Most of the users have been getting Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set in Linux environment while checking requirement the oracle installations on  Linux 5.2 or later versions. I have tried plenty of options but finally, i have fixed this issue through one Linux commands. The  error screenshot desc belows

Steps to resolve this issue:

1) login into root user( su -l root)

2) execute this command : xhost +SI:localuser:oracle

3) login to the oracle user

4) execute ./runInstaller

Now, its working fine.
