I am stil having the same issue as https://community.parrotsec.org/t/hdmi-output-not-working/5250 despite I have done everything said in the guide. I have downloaded i915 driver and rebooted but still neither I could start in normal mode nor it recognized HDMI output. HDMI works fine on WIndows. It looks like the issue is closed without a solution but I am still having it. Waiting for your suggestions. Thanks for your time.
