It is an nxcomp patch that needs to be applied in the nx-libs-lite _and_ the nx-libs-full tarball release. - * Add 401_nxcomp_big-requests.full+lite.patch. Support usage of the - BIG-REQUESTS X11 extension on the server-side. (See Debian bug #766299). * debian/libnx-x11.postinst: + Don't use dpkg-architecture (bin:package dpkg-dev) in postinst script. Instead prep a libnx-x11.postinst script at build time.
