can't log in due to DISPLAY variable issues
can't log in due to DISPLAY variable issues
yesterday, I used vpn in a laptop to connect my computer A
I wanted to open firefox on computer A through shell but it prompted "“Error: no display specified"
then I used
Code:export DISPLAY=":0.0"
and it was fine then
later I wanted to use VNC for connection, and I used display 3 for the VNC server.
anyway, the remote operation is OK
today I come to the computer A, and I noticed that I can't open firefox
it prompts
"“Error: no display specified"
I tried to export DISPLAY to different values, it doesn't work
then I reboot the computer, then there is the login interface which requires me to input my username and password. I input the correct username/password, but I can't log in
how can I deal with this? thanks!

What distribution+version of Linux are you running? Also, which version of Xorg? I have never seen this problem before, so more information would be helpful in sorting this out.
Sometimes, real fast is almost as good as real time.
