What happens if you purge all of nouveau and NVidia drivers, leaving Xorg to
use its integral modesetting driver?
Thanks for the suggestion. I wasn't hopeful, having tried removing the
intel driver (with an old i915 chip) in *this* box running SL7, but
dmesg | grep segfault gives 7 lines:
sddm[xx]: segfault at 0 ip xxxx sp xxxx error 4 in libQT5Core.so.5.6.1[xxx]
or similar but with error 14 in sddm.
dnf history shows that 58 packages were updated on 10 Oct, but that
would be with yumex-dnf and I can't find where it stores its history for
I had previously tried the nvidia build from scrpms, which didn't
install cleanly (rpm -i --force) but also pointed to libQT5Core.so.5.6.1
