Help installing Ubuntu on eMac.

[crapple]

I am glad it worked for you. I am posting a solution on how to get interpread to work with emacs. What you need is a hardy or earlier xorg file. Under driver for the graphics card instead of ati switch it to fbdev and it works like a charm except for desktop effects.
Hope this helps if you want to try interpread

To get sound working you need to run

sudo modprobe snd-powermac

Then to get sound working automatically you need to do this

sudo nano -w /etc/modules

then add

snd-powermac

to the list.

Then restart and sound should work.

Thank you Crapple. Now I have sound working on my emac too in Ubuntu 8.04.1.
By the way,

sudo modprobe snd-powermac

did not work on Ubuntu 8.10, there was no sound, but 8.04.1 is fine so far.

[crapple]

It works in interpid after you add it to the modules list and restart.

[kububa]

Yes, Crapple, I confirm, sound is working on Interpid as well. Thanks!

Another question: on Interpid my eMac box works only with fbdev driver, it's fine for me as I do not need 3d acceleration, but I do not know how to change resolution. It seems to me that changing xorg.conf is not effecting on the system. To change the resolution I calculated Modeline on this page http://www.arachnoid.com/modelines/ and pasted it to xorg.conf.

Modeline "1152x864_80.00" 112.36 1152 1224 1352 1552 864 865 868 905 -HSync +Vsync

Then I added

Modes "1152x864" "1024x768"

in my Screen section of xorg. But nothing changed after restarting. I can not change resolution in gui either (System>Preferences>Resolution).
On Ubuntu 8.10 on my macmini with Intel processor I found the monitors' configuration file under /home/username/.config/monitors.xml.

Does anyone knows how to change resolution to 1152x864?

Kubaba, sudo apt-get install read-edid, then type

# sudo get-edid | parse-edid

This might help you write a working modeline for your particular eMac.

This is the output on my eMac 2005 Radeon 9600:

parse-edid: parse-edid version 1.4.1
parse-edid: EDID checksum passed.

EndSection

Then again, I don't see 1152x864 from this output...

Just to know, I got this info from an old post here: http://ubuntuforums.org/showpost.php...3&postcount=13

Also,

I wish I could upgrade my eMac past Feisty, but I really don't want to force old drivers or use fbdev. Is there an xserver-xorg-video-radeon on Intrepid or later that actually works with my eMac? I'm using the built-in CRT - not any external monitors, if that helps.

[kububa]

geopgeop, thanks for your tip. However, it's interesting that sudo get-edid | parse-edid is not showing 1152x864 resolution, as I can choose this resolution in Mac OS on my eMac.
Another thing is, changing resolution in xorg is not affecting computer when using fbdev driver.
I'm also looking forward to working ati driver again for my eMac, but it probably this time will never come... Or maybe?
There is a bug described here:

[kerryhall]

Is it possible to get hardware OpenGL acceleration on an eMac?

[kerryhall]

Try this.
Good Luck!

Yo, Crapple, that worked like a charm!! I tried running glxgears, and I got something like 220 fps, but it looked choppy.

Is there anyway to get non-choppy OpenGL going on my machine? (It's identical to yours I believe)

Thanks!

Thanks to this and other threads I was recently able to install intrepid ibex on my eMac 1.25Ghz (USB 2.0). Here is the overall process:

- Boot the ubuntu-8.10-alternate-powerpc.iso
- When you get the text menu for language selection press CTRL+ALT+F2 for a secondary text console.
- At the busybox prompt enter "modprobe ide-scsi" to wake up your optical drive so that it can be detected.
- Type "exit" and then CTRL+ALT+F1 to return to the installation

- Complete the text-mode installation process for Ubuntu.

- When the system reboots wait to get past the bootstrap, yaboot and the splash screens. Then the screen will flicker and go blank.
- Press CTRL+ALT+F1 for a text console.
- Login with the account you created during the ubuntu installation.
- Enable sound by using the command "sudo nano /etc/modules", add the line "snd-powermac" (without quotes), then CTRL+X to exit and save.
- You can install the ati xserver with the command "sudo apt-get install xserver-xorg-video-ati"
- Use the command "sudo nano /etc/X11/xorg.conf" to edit the X configuration. The default intrepid configuration is empty as it tries to autodetect everything. Replace it with this (easier to copy from a mounted flash drive):
- Again use CTRL+X to exit, then save.

SEE UPDATED INFORMATION ON NEXT POST

- Use the command "sudo shutdown -r now" to reboot the system and you should now have an eMac running a basic install of Intrepid Ibex with functioning sound and a decent resolution.

-I have not been able to enable desktop effects (aka compizfusion) however you can enable basic compositing under metacity with this command:
gconftool-2 -s '/apps/metacity/general/compositing_manager' --type bool true
