Ubuntu 7.10 Desktop Effects

Finally, the desktop effect is working on nx8220 based on the guide provided by following link:
http://ubuntuforums.org/showthread.php?t=585045

here is the command:

Code:
sudo gedit /etc/X11/xorg.conf
Skip down to the bottom and find the lines like this:
Code:
Section "Extensions"
Option "Composite" "0"
EndSection
it may say "disable" rather than "0". Change the 0 or disable to 1 so it reads:
Code:
Section "Extensions"
Option "Composite" "1"
EndSection


Code:
sudo apt-get install xserver-xgl
logout and login again.
Code:
sudo apt-get install compizconfig-settings-manager

Configure Ubuntu startup

If the startup screen resolution is incorrect, it can be fixed by using startupmanager.

sudo apt-get install startupmanager
sudo startupmanager


The vga modes are:

Ubuntu 7.10 on HP nx8220

I successfully installed Ubuntu 7.10 on nx8220. Initially the wireless is not working but after some try and error with different setting, i finally get it working.

I installed powertop, although I'm not sure how to use it, i just accept all it's suggestion, eg turn off bluetooth, etc. it should help to reduce the power usage on my laptop.

So far so good, only issue is during boot up/shutdown, by screen just went blank, again i think is something to do with my configuration. I'll try to google for the solution when I have free time.

Ubuntu 7.10 on vmware

I have setup ubuntu 7.10 on vmware. Everything went smoothly with a few glitches. here is the work around:

1. wrong resolution during boot up:

> sudo /etc/init.d/gdm stop
> sudo dpkg-reconfigure xserver-xorg
> sudo /etc/init.d/gdm start


or hacking on /etc/X11/xorg.conf of regenerating it, change screen resolution, add following lines in screen section

SubSection "Display"
#Modes "1280x1024" "1280x800" "1024x768" "800x600"
Modes "1280x800" "1024x768" "800x600"
EndSubSection

2. if scroll wheel not working, hack /etc/X11/xorg.conf and change mouse protocal to imps/2.


That's all, after that, everything is perfect!!

Next, setup VPN to my office. I use following guide:
https://help.ubuntu.com/community/VPNClient

but failed to connect if I'm using NAT, it only work in bridge mode.
