x42-meter freeze my machines with nvidia driver

[PhilippePloquin]

Hello,
x42meter plugins crash fairly quickly on my two machines having in common the nvidia drivers. Everything goes well when I test these plugins on "non-nvidia" machines.

Distribution: debian stretch, kernel 4.9.0.3 rt, nvidia-legacy-304-xx driver, modules tested : the whole series of x42-meters, in standalone or in plugin with ardour. version 0.9.3 ( debian stretch ) or the latest 0.9.14 demo , same results.

The plugin tested is alone. Playing with the plugin window quickly leads to a blocking of the whole machine, mandatory reboot.

Thanks for all your work on linux and ardour, and for your help

So far this has only been an issue with the nouvau driver (all openGL plugins fail, the driver only works with single window GL applications).

However you're the first to report an issue with the nvidia binary driver. Can you update to the latest nvidia driver?

Do other openGL plugins work? (e.g. harrison XT-* or overtoneDSP or zam-audio, or other x42-plugins)

I can't use the latest nvidia driver because my old dell precision M6700 laptop only accepts this old version of the drivers.

Playing with Zam multi comp or x42-eq freeze the machine.
It's ok with eq10q, or calf equalizer ...

I'm sorry to say that there's nothing I can do about it, then.
You need a system with a working openGL setup to use those plugins.

Thank you for your quick response. I will look on the opengl side ...

I will look on the opengl side ...

That's probably a good idea. Most modern plugins rely on it (also all DPF based ones: dragonfly-reverb, wolf-shaper, etc etc)
