Unfortunately both this build and the -301 that followed it completely hosed my system, in what seems to be an incompatibility with the Nvidia binary drivers (rpmfusion 410.xx series). I initially thought it was the update to xorg-x11-drv-nvidia-410.78-1.fc29.x86_64 that caused the problem, but after downgrading to 410.66 and still encountering it, I was forced to go back to 4.18.17-300.fc29.x86_64 (with nvidia 410.78, so that update's definitely not the problem in and of itself).

Startup goes fine at first, but at some point during my session login a null pointer dereference in the kernel drm code is logged. After that point, the system gives the appearance of working but really it's toast. Firefox sits in the process table but never displays anything at all, gThumb dumps core, Chrome opens up literally empty windows (not even the client side decorations), and if I try to shut the machine down it completely freezes and requires a 4-second lean on the power button to switch it off.

Here's the kernel oops as logged to the journal:

Looking at ifas' comment, the previous means that I need to update xapps from updates-testing. So it sounds like nemo-4.0.1 should really Requires: xapps >= 1.4, due to the symbol present in xapps-1.4.1-1.fc29, that isn't in libxapp.so.1 from xapps-1.2.2-1.fc29?

After updating nemo and nemo-extensions (only), running nemo-desktop results in:

nemo-desktop: symbol lookup error: nemo-desktop: undefined symbol: xapp_icon_chooser_dialog_get_type

Installed as a dependency of rpmfusion's latest mpv-libs update, appears to be largely unproblematic.

BZ#1535355 qt-creator 4.0.5-2 has wrong dependency on qbs

I solved the conflict (in my "anonymous" comment above) by performing a two-stage update: dnf upgrade --best --allowerasing forced the uninstall of qt-creator-4.5.0-1.fc27 in order to update everything else. Then a manual dnf install qt-creator downgraded qbs from 1.10.0 to 1.9.0 to successfully install qt-creator-4.5.0-2.fc27. Odd that dnf couldn't automatically solve this on its own, though.

karma

Success! \o/
