Hi, I've Gigabyte Radeon RX Vega 64 and sometimes when booting it doesn't give any signal to monitor over DisplayPort. Rebooting usually helps and it works fine after. Not sure if it's hardware or software issue. In dmesg only suspicious thing I see is many [drm] perform_link_training_with_retries: Link training attempt 3 of 4 failed Any ideas? Also is there some way to force reload/turn on signal so I don't need to reboot?
