Hello Ubuntu 12.10!!

Upgraded from 12.04 to 12.10 on Samsung Ultrabook Series 5. Can’t make my touchpad work… still fixing huhuhu

Update: I was able to make it work by doing these:

$ cd /usr/src/ $ sudo wget http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2 $ sudo tar jxvf psmouse-elantech-v6.tar.bz2 $ sudo dkms add -m psmouse -v elantech-v6 $ sudo dkms build -m psmouse -v elantech-v6 $ sudo dkms install -m psmouse -v elantech-v6

My touchpad works after that. I followed the instructions from here but after updating the kernel to 3.6 and rebooting, my webcam and wireless doesnt work. So I load up the previous 3.5 kernel.

You will notice that on the system settings, the “touchpad” is grayed out. You have to install:

$ sudo apt-get install xserver-xorg-core

… then multi-touch and touchpad settings will be back and working.

I can’t access my portable drive on Ubuntu 12.04 LTS because of exFAT file format

Just unplug your USB portable drive… then run these commands and plug-it again.

$ sudo apt-add-repository ppa:relan/exfat $ sudo apt-get update $ sudo apt-get install fuse-exfat exfat-utils

Ubuntu 12.04 missing system hibernate?

I upgraded my Lenovo 3000 V200 Ubuntu 11.10 to 12.04 just recently. And I noticed that my favorite “hibernate” is missing. So… I read and modified the kernel sources.. recompiled…… JUST KIDDING!!! I actually googled and found this thread (http://askubuntu.com/questions/94754/how-to-modify-policykit-to-allow-hibernation-in-upower) and it works!!

Just create or modify this file using your favorite file editor (vim works for me!)

/etc/polkit-1/localauthority/50-local.d/com.ubuntu.desktop.pkla

And put…


[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

A restart (power cycle) to apply the changes and then wooolaaa!!! “hibernate” is back!!
