    Thanks for the replies and assistance. Please excuse me if I have overlooked something in my work to creating a solution while I implement the information shared in the post provided.

    So far, this is where I am at now after implementing the above recommendations (it has improved but not fully).

    While in XFCE, since it was the only DE that would respond for me, I was able to open Yast Software Management to help in the removal of the package: xf86-video-nouveau. This method was successful. Following this step, I wasn't sure if the system needed a restart so I moved forward with doing that procedure as a thought it might be required.

    Upon logging back in, I noticed the experience with both DE's (XFCE and KDE) were the same as before without any improvement. To make sure I followed the correct understanding, I opened Yast Software Management again to verify that this package had been removed (xf86-video-nouveau) and it showed as no longer an active system package. While in there, I did a full search on nouveau and noticed that the 3D piece was active, so I went ahead and removed that since I remember hearing it could create issues with systems.

    Seeing that the change of system desktop experience hadn't changed, I moved forward with the next suggestion of ~/.cache/ & rm -rf * the full contents within the directory. Following the previous system activation change, I did a simple sudo init 6 and let the system restart with the changes.

    Positive side, this did make a vast improvement with XFCE but KDE is still very odd with sizing issues and the right screen still persist with a shaking experience.

    I'm looking into possible further solutions but nothing more positive to report to you all just yet.

    Thanks again and I hope to further this discussion with some positive improvements on my part. We'll see by tomorrow, I hope lol
    Reads like some progress. Please the output from

    Thinking about your comments re image shaking...
    From there, my left screen was reaching into my right screen. Too, my right screen started to have a sort of rapid and slight space vibration to anything on that screen. I started to pull things over just to check and windows were fine in the left monitor but shaking in the right. While they were not shaking in the left monitor, the two did share something similar: they each had really huge icons and task bars.

    ...FWIW, here's a similar thread where turning off and on the compositor was tried, and changing HDMI cables to no avail.
    https://forum.kde.org/viewtopic.php?f=309&t=165294

    The OP there found that changing the refresh rate (via xrandr) helped. Display mode changes can be done on the fly, and if found to work can be added to an "autostart" script (or other similar approach) to make the desired changes persistent. YMMV.

    Good evening,

    Thanks to both of you for sticking with me and helping me progress this further.

    Just to report before I provide the outputs requested: XFCE is still stable on the next day but, sadly, yes, KDE Plasma is still having the expanded screen issues and shaking on the right monitor. To help with the outputs provided below, the right monitor is assigned as - Display 2 and I believe that in the xrandr this means it is HDMI 2.

    Here is the outputs requested (xrandr first):

    Thanks for supplying that info. If you swap the monitor connections, does the fault move with the change? Do the monitors have more than one HDMI input available to try? Are the monitor settings identical?

    FWIW, here's a recent Manjaro thread where a slight vertical shake was observed...one user reported changing the refresh rate and back again was enough to resolve the issue. It could be a subtle timing issue.

    The "*+ " indicates use of native display specifications, for you in my estimation making software less suspect than hardware. First thing to try is switching cables between the two displays. Does the corruption stay with the display, or move with the cable? Stay with display explains itself - display problem. Stays with cable could be an NVidia problem, or a cable problem, or a software problem.

    Boot to any live KDE or XFCE media and the problem remains reproducible suggests likely hardware trouble.

    In Plasma you could try disabling compositing to lessen graphics load.

    Unhappy Re: KDE Plasma (*) Display Complications

    deano_ferrari & mrmazda,

    While I wanted to come at this subject and attempt the provided ideas you both have shared, I apologize but i won't be able to attempt them until tomorrow due to work needs.

    I do community based IT-Security presentations and had an audio problem with my OpenSUSE Laptop that had to be resolved which distracted me the entire night before the presentation and after

    However, I didn't want to be disrespectful by not replying to your messages. I am planning to return to the suggestions and start on them asap tomorrow. Thanks again for each of your time and patience with me.

    I hope you each have a great day and next day!

    All good. We're all volunteers. People help when they can, and you can reply when you have free time.

    Good evening deano_ferrari,

    Thanks for understanding, and thanks for your volunteer activities here in this community. My goal is to learn so having such a friendly volunteer team of community members patiently open to helping me achieve that goal is very appreciative. (I too am a heavy volunteer; holding three different lead positions in my community at home. )

    I have some positive updates for this thread and I think it's ready to be closed! (BOOM! )

    Here are the issues that were raised with this thread and how we have come to resolve them thanks to the help received here:

    Issue: Night Color would quit
    Resolution: While uncertain as to a long term solution, I am starting to think that this is related to KDE caching. During periods of me going into Display Configurations, the Night Color will return to it being no longer aware it was in use even though it was activated. The temporary solution to this is doing a simple restart or sudo init 6. Upon return, the Night Color is active again.
    • Creating a Test user account, I found that this Night Color removal if going into Display Configuration happens too.


    Issue: KDE is completely broken and unable to log into Plasma DE session
    • This was when it was broken in KDE and then later bled into XFCE

    Solution: I believe the solution here was related to the cleaning of the ~/.cache (rm -rf ~/.cache)
    • My assumption for this solution is based on the memory of my attempt to solve the Night Color issue, I played around a lot with the Nigh Color activation options over and over again. I believe this likely caused some kind of configuration editing issue that caused the full system to be confused later on.
      • I'm not confident enough in my awareness of Linux to be certain on this. My assumption is based on reaction changes after I ran the cache clearing and then did a sudo init 6.

    Issue: Right screen is hazy/shaky
    Resolution: Complete! Attempting the recommended further solutions were easy to do and helped me better understand more fault areas on my system. However, the issue still persisted and only in KDE Plasma. It wasn't until I opened up Display Configurations to look at what could possibly be different with the two monitors... (palms face - I'm embarrassed with myself)
    • Checking the two monitors more closely, I saw the issue: refresh rate. *palms face*
      • While I believe you both helped with this suggestion before, I clearly did not do enough thorough review. The left monitor is 75Hz while the right was set at 30Hz. Equaling them out, the shaky/hazy look changed - immediately.

    Thoughts: I believe I must have changed the refresh rate when the caching issue occurred not realizing I made the refresh rate change and also accepted the change.


    Thanks for the help on this!

    This has been a really fun activity for me; so, thanks to you each for helping me troubleshoot and learn a TON throughout the whole process. While I am sure it had some stressful moments for me, this was really fun all around.

    Lesson I have learned from this is that I am going to keep this lab first layer pretty stable (no more playing around) and instead I am going to enable a KVM system to start doing my curious tinkering. Also, I am going to be reading the full OpenSUSE documentation that is provided as well as get myself a copy of the UNIX and Linux System Administration Handbook 5th Edition.

    I hope you each the best going forward and I look forward to being more active in this community.
