Timo thank you very much!

The 1.1.7 build has made its way into impish already:

   https://packages.ubuntu.com/impish/libnvidia-egl-wayland1

   Package: libnvidia-egl-wayland1 (1:1.1.7-1) [universe]
   amd64 arm64 armhf ppc64el s390x

However, since libnvidia-gl:

   # currently available 465
   https://packages.ubuntu.com/impish/libnvidia-gl-465

   # experimental build of 470
   <https://launchpad.net/~albertomilone/+archive/ubuntu/nvidia-testing/+sourcepub/12507185/+listing-archive-extra 
 >

both provide "amd64 i386" but the libnvidia-egl-wayland1 impish
package lacks an i386 build, the i386 version of the libnvidia-gl
drivers will be crippled when it comes to wayland performance when
running 32-bit only graphics apps (i.e. games) on a 64-bit system.

Of course, anyone so affected can just grab the 1.1.7 egl-wayland
i386 .deb directly from:

   http://ftp.debian.org/debian/pool/main/e/egl-wayland/

But it would be nice to get the ubuntu libnvidia-egl-wayland1
universe package updated to include i386 so that's not necessary.

Any idea how to make that happen?

I have cc'd this message to the universe maintainers list just in case.

Thanks,

Kyle McKay
