MPlayer cannot do full screen in my freshly installed Debian Jessie on Ace Aspire E5-551G-T16Q laptop that has AMD Radeon R7 series graphics. Here is the output from lshw -short -C display:

H/W path         Device      Class          Description
=======================================================
/0/100/1                     display        Kaveri [Radeon R6 Graphics]
/0/100/2.1/0                 display        Opal XT [Radeon R7 M265]

While it is possible to play video files in mplayer, it is not possible to see fullscreen. Here are the possibly interesting lines of mplayer output during startup:

Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file:

Debian Jessie installation was pretty straightforward. I did not perform any Xorg config and do not have /etc/X11/xorg.conf. Installing nvidia-vdpau-driver that brings libvdpau_nvidia.so (in the error above) does not help. Any suggestion will be greatly appreciated.

EDIT: Output from dpkg -l | grep glx:

ii  libgl1-mesa-glx:amd64                 10.3.2-1+deb8u1                      amd64        free implementation of the OpenGL API -- GLX runtime

I just reinstalled Debian and continue to face the same problem making me believe that it is not due to something that I've done.

  • What GLX packages do you have installed? dpkg -l | grep glx to start with, perhaps. – Faheem Mitha Jan 31 '16 at 18:10

I have been able to get mplayer to play in full screen by installing proprietary drivers gtom AMD as per instructions: here.

I had tried this earlier having installed Jessie for the first time but had to undo the step after rebooting to a non-GUI screen (textual login screen only). I reckon this was due to installing the nvidia-vdpau-driver package that apparently breaks the sanity of the system. Hope this saves the time of others.

EDIT: Even if one does not wish to use mplayer there is noticeable screen flicker while scrolling web pages when the open source driver is used. So, the proprietary driver might have to be used anyway.
