Comment # 46 on bug 1126480 from Josua Mayer

I was making a tarball from the output of rpm -q --list - passing the output to
xrags, then tar.
I think it is time for a massive facepalm, because: the tarball is missing
lotso f modules, including nouveau.ko.

After the leaves had settled I did a
cp -r /.snapshots/218/snapshot/lib/modules/4.12.14-lp151.25-default
/lib/modules/
cp /.snapshots/218/snapshot/boot/vmlinuz-4.12.14-lp151.25-default /boot/
dracut -f --kver 4.12.14-lp151.25-default
Rebooted, and all good.

rpm -r /.snapshots/218/snapshot -qf /boot/vmlinuz-4.12.14-lp151.25-default
kernel-default-4.12.14-lp151.25.4.x86_64

Meanwhile on the latest 15.1 version in the repos:
kernel-default-4.12.14-lp151.26.4.x86_64
the glxinfo test succeeds; and even Minecraft is playable with DRI_PRIME=1 and
the nouveau driver!


That means we were hunting a ghost between 25.3 and 25.4 (snapshots 217 and
218) :(
I should take a break now till I remember the proper use of tar.
Also, I don't know where the ghost went. Cold versus warm boot? Do I need to
power it off for a while? Who knows.
I will not touch the current system, and just turn it back on tomorrow to see
if it still works.
