    Re: Help installing Ubuntu on eMac.

    After much experientation, digging around the internet and sifting through mountains of forum posts both here and elsewhere, I have found the magic line that will allow my eMac to use the default xserver with default ati driver using the internal display under intrepid. Under the "Device" section for your video card, you need to add the option "monitor-DVI-0" and point it to the name you gave for the monitor. My revised /etc/X11/xorg.conf file:
    Code:
    # xorg.conf (X.Org X Window System server configuration file)
    #
    # See the xorg.conf manual page.
    # (Type "man xorg.conf" at the shell prompt.)
    
    # This file is automatically updated on xserver-xorg package upgrades *only*
    # if it has not been modified since the last upgrade of the xserver-xorg
    # package.

    This is tested as working with a default install of intrepid ibex on an eMac 1.25Ghz (USB 2.0) with onboard ATI Radeon 9200. I still have not been able to enable desktop effects but I think this is a significant step in the right direction.

    EDIT: The reason I was unable to enable desktop effects was because I had enabled Compositing on metacity. Because of this, Compiz was unable to become the Compositng manager. After disabling compositing in metacity and rebooting, I was able to enable Advanced Desktop Effects. I now have an eMac running Intrepid using the "ati" driver and have flipping cubes and everything on the internal display. Bluetooth and Airport Extreme modules are also working.

    Re: Help installing Ubuntu on eMac.

    Nice report!

    You may have just solved quite a few problems for owners of more than just the emac. I think there are quite a few just running fbdev instead of ati so this might be just the ticket. Nice catch.

    It works great on Hardy as well!
    My wife is saying thank you, as I configured old eMac for her.
    Till now she had to use fbdev driver.

    Thanks!!!!! Good work!

    Re: Help installing Ubuntu on eMac.

    On my emac 700 - using snippets from other peoples xorg.conf files did not work.

    I read the xorg documentation online, and was able to get it to make it's own xorg.conf file, then adjusted a few settings to get the desired resolution. (needed to make a modeline, and adjust the available modes)

    This one really helped:

    and also:

    Re: Help installing Ubuntu on eMac.

    Using Kanji_Man's xorg.conf, I got my system to boot, but I don't think it is optimal. I can log in, but everything seems sluggish. Particularly anything graphics hungry, like playing avi files. I think that I need to fine tune my xorg.conf.

    Code:
    ant2ne@emac-ubuntu:/etc/X11$ lspci | grep VGA
    0000:00:10.0 VGA compatible controller: ATI Technologies Inc Radeon RV200 QW [Radeon 7500]
    This shows that Kanji_Man and I have different VGA devices. But it was my understanding the Identifier section is for user identification, not the computers.

    top doesn't show any process using more than 15% of CPU time. In fact it looks quite normal.
    free shows it could defiantly use more RAM but it doesn't appear to be using all of its swap.

    This defiantly has the feel of a system trying to display graphics that it is incapable of.

    So any hints on to what I should be changing in the xorg.conf? Or any other ideas why this system is so sluggish.

    Re: Help installing Ubuntu on eMac.

    Hi ant2ne,
    Here are some clues how to check whether everything is installed ok.

    I ASSUME you followed the instructions in this post.
    What comes to my head:

    1. Check, whether radeon driver is loaded. Type:

    Code:
    lsmod
    2. Try also glxgears whether it works.
    Code:
    glxgears -fullscreen
    I get around 78 frames in 1152x864 resolution.

    3. I installed xfce instead of gnome, it's a little bit faster.
    4. I use resolution 1152x864 - it's a little bit faster than the 1280x960.
    5. How much RAM do you have? For Gnome 500 MB is ok, for xfce less is fine.
    6. Firefox works really slow, when there are a lot of flash animations, but there is no help for this.

    Hope this helps.

    Re: Help installing Ubuntu on eMac.

    Thanks for the reply. I fixed this issue by upgrading my ram. I had 126 which simply isn't enough. I put in another 126 stick and the system responded better. But, i wanted to run XBMC and view adobe flash based sites (hulu) on this box, so I was forced to re-install OS X. The XBMC runs great on OS X. I'm still running ubuntu on my iBook though.

    Oswald, can you check if we have this xorg.conf file in our website? I think it's the Radeon emac one, right?
