaults.ctl.card 1
Note: Alternatively, you can accomplish the same thing by configuring the snd-hda-intel module:
$ grep snd-hda-intel /etc/modprobe.d/snd-hda-intel.conf
options snd-hda-intel index=1
By specifying index you should no longer specify the default in ~/.asoundrc
.
Input
TrackPoint scrolling (wheel emulation)
To enable scrolling with the TrackPoint while holding down the middle mouse button, create a new file /etc/X11/xorg.conf.d/20-thinkpad.conf with the following content:
Section "InputClass" Identifier "Trackpoint Wheel Emulation" MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|USB Trackpoint pointing device" MatchDevicePath "/dev/input/event*" Option "EmulateWheel" "true" Option "EmulateWheelButton" "2" Option "Emulate3Buttons" "false" Option "XAxisMapping" "6 7" Option "YAxisMapping" "4 5" EndSection
There are more details about how this works on the Xorg page.
Disabling the TrackPad
If you try to use your x120e lying down you will notice its very easy to hit the TrackPad buttons and invert the functionality of the other inputs(fun).
Install xf86-input-synaptics from the official repositories.
You can now toggle the TrackPads functionality using the synclient utility:
$ synclient TouchpadOff=0 ; enables $ synclient TouchpadOff=1 ; disables
If you want this to be permanent add the option to your /etc/X11/xorg.conf.d/10-synaptics.conf:
Option "TouchpadOff" "1"
Also, you can use this script for change touchpad status:
#!/bin/sh tstat=$(xinput list-props "SynPS/2 Synaptics TouchPad" | awk '/Synaptics Off/ { print $NF }') if [ $tstat = 0 ]; then synclient TouchpadOff=1 else synclient TouchpadOff=0 fi
TrackPoint speed and sensitivity
You can up your trackpoint speed with next command:
$ xinput --set-prop 13 'Device Accel Profile' 6
If you want this to be permanent speed up add the option to your /etc/X11/xorg.conf.d/20-thinkpad.conf (if this is your X11 trackpoint config, of course):
Option "AccelerationProfile" "6"
To more acceleration profile read man "xorf.conf.d"
Power saving
See power saving.
Disable Bluetooth
To save some power you can disable Bluetooth:
# tee <<< disable /proc/acpi/ibm/bluetooth
If you want to disable Bluetooth at every boot just add that line to /etc/rc.local
ATI video card powersaving
Under the opensource ATI video card driver you can control the clockspeed of the GPU. The recommended setting is:
echo dynpm > /sys/class/drm/card0/device/power_method
This enables dynamic frequency switching based off of GPU load. Further information on this topic can be found in ATI#Powersaving.
CPU undervolting
Using PHC
The Fusion Processor can be undervolted with the PHC-K8 tool. See PHC for usage information. For the AMD Fusion you'll want to download phc-k8AUR from the AUR.
"24 26 52" is what I have my E-350 set to. The three numbers represent 1600mhz, 1200mhz and 800mhz.
Using tpc
Another method for undervolting is tpcAUR. It is more intuitive then PHC tool and needs Kernelmodule cpuid and msr.
Information output available cores and current frequencies and voltage:
# tpc -l
Example how to use:
# tpc -set core all pstate 2 frequency 825 vcore 0.825 # tpc -set core all pstate 1 frequency 1320 vcore 1.2250 # tpc -set core all pstate 0 frequency 1650 vcore 1.3000
Fan control
The X120e's fan spins constantly but luckily can be controlled by the user.
To enable manual fan control place the following into /etc/modprobe.d/modprobe.conf
:
options thinkpad_acpi fan_control=1
Now you have to reload thinkpad_acpi module or reboot your netbook.
# rmmod thinkpad_acpi && modprobe thinkpad_acpi
Now it should look like that:
# cat /proc/acpi/ibm/fan status: disabled speed: 0 level: 0 commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds))
At this point the fan will still be safely under the system's control. You can either directly modify the values in /proc/acpi/ibm (NOT RECOMMENDED. e.g. 'echo level 1 > /proc/acpi/ibm/fan') or install a fan control daemon such as thinkfanAUR from the AUR.
Suspend and hibernation
Suspend works out of the box, but hibernate may fail - the system usually hangs with a black screen and a blinking power button led. To fix this we need to modify the hibernation mode; using pm-utils is just a matter of creaing a file /etc/pm/config.d/hibernate_mode containing a single line:
HIBERNATE_MODE="shutdown"
