This is more informational than a question. For the last month or more I have had problems with screen blanking every 10 minutes and sound not starting for maybe 30 seconds when a video is played. Pausing a video would delay the sound once it got going. I had Dolphin open once a good month ago just deleting files from my download folder. Right click, delete, one file at a time. After a dozen or so files the screen went blank for a second or 2, back on, off for 3, on for 10, off for 1 etc. Just random. I did my searching, adjusted every setting I could find, tried different combos and still the problem was there. So I started paying attention to the apps I had open for a pattern. It came down to Dolphin, Firefox, VLC, and Kaffeine I had open prior to screen blanking. Well, I quit using VLC about 10 days ago and have had 0 problems since. I know VLC has an advanced button for preferences and I think I tried anything obvious. Didn't help. Whenever I opened and used VLC and then closed it it seemed to affect system settings. And it wasn't limited to screen blanking at 10 minutes. I also had a video playing once and blank time was 30 seconds, and another at 4 seconds. VLC also does not want to run a playlist in order(for me anyway). I found a checkbox in the advanced settings titled something like 'play files randomly forever' and thought AH HA, problem solved. I unchecked it, clicked save, closed the app and reopend it. Tried playing a DVD again and it is still random. Checked the settings and that particular box is checked again. I could not uncheck it and get it to stick. I don't know people. I kinda don't care now. I just don't use VLC any more. Kaffeine works fine.
Has anyone seen similar effects?
