How to Remove Old Linux Kernels

Sometimes /boot is so limited, and tend to forget to do housekeeping. Here goes

dpkg --list | grep linux-image |awk {'print $2'}|grep -v "`uname -r`\|linux-image-generic"|xargs apt-get purge -y

Disable touchpad for laptop

I got problem with my touchpad.. it let the cursor jumping here and there .. so it's very annoying.

Here is the tips that I found out from the Internet

xinput list | perl -ne 'if ($_ =~ /Synaptics/) {exec "xinput","set-prop",substr($_,3+index($_,"id="),2),"Device Enabled","0"}'

You may change /Synaptics/ with any value that pointed to your device from "xinput list" command

Move windows control (min, max, close) button to the right

Worked from 12.04 - 13.10 (the original author said this, I tested on 13.10 and worked)

gsettings set org.gnome.desktop.wm.preferences button-layout ':minimize,maximize,close'

Borked with Error during Make Menuconfig in Kernel Compile?

Modifying an erroneous visudo file and cannot get into sudo

I recently modified the visudo file and turns out I can't get into visudo mode at all. Worst is that in Ubuntu 12.04 we can't use "su" command or log in as "root"

Here is the tips, from here

Use pkexec command,

Just type "pkexec visudo"

And modify or restore back to the original settings.

Disable auto mount from USB device

I have a problem with my Galaxy Nexus before and now my LG Nexus 4 - they keep pop up the nautilus if I insert the plug to the cable (I prefer charging my phone to the laptop).

So here is the solution, which finally I found from here


Go to your terminal, type dconf-editor. The find "org.gnome.desktop.media-handling.automount-open"

And choose your preferred choice, mine is like this:

As I prefer the phone being automounted, I just feel annoyed with the nautilus pop up, hence I untick "automount-open" but choose "automount" and "autorun-never" instead.

I feel the autorun function is so Windowish.. and wondering why it ever exists. Not that it is bad.. but for me it is less preferred.

Changing Maximize, Minimize and Close Button from Left to Right in Unity

I am currently back to Ubuntu 12.04 due to stability issue with 12.10

But the problem is with the buttons. So here goes


gconftool-2 --set "/apps/metacity/general/button_layout" --type string ":minimize,maximize,close"



This will set these buttons to right pane of your windows :)

Customizing Workspace Navigation Shortcuts Using Gsettings

I got a problem in my Ubuntu 12.04 LTS, since the configuration that I saved using the gnome-setting interface did not worked (as if it was never saved).

So I decided to google around and found this tips which I already customized to my enviroment:

gsettings set org.gnome.desktop.wm.keybindings     switch-to-workspace-1 "[\"Q\"]"
gsettings set org.gnome.desktop.wm.keybindings     switch-to-workspace-2 "[\"W\"]"
gsettings set org.gnome.desktop.wm.keybindings     switch-to-workspace-3 "[\"E\"]"
gsettings set org.gnome.desktop.wm.keybindings     switch-to-workspace-4 "[\"R\"]"

Here, I used Alt with for workspace 1-4

Cinnamon untuk Ubuntu 12.10 Quantal

Bagi pengguna Cinnamon seperti saya (yang biasa menggunakan environment ini di dalam Linux Mint), tentunya menginginkan kosmetik yang sama di dalam Ubuntu 12.10

Ia boleh diperolehi dari laman PPA di sini

Secara ringkas:

sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable 
sudo apt-get update
sudo apt-get install cinnamon 

Pasang kernel terkini dari PPA

Kernel terkini memang mengujakan, selain dari "bragging right" untuk ada kernel terbaru, ia juga berguna untuk menguji ciri-ciri terbaru pada kernel yang ada di dalam git.

Selain dari kompil sendiri dari git, kita boleh pasang kernel terbaru dari PPA di sini.

Option linux-image-extra, menurut komen di sini adalah untuk kernel yang mengandungi driver-driver seperti untuk KVM dan Virtualbox.

Selamat mencuba!

Ubuntu 12.10 dilancarkan

Ubuntu 12.10 telah dilancarkan. Antara pembaharuan yang dibawa ialah fungsi Amazon search di dalam versi kali ini. Untuk membuang fungsi carian tersebut anda boleh rujuk blog ini

Pendek kata guna arahan:

sudo apt-get remove unity-lens-shopping

Buang kernel lama selepas upgrade

Run ni dulu:

 dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d'

Bila dah yakin, baru run:

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge

Pastikan anda faham apa yang anda lakukan, segala risiko tidak akan saya tanggung.

Mount HFS+ partition sebagai read/write

Secara default jika kita mount partition Mac yang menggunakan filesystem HFS+, ia hanya akan beri permission "read only"

VNC dari Mint(Ubuntu) ke Ubuntu

mac dalam bilik, laptop dalam study room. sebab nak akses current desktop.. thinking of guna VNC. so install tightvnc. sebab malas nak config, each session created by VNC server occupy port 5901...5902.. which is not default.

akses pulak guna xtightvncviewer.. akses default port 5900. otherwise kena specify host:. solution. guna x11vnc utk create vnc session, akses guna xtightvncviewer.

mmg awesome x11vnc ni.. very lightweight.
