Hi Lina, so you are mainly playing with a server and you are certnaily used an external monitor.
Have you tried with a totally different monitor ?
Are using a VGA terminal or Xorg windows ?
What does dmesg gives against nouveau ?
As root:
# dmesg | grep -i nouveau
What is you actual kernel:
# uname -a
Best whises,
Jerome
