iMac G3-Color Depth is 16-Bit(I believe), How do I change it?

Gadell: which iMac G3 do you have ?

[gadell]

I have "400 mhz blueish iMac (slot in CD one) with 500 Megs RAM." I'm actually running 8.04 LTS version, but it's sluggish and cannot see flash animations. It's my son's computer in fact.

But my last post was intended to be for someone called David who asks for help with his iMac running Xubuntu 9.10. He contacted me via private message and I was trying to switch to the thread.

[linuxopjemac]

and what machine does David have then ?

[gadell]

This is Davis's original message:

I am having display problems where the screen seems to be stuck in low color with my iMac G3 runniing Xubuntu 9.10, and I saw you posted a solution involving xorg.conf for someone who was having similar problems. So I was wondering if you could give me more detailed instructions (possibly step-by-step)because I am a Linux n00b and new to macs too.

Now I think that we have to wait for David to answer the questions and let us help him !

I have the First Slot Loader iMac G3 (350 MHz, 1 gig Ram) Oh and by the way I tried editing my xorg.conf file with the method the Gadell posted, but I'm not sure if I did it right, I basically just copy and pasted into the terminal.

I didn't really follow the thread, but I have a working Xorg.conf file for you:

So How do I use this? do I copy and paste into the terminal?

[linuxopjemac]

ok, sorry. I didn't know you were that kind of a n00b

in the terminal you do the following, first we copy your old config file to a new name and then we paste the info I gave you into the new Xorg.conf file:

sudo mv /etc/X11/Xorg.conf /etc/X11/Xorg.conf.old
sudo nano /etc/X11/Xorg.conf

now you enter an editor, just copy the file I provided you and you paste it into the editor.

then you need to exit the editor by typing CTRL-X, it will ask you to save it, type "y: for yes.

Then you need to restart X:

sudo /etc/init.d/gdm stop
sudo /etc/init.d/gdm start

hopefully you now enter a GUI.

The Only thing that I'm having trouble with now is the "Restart X" Part... Where do I type that?

[linuxopjemac]

in the same terminal program.
