pE: can't load wlan_xauth.ko: Operation not permitted (as root, probably some subroutine in permanent use? Is it a toggle at the startup services?) but it was good compilation training, svn up had some changes in the main files, so it was not a mistake upgrading to r351552M now. Fixed my Plasma5 and I added Enlightment as a DM. For my grafic card there's the drm-legacy-kmod-driver the best and this works, too now - but compositor's still on XRender as the most common problem is to loose the insights of the windows after some minutes with OpenGL (2 and 3.1). Any ideas except /dev/null the whole stuff from the beginnning on? btw, 'pkg: gstreamer1-plugins-lame has a missing dependency: lame' ... does this happen to everyone when using pkg install ? there's no dependency lame and lame means something like 'like a horse that's gone lame.' but freeBSD isn't, just read UPDATING! Gonna build some old darwin kernel now, the influence of BSD is magnificant in comparison to the mach-part - but that's another chapter. tomorrow, Miranda On Tue, 27 Aug 2019 at 15:03, Maksim Yevmenkin <maksim.yevmenkin@gmail.com> wrote: > > > Hmm... interesting.... > > > > > > I only took a brief look at it.
