I am running Ubuntu 9.04, with an nVidia card and the 180 drivers through Ubuntu's menu.
I also have this issue where the mouse pointer stays on one screen even when moved to another screen. I have followed the instructions provided in this thread from https://launchpad.net/~m0sia/+archive/ppa however, I am receiving the following messages when I run sudo apt-get update.
Reading package lists... Done
W: GPG error: http://ppa.launchpad.net jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8D09D5BE298D57CC
W: You may want to run apt-get update to correct these problems
If someone is able to assist with this problem, it would be really appreciated and if I do get that far, then, when in the next step it is stated 'You're now ready to install software from the PPA!', is this just a case of entering 'sudo apt-get install' in the Terminal window and pressing Enter?
