I have been searching for days on getting started with Linux and still can't get started.
I am running the following
CAELinux xunbuntu 12.04 I7 16 GB ram SSD 500 gb Nvidia GT 540M and an integrated graphics card.
I tried to follow the information from this link
sudo apt-get purge nvidia sudo add-apt-repository ppa:graphics-drivers sudo apt-get update
the following shows up. I don't know if this matters.
Note the .com was removed because I can W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://download.opensuse.org ./ Release: The following signatures were invalid: KEYEXPIRED 1396321314
then when I try to download the driver....
sudo apt-get install nvidia-352 Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package nvidia-352
At this point I tried the manual method from the same site.
but when I typed in
sudo service lightdm stop
I got a
"starting the virtual box Guest additions Fail!" "modprode vboxguest failed"
and if I tried to type in my user name and hit enter what I typed just showed up in white text and enter did nothing.
Any help would be greatly appreciated. I have already reinstalled CAELinux xubuntu 12.04 four times to start fresh.
When I tried to allow the root user access to the X server:
And point the command to the right DISPLAY:
sudo DISPLAY=$DISPLAY gedit /etc/profile
this was diplayed
gedit: command not found
sudo apt-get update && sudo apt-get install nvidia-352
and after all the update info it displayed
Unable to locate package nvidia-352
