Fixing blue tint in youtube videos

Ever since some time in late March, my Youtube videos have been blue.  I put up with it, figuring that once I upgraded to Kubuntu 12.04 (which I did this evening), everything would be fixed.  …nope.  So then I decided to use the Googler and figure out what to do.

Apparently it’s caused by a bug in the latest update for flash and Adobe is not being quick to correct it (we all know how long it took for them to acknowledge 64 bit computers).  But anyway, I did the following:

1)  I created a new adobe directory under etc

sudo mkdir /etc/adobe

2)  I then modified the Flash configuration by the following line of code that I blindly pasted into my terminal because the internetz told me to.  (I figured if it turned out we don’t want nOverrideGPUValidation, whetever the hell that is, to be true we could just delete the directory and hope everything goes back to normal)

echo -e "EnableLinuxHWVideoDecode=1\nOverrideGPUValidation=true" | sudo tee /etc/adobe/mms.cfg > /dev/null

Anyway, much to my delight, it worked.  Here’s the source of the info: http://askubuntu.com/questions/117127/flash-video-appears-blue

Manual nvidia drivers install

So I ran into this problem after re-installing Kubuntu 10.04 (for reasons that I shall not go into ::rolls eyes::).  Anyway, having an Nvidia GeForce 8400GS, I figured I could use the standard autodetection that Ubuntu provides for proprietary graphics drivers (described here) but for some reason that was not the case, so I needed to go in manually.

  • First, using the terminal, I installed the latest nvidia drivers

sudo apt-get install nvidia-current

  • Then, I restarted my computer and realized that my resolution was all wonky.  When I went into my “nvidia x server settings,” it told me that no such drivers were enabled.
  • so I followed the directions in the error message and ran the following command:

sudo nvidia-xconfig

  • Then I restarted my x server with the command 

sudo restart kdm

NOTE: the “kdm” is only because I’m running KDE.  If you’re running gnome it’s “gdm” and after 11.10 it’s “lightdm”

  • then everything worked fine!
