blank screen from Xserver - eMac G4 1.25GHz ppc

[professordes]

Binary package hint: xserver-xorg-video-ati

On upgrading to Gutsy RC from Feisty, X gives a blank screen on an eMac G4 1.25Ghz. There are no obvious error messages
in Xorg.0.log. Is this similar to the Mac Mini issue for the gutsy ati driver (which I also got bitten by) and is there a ConnectorTable or MacModel option in xorg.conf that will sort this out?

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.

[Tormod Volden (tormodvolden)]

Please also try the newest driver from https://wiki.ubuntu.com/XorgOnTheEdge

[professordes (d-a-johnston)]

The (non-working) xorg.conf is attached. Removing xorg.conf completely drops you back to the text Xserver not started screen when X attempts to start.

[professordes (d-a-johnston)]

This is the Xorg.0.log when the xorg.conf is present

[professordes (d-a-johnston)]

This is lspci -v for the machine in question

[professordes (d-a-johnston)]

Last and least - this is Xorg.0.log again when xorg.conf is removed.

[professordes (d-a-johnston)]

The prebuilt drivers at https://wiki.ubuntu.com/XorgOnTheEdge are all for i386 rather than ppc?

[Tormod Volden (tormodvolden)]

Thanks for the log files. Yes, sorry, the prebuilt drivers are i386. I overlooked that you had a G4.

There is the ConnectorTable option you can play with, see bug 141372 for more information.

[professordes (d-a-johnston)]

I built the driver from upstream, but with similar results - still a blank screen. I'll try the ConnectorTable options and see if something works.

[Jim Carroll (mrmaple)]

I'm having the same problem on a mac mini G4.

I tried adding Options MacModel mini, and downgradig to xserver-xorg-video-ati_6.6.3-2_powerpc.deb
without any luck. (Gutsy had xserver-xorg-video-ati 1:6.7.195-1ubuntu2)

I also tried
        Option ConnectorTable "4,1,1,1,0,1,2,1"

without any luck.

[Tormod Volden (tormodvolden)]

Please file separate bugs for mac mini issues. The mac mini should be automatically detected (and use correct ConnectorTable) in the newest driver.

Please see https://wiki.ubuntu.com/XorgOnTheEdge for how to get xserver-xorg-video-ati-dbg_6.7.195+git20071020tv.dsc and build it yourself on powerpc.

[professordes (d-a-johnston)]

Downgrading to xserver-xorg-video-ati_6.6.3-2_powerpc.deb _does_ get things (i.e. X) working again on the emac.

No luck with ConnectorTable options on the Gutsy module (does anyone know the correct incantations for an emac with these?), nor with
a self-built 6.7.195-2 module from upstream.

[Jade Sailor (jsailor)]

Same problem here (1.25 gHz eMac, black screen, xorg.conf tweaking (refresh/sync rates, ConnectorTable, MacModel, disabling modules) didn't fix it, and downgrading to 6.6.3-2 did.)

[Bryce Harrington (bryce)]

Please check if this issue still exists with the latest Hardy 8.04.1 and/or Intrepid.

[Roger Binns (ubuntu-rogerbinns)]

My PowerPC Mac Mini always got blank screens with livecds. 8.04.1 however has finally fixed that.

[Bryce Harrington (bryce)]

Closing as fixed as per comment #15, and no one saying otherwise.

[Risto Suominen (risto-suominen)]

Still present on eMac 1.25. Tested with 8.04.1 desktop CD.

[Bryce Harrington (bryce)]

Risto, please file a new bug. You may be seeing something different than the others since they found their issue was fixed.
