I found a faster way to change your display from terminal.

To check what resolution does your monitor support type:

adamz@UBUNTU:~$ xrandr -q

It will show something like this:

adamz@UBUNTU:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA1 connected 1024×768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1360×768 59.8
1024×768 60.0*
800×600 60.3 56.2
848×480 60.0
640×480 59.9 59.9

Example I’m on 800×600 resolution and I want to change to 1024×768. I type this:

adamz@UBUNTU:~$ xrandr -s 1024×768

Thats it!

If you want to specify a refresh rate when switching your resolution, you can do it like this:

adamz@UBUNTU:~$ xrandr -s 1024×768@75

After upgrading my Ubuntu box I find that everytime I boot up I see alot of items on my GRUB list.

So I decided to delete the useless ones.

So just so that I wont forget next time here’s how I did it:

Hit ALT+F2 then type the following & run:

gksu gedit /boot/grub/menu.lst

i want to watch the full film of 127 hours online

Scroll down to the bottom of the page. Select & delete the ones you dont want.

Here’s a screenshot of my case:

(If you cant see the image then click to view larger size)

I deleted the ones that I have selected (highlighted) & “Save” the file.

Reboot & there you go. All those useless items are gone!

I finally decided to upgrade my 8.04 (Hardy Heron) to 9.04 (Jaunty Jackalope)

It’s AWESOME!! I love Ubuntu & I love linux OS! I can really feel the huge difference on 9.04 compared to 8.04.

Here’s a tutorial on How-To Upgrade to your latest Ubuntu distribution, in my case Ubuntu 9.04 using Torrent.

The first thing I did was:

hi-def quality the tourist

Go to http://www.ubuntu.com/getubuntu/downloadmirrors#alternate

Then, I download:

due date movie hd download

ubuntu-x.xx-alternate-i386.iso.torrent

* I assume that you are on i386 platform.

Since I do not want to waste my CD/DVD, i mounted the ISO file directly from terminal by typing:

movie going the distance on dvd

sudo mount -o loop /location/of/ubuntu-x.xx-alternate-1386.iso /media/cdrom0

And then from terminal, I typed the following:

gksu sh /cdrom0/cdromupgrade

watch new gulliver’s travels online

Lasty, we wait untill all the updating & installing is completed, restart your computer and there you go. Full upgrade yo!

Here’s a screenshot of my desktop:

As I was installing the latest WordPress on my localhost, I found out that my mod_rewrite wasn’t working properly. So What I did was first I typed:

sudo apache2ctl -l

a fistful of dollars full movie online

To know if this module is already loaded. Turns out it’s not, so what I did after that was I typed in:

download divx paranormal activity 2 movie

a2enmod rewrite

To enable the mod_rewrite module. So i tested accessing my localhost link and it didn’t work. I checked back by typing the first command line and it says that the module isn’t enabled yet. So what I did next was I typed in:

inglourious basterds the movie

sudo gedit /etc/apache2/sites-available/default

movie groundhog day online

legend of the guardians: the owls of ga’hoole movie to buy

Then I looked for AllowOverRide and change it from None to All

I restarted Apache2 by typing:

sudo /etc/init.d/apache2 restart

And everything works perfectly fine! My mod_rewrite is working!

Here’s a simple tutorial for setting up Synergy with Ubuntu as client and Vista as Server

I have a CPU running on Ubuntu and a Laptop running on Vista. I use my Ubuntu box as a test server for my projects while Vista for my daily use. My monitor is placed on my left side and my laptop on the right.
