I have a horrible conundrum. My lousy HP zBook 17 laptop has built in Intel graphics as well as an Nvidia Quadro card and no ability in the BIOS to shut down the Intel card. This causes a garbled screen on login and forces me to close the lid after logging in to make it sleep, then when it awakens all is good. Or at least was until today. I am using Zorin Core with XFCE. Now it will only work when I go to the Zorin Desktop (Gnome?).
Does anyone have any idea how I can get back to using XFCE? I really like the speediness and features of that desktop environment.
