I have an old HP laptop with non-working display. So i decided to convert the laptop to a private server. I connected it to my TV and installed Debian 7.7. The installation was smooth with the display coming on my TV. But after installing and trying to boot into Debian I am able to see only GRUB menu and after selecting the OS the display is gone. I think it is switched to monitor display.
Any idea how this can be fixed?
