The accepted answer does not work on my new Lenovo T440s. Apparently the firmware changed. Following http://www.thinkwiki.org/wiki/Tpacpi-bat, I did git clone https://github.com/teleshoes/tpacpi-bat.git cd tpacpi-bat/ ./install.pl sudo ./tpacpi-bat -s ST 1 15 # load internal battery when below 15% sudo ./tpacpi-bat -s SP 1 95 # stop charging at 95% sudo ...

what I understand that you have to change Fn-F9 from toggling airplane mode to toggling wireless ,, I suggest that 1) Disable Fn-F9 from toggling airplane: open dconf-editor (install it if not) and search for WLAN (press ctrl + f and type WLAN) then it's up to you to change the binding if you find it 2) Bind Fn-F9 to toggling wireless as in my other ...

In addition to Matt's answer, it should also be noted that the Fn and Ctrl key usage can be swapped in BIOS (see image below). This may have been set if the Fn key doesn't seem to behave as you may expect. It may also be very useful to know, as at least personally having Ctrl nearest the edge is more practical than having the Fn key there.

I finally got it to work with the following workaround: I just removed the whole folder /lib/udev/rules.d/69-wacom.rules/ (Actually I moved it to my Desktop just in case I need it again.) Then I added the following file (named 69-xserver-xorg-input-wacom.rules) instead of the removed folder (I have copied the file from the ubuntu installed on my lenovo X61 ...

Just wanna throw this out there. I have a Lenovo B50-70 and wireless crashed all the time. It was active for a while on a fresh boot-up, and it just timedout after about 10 - 15 minutes or less. What worked for me, was: $ sudo apt-get remove --purge avahi-daemon resolvconf You can also add new nameservers in your /etc/resolv.conf $ sudo vi ...

Updating the kernel works for me, but not completely. I think the device drivers need to reach a stable state yet.

Try this. This would work. http://www.richxiong.com/2012/11/system-freeze-on-ubuntu-12-04-64-bit/ If this is not working it is a bug. Please refer to this article. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1174275

EDIT: maybe i got the solution. The problem seems to be cpufreqd (daemon) wich was installed after update. I removed it and instlled acpi (although the acpid was still there)... So, removing cpufreqd seems to solve my problem

Error message you got seems clearly telling you what's wrong no?; you don't have TPPS/2 IBM TrackPoint on your machine. What if replacing it with ThinkPad Extra Buttons that's printed in your xinput output? Atually I've got my middle-button working by following the link you provided. In my case: $ xinput ⎡ Virtual core pointer id=2 ...

@vitaly-dubyna has the right answer. On debian his method works flawlessly. To make your life easier, put a file .xsessionrc in your home directory with all the settings so that it will be loaded after each restart. make a new file use vim, pico, gedit -- vim .xsessionrc then stick this inside xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel ...

There is no hardware switch on this particular model, just a key on the keyboard which activates the wireless feature. Press F9 to enable or disable the wireless feature.

I have a T440s and may be its the same thing: the keyboad top row has two modes, the direct key and the "Fn" + key. You can switch between the two modes by pressing Fn + FnLk (Esc key on my french keyboard). On my Fn key, a light indicates the mode: when the light is on, I have the F1, F2... in direct mode and I must press Fn to access the special functions ...
