disable touchpad

Disabling X240 synaptics touchpad in thinkpad/lenovo. The problem is that the buttons are parts of the touchpad, so one can't just disable the whole touchpad.

  • sudo vi /usr/share/X11/xorg.conf.d/50-synaptics.conf
  • Change SoftButtonAreas within InputClass to Option "SoftButtonAreas" "64% 0 1 42% 36% 64% 1 42%"
  • add Option "AreaBottomEdge" "1" to disable the bottom of the touchpad
  • save and re-login

Qemu Linux Curses Guest

Framebuffer needs to be disabled with -curses, or you'll just get something like "1024x768 Graphics Mode".

Disable framebuffer module loading in Linux:

  • echo 'blacklist vga16fb' >> /etc/modprobe.d/blacklist-fdev.conf
Disable framebuffer in grub:
  • edit /etc/default/grub
  • update GRUB_CMDLINE_LINUX_DEFAULT="fbcon=map:99 text"
  • uncomment GRUB_TERMINAL=console
  • sudo update-grub

Proprietary JDK on Debian

In case you must use the proprietary Oracle JDK:

  • grab the JDK
  • sudo apt-get install java-package
  • make-jpkg downloadedpackage.tar.gz
    • may need to install some additional dependencies before this succeeds
  • install the package. e.g: sudo dpkg -i oracle-java8-jdk_8u92_amd64.deb
  • run update-alternatives for java if necessary

Resurrecting a T450 back to life

This probably holds also for other Lenovo Thinkpads.

Issue

Machine won't boot. Nothing seems to bring it back to life. Brick state.

Common fix

There is a small hole on the backside of the laptop. In T450 it's roughly at the other side of the touchpad. There is no text or symbol next to the hole.

You need to press the magic button in the hole.

This apparently resets something related to battery state.

Notes

You need have a correct combination of:

  • having or not having the battery
  • having or not having the charger connected
  • pressing the magic button before or after power button
This has worked at least three times for me so far.

Owl Lisp

Owl Lisp is a purely functional dialect of Scheme. It is based on the applicable subset of R7RS standard, and liberally extended with features necessary for functional operation. Owl can be used on most UNIX-like systems, such as Linux, BSDs and OS X. Programs are typically compiled via C to standalone binaries, so Owl isn't needed to run programs written in it.
