I have an Nvidia card and two monitors.

Every time I log in to Unity on Ubuntu 11.10, I get this error:

x monitor error

"Could not apply the stored configuration for monitors"

I have tried opening nvidia-settings, but none of my experimental alterations to any of the settings has made a difference.

I can still use my computer, but it seems to break the themes, icons, and styles so my computer looks like Unix circa 1992, which is a pretty annoying.

How do I kill this error?

This should fix it:

rm $HOME/.config/monitors.xml
  • For some reason, I don't even have the .config direcotory/and monitors.xml file. I still have this problem still. If I click OK, everything goes and works exactly as planned and all the normal visuals are back. i still want to get rid of that annoying popup though

  • you will need a directory .config regardless

  • Had this problem in Linux Mint and Ubuntu using a VM, now working after deleting this conf file :)

  • Can I prevent this file from being created automatically? It's rather annoying to have to delete it every time.
