I recently installed a fresh copy of lubuntu 11.04 powerpc on my computer. I was following the instructions from this fourm post: http://ubuntuforums.org/showthread.php?t=1798792 All I get is the command-line prompt. I try to start X by running "startx" with no avail.

I googled for about 2 hours and there has been no success.

I have an Mac G4 800mhz 832mb ram 5400rpm 10gb and 37gb seagate internal HDD.

alexy13 - try adding xforcevesa to your grub boot string - this should give you a usable graphical desktop. –  fossfreedom Aug 25 '11 at 14:41
    
I never see the grub, how can I add it to the grub boot string? –  alexy13 Aug 25 '11 at 14:51
    
... oh yes - powerpc... its not grub its your yaboot.conf file as per the wiki wiki.ubuntu.com/PowerPCFAQ - n.b. look towards the bottom of the wiki-page. Alternatively (or perhaps better?) specify "vesa" instead of "ati" in your xorg.conf –  fossfreedom Aug 25 '11 at 15:01
    
alexy13 - your xorg.conf file looks very complicated - can you simplify it? - the forum link recommends "1 device section, 1 screen section, 1 monitor section " –  fossfreedom Aug 25 '11 at 15:14
    
I just updated my first post with new errors and a new Xorg.conf file –  alexy13 Aug 25 '11 at 17:17

Second Try

avtolle has reported to make an iMac with with an ATI Rage 128 device (looks like yours) to work by adding this lines at the xorg file:

  
Section "Monitor"

Horizsync 28-51
Vertrefresh 43-60


Section "Screen"
SubSection "Display"
Modes "1024x768"
EndSubSection


Section "DRI"
Mode 0666
EndSection  

Also you could change the Modes "1024x768" to yours (1152x870). Be careful with this because setting a bigger resolution than your card support has been report to break the monitor.

First Try

Do you know the specs of your monitor?

Have a look at this:

"

Message: "Screen(s) found, but none have a usable configuration"

You get an error message:

(EE) Screen(s) found, but none have a usable configuration.  
Fatal server error:  
no screens found  

In most cases this means there are no video modes available for your configuration. Each entry in the list of specified or default video modes gets checked if it lies withing the limit or the hardware: if it lies within the sync range specified or probed for the monitor, if it will work with the memory available on the video card or if the pixel clock lies within the range supported by the chipsets. There are many more limits. For each rejected mode you can see in the log file the reason for rejection:

...
(II) VGA(0): Not using default mode "320x200" (vrefresh out of range)  
(II) VGA(0): Not using default mode "720x400" (insufficient memory for mode)  
(II) VGA(0): Not using default mode "360x200" (hsync out of range)  
...  

In most cases the monitor ranges are the reason why your modes where rejected. Please try to extend these ranges carefully until you get a working mode. Please note: on older monitors you need to be careful extending the ranges as it can be easily destroyed. There may be other reasons why you get this message.

If the specified depth is not supported with your hardware.

In this case try depth 8, or if you are using the vga driver even depth 4. If you specified a combination of options the driver cannot handle.
If loading of a required sub module wasn't successful. In this case you'll get a message that the loading failed. Please try to investigate, why. The message may give you a clue: you may be using the wrong version of the module, or the file may not exist.

"

The "default" one is 1152x870. How would I be able to change that file? –  alexy13 Aug 24 '11 at 17:27
    
Can you check if a file like /var/log/Xorg.0.log exists and post here? The usual locations of the configuration file are: /etc/X11/xorg.conf or /etc/X11/XF86Config-4. –  desgua Aug 24 '11 at 17:32
    
I cannot post the file right now because I am occupied and will be for a long time :(. It might be a while.... How would I post it if I'm in command-line only mode? (Right now I'm using another computer) –  alexy13 Aug 24 '11 at 17:35
    
You could just check if the 1152x870 was tested at the log file. I will have to leave, but I will come back soon. –  desgua Aug 24 '11 at 17:38
    
I updated my question. –  alexy13 Aug 24 '11 at 19:23

The error in your latest edit is due to a missing monitor section:

Can I suggest the following simple xorg.conf based on the values you have given:

Section "Device"
    Identifier  "Configured Video Device"
    Driver      "ATI Technologies Inc Rage 128 PF/PRO AGP 4x TMDS"
EndSection

Section "Monitor"
    Identifier  "Configured Monitor"
    Horizsync   24-82
    Vertrefresh 56-85
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Monitor     "Configured Monitor"
    Device      "Configured Video Device"
    Subsection "Display"
       Modes    "800x600" "1024x768"
    EndSubsection
EndSection

Section "DRI"
  Mode 0666
EndSection

If you dont have the correct Driver "ATI Technologies Inc Rage 128 PF/PRO AGP 4x TMDS" value try "vesa" instead

I'm giving up. Three weeks of troubleshooting, this is too much. I decided to install Ubuntu on a virtual box on my iMac. Then I deleted it because it was having issues with unity and after 2 days of trying to fix it, I gave up, again. Thank you for all of the help that I received, because it did help.

Hi, Mac. Long time no see.

Adding Option "NoInt10" "true", and setting "UseFBDev" to "false" works for certain, however you get a particularly sluggish system. The problem has to do with the fact that r128 support has been pulled from mesa-gl, and usually ubuntu pulls it from the distro as well. To solve this last problem I had to recompile a kernel with the rage 128 compiled as a built-in "driver". I now only have a problem with udev, which I currently workaround by stopping it with: sudo stop udev.

The following xorg.conf made my xserver work without recompiling a kernel, sluggish is better then nothing for now:

Section "Device"
    Identifier      "ATI Technologies Inc Rage 128 PF/PRO AGP 4x TMDS"
    Driver          "r128"
    BusID           "PCI:0:16:0"
        Option      "UseFBDev"      "false"
        Option      "NoInt10"       "true"
        Option      "Display"       "CRT"
EndSection

There you can find a working xorg.conf

As I pointed out yesterday personally I feel the best solution for you would have been to post on the actual thread. It is important that people let me know if they are having problems with the guide. Maybe I have got something wrong or perhaps could explain it better?

You say you are using a non standard external monitor. Therefore it is inadvisable to use an xorg.conf that you just found 'on the internet'. If I am reading correctly you first tried to configure your own xorg.conf so that is good. However, it is also useful to have a look at what other people do if you run into problems. Have a look on the linked site in the guide which has many sample xorg.conf files.

As previously advised you only need 1 of each section. So shortening your orginal xorg.conf I get this:

Section "ServerLayout"
    Identifier     "X.org Configured"
    Screen         "Screen0"
EndSection

Section "Monitor"
    Identifier   "Monitor0"
    VendorName   "Monitor Vendor"
    ModelName    "Monitor Model"
EndSection

Section "Device"
        ### Available Driver options are:-
        ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
        ### <string>: "String", <freq>: "<f> Hz/kHz/MHz",

If that doesn't work then try the following option in your device section:

Option "UseFBDev" "False"

Some people seem to use this too:

Option "NoInt10" "True"

For further queries please post on the thread/guide, but it seems you have given up so this answer maybe redundant anyway. I hope you give lubuntu or xubuntu another try on your powerpc. The apple forum has a lot of information on it for you to tap into.
