WetGeek That's what happened to me when I tried that a while ago. Apparently it's Plank for the GNOME machines, and Latte for the KDE machines. For a while, I was using Plank everywhere, but as I've just written, that ended today.

We indeed live in interesting times.

it's funny for Latte, I did the menu launch, nothing. I do the terminal launch it says Latte already running but nothing for eyeballs to see...I had to file an XFCE Plank bug at dev tracker today---again the parallel irony with Latte---it wouldn't show dots for the minimized apps....until I lowered refresh rate which I thought was weird.

that needs to be made clear somewhere🙂. I dragged 50 k-packages into XFCE for nothing.

like you I never have a negative reaction. it's funny quite often, needs to be noted, and very much a great adventure. too bad about the Lions and I don't like the Chiefs and my teams not in it anyway so I digress 😎

        I just finished upgrading the Xfce laptop and restarting, and as one might expect, there were some differences. Unlike on the Plasma laptop, there was no problem running Plank either before or after the upgrade. So I'm less convinced that the upgrade had anything to do with Plank. I think it was this weekend's update that did that instead. While it was up and running, it stayed that way, but once it was shut down, it wouldn't start again.

        brent I dragged 50 k-packages into XFCE for nothing.

        I haven't tried that, but I wouldn't expect it to be a problem. I've used other KDE applications in every GNOME-based computer and VM I've ever created, without any problems. I figured the Plank/Latte issue was a one-off.

            WetGeek . I figured the Plank/Latte issue was a one-off.

            thanks for confirming this. I figured an anomaly but needed a 2nd opinion

              My Latitude HD graphics card still flickers here :-(
              I checked for an updated graphics driver but DoFlicky said there were none there which figures because I only have Intel HD Graphics 620 and no extra NVIDIA card.
              I searched for the egl-wayland dependency in the Software Centre that @WetGeek mentioned, it is not installed on my laptop and I'm not going to try installing it on a hunch that it might make things better.
              I will continue to run in wayland as the flicker is not that bad and it only takes a small mouse movement to stop it. I can see that there are Exciting Times ahead for all of us on Solus and maybe a future update will end the flicker for good.

                BuzzPCSOS maybe a future update will end the flicker for good.

                I'm hoping so as well. Now that the cause and the cure are known, it's time to get it fixed for everyone who's affected.

                And now that I'm working with it more, I'm seeing that it's not entirely cured on my latitude, either. But now it's almost unnoticeable, as you wrote, and stops the flickering itself when I just keep using the mouse. It used to be a violent shaking of the image that made me think something was about to break, I'd need to move the mouse pretty far away to stop it.

                Plus, the other changes I mentioned are very welcome. Night color working again, for instance. It's not yet dawn here, and my eyes appreciate that it automatically changed. And the night color icon now stays visible in the system tray and can be toggled on and off. Before, not only did that icon not do anything, but it jumped back into the hidden icons secetion if I clicked on it.

                    WetGeek Just need to share this. I took a serious look at my display tonight. Compositor settings, Resolution, Refresh rate, RGB Range, Legacy Applications preferences, everything! I also spent a while watching a video by Chris Titus called Fix Screen Tearing in Linux. To be honest I did not follow any of his advice except to run xrandr to show the capabilities of my video card. Turns out that my refresh rate tops out at about 58.8Hz. I also noticed that in System Settings - Display Configuration is set to 60hz. On a whim I lowered it to 40Hz and applied the change.
                    So far so good!
                    I can't make my screen flicker anymore in Wayland. I have spent several minutes trying to find the sweet spot where the screen flickers and it seems to have gone :-))
                    Is it just me? Please let me know. Could it really be that simple?

                        BuzzPCSOS Is it just me? Please let me know. Could it really be that simple?

                        I'll give that a try and see if it gets rid of what little flickering I still see. Thanks for the idea!

                            BuzzPCSOS I am in same boat with firefox as you guys are with wayland made it
                            about non existent but still burps now and then.

                            glxgears is cool just to see your framerate.

                            I got say tho the gentoo site is really good for help on stuff laid out really well easy to understand
                            but havent had alot time to look at it more.
                            There stuff seems pretty proper and right.
                            Will look at your suggestion since I dont do games.

                              WetGeek I'll give that a try

                              I'm not sure I'm going to call this a cure already, but it's certainly looking good here. I've been trying to prompt some flickering for the last 15 minutes or so, and haven't seen a single flicker at 48 Hz.

                              Keep in mind that silent films were shot and displayed at 16 Hz, as that was proven to be fast enough for users to perceive it as smooth movement instead of individual frames. Later, that standard was changed to 24 Hz, but it was because doing that increased the audio range of the optical sound track on "talkies." And 48 Hz is twice that speed, so it's clearly fast enough for all but the gamers.

                              I'm going to keep it at 48 Hz for a while now (at least until the flickering is demonstrably fixed), and I'll address this later, when I've had enough time to be sure. Thanks for doing the research to uncover this apparent fix.

                                  WetGeek I'm just glad it wasn't just me that it worked for. Not a glamorous patch but it will do for now.

                                    WetGeek I have some possible news regarding this issue.

                                    Aw, fsck. It tuns out that my early experience with this turned out not to be true. Apparently my sesion had been on X11 - though I'd thought it was on Wayland - when I saw that apparent improvement with the mini toolbar setting turned back on. I apologize if anyone was inconvenienced by my comment. I truly thought the problem had been solved.

                                    I discovered my mistake today when I turned that setting back on for the rest of my VMs, and found that they still lock up under the circumstances I've mentioned. My first thought was that it must be DE specific, 'cause it was a Plasma VM where I thought the problem had been solved. But no. I re-checked a Plasma VM, and it also locked up the computer under the same circumstances. So the only likely reason for my confusion is that I was actually in an X11 session when I believed I was using Wayland. Sorry about that.

                                        WetGeek Thought it was too good to be true, further experimentation indicates that the screen position where flicker occurs is slightly further up the screen when a lower refresh rate is used which is why I did not find it last night.
                                        Sorry to get your hopes up.
                                        Investigation continues :-(

                                          Well I have fixed my screen issues in firefox have it running now with hardware support and plays videos
                                          without issues. (will see if the fix holds)
                                          Dunno why on this lenovo it became an issue all of a sudden.
                                          I needed to learn more about video...lol (yuck)
                                          Think I am going rebase the cpu/gpu glue later prob could use it.....Rofl

                                            Axios I wonder what CPU you are running. Certainly worth getting some new thermal paste on the GPU/CPU and maybe looking at how much RAM you have installed as web browsers tend to eat lots.

                                                BuzzPCSOS It just usually after 3-4 years should be replaced.
                                                Intel(R) Pentium(R) CPU 4405U @ 2.10GHz

                                                    Axios

                                                    Axios A low(ish) power CPU with a troublesome graphics card is not a good combination. I try to keep intel i3 as my minimum spec for a 'keeper'.
                                                    The X11 graphics fix should work ok for everything except for Wayland on that machine, we will just have to wait for the Wayland fix.
                                                    The flickering you experienced is only in the Firefox?
                                                    That could just be because it is the environment where the cursor does the most milage.
                                                    When I was testing I ended up marking the point on my screen with a masking tape pointer so that I could relocate the place that caused the flickering quickly with different programs running.
                                                    Changing the refresh frequency certainly changes the characteristics of the flicker but does not remove it.
                                                    I wonder if the problem is just an outdated graphics driver built into the kernel, mine is listed as i915. Frankly out of my depth at that point but it still interests me that the contents of the X11 fix file did not need details of specific patches, only an identifier as "Intel-Graphics" and a driver as "intel". Seems like there are a few parts here that are not joining the dots.

                                                          BuzzPCSOS Welllll my experience with the .conf files is alot the info the syntax is wrong
                                                          people dont do their research before coming out with these command web pages..

                                                          Did couple times on desktop but firefox was the main issue.

                                                          Driver is (Iris) or (intel) depending what file and Gen you are working with not i915 is the gpu
                                                          This page is good for the intel graphic gens https://wiki.gentoo.org/wiki/Intel.
                                                          Some of the current newer stuff the kernel handles it mostly.

                                                          The skinny of Had use 2 files 20-intel.conf and 20-modesettings.conf and by testing and tuning
                                                          the settings in both tend to interact somewhat sometimes.
                                                          Syntax and commands different for each.

                                                          The files in etc/x11/xorg.conf.d overide the ones in usr/share/x11/xorg.conf.d
                                                          gotta watch that I deleted them in second and put them in the first.

                                                          I had a thread I started but got no reply so deleted Found online that the modestting was good for both
                                                          x11 and wayland wanted to know if that was correct or not.
                                                          (So if thats the case may be an avenue for wayland)

                                                          When I went to software cursor cured most but had fine tune and add couple things in both files .But I see that
                                                          wayland I think already uses software cursor. (From what I c online people complaining issues with that dunno)

                                                          Hope didnt confuse and maybe something in there that gets you thinking.
                                                          But your understanding appears on course with from what I learned My first time really dealing with this in
                                                          deep detail.

                                                          My biggest thought that 20-intel.conf and 20-modestting.conf would mess with each other and load one or the other but appears not the case

                                                          It was a journey
                                                          Note: The above is of course for X but might give some understanding in the case of wayland and I know
                                                          they are two different animals.

                                                          Just tested again it was consistent failures before ---Everything appears still working.---YA

                                                              Axios Thanks for your thoughts and insights. Wayland being so new - there is not much chatter on how to patch unwanted behaviour. Looking around there are plenty of threads dealing with the same flicker on Microsoft OSs so at least we are not the only ones. ;-)

                                                                  BuzzPCSOS I made mouse flicker good and blank screen and what ever else you wanted with 20-Modesetting.conf then I added the 20-intel.conf and it stopped then fine tuned abit.
                                                                  So go figure....lol

                                                                  (But not 100% sure) two step process
