After booting , the screen displays the message:
red ha tlinux (8.0) Psyche
Then the screen just turns black & blank.
Then again it shows the above message.In the intermediate time,I try to login as root ,but to no avail.(KB works fine)
It continues to toggle in this way.
All i had done was that the last time,i had given the command reboot from the console.After shutting down,some display settings of the monitor had come on the screen and vanished.
Thats it ,apart from that i havent changed anything.
