spent all day yesterday installing and reinstalling ubuntu studio and kde so i could set up a work environment i want. xfce works fine (ish) with my monitor setup but kde has proved useless.
i wanted to set up kde because xfce put all of my desktop icons on a monitor i dedicate to video playback, making them useless as they are always behind video images. i thought kde would let me position them where i wanted in the desktop space (on my lower right monitor). not so. i have four monitors. the first is a 65 inch 4k monitor up on my wall and is dedicated to running video. the remaining three are in a row below the 4k. i have things (at least in windows, osx, and xfce) set up to represent this physical layout with the 4k above and the others side by side below. when i log in to a plasma session, though, i get nothing but empty screens with a cursor. i've read quite a number of posts around the inter-tubes about similar issues with kde. none of the suggested remedies has worked for me. alt + f2, alt + space, alt + anything, r-click. nothing does anything. i simply have a powerful system designed, apparently, to let me wiggle a mouse cursor but not do anything else. very frustrating. in years past i have used kde and liked it a lot but in this system and context it's proved useless. i've tried off-and-on for over fifteen years to get a smoothe setup for editing video and audio on linux and have found ubuntu studio and xfce to nearly have gotten me there finally. in the past it was always the difficulty in getting multiple monitors to set up correctly without having to spend all of my time on it (only takes a couple of minutes in other oses). in linux this has never been possible for me. i was hoping things had finally gotten there. xfce has come close but has some pretty serious workarounds that are necessary. i was hoping that kde would solve those and decided that i'd live with the extra weight of kde over xfce since i thought it would likely solve those last nagging issues about placement of desktop icons. very frustrating to spend a full day on it only to find that it's actually got worse problems than xfce, not to mention that the issues seems to have been reoccurring for some years. just wanted to put this down here so the experience would be noted. hope it gets fixed someday. i'll check back again in a few years. thanks, babag |

Same for me. I installed fresh KDE 5.13.5 on OpenSUSE Tumbleweed. I have a dual monitor setup with a VEGA 64 on opensource driver. For once I found that multi-monitor configuration worked well.
But I have the same problem, except I have a desktop on fresh boot as it log in my account directly. When I log out or if the screen turns off, I get a dark-gray screen and ctrl+alt+F1 doesn't move to terminal. I have to reboot, but sshd was working. Where do I look for log files to understand what happens ? I don't see anything particular in Xorg.0.log.old. EDIT : I changed render backend to XRender and still the same. |

i cannot be of any help for your specific problems, but hop in to say: its not all lost. I am on a three monitor setup with Nvidia drivers, Kde Neon, and it is working without problems. clickclack - works, thx4zat

I disabled power saving for turning the screen off and it seems like fixed.
I got some kernel traces as it may be related to amdgpu ? babag, what videocard are you on ? As for my hardware : MSI Vega 64 Asus X399 Prime Threadripper 1900X uname -a :
lspci |grep VGA :
hwinfo :
dmesg | grep amdgpu :
I think I will install kubuntu and check if it has the same problem, when I have the time. Here are my traces in /var/log/messages
