Just tried Desktop Session: Plasma (Wayland) on my 22.04 install

[GreyGeek]

A year has past and I just switched to Wayland. The touchpad setting has the checkbox "Device enabled". I checked it and hit "Apply". The touchpad is off.

Now I'm going to see how stable it is.

It's been a week since I switched to wayland. The experience has been much better than a year ago. My Intel Iris Xe is working beautifully and is very fast. Apps snap to the screen. My gold standard, Universe Sandbox^2, works great. A new Hires simulation, Starbase Simulator, works great.

With this power consumption limit the only AMD graphics card for you would be a Radeon RX 6400 (max. 53 Watts - max. power consumption in real world tests is more like 43-45 Watts, though).

PS: Here is the first comparison I found: https://www.youtube.com/watch?v=wMcv0FyRmQQ

I just tried it again and this time I actually got to the desktop. Most of the nVidia settings were missing and X-Plane 11 refused to use Vulkan and defaulted to OpenGL.

I'm back on Xorg once again. Now, if I can find an inexpensive AMD card with similar spec to my NVIDIA GeForce GTX 1050 Ti 4Gb card I'd go for it! (power consumption must be max 75 Watts)

Since X11 isn't going away any time soon I will give it another try next year.

For me and my 4k monitor, choosing between X11 and Wayland on Plasma feels like a lose-lose situation. If I go with X11 (200%) I have to live with all sorts of KWin elements which remain unscaled. No surprise since you have Plasma, Qt and KWin all having their own scaling logic. Some GTK apps like Timeshift also don't scale properly and look atrocious.

If I go with Wayland, I have to deal with blurry upscaling of apps running with xWayland. VLC, Steam, Timeshift, a lot of snaps etc are all affected.

And here comes the kicker: none of these problems exist on Gnome. I so want to use Plasma that I exchanged my Nvidia card for an AMD GPU. But I am less inclined to now also sell my 4k monitor, so I can run Plasma unscaled on FHD.

I switched back to X11. Wayland had too many little niggles that interfered with the operation of the desktop.
For example, pop open a menu on foxpro and move the mouse down the list of options. The highlighted option is often one or two options or more above the option underneath the mouse pointer.

Since X11 isn't going away any time soon I will give it another try next year.

For some reason KDE Dev's choose to eliminate that function.

The other are probably applying a workaround (such as a custom udev rule or device quirk), as libinput iirc doesn't have such an option in itself.

In any case, it wouldn't be Linux if we didn't have something to gripe about, and someone blame

I also forget I an probably the 'youngster" here. I should be used to to the cane-shaking
I''ll shut up now,

I'll Second Snowhog's comments and add with my touchpad even with the setting disable while typing it still cause the cursor to jump while I'm typing. Which cause real problems if i'm typing fast.
It sure would be nice to have that setting back. Like I said there are work a rounds but they are not KDE centric. On Mint Cinnamon the option is there. But not in Gnome. I know Mint uses libinput so it can be done there also. For some reason KDE Dev's choose to eliminate that function. But they may have had good reason. Just wish it was still there.

To which I'd reply: "I don't want an active touchpad when my mouse is plugged in, which it always is. I don't like touchpads. I don't use touchpads. I want the touchpad OFF when the mouse is plugged in. Period."

AMEN to that!!

[GreyGeek]

Amen! Preach it, Bro!

[Snowhog]

If we have palm rejection (ie disabled while typing), why exactly do we need to have the touchhpad disabled with a mouse plugged in?

Well, for me, my laptop has a small-ish, off-centered touchpad, and my palms barely make contact with it when typing.

One might then opine: "What's the issue then? If you aren't contacting the touchpad, then it isn't controlling cursor movement."

If you install debian KDE it's still there i

Debian and MX are old enough that they are still using the old, unmaintained/abandoned synaptics driver over the kernel driver (libinput). It is a general Linux thing, and not specificc to KDE in any way.

Ok, I am having brane fahrts while investigating, so while I do kinda know the answer, I am looking for search inspiration:

I am trying to discover why this isn't an option in libinput, and only finding rabbit holes :O (this issue is all Red Hat's fault lol)

For me, neither Kubuntu, since I can't remember when, nor Neon, since I first installed it last September, have the option to turn off the touchpad when the mouse is plugged in. Now, as you know, it supposedly disables the mouse when one starts typing, but I don't see an option to set how long it turns off, and while typing I've had the cursor leap across the page to other locations while typing.

It used to be an option to disable the touchpad when mouse was plugged it but it has not been there for at least several releases of plasma now. If you install debian KDE it's still there in that version which is quite old now. I think MX-KDE it's also there. I kind of miss it wish the dev's would put it back in. But touchpad-indicator via PPA works well also. (Note: if you are using 22.04 you will need to change the ppa to focal to be able to install it since they wont' upgrade the repository until sometime after final is released.)
Wayland seems to be working well here. But haven't really put it to any tests yet.
My old fingers don't work well with a touchpad any more

I had never considered using Wayland and always thought that it would automatically become the default setting sometime "soon". I just set Wayland as my default DDM.
I am using the 5.14.0-1024-oem #26-Ubuntu SMP Thu Feb 17 14:35:50 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux kernel.
Glxgears only shows the vert refresh rate of 60fps, as it did in X11. Testing some graphical apps my Intel IRISxe GPU is running great. I just finished a round of solitaire to see how the graphic speed was, but my acid test is UniverseSandbox^2, which runs as smooth as silk.

So, I'll stay with Wayland until it barfs a lung.
