View Full Version : [ubuntu] Even safe graphics mode failed

I tried to set up my Lucid with dual monitors. I have done this successfully with several past versions of Ubuntu, but apparently everything I have learned is wrong.

I made a backup of xorg.conf and added Xinerama and the other configuration items I needed. X failed to load. Then I copied my backup to xorg.conf and...X failed to load. Then I tried booting up in safe graphics made, and X failed to load. I tried dpkg-reconfigure xserver-xorg, but it did nothing. Literally nothing -- no error, no output, no nothing. Then I saw someone who had suggested to apt-get remove --purge xserver-xorg, then reinstall it, and X failed to load.

I am at a complete loss. I have now read that the dpkg-reconfigure xserver-xorg is no longer used, that the os is supposed to autodetect everything now, but in that case I don't see how I will ever get dual monitors.

In any case, I can live without dual monitors, but I need at least ONE monitor, and I have no idea how to get the configuration working. Any help would be appreciated.

This forum is hopeless!

The person above has had no reply in 4 weeks, and guess what! now I've got the same problem and there's no answer.

The fault has occurred (in my case) because I've had to replace the motherboard, which has a different graphics chip. Unfortunately, re-installing Karmic is not an option - unless there is a way without the live CD formatting the drive?
