The xorg.conf files on that site are garbage. The one you have downloaded is a prime example. I would advise you not to use them.
The above xorg.conf uses the fbdev driver - a generic unaccelerated driver. You should only use it as a last resort.
Have you tried turning off KMS? - http://

Thank you for the suggestions, I'll try that. I simply went with what
worked and in so doing ended several days of frustration.

Please read the new comments on the ubuntu forum thread. If you still have problems with video=ofonly radeon.agpmode=-1 then please attach an Xorg.0.log plus dmesg log (to be found in the /var/log directory).

You are only using radeon.agpmode=-1 in those logs. You need to also use video=ofonly.
Ron Mitchell (rm2892) wrote : | #18 |
I did try that, but got only a blank screen. Couldn't even get into CLI <ctn-alt-F1>.
Does it matter which arguement comes first?
Ron Mitchell (rm2892) wrote : | #19 |
here's my /var/log/Xorg.0.log for a case where I used the 2 commands:
video=ofonly radeon.agpmode=-1
It produces a blank screen and from there I'm unable to do <cntl-alt-F1> or anything else.
Sorry for the delay in reply. I've been on the sick list for the past few days, and yesterday it really got bad. Flu or something. When I don't feel like going near the fridge or the computer, I know it's not good.

Ron, there is nothing obviously wrong in that Xorg.0.log. To be honest I'm a bit confused with what is working and what isn't. According to your comments here https:/
Ron Mitchell (rm2892) wrote : | #22 |
Ok, let me see if I can get this straight:
Using builds from September 13th
1) The live ISO - burned to a DVD-RW boots the desktop with distorted (8 bit) colours on some of the buttons and title bars.
2) If I attempt to install from the live CD, I get the blank dialog box headed "Install". Unable to proceed from there
3) The Alternate install disk also burned to a DVD-RW completed the installation successfully, but when I booted from that, it resulted in a blank screen with a cursor in the centre which appeared to have the same graphics distortions; ie coloured horizontal bars at one small square in the centre of the screen. I could move the cursor and sometimes the colour distortions would disappear, but then come back as I moved the cursor about. Was unable to get anything else except the distorted cursor. I could however jump to a CLI by doing <ctl-alt-f1).
4) Booted as in (3) but with command <video=ofonly> I got a blank screen and was unable to proceed anywhere from there.
Clear as mud?

I can't reproduce your problem with an installed system from a live CD (13/9/2012 with video=ofonly radeon.agpmode=-1 boot parameters) .... are you able to confirm this is an 'alternate' only problem?
Ron Mitchell (rm2892) wrote : | #24 |
It was the live cd installed system.
I'm going to download both again tonight and try it all again. Hopefully I should then be able to report based on current builds.
Seems like mine is the only eMac on the planet that won't accept the normal yaboot commands.

There are problems with both iso's, both the live CD and the alternate.
The live CD produces the blank dialogue boxes which make an install impossible. The alternate will install ok, but produces an installation with a blank screen and except for the cursor.
When I first started testing in early August, these problems were not happening.

I have a G4 iBook. I've installed fine with the alternate tonight. I used 'install video=ofonly'.
I think possibly KMS is picking a poor modeline for you and your signal is going out of range for your monitor. Hence black screen. Otherwise it is your card (see the kernel release notes about the radeon 9200). It doesn't really explain why the live/desktop CD brings you to a working 8 bit desktop and the alternate doesn't though......

Makes sense. Could be just my eMac. If nobody else is having the problem, then it need not concern you further.
I'm trying another experiment here. Setting up QEMU one of my other boxes that has Ubuntu Studio on it. Will see what happens there.
Very much appreciate your help, and I will have a look at the kernel release notes.

I can confirm your problem with the alternate install! When I turn off KMS I get the blank screen except the screwed up mouse pointer. I'll look into it. This didn't happen with the live/desktop ISO install.

ojordan (ojordan12345) wrote : | #29 |
Right, this is essentially bug 1040526 . Lightdm (the login manager) can't cope with the 8 bit pseudo colour and completely screws up its display. Once you log in (by just typing your password) the display is okay (all be it in 8 bit).
For the live/desktop ISO install I had selected to login automatically and this is why I wasn't seeing the problem on that install.
Workaround is to increase the colour depth via an xorg.conf (as you say):
Section "Screen"
Identifier "Screen0"
DefaultDepth 24
EndSection
Or turn on KMS. If KMS is not selecting an appropriate modeline then you should be able to define your own like you've done before, but called the mode "800x600" instead of "800x600_60.00". It'll probably want to put you into "1024x768" so make sure you define a modeline for that.

@Ron please ignore the comments I made about modelines in post 29. The 10-monitor.conf you have in post 16 should work under KMS too.
