Hello all,

After last (monthly) emerge world update the following things happened.
First is that KDE, which i am using, does not show any menu panel/bar at the bottom of the screen. I can not start any help by clicking at the black background with any mouse button.
Another problem is that there is no background wallpaper on the screen.
I am running gentoo for years. Last 10 years i am emerge world monthly.
dmesg does not give any errors, no errors are in the /var/log/Xorg.0.log .

However when the system sleeps after it is inactive for 15 minutes in my case, the computer gives me "The screen locker is broken and unlocking is not possible anymore.
In order to unlock switch to a virtual terminal (e.g. Ctrl+Alt+F2), log in and execute the command:"
After i do Ctrl+Alt+F2 i go to console with the programs i started running which i see by: pr -u username .

Also i noticed that dmesg gives me:
Code:
[ 1724.324386] kscreenlocker_g[11985]: segfault at 10 ip 00007f7ea43ece88 sp 00007ffe14b37c60 error 4 in libQt5Core.so.5.12.3[7f7ea4333000+28c000]


I was trying to reinstall kscreenlocker and dev-qt/qtcore but that did not help.
I am still getting no menu panel/bar in KDE.

Here is what i have:
emerge --info

I read somewhere that i should enable MenuBar in .config directory files. I did not do this yet, plus this is just a MenuBar, i had wallpaper and screenlocker issues. I thought they should be connected.

Did anybody look at this topic?

It looks like startkde is conflicting with KDE menu panel. The menu panel is not starting.

Thank you to those who followed on this problem i described. This problem is resolved by itself, likely due to some bug present in the plasma somewhere earlier.
Anyways, i kept updating the world monthly. Today i also recompiled the kernel 4.19.72 and (1) i got the background back and (2) the computer goes to the hibernating stage and comes back as it did before....
