Fed up. Random lockups are back with a vengeance.

[DoYouKubuntu]

It's too soon to say anything definitive, but in the 48 hours since losing QtCurve, not a single lockup. Keep in mind that, as my title said, they were back with a vengeance, so 48 hours is quite a long time--compared to freezing up multiple times a day.

[DoYouKubuntu]

Did anyone think QtCurve could've been the culprit? Especially since there were long blocks of time with no lockups, and QtC was always running.

But now, lockup-free since losing QtC, I'm looking at two possibilities: pure coincidence that the lockups stopped as soon as I dumped QtC, or it was the culprit all along.

[GreyGeek]

TIme will tell. Looking forward to a month of bug free operation!

[DoYouKubuntu]

Indeed, GG. I left EVERYTHING running when I put the laptop to bed last night. Got up this morning, and it's fine.

If it turns out to be QtCurve, I'll want to know why/what part of it. Like is there a specific element that--when some unknown-to-me event happens--clashes and locks it up? The problem with that is QtC has at least a zillion options. Stepping through them one-by-one to hone in on the bug could take years...

[GreyGeek]

It seems that the Theme that was default when I installed 20.04 is Breeze.qtcurve !
But, my system is and has been stable as a rock.

Four days and counting. I'm still kind of shaking my head in disbelief, because I just never thought QtCurve could be the problem. And no one else did either.

GG, my QtC is very highly customized. It took years to get it just the way I wanted. Some of its features, though, no longer work (on 20.04)--as documented somewhere around here! So now I'm wondering if it's...not exactly deprecated, but something on that spectrum, like on its way out, or works but not really, or...something. You're not having issues, I am. Was. Might. Whatever!

[jlittle]

I'm a QtCurve devotee from wayback too. I've never had plasma problems attributable to QtCurve, and in the early days of plasma I had lots of problems...

Would you like to export your QtCurve settings and post them here?

Yes! And so much more. I love the fine, FINE tuning QtCurve allows, like choosing your own symbol for obfuscating passwords--I like the good old asterisk! Visually, for my tastes, QtC is by far the most beautiful style.

[jlittle]

I posted the result of system settings, application style, click "configure settings" on the QtCurve choice, export. If you are not importing your QtCurve settings, but just copying them into .local/share/QtCurve, conceivably some validation by using "import" might help.

However, comparing your choices with mine, most of them are different, but not in any startling way. I can't set the titlebarButtonColors; the settings sub-window for them is unresponsive. I imagine the "window decorations" theme sets them.

In KDE plasma these days there's complicated interactions between the colour scheme, application style, window decorations, and the compositor. I get quite confused and frustrated, and bash away changing this and that till I get something acceptable. It doesn't help that I find the KDE default Breeze themes and anything gnomish awful. However, plasma theming gets less buggy with every release, and the various download settings options have amazing choices. (I wish the plasma widgets had a similar wealth of choices.)

So your hangs are provoked by some complex interaction between lots of things. My guess would be kwin, because when plasmashell fails the raw windows still work, including the X root window. (In the early days of plasma the combination of kwin and the nVidia driver for my on-board graphics caused lots of hangs, and sometimes I could get past them by killing and restarting kwin from a linux console.)

[DoYouKubuntu]

@jlittle, I hear you! It's really gotten kind of ridiculous how many things control how many things... I used to know exactly what to choose to get the look I wanted, but now, as you noted, it takes a combination of different things. And, sometimes, settling for less-than-perfect results.

I have screenshots from previous versions that show how beautiful my desktops looked; comparing them to what I have now, it's actually quite disappointing. QtCurve, as its own entity, is still good, but some of its components no longer work, and I want them back.

But aside from that, other things--like no longer having separate wallpaper per desktop--seem like a *BIG* step backward. I used to turn heads (window$ users) spinning my desktop cube, displaying each desktop with its own wallpaper and widgets, and popping in and out...they didn't even know what 'multiple desktops' WERE, let alone that they could act independently of each other, AND be displayed on a cube you could rotate.

Now? For the first time in my Linux life, I've set my number of desktops to 1. Without separate wallpapers, I no longer have any pressing desire to use more than one desktop. And I've been multi-desktop for nearly 40 years!

As for my lockups, I had one today, so there goes the 5-day streak. But that's still better than multiple lockups per day. I really think there's a conflict...clash...somewhere, something that isn't obvious to me, but that happens at certain times/events and freezes everything up. I thought I was finally on to something, since the lockups stopped immediately after losing QtC, but now I don't know what to think.

What's the longest RAM test you've run since the problem started?
Most people run the RAM test for one cycle and if they don't get any problems they call it good. A better run would be over night.

You can get separate wallpapers for different virtual desktops with a wallpaper plugin like "Vallpaper" (https://store.kde.org/p/1197828/). Last I checked, it doesn't really work with the cube (the wallpaper changes only after you switch to a new desktop), but the cube is sort of "meh" to me, anyway. The configuration options for Vallpaper are extensive, and it can take a bit of effort to get it right (but on the positive side you do get a lot of options).

[jlittle]

+1 for Vallpaper. The cube (ctrl-f11) is a bit of a gimmick, looks cool but the scroll-wheel on the desktop or the pager widget are faster, and animate with the correct images with Vallpaper.

I haven't run a memory test, GG. As noted ^ up there somewhere, the System76 instructions for doing this call for a live disk, and mucking about with the BIOS mode. Considering how things have gone for me with this laptop, I am not keen on going there.

Yes, I tried Vallpaper (probably at your suggestion! I don't recall right now who it was), but it was clunky and not what I wanted. The ONLY reason I [recently] used multiple desktops was for the fun of having a beautiful, nine-sided cube, each with its own wallpaper (and widgets, when I knew I was going to show off to someone coming over). Like this from 2012:



Before I got sick, I used to use multiple desktops to organize tasks. For example, Internet-related stuff on one desktop, graphics on another, office utilities on another, and so on. Now, I just want my beautiful cube back!

Last night I installed memtester, thinking maybe it would help...somehow. I gave it a spin, but I'm wondering if anyone here is really familiar with it, and can guide me on how best to use it for the problem described in this thread. So, for example, running it overnight, then collecting its info and using that to figure out...something. Or am I barking up the wrong tree?
