I've recently installed Ubuntu 12.04 on some friend machine. He's migrating from Windows XP, and i'm his guide.

Right now he's having a problem with some youtube videos.


All the videos from that yt user seems to have the same trouble. Problem is, when going to full screen, my friend sees this:


So i try the video here, on my job's PC, were also have Ubuntu 12.04, and see it fine.

I ask him about the browser. Google Chrome. Ask him then to try Firefox, and says that in Firefox it works fine. I'm on Firefox too.

When i try the video on Chrome here on my job, i do see it ok in fullscreen, BUT, i notice that Chrome takes a few seconds to actually maximize it. That is, it's costly for Chrome to go fullcreen. Then try another video from another youtube user in Chrome, and it goes fullscreen fine.

So, something's wrong with those videos. As i go everywhere installing Ubuntu, and have no idea of what is going on here, i would like to learn what is happening here.

My friend has a nVidia GEForce 9800 GT with 319 drivers. I have an old legacy ATI here on my job.

Any clue?

  • Had a look, it could be just the quality of the video is too high for that computer (HD 720p / 1080p). Try another HD video like this to see if that is just the problem. Most Youtube videos are not HD, so might not present any problems. Also, update his computer using apt-get or something.

  • Hi wilf. I don't think it's quality. As said, he has a decen gpu with latest drivers and, as you can see, he plays heavy games with it. Also, everything's up to date: installed Ubuntu two days ago, and apt-upgrade'd the full system this very morning. Oct 31, 2013 at 18:53
  • No, but I find that Chrome is pretty useless with HD flash videos - like you said in the question, takes ages to fullscreen etc. I alos prefer Firefox for that sort of thing, one reason being that I can use this extension much better than in Chrome. Besides, I find that the integrated Intel graphics works much better for just using Flash and the Internet. Happy Halloween.

  • Well, that's interesting. However, i've checked it out in this machine (my job) and the video with hard-time-maximizing in chrome is in 320. No HD involved. Oct 31, 2013 at 19:25
  • That seems more an issue about flash/pepperflash + nvidia + nvidia drivers. He should try to install privative drivers (or rollback to free ones). In such cases is just keep trying until you find the correct one. Please, add the output of sudo lspci -nnk | grep -A7 VGA of the system that has problems.

Finally, i've solved this.

I have no idea yet what's so special about those videos. However, by trial and error, i tested on my friend's machine some other screen resolutions, and saw that the one he was using was the only one with this problem. That resolution was 1360x768.

So, searching about problems with that resolution, i've found a bizarre problem regarding that resolution, some standars, and nvidia. It seems that is a bogus resolution, and there's a problem between 1360x768 and 1366x768. nVidia gpus seems to detect 1360 but no 1366. So, i went to nvidia settings (not Ubuntu control center), and setted the resolution by hand at 1366 using "advanced" option in the resolution configuration. After that, the video displays fine on my friend's machine.

Odd stuff.


Im working with Adobe Flash Player Version and test it in fullscreen and Its seems works fine! May be He needs change and upgrade his version. Could you tellme about Flash Player embed version in Chrome? You can know about it, just right click in video in somewhere.

Take care.

  • I'm asking my friend, he'll respond when online again. But my version here (my job) is 11.9.900.117. As said, the video here plays ok, but it has some strange lag when going fullscreen that other videos don't. Guess it's gotta be some odd video spec. Oct 31, 2013 at 19:29

if you have trouble with youtube videos, try html5 player.

bottom of youtube page. html5 player in beta ( experiment) link.

  • Thanks for the tip. But tried the html5 test and yt just doesn't load the video with the video tag, it shows the same old flash player. Guess that video don't have html5 (firefox) compatible versions. Oct 31, 2013 at 19:46
  • when you activated it do not use back button. search same video again. if you use back button. test will be cancelled
