All, This might just be a silly issue or something bigger. I'm trying to test GTKwave for some verilog tests, and I'm running into an issue where GTKwave is not being intialized. Error issue: Could not initialize GTK! Is DISPLAY env var/xhost set? Alas, my .profile has: export DISPLAY=:0.0 I can't figure out how to get rid of this error! Any help is most welcomed and thanked!
