Crashes in Totem if xserver-xorg-video-intel is not installed

[Doug McMahon]

Test Case on Intel gpu:
Install gstreamer1.0-vaapi
Remove (purge) xserver-xorg-video-intel
Reboot
Open totem & or try to play an AVC video with totem

What happens:
$ totem
libva info: VA-API version 0.39.2
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_39
libva info: va_openDriver() returns 0
intel_do_flush_locked failed: No such file or directory

Then totem crashes.

If xserver-xorg-video-intel is re-installed & a reboot then totem works fine & uses hwdec on supported files. Same output as above but no "intel_do_flush_locked failed: No such file or directory"

So if confirm-able then possibly xserver-xorg-video-intel should be a depend of gstreamer1.0-vaapi unless some other solution.

In regards to Yakkety -
gst-vappi crashes totem all the time, i.e. with or without the xserver package, same output about intel_do_flush_locked failed.
Are you all using DRI3 in yakkety?? (dri3info seems to indicate yes though xorg log doesn't..

[Timo Aaltonen (tjaalton)]

I think this is because the modesetting X driver is missing DRI2 page flip support, which just got added to xserver git master.

Yakkety xserver is patched to use modesetting instead of intel, so in order to use intel you need an xorg.conf.

surely fixed by now
