[systemd-devel] xorg uses 100% CPU after upgrading to 226

[Jin Liu]

After upgrading to 226, the Xorg process keeps using 100% CPU. Also, the
"xrandr --dpi 168" command in my .xinitrc no longer works.

My startx.service and .xinitrc:

$ systemctl cat startx.service
# /etc/systemd/system/startx.service
[Unit]
Description=Direct X login
After=systemd-user-sessions.service
Conflicts=getty at tty1.service

[Service]
User=jin
TTYPath=/dev/tty1
PAMName=login
Environment=DISPLAY=:0
ExecStart=/usr/bin/bash --login -c "cd; (/usr/lib/xorg-server/Xorg
-nolisten tcp vt1 &); source .xinitrc"

[Install]
WantedBy=graphical.target
$ cat .xinitrc
#!/bin/sh

#

# ~/.xinitrc

#

# Executed by startx (run your window manager from here)

export DESKTOP_SESSION="plasma"

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

xrandr --dpi 168

exec /usr/bin/startkde

$

BTW, if I move the "xrandr --dpi 168" line into /usr/bin/startkde, it works
again (only DPI setting. Xorg still uses 100% CPU).

What change in version 226 could cause the above problem, and how should I
change the above files to fix it? Thanks.

Regards,

Jin Liu
