[Bug 22976] Re: Live CD boots to a black screen on Blueberry G3 iMac
This bug report seems to have devolved into an amalgam of different issues, and the upstreamed bug report is closed as invalid due to being not a driver problem but rather xorg.conf problems.

Here are the /var/log/Xorg.0.log file from the Lucid release desktop cdrom and the minimal xorg.conf file to work around the bug. A curious (but probably unrelated) observation is that using Driver fbdev in xorg.conf gives a grainy looking screen (seems like 8-bit depth) while Option UseFBDev true gives the correct colors. ** Attachment added: Xorg.0.log from Lucid release desktop cdrom. http://launchpadlibrarian.net/48369606/Xorg.0.log.cdrom -- Live CD boots to a black screen on Blueberry G3 iMac https://bugs.launchpad.net/bugs/22976 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 22976] Re: Live CD boots to a black screen on Blueberry G3 iMac
It would be nice if you could try Ubuntu 8.04 LTS development version's live CD and see if this problem is finally fixed. For example the current one is at: http://cdimage.ubuntu.com/ports/daily-live/20080310 /hardy-desktop-powerpc.iso The link will be gone in a few days, after that the latest one can be found in subdirectories of http://cdimage.ubuntu.com/ports/daily-live/ Ubuntu 8.04 has a new 6.8.0 version of xserver-xorg-video-ati, which has a very large number of bug fixes etc. -- Live CD boots to a black screen on Blueberry G3 iMac https://bugs.launchpad.net/bugs/22976 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Tested using your 20080310 download link - same problem. The bootup process looks like: 1. The brown desktop background flashes up for a second or so 2. The screen then blanks and I get the text boot options 3. After a while, screen turns white for a few seconds then goes black again 4. A text cursor can be seen flashing in the top-left of the screen That's it - nothing else happens.

[Bug 22976] Re: Live CD boots to a black screen on Blueberry G3 iMac
I have to retract my previous post. I did manage to destroy one and a half CRT iMacs but it was not at all Ubuntu-related. The good folks at FreeGeek confirmed for me that they never see these problems. What explains my explosions I think is the accumulation of dust on a coil related to the CRT. The dust causes the coil to conduct where it should not, and it heats up and eventually shorts out. I saved the second iMac by opening it up and thoroughly dusting it out with an air duster. It now runs without any overheating or display glitches.

[Bug 22976] Re: Live CD boots to a black screen on Blueberry G3 iMac
I was having the problems described above installing Edubuntu Edgy on some of my wife's school's older G3 iMacs (400-500MHz, 256MB RAM). Note that with 128MB of RAM, these machines were basically useless (256MB and they're usable). I managed to work around the problem described above as follows: - Boot the Edubuntu 6.10 Edgy LiveCD - At the boot prompt, specify single user mode with the single kernel option boot: live single - Once the machine comes up to a shell, Change the following in /etc/X11/xorg.conf (patch attached) HorizSync 60-60 VertRefresh 75-117 and DefaultDepth 15 - startx After that, I was able to run the live distro, and successfully perform an installation. Note that at this point, you're running X as root, which is generally not preferred). Following the installation, the xorg.conf changes were preserved, which was nice. However, the additional kernel boot parameter single was also preserved. So after the installation completed, the machine rebooted again into single-user mode where I had to remove the single kernel boot option and reinstall yaboot via ybin. # sed -i s/single// /etc/yaboot.conf # ybin --verbose # reboot After that, my installation worked fine. To the Ubuntu developers... The proper monitor ranges should be detectable from ddcprobe at boot time on these machines, so I'd think you ought to be able to populate the HorizSync and VertRefresh properly in the next Fiesty ISOs. As for the DefaultDepth... This might ultimately be a problem with X for not failing back to a lower, working color depth. But for the sake of Fiesty ISOs booting on G3 iMacs (plenty still hanging around our school systems at least), any chance you could detect them, and special case their DefaultDepth down to 15bit?

[Bug 22976] Re: Live CD boots to a black screen on Blueberry G3 iMac
As far as I can tell from my recent experiences the black screen means that the ATI r128 drivers uses the VGA output instead of the builtin CRT. I speculate that this is a PC inheritance. The VGA output is well hidden under a hatch at the back, on my 400 MHz grape iMac DV at least, so I attached a VGA screen there. The X output nicelly appeared on the VGA screen only.The framebuffer driver used before X is up outputs console on both outputs.

ok, tried on all my old CRT iMacs.
