Wayland Screen Flicker Bug

WetGeek We indeed live in interesting times.

And one more thing that started working now, that hadn't been working recently. That's the night-light feature. My eyes are sensitive to bright light ever since I had cataract surgery. And when I worked at a computer when it's dark outside, and I opened up a Vivaldi session, it was painful. But night-light is obviously working now, and it's much better on the eyes.

I'm updating the Latitude laptop with Xfce on it now. This is what DoFlicky looks like when it has that upgrade for Nvidia:

Since I have no interest in playing legacy Windows games, I passed on the 32-bit option, but others may want that as well.

This is the dependency I mentioned earlier. After this, the upgrade will be installed. This is where I saw Wayland mentioned. I'm a little confused about whether the flickering was actually an Intel or NVidia issue, but I can't argue with the results.

Authentication is needed, but a convenient dialog lets you do that from here. When the upgrade is finished, a restart is needed.

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

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

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.

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!

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 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.

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

BuzzPCSOS It just usually after 3-4 years should be replaced.
