Cannot watch youtube in fullscreen mode

Question

When I am watching videos on youtube and toggle the screen to full screen or switch back from full screen to normal mode, the video stops and sometimes stops loading or starts loading from the start again. I installed ubuntu-restricted-extras so I have flash installed.

Solution

There's a fix posted here. It seems to have done the trick for me, but I'm not 100% sure it's the same problem for you. This is a problem with Flash and its hardware acceleration, not YouTube itself.

In case the above site is unavailable, here's the fix:

sudo mkdir /etc/adobe
echo "OverrideGPUValidation = 1" | sudo tee -a /etc/adobe/mms.cfg
