libice and graphics issue XFCE
I had not updated since 2019-07-15 so many packages were upgraded today. The boot went to a black screen but later the desktop appeared after a longer than usual delay. The bottom of the XFCE terminal is a broken white line, and the window icons to maximise and minimise are wrong, if you hover on them they change. Trying the fallback initramfs made no difference. There were no errors in syslog but Xorg.0.log had an error I had not seen before:
[ 11.545] (II) systemd-logind: took control of session /org/freedesktop/login1/session/_31
[ 11.546] (II) xfree86: Adding drm device (/dev/dri/card0)
[ 11.546] (II) systemd-logind: got fd for /dev/dri/card0 226:0 fd 10 paused 1
[ 11.546] (EE) Error systemd-logind returned paused fd for drm node
[ 11.546] (II) systemd-logind: releasing fd for 226:0
Downgrading the kernel did not fix it.
