[14:16] <skullboy> Hi guys
[14:16] <skullboy> i've a particular issue with my xubuntu
[14:17] <skullboy> i've installed a 18.04 on my toshiba laptop
[14:17] <skullboy> usually i use it with two external monitor
[14:17] <skullboy> HDMI and VGA
[14:18] <skullboy> if i launch a video on youtube (for example)
[14:18] <skullboy> the monitor connected via HDMI go blank for some second
[14:19] <skullboy> and come back
[14:22] <brainwash> skullboy: is that behavior specific to a certain web browser?
[14:26] <skullboy> no
[14:26] <skullboy> maybe an audio to HDMI issue?
[14:28] <brainwash> no idea
[14:29] <brainwash> I would test with a different web browser, with parole and a local video file, etc.
[14:30] <brainwash> also, look through the Xorg log files in /var/log
[14:31] <skullboy> i'm downloading a sample video to do the test with parole
[14:34] <skullboy> mmmm with chromium all it's fine
[14:35] <brainwash> and you use firefox otherwise?
[14:35] <skullboy> yes
[14:35] <skullboy> also with parole
[14:36] <skullboy> all work fine
[14:36] <skullboy> it's a firefox issue
[14:36] <brainwash> it could be that firefox has a different method of preventing monitors entering sleep mode while it plays a video
[14:37] <brainwash> in your case this method is not working 100% properly
[14:39] <brainwash> did you check if the external monitor blanks again when pausing and then resuming the youtube video?
[14:53] <skullboy> with pause the issue disappear
[15:00] <skullboy> ok, disable hardware acceleration in FF solve the problem
[15:02] <skullboy> 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] <visone> howdy
[17:03] <skullboy> exit
