[14:26] no [14:26] maybe an audio to HDMI issue? [14:28] no idea [14:29] I would test with a different web browser, with parole and a local video file, etc. [14:30] also, look through the Xorg log files in /var/log [14:31] i'm downloading a sample video to do the test with parole [14:34] mmmm with chromium all it's fine [14:35] and you use firefox otherwise? [14:35] yes [14:35] also with parole [14:36] all work fine [14:36] it's a firefox issue [14:36] it could be that firefox has a different method of preventing monitors entering sleep mode while it plays a video [14:37] in your case this method is not working 100% properly [14:39] did you check if the external monitor blanks again when pausing and then resuming the youtube video? [14:53] with pause the issue disappear [15:00] ok, disable hardware acceleration in FF solve the problem [15:02] in firefox under preference -> performance must remove the flag from Use recommended performance settings and now it's possible uncheck Use hardware acceleration when available [15:03] howdy [17:03] exit
