Hey, Guys. This is my first question in this forum. I am a newbie of Linux. I am using debian for one month.
Yesterday Evening, I install a software called zgv which used to view image. After run it in tty1, the resolution changed. and i remove the zgv.
Today, when i start debian. before log in gnome. i can swtich to tty1 well by ctrl + atl + f1. But after i log in gnome. when i use ctrl+atl+f1, the screen is black without nothing(text, prompt).
At first, i think maybe the tty is broken.But When I tried these action:
#type root password
then the system shutdown.
so the tty is working well, but i can't seen.
please help me make my tty display well.
