Review of Resolute Raccoon Kubuntu 26.04 LTS

[skyfishgoo]

seems like dejavu all over again...

did you try deleting "quiet splash" from the kernel parameters in grub?

I'm unable to log into Kubuntu 26.04 since Feb. 5th. If I update all the packages I end up with a non-working install. It boots and the login screen appears, but when I attempt to log in,, it goes to a black screen and stays there - no apparent activity at all.

In the last working version I have, syslog ends with:

I can't seem to find the problem but it looks like the splash screen is what's locking up.

I have left it alone for hours and it shows no activity at all after the above.

will Wayland be installed by default

It will be installed, but the x11 login session will not be removed.

Will Snap be installed?

Probably, but that may depend on how you removed or disabled it.

What would be the best way to upgrade from Kubuntu 24.04?

There is only one way, using the official Ubuntu upgrade tools., either from the notification you will see circa October, or started manually after upgrades are enabled at some point after release.

[deadsplash]

If I perform a manual system upgrade once Kubuntu 26.04 is stable, will Wayland be installed by default or will X11 remain? Will Snap be installed? What would be the best way to upgrade from Kubuntu 24.04?

Thank you for your attention.

P.S. The new version looks great.

I am referring to the issue with Wayland and it's inability to implement a system-wide pasting of completed snippets of text or code

Before Kubuntu 24.0

Wayland existed, or was available, well before Kubuntu Noble, and even there, it is not the default, and one needs to physically install the Wayland session package to even be able have it as a login option in SDDM. So I suspect something else it at play, maybe a bug.

[tenplus1]

barfly - I use copy and paste a lot in the Kubuntu clipboard and haven't seen any problem doing so throughout all my apps, although pasting in an entirely different desktop is not a thing I use and I wonder why this should be an option at all?!

[barfly]

claydoh and tenplus1 My apologies for not responding earlier. I am not referring to shortcuts as in links to applications or files/folders.

I am referring to the issue with Wayland and it's inability to implement a system-wide pasting of completed snippets of text or code to any desktop or activity. Before Kubuntu 24.01 there was a very simple system application to implement this in the system keyboard menu. With the introduction of Wayland, that has been quietly dropped for obvious reasons.

This has very serious ramifications for many users that are so used to a keyboard shortcut to insert a passage of text, an address, email address or snippet of oft-used code into a document or text.
The ramifications on the productivity of users so used to this facility is enormous.

Even in Windows it is a very simple thing to set up.

This is the primary failing of Wayland and one reason for the massive backlash against it's precipitous introduction. A form of keyboard logging across applications and desktops is required for this to be implemented - the antithesis of the whole philosophy behind Wayland.

I do not see how it is ever going to be resolved, but if Wayland is to be implemented wholesale across the Linux world we will be driving many workers back into the arms of Microsoft and Apple.

Looks like the same error as: https://bugs.launchpad.net/ubuntu/+s...p/+bug/2146570

Yep I reported there.
It also same in gnome on ubuntu 26.04 beta. I think it maybe a PY 3 thing. But it's above my pay grade

I found one small problem. HPLip-gui package installs but will not run. Work on 24.10 but not 26.04.
when you try to run hp-setup in terminal get this output.

raceback (most recent call last):

Install 26.04 beta and has been working fine for me, no major problems here. on my little laptop anyway. So think it should be good to go on April 23rd.

Your excellant list of the current state of Kubuntu 26/04 shows the 1 month to go before its release. It will be released on the 23rd April, and no doubt we will all be looking forward to its status on that day.

[notabug]

So far, so good. Just finished install and usual applications.

[acheron]

'fastfetch' doesn't list correctly, but 'sudo fastfetch' does.

BTW: I don't have a screen attached to the laptop as the laptop was dropped and the screen was shattered and so was surgically removed. I have a Dell monitor connected via HDMI.


PS: Don't know how to copy/paste the text output correctly so I screengrabbed.

Fix should be on the way: https://bugs.launchpad.net/ubuntu/+s...h/+bug/2146607

Hello all,
I've tried beta and last snapshot last 2 days in VM. Live session work fine, but after installation it's completely broken. As soon as I try to type something, program and plasma crash. I tried it in KVM and VMWare Workstation, it's the same.

[kernelbasher]

Actually iwlwifi
seems depreciated so I am having to use
iwlwifi disable_11ax=Y
Had the same in openSuSE Tumbleweed too with the new 7 kernel
