[SOLVED] SDDM booting to black screen

startx works fine on TTY2 after login.

~/.xinitrc:

#!/bin/sh

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap

# merge in defaults and keymaps

if [ -f $sysresources ]; then







    xrdb -merge $sysresources

fi

if [ -f $sysmodmap ]; then
    xmodmap $sysmodmap
fi

if [ -f "$userresources" ]; then







    xrdb -merge "$userresources"

fi

if [ -f "$usermodmap" ]; then
    xmodmap "$usermodmap"
fi

# start some nice programs

if [ -d /etc/X11/xinit/xinitrc.d ] ; then
 for f in /etc/X11/xinit/xinitrc.d/?*.sh ; do
  [ -x "$f" ] && . "$f"
 done
 unset f
fi

exec startkde

I've tried uninstalling sddm and reinstalling it along with sddm-kcm but it just continues to boot to a black screen.

When I disable (via systemctl) sddm, my TTY1 shows:

Starting version 242.84-2-arch
/dev/nvme0n1p2: clean, 275991/29130752 files, 4514142/116506880 blocks
_

The underscore has been blinking on TTY1 since last night.

Re: [SOLVED] SDDM booting to black screen

Which hardware?

In general this does read like the early boot entropy issue, try hammering random buttons, if that helps and lscpu | grep rdrand gives you output add 

random.trust_cpu=on

to your kernel parameters, otherwise install and enable haveged

Re: [SOLVED] SDDM booting to black screen

Just tried hammering on keyboard and editing kernel params. Also tried haveged. nothing works.

Re: [SOLVED] SDDM booting to black screen

Please boot the system using live media,  chroot in and post the journal from the last stuck boot.

Re: [SOLVED] SDDM booting to black screen

It's not a stuck boot. I just have to go to TTY2, login, and startx. I've already posted the journal.

Re: [SOLVED] SDDM booting to black screen

You did not post the journal nor information about the hardware, post your journal and information on the hardware you are trying this on. Other alternatives, though we have insufficient data on whether you properly enabled haveged or edited the kernel parameters, would be an issue with early modesetting, but we could clear most doubts with an actual log
