this happens after installing easyubuntu and letting it install codecs and other stuff.
after rebooting, this happens....it can't seem to start the X server anymore

i fixed this anyway. luckily easyubuntu created a backup before installing any codecs. it was then fairly easy to replace the backup file with the one that caused that error!

I had a similar problem when I was setting up the machine I'm using right now.

The problem is probably NOT the codecs, but instead it's the NVIDIA driver that you selected when you were installing EasyUbuntu. Try again, but this time leave UNCHECKED the video drivers when you are selecting the packages for EasyUbuntu to install.

Which NVIDIA driver you need depends on which card you have. If your video card is working good enough for you now, then you probably don't need to mess with it. But if you want the very-best, gee-whiz, ain't-that-cool, I-gotta-play-that-game out of your card, you need to figure out which NVIDIA video driver is best for your card. But that's the subject of a whole 'nother discussion.

Happy Trails,

I'm getting the same error message. How did you solve it?

Thanks

"How did you solve it?"

1. Log into the system at the console, using your username and password.
2. Become root:
     yourname@yoursystem:~# sudo -s
You will be prompted for a password; type YOUR password. Assuming you are a sudoer and you typed in everything correctly, you will be at a root prompt, which will look something like the following:
     root@yoursystem:~#
3. Reconfigure the xserver:
     root@yoursystem:~# dpkg-reconfigure xserver-xorg
4. Answer the questions that are asked. Usually, it's best to let the system auto-detect your gear, because it usually knows better than you do. (Or at least it knows better than I do.)
5. When the questions are all done, you'll be back at the root prompt. Unless you have a compelling reason not to, it's a good practice to reboot now.
     root@yoursystem:~# reboot now

If you still have problems, you might have to do it again, but tell the system what driver to use. You'll need to do a little research to find out which Xserver driver is best for your video card. You can find out what card you have by asking the system to list the pci devices:
     root@yoursystem:~# lspci
If you add the "-v" flag after lspci, you will get a very detailed and long output. Consequently, if you want more detail, pipe the output to less:
     root@yoursystem:~# lspci -v | less

That's what worked for me.

Good Luck,

Loye Young
