Package: src:linux-grsec
Version: 4.9.18-1+grsec201703261106+1
Severity: important
Dear Maintainer,
Recently I installed grsec kernel for my PC which is running Debian 9 with KDE
Plasma as the main desktop environment. It would have been good if sddm had
started so I can login to KDE but grsec seems to be preventing sddm from
starting up (some kind of "denied priority change" and "untrusted exec"). Every
time the boot process finishes, I'm greeted with a totally blank screen.
Attempted to run "startx" and what I got is just the KDE mouse cursor and
nothing else. Trying to run "sddm" would throw a "...resource overstep" error.
I'm just a noob, please help me :(
Update : Just used "paxctl -m" to disable some sort of protection on
/usr/bin/plasmashell as well as sddm and nothing came up to my expectation.
