I just reinstalled fedora 20 after that I have installed cuda and was not able to start fedora. Now the problem is that I have two screens, but only the one connected to the vga port works. Both works perfectly in windows, so the problem is not the cable itself. It is the dvi-port which does not work.

When I installed fedora the first time, there was no problem so I don't know why it doesn't work now.

lspci -nnk | grep -iA2 vga

 rpm -qa nvidia

gives nothing.

rpm -ql nvidia says
package nvidia not installed

I am using the integrated graphic card, not the tesla since it has only one port.

Hi, did you check your connections? Did you update your drivers?

We will need additional info in order to help. Please open a terminal and issue these commands (one at time). lspci -nnk | grep -iA2 vga - xrandr . Then edit your question and add the results.

@cydrobolt Yes, I have checked my connections, and it wouldn't work in windows if that was the problem. How can I update the drivers? Do I need to go to Intels homepage and look for my IGD or can I use the yum somehow?

@NikTh Was this how you wanted it?

xrandr is a separate command @Eric Bylow

I "solved" it by making a complete re-installation of Fedora. I also switched the Tesla for a GeForce, but it worked on the integrated graphic card before, so I guess the re-installation was the important thing.
