Day in, day out…

I installed Beryl on my laptop that I just switched to Ubuntu Linux. It’s quite an eye candy! I am loving it so far.

Before I installed Beryl, I was worried how it will run on my computer - not a very powerful machine by today’s standards. It amazes me how well it works.

The installation was also a piece of cake. I followed the instructions on Beryl Wiki command-by-command. Beryl was up and running in less than half an hour.

Just one note. I tried both ways of configuring Beryl mentioned in the Wiki - one by setting up new session that uses startberyl.sh script and the other that uses the Sessions system preference to add Beryl as a startup item in an existing session. I found that the latter was a much better option - at least in my case. With startberyl.sh, I noticed very unpredictable behavior whenever I started a new session or came out of hibernation.

So, let me go back to playing with the stunning visual effects …

I mentioned in one of the previous posts that I will reinstall Ubuntu from scratch and document the process in more detail than I did last time. Well, here it is!

It took roughly couple of hours to get back to where I was after the last installation. There were the same issues as last time after a clean install, and I knew exactly what to do to fix them. More than week of googling and trying different things helped this install go much faster.

Before I reinstalled 6.10, I gave 7.04 alpha (the Feisty Fawn) a shot. It was good for most part, but had major issues with hibernate and response to power button behavior. I decided to go back to a more stable 6.10.

Output of lspci and lsmod are near the end of this post. And here’s the installation process:

Dual Boot

I wanted to keep Windows XP alongside Ubuntu on this laptop. So I partitioned the hard disc with Symantec Partition Magic 8. Created one Ext3 (approximately 13GB) and one Swap (little above 1GB) partition for Linux install. PM8 has the capabilities to create Ext3 and Linux Swap partitions.

Clean Install

I downloaded Ubuntu 6.10 Live CD image. Restarted the Vaio with the disc in the CD drive. Selected to ‘Run Live CD/Install’. After the desktop was up, I double-clicked on the install icon. That started the installation process. After answering a few easy questions, installation was on its way. Since I was using dual-boot, I had to make sure I am using correct partitions for Linux installation. This process took about 20-30 minutes.

After the installation process was done, I restarted the machine. On restart, I was given the choice to load Linux or Windows - I selected Linux (its all about making the right choice baby ).

Wireless LAN (WPA)

First thing I had to bring up was networking, so that I could install updates and modules I needed to fix other issues. I use WPA for authentication. I created /etc/wpa_supplicant.conf file with following contents:

    ap_scan=2
    network={
      ssid="myssid"
      psk="mypassphrase"
      key_mgmt=WPA-PSK
      proto=WPA
      pairwise=TKIP
    }

Then added following lines to the /etc/network/interfaces file:

    auto eth1
    iface eth1 inet dhcp
    pre-up wpa_supplicant -Bw -Dwext -ieth1 -c/etc/wpa_supplicant.conf
    post-down killall -q wpa_supplicant

After I restarted the machine, wireless LAN was up and running. I added the Network Monitor applet to to a panel to monitor the eth1 connection.

Widescreen LCD

The thing that was still bugging me was that widescreen aspect ratio of the screen was not being used. I had to install the 915resolution package to get that right.

I opened the System -> Administration-> Synaptic Package Manager and installed the required module (after the required authentication).

After a restart, widescreen format was automatically detected and configured.

Audio

The computer was silent after the clean install. I found some help on ubuntux.org that helped me resolve my sound related problem.

I opened the Volume Control by double-clicking on the speaker icon in the panel. Un-muted every control in ‘Playback’ and ‘Capture’ and put the slider control somewhere in the middle for every output and input. Then I went to Edit->Preference, checked ‘Headphone Jack Sense’, ‘Line Jack Sense’ and ‘External Amplifier’ boxes. Back in the main window under ‘Switches’, unchecked ‘Headphone Jack Sense’, ‘Line Jack Sense’ and ‘External Amplifier’.

That was all I needed to get the audio working.

Touchpad

I customized Synaptics Touchpad to suit me. I turned OFF right-top and right-bottom corners, they were causing unintentional right-clicks and pastes. This is how my InputDevice section in /etc/X11/xorg.conf looks:

Section "InputDevice"
  Identifier "Synaptics Touchpad"
  Driver "synaptics"
  Option "SendCoreEvents"    "true"
  Option "Device"            "/dev/psaux"
  Option "Protocol"          "auto-dev"
  Option "HorizScrollDelta"  "0"
  Option "RightEdge"         "950"
  Option "MaxTapTime"        "225"
  Option "MaxTapMove"        "160"
  Option "MaxDoubleTapTime"  "225"
  Option "SingleTapTimeout"  "180"
  Option "MinSpeed"          "0.40"
  Option "MaxSpeed"          "0.90"
  Option "AccelFactor"       "0.0060"
  Option "RTCornerButton"    "0"
  Option "RBCornerButton"    "0"
  Option "SHMConfig"         "on"
EndSection

Applications

Ubuntu 6.10 comes with a few applications that I usually use like, Firefox 2.0 and Gaim. Next, I installed all the applications I need for day to day work and fun. All these are available via Synaptic Package Manager

• gVim: Available in vim-gname package. I use the GUI version of vim for most of my editing/programming work
• Banshee: Available in code>banshee package. I found this to be a decent MP3 playback and music library management application
• Ogle: DVD playback on Linux is a big pain. No single application/plugin plays all my DVDs well. Ogle plays some that I created myself pretty well. But it couldn’t play the ones that I bought (encrypted?). Available in the ogle-gui package. I followed more instructions to use xine instead of gstreamer plugin for Totem, to play some DVDa that ogle does not play
• GNUstep: Framework, more than an application. I am learning Objective-C programming with GNUstep, so all my current fun projects use this. Available in gnustep-*devel* packages.

Like many blog posts helped me during my Linux installation, I hope someone finds this post helpful.

Output of lsmod:

Now, that’s a long list. I am sure there are some modules that I don’t use at all. How do I find out which ones? How do I stop them from loading?

Isn’t this fantastic!

First look at the prototype of BumpTop 3D Desktop looks pretty interesting. Let’s see how usable it really is when it is available for general use. What would be even better is the marriage of BumpTop and Multi-Touch Interaction technologies.

By the way, did you check out the bling on the presenter’s hand

I keep my wireless router (a D-Link DI-624) on the second level of my house. Almost always, I work on the main level. One of my computers is right under the router - kind of in a shadow area(?) The other place I usually work in not directly under - not so much in the shadow area.

Recently I noticed that the signal strength on the computer directly under was far inferior to that in other locations in the house. I wondered if that was because the antenna on the router happened to be in an upright position.

Just to try out, I tilted the antenna such that it is almost at 45 degrees away from the walls around. To my surprise, it improved the signal strength on the computer directly under from about 20% to 80%!!

And I always thought the antenna was omnidirectional…

UPDATE: Please refer to a more detailed account of this installation for more information

I recently installed Ubuntu 6.10 (The Edgy Eft) on my Sony VAIO VGN-T140P laptop. It dual boots with Windows XP Professional. This installation was the best Linux installation experiences I have had. But it was not as smooth as I had expected - as compared to Mac OS X or Windows - in that basic things should work out of the box. If I am trying to get a specialty video card or a TV tuner card to work, I can expect some experimenting and googling. I was expecting that with the standard hardware that is on this laptop, the installation would be a breeze - it wasn’t so.

Here’s what is working and what is not:

Widescreen

The laptop has a 1280×768 widescreen. Beginning with the Live CD Ubuntu did not auto detect it. I thought it would detect it when installation is done - it did not. The widescreen mode was not even in the options for me to set manually. I had to install 915resolution package to get it working. I used Synaptic Package Manager to install the package. After a restart, the widescreen was detected and properly set.

Wireless LAN

This was the sweetest surprise. Like I mentioned in an earlier post, I’ve had more than my share of trouble getting Wireless LAN working in the past. This time it was almost a breeze. Earlier I was using WEP shared Key authentication. I just had to do a little googling to learn that Shared Key does not work all that well. So I ended up using Open System. But later I switched to WPA-PSK TKIP authentication. I installed wpa_supplicant and edited the wpa_supplicant.conf to read:

ap_scan=2
  network={
  ssid=”my_ssid”
  psk=”my_passphrase”
  key_mgmt=WPA-PSK
  proto=WPA
  pairwise=TKIP
}

Wireless is working like charm since.

Audio

This was an unexpected hiccup. I always took audio for granted. I had never had to spend such a long time figuring this out. It turns out, the audio is muted by default! I had to start ‘/usr/bin/alsamixer’ and unmute the Headphone audio. Then in Volume Control preferences, make enough tracks visible so that headphone switch is displayed then check it. The audio works well now

DVD, MP3 Playback

Another shocker. I’d expect this to work out of the box. I had to try out Totem, Mplayer, gXine… install plugins I don’t even remember, to be able to play DVDs. Even MP3 playback wasn’t working out of the box. After unsuccessfully trying out plugins for Totem, Mplayer, Noatun, Rythmbox - I ended up installing xmms to get MP3 playback

Touch Pad

I customized Synaptics Touchpad to suit me. I turned OFF right-top and right-bottom corners, they were causing unintentional right-clicks and pastes. This is how my InputDevice section in /etc/X11/xorg.conf looks:

Section "InputDevice"
  Identifier “Synaptics Touchpad”
  Driver “synaptics”
  Option “SendCoreEvents” “true”
  Option “Device” “/dev/psaux”
  Option “Protocol” “auto-dev”
  Option “HorizScrollDelta” “0″
  Option “RightEdge” “950″
  Option “MaxTapTime” “225″
  Option “MaxTapMove” “160″
  Option “MaxDoubleTapTime” “225″
  Option “SingleTapTimeout” “180″
  Option “MinSpeed” “0.40″
  Option “MaxSpeed” “0.90″
  Option “AccelFactor” “0.0060″
  Option “RTCornerButton” “0″
  Option “RBCornerButton” “0″
  Option “SHMConfig” “on”
EndSection

Volume/Multimedia buttons

This is something that is still broken. What makes it worse is that I have no clue how to solve this. All the volume and multimedia buttons trigger an event with same keycode. There is no way of distinguishing between volume-up and volume-down buttons. Or any of DVD play/stop/Forward/Backward buttons.
