HI, Intel technician,
when I ran 2017 intel advisor XE under Linux, the following error occurred
09:08:24: Error: Unable to initialize GTK+, is DISPLAY set properly?
could you do me a favour and give me an advise to fix above problem?
Thanks in advance and I am looking forward to hearing from you.
Do you have your X environment setup? The error message mentions DISPLAY needing to be set.
Try launching an xterm from your terminal and see if that works.
