Posted August 2nd, 2007, in: old iMac G3| Technology| Ubuntu/Xubuntu/Linux

Thanks to this thread on the ubuntu forum I was able figure out what was going terribly wrong with my attempt to start up xubuntu on an old G3 I want to keep alive.

Basically, the default display setting need to be changed through the linux terminal or you boot up to a blank black sceen. First I found this from the forum:

1. ctrl-option-F1 (should give you a command prompt)
2. type: sudo nano /etc/X11/xorg.conf (return)
3. make your edits (see below)
4. ctrl-O (return) to write edited file
5. ctrl-X to exit nano back to command line
6. type: sudo /etc/init.d/kdm restart (return) to restart KDE

At the very least you’ll need to modify “HorizSync” to 60-60 and “VertRefresh” to 75-117. Both are in the monitors section.

If you restart KDE and everything is in extreme slo-mo, you’ll also need to edit xorg.conf to disable DRI (in the modules section, put a hash mark (#) at the beginning of the line containing “load dri”).

…but I didn’t have KDE, knowing a little more now I was able to find this

sudo killall gdm

then

sudo gdm start

Then, I didn’t have the login for Xubuntu, so I was able to find this:

control option F1

sudo adduser yourusername

answer the questions and your password when happy y to accept.

sudo killall gdm

then

sudo gdm start

Someone named Brandon Stafford has additional information that it looks like I may need as I go forward.

1. Put the Breezy Badger for PowerPC install disk in the CD drive.

2. Reboot.

3. At the first prompt, type “server” and hit return. This will install everything in normal Ubuntu install except the GNOME desktop.

4. Install the Xubuntu desktop and the GNU display manager using apt-get:

sudo apt-get install xubuntu-desktop gdm

5. To get the graphical interface working, I had to tweak /etc/X11/xorg.conf a little. The first change was to alter the HorizSync and VertRefresh settings. I also switched from the fbdev driver to the ati driver. The snippet below shows the original settings commented out and the new settings added. (Link to full xorg.conf.)

Identifier “Generic Monitor”
Option “DPMS”
# HorizSync 28-51
# VertRefresh 43-60
HorizSync 60-60
VertRefresh 43-117
EndSection
6. The last tweak was to add a printer to CUPS manually. To enable the web administration for CUPS, I added a root password:

sudo -s

passwd

In /etc/cups/cupsd.conf, I changed RunAsUser to No, so that CUPS would run as root, and not switch to run as the user cupsys, as I believe this is what disables the web interface:

RunAsUser No

Then restart CUPS:

/etc/init.d/cupsys restart

Here is what ended up in /etc/cups/printers.conf: (Yes, I live in a farmhouse, and I work on Sunday nights)

Overall, Xubuntu is working really well– much better than OS 9.2. It’s only got 64 MB of RAM, but Firefox runs surprisingly well. I plan on maxing out the memory when I get the chance.

The Xubuntu people have been planning on releasing a CD version of Xubuntu coincident with the release of the Dapper Drake in April. I found the XFCE file manager, xffm, to be a little squirrely, and I couldn’t get it to connect to our file server through Samba; maybe that will work in the next release, or maybe I will have figured out how to configure Samba. The Dapper release of Xubuntu will likely be based on XFCE 4.4, which will allegedly include the first release of Thunar, XFCE’s new file manager.

Hmm. If Thunar is good, I might switch to Xubuntu entirely. So far, XFCE seems like a fast version of GNOME to me, and I spend most of my time in Firefox and a terminal window anyway.

and this too:
