crash of DE during Ring call

Affects: Ring GNU/Linux GNOME client (since 20180625 ?)

Original messages: Ring-dev, Mastodon

It was reported by several users from ring-dev and Mastodon that making a video call leads the desktop environment (KDE and GNOME) to crash (possibly because of an X11 issue).

It was supposed that the bug is coming from xorg-nouveau, but some Radeon users seem to be also affected by this bug.

Notice [AVHWDeviceContext @ 0x7fa39400bac0] Failed to initialise VAAPI connection: -1 (unknown libva error). Looks like a bug on libva's side.

Have you installed the mesa vaapi drivers? Could you paste the Ring AVLOGLEVEL=40? What is the output of vainfo?

sudo apt-get install mesa-va-drivers on Debian 9

Let me know if you need more info.

mesa-va-drivers is already the newest version (13.0.6-1+b2).
mesa-va-drivers set to manually installed.

libva info: VA-API version 0.39.4
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
vaInitialize failed with error code -1 (unknown libva error),exit

forwarded from Mastodon

OK, looks like mesa-va-drivers is installed.

Seeing your lsmod grep, I can't see the mesa-va-driver loaded, could you post a full lsmod ? Otherwise, the output with grep mesa, grep r600 and grep drv ? If the driver isn't loaded it is normal that libva va_getDriverName() fails.

Also, can you take a look at your /var/log/kern.log ? If the driver is failing to load or something like that, you should be able to get some info from there.

Thanks !
