How Can I Speed Up Ubuntu Without Reducing Movie Quality ??
 
I followed a tip to reduce color usage on my ubuntu 7.10 in order to improve my computer's speed. The tip called for entering 'sudo gedit /etc/X11/xorg.conf' in terminal and changing the color depth from 24 to 16. In doing so, my computer actually ran a lot faster. But, when I look at a movie, it comes out very pixelated. I then changed the color depth back to 24 which makes it sluggish to being with. Is there a way I can reduce the color depth without sacrificing movie quality?

Jomen, if you're reading this, I hope you can help me with this one.

First lets find some info on your machine:
Code:
lspci -v
Then look in /etc/X11/xorg.conf or in /var/log/Xorg.0.log for info on what driver for your video card is in use.

Code:
less /var/log/Xorg.0.log
to scan manually throug the whole thing
Code:
less /var/log/Xorg.0.log | grep chipset
might find it faster
You can use any editor instead of "less" - but it is a quicker way to me.

[edit]
while we are at it - please also post the output of this command:
Code:
less /var/log/Xorg.0.log|grep '(WW)'

Hi, jomen. Thanks for replying. I upgraded to 8.04 yesterday, just to let you know. Here's info from lspci -v:

If you think there's a need to upgrade my video driver, I would welcome that. It would be great to upgrade it if I need to. Let me know, and thanks for everything, jomen !!!!
