Meego 1.1 on Aser Aspire One AOA 110

I've previously covered some to the modifications required to improve Meego on the Acer Aspire One. Having just reinstalled Meego 1.1 (note, the the no easy upgrade form 1.0, the recommended approach is a fresh install), here is a summary of the Meego AA1 tweeks.

Enable right hand side SDHC Card Reader
Add the following line to /etc/rc.local

/sbin/modprobe pciehp pciehp_force=1 > /dev/null 2>&1

Increase battery life
Add the lines suggested in the "Increase Battery Life" section at https://help.ubuntu.com/community/AA1/Using  to the end of /etc/rc.local

Fix suspend issue when SDHC cards are mounted
At the following line to beginning of /usr/sbin/pm-suspend

umount /dev/mmcblk*p*


Changes bfrfs settings for SSD usage
Modify /etc/fstab to change realatime to noatime and add the btrfs option ssd_spread

/dev/sda2 / btrfs defaults,noatime,nodatasum,ssd_spread 1 1

Reduce SSD disk IO use tmpfs
To reduce the disk IO use tmpfs for directories /tmp /var/tmp and /var/logs 
Add the following lines to /etc/fstab

tmpfs    /var/log    tmpfs    defaults    0 0
tmpfs    /tmp        tmpfs    defaults    0 0
tmpfs    /var/tmp    tmpfs    defaults    0 0

Put the browser cache in tmpfs
You can also put the Google Chrome or Chromium browser cache in tmpfs to prevent SSD IO that can slow down the AA1. Add the following line to /etc/fstab replacing the username with your login id

tmpfs    /home/username/.cache/google-chrome/Cache    tmpfs    defaults    0 0

Note: the directory location will be different for the Chromium version of Meego

You will want to clear out the existing cache data before rebooting

cd /home/username/.cache/google-chrome/Cache
rm -Rf *

Gaim Instant Messaging (IM) Client

Gaim is an excellent open source IM client that supports the main messaging platforms (MSN, Yahoo!, AIM, ICQ etc). Gaim does not support all of the fancy new features available in the main IM clients, but when it comes to plain and simple messaging Gaim is a winner for me. I largly use Gaim as my messaging client at work where I don't care for audio and video features and animated emoticons. There are also a number of Gaim plugin extenstions available. My personal favorite is the Guifications plugin in conjuction with the MSN Guifications theme which provides MSN messenger style popup notifications in the corner of the screen.

Video Conversion: Windows Media Center (MCE) DVR-MS to iPod Video

I treated myself to an iPod Video a couple of weeks ago, and after loading up my music collection I decided to try and move some recorded TV shows from my Media Center PC onto the iPod. The iPod won't play the Media Center recording directly, so they need to be converted to the appropriate video format, which is typically H.264 encoded video and AAC encoded audio in an .mp4 container. After much searching around and trying a variety of video conversion tools I settled on the following fairly straightforward approach using a couple of freely available applications. The first tool is used to convert the media center files to a non-proprietary format, and then the second step is to re-encode the video in a format suitable for the iPod. Step 1 - Convert the Windows Media Center DVR-MS recording to MPEG-2 video format Download and install the latest 1.1.0.x version of DVRMSToolbox (the 1.2.0.x versions are for Windows Vista only). Launch the DVRMStoMPEGGUI tool Start > All Programs ...
