Nice one! Installed all updates. Reboot. Log into KDE. Get black screen with mouse cursor. Lol. Love your work guys ;)
Comment 1 David Edmundson 2018-02-22 18:26:17 UTC
Try to keep things constructive.

X or wayland? Also please tell us which distro?

Does this happen for a new user?


Can you access krunner with alt+f2 
if so can you spawn plasmashell from there and report on any output.

Failing that, can you from a TTY look at ~/.local/share/sddm/xorg-session.log and report if there's anything relevant there.
Comment 2 David Edmundson 2018-02-22 18:27:48 UTC
If it's Neon dev edition. It's a known downstream issue.
Comment 3 whizzzkid 2018-02-23 02:17:49 UTC
Can confirm, ran an update and logged into a black screen with the mouse cursor.
Comment 4 Christoph Feck 2018-02-23 02:22:11 UTC
Please do not change the status unless you did provide the information requested in comment #1.
Comment 5 whizzzkid 2018-02-23 02:31:52 UTC
X or wayland?
X11

Also please tell us which distro?
KDE neon developer edition, 16.04, xenial

Does this happen for a new user?
not sure

Can you access krunner with alt+f2
yes
 
if so can you spawn plasmashell from there and report on any output.
no visible output

Failing that, can you from a TTY look at ~/.local/share/sddm/xorg-session.log and report if there's anything relevant there.
that log is empty.

Basically I can log in fine, after login I get black screen with the cursor. I can start the konsole (alt+ctrl+T) and start the browser (google-chrome-stable) and it seem to work fine. The network is connected fine over ethernet, wifi fails.
Comment 6 Christoph Feck 2018-02-23 03:22:16 UTC
Then you are seeing bug 390919 (pending Qt update; still needs to rebuild all packages).

Let's wait for the information from the original reporter.

Hi Hi, 

I was on KDE Plasma Neon 5.12.1 using this repository: 
deb http://archive.neon.kde.org/release xenial main

I am running a fully updated Ubuntu 16.04. I was notified in the notification area of updates that was ready to download and install. I selected to update all. 
When this was done, I was prompted for more updates, I updated all. When this was done I rebooted for good measure. Got to the KDE login screen. Logged in and got the black screen with a mouse cursor.

I tried to move .config .local .cache .kde to a backup folder. Tried again same thing. 

dpkg -l | grep -i mesa shows

My /var/log/Xorg.0.log is attached

I do not know about alt+f2 :(

The only way I managed to get my system back was 

sudo apt-get purge kde-* neon-* plasma-*
then 
sudo apt-get install plasma-desktop

If you need more information let me know
