Ubuntu 6.10 on Sony VAIO VGN-T140P

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.

I think I am going to redo the installation so that I can document the problems and solutions in greater detail. May be that will help someone who's facing similar problems!

State of Installation

I installed Ubuntu 6.10 on my Sony VAIO laptop about two weeks ago. Since then, I have installed umpteen modules/packages to get some functionality or the other working. Right from detecting the widescreen to being able to play MP3 files.

In the excitement of getting things to work, I did it in kind of an urgency. As a result, I don’t really remember which modules got working which functionality. The mode of operation was to google for the problem I had, then try out all the remedies various people suggested until one worked. I am pretty sure there are certain things I did that were not really needed. I want to start clean again and document the process. But looking back at it, it looks like a mammoth task.

So far I have used Synaptic Package Manager to install/remove all the packages. I wish there was something in the Package Manager that would tell me which packages I added since the initial install. Even better, it could export a list of packages that exist in my Ubuntu installation. Then I could import this file after a fresh install and get back to the state I am now. Similar could be done for .conf files that were added or modified.

Now, this may be wishful thinking or it may as well already in there somewhere. If it’s wishful thinking I think its a useful feature. If its already in there, I just haven’t found it yet. If you know something that does this, drop in a comment.

What’s your favorite OS?

Mac OS X is mine. Its not perfect – and I’ll blog about this in future – but it’s far better than alternatives available.

Linux is climbing fast on my favorite charts. I’ve been playing with Ubuntu6.10 (Edgy Eft) last few weeks. I am extremely happy with what I have seen so far. This distribution/version is the best I have tried.

High tech industry is my field of work, which means I deal with computers a lot at work. At home, however, I want to spend more time being productive using computers, not maintaining them. So I usually don’t want to spend a lot of time compiling kernels, trying out drivers, playing with .conf files to get things working.

In the past I have – on multiple occasions – given up on Linux when it came to Wireless LAN. It happened with more than one versions of Redhat, Fedora Core, Suse and some other distributions. So installing Ubuntu and getting almost everything working out of the box – including Wireless LAN – was a welcome surprise.

You gotta love Linux, its free, less (almost not?) prone to virus attacks, powerful. And now its easy to install and maintain. It a win-win.

Although it was the easiest Linux install so far for me, it was not a cakewalk. I’ll blog about the difficulties, problems and solutions in the future.
