I am using kubuntu on a Thinkpad W510 with a Quadro FX 880M display adapter. I can install 12.04 from the CD, no problem. But when I did sudo apt-get dist-upgrade, I ended up with a black screen. I tried several troubleshooting steps I found on the web, all to no avail.
When I would do X -configure, I would get this:
(++) Using config file: "/root/xorg.conf.new"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
Number of created screens does not match number of detected devices.
ddxSigGiveUp: Closing log
Server terminated with error (2). Closing log file.
So I started over, and installed all over again from the 12.04 CD.
I am afraid to do sudo apt-get dist-upgrade.
What should I do? Thanks
