About 70/30 of the time I'll either boot or reset into emergency mode for almost a year (very late to trying to fix this, I use this PC very casually)
I'm currently off work for awhile, so I figured I'd actually take the time to fix it

I have tried to make the switch in the past (a long time ago, in the RedHat 5 and...
Because in the past I have bricked installations (I was young and carefree back then ) I want to be very sure about the bootloader. But that was a long time ago, and things have surely evolved since then. What I want to do is:

• Retain the current Windows installation and the Windows boot manager on my nvme ssd.
• Install Kubuntu 26.04 on a separate ssd (sda)
• Have the bootloader for linux be separate from the windows boot manager.
• Be able to select both the windows boot manager as well as the linux bootloader in the BIOS as boot options. I want to set the linux bootloader as the default option. From there, I can then boot either into Linux or Windows. But if I want, I should be able to go into the bios and boot Windows directly. Either as a one-time override or by setting Windows as the default boot option again.

So now the question: if during installation I create a 512 MB fat32 partition with a boot flag and mount point /boot/efi, will the Kubuntu installer automatically use that partition for the bootloader? And will it leave the Windows boot manager intact? Or do I need to tell the installer explicitly to put the bootloader there? If so, where? I did not see that option anywhere in the Kubuntu installer. But iirc I did see it in the Ubuntu installer. Hence the question, I want to be absolutely sure before attempting this. ​]]> Help the New Guy Caelarius https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/691594-does-the-installer-automatically-use-a-newly-created-boot-efi-partition-as-the-bootloader-location https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/691580-how-can-i-configure-the-power-button-standby-issues-kubuntu Thu, 30 Apr 2026 06:58:10 GMT Hey everyone, I’m new to Linux and using Kubuntu right now.

Making my way to get used to linux on a desktop. I'm having problems booting up kubuntu after installing the latest nvidia graphics drivers. My kubuntuOS is version 24.04 LTS.

I have just built a PC with these specs:
CPU - AMD 9800X3D,
GPU - RTX 5070 Ti,
RAM - 32GB.

ALSO, I received this message when booting up kubuntu for the first time. What is it and should I be worried?:

'RDSEED32 is broken. Disabling the corresponding CPUID bit'


In addition I have also tried multiple times to download KubuntuOS 26.04 LTS onto a flash drive but had no luck with balena Etcher, so I used rufus but got this message before proceeding:

'The image you have selected is an ISOHybrid, but its creators have not made it compatible
with ISO/File copy mode. As a result, DD image writing mode will be enforced'.

Now my USB drive is split into 2 partitions, but I think it is OK to use to boot up the computer if I need to do a complete BIOS reboot/wipe. I don't have anything of value saved into my SSDs so it should be fine. Looking for feedback and workarounds ASAP as I tackle these issues this week.

Thanks in advance!​]]> Help the New Guy striderdx12 https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/691515-issues-installing-kubuntu-on-new-pc https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/691514-how-do-i-debug-performance-problems-are-colord-sane-and-or-snapd-known-to-be-raging-cpu-hogs Tue, 28 Apr 2026 02:51:14 GMT uptime reported load averages like 158.83 This went on for an hour or more, until I finally gave up and rebooted. I also note that the system had been up for 15 days, which might just be longer than kubuntu's tested uptime, given the frequency of minor updates.

While the KDE desktop was essentially unusable during this period, though not actually hung, I was able to ssh into the system and run top.

Really high cpu times were reported from kswapd0, snapd, systemd-jo+, plasmashell, colord-sane, and various kworker threads. (systemd-jo+ was presumably a truncated command)

"memory" usage was not notably elevated.

The "fun" started approximately when I launched a script that backs up user space to an external drive, using rsync.

---
What I want to know is how to debug this. I'd like to submit good quality bug reports to whichever upstream projects are responsible for the mess.

I'd also like to find workarounds, and possibly replace misbehaving packages with other sources of similar functionality. (Given what was on the list, that may be difficult.)

I'm an old Unix developer, and not afraid of debugging tools, profiling tools, or log files. I've even been known to look at misbehaving kernels.

What I don't know is what all these processes are or which packages they belong to. I also don't know much about current linux tools for debugging performance issues. I don't even know much about where it keeps its logs or how to read them. Is syslogd still a thing? On kubuntu?

My inclination from past experience is to suspect the desktop environment, broadly construed, but I'm a new user of kde and wayland (less than 3 months) with a corresponding lack of knowledge.

Is there a performance-debugging FAQ somewhere? Particularly one specific to Kubuntu, since I suspect involvement of both kde and snapd.

Is there a known issue?
---

Note that I don't plan to try too hard to sort this out while still on Kubuntu 25.10. The 26.04 LTS is available, and I'll probably move to it before the system's been up for another 15 days. (Why do you think I was running a backup?) But I rather doubt whatever bug(s) I hit will turn out to have been fixed in 26.04 - moved around a bit, maybe, but probably not fixed.

Also, FWIW, The system was up to date as of about 15 days ago, except for firefox, which I "pinned" after a forced update from snap was found in progress during my last Kubuntu not-quite-hang. The backup script on the other hand has been run many times without any similar incidents.

[Edited to add: I found dpkg -S. So I'm on the way to identifying the processes.

colord-sane is from the colord package, which is used by KDE. I can't really imagine why it accumulated so much cpu time.

Kswapd0 is the kernel page out demon, which should only be this busy if something is grabbing loads of memory. Maybe the backup thrashed the file system cache, particularly if it's a combined cache - executable pages and ordinary files together. Still odd that this hadn't happened other times that the backup script was run.]

I just started using Kubuntu.

In the Discovery Store I can download apps from Ubuntu or choose Snap. What download should I use?

I know that Canonical tries to mainstream apps as Snaps. But what consequences do either choices have in daily use?

I was persuaded to try Kubuntu in mid-2025 after having some issues with gnome-ubuntu. Although I was urged against this, I decided to use the desktop switching method to switch between kubuntu/plasma and ubuntu/gnome. These fears proved groundless in my case. Since doing the desktop switch, I basically have never looked back and have had no issues with the switch. I found that I greatly prefer Kubuntu. There is nothing in Ubuntu/Gnome that I miss. For me, goodbye Gnome.

So now, April 2026 and thoughts turn to upgrading the system. I think I will back up my system and do a fresh 26-04 install of Kubuntu, without all the desktop switching. But it seems to still be in beta, and I want to wait until it's in full release before doing it. Therefore, as a relative Kubuntu-noob, I'd like to ask the community veterans what is the typical interval between a release version of Ubuntu and the corresponding release version of Kubuntu?

Thank you!

I just tried Kubuntu 25.10 Questing Quokka on my Dell Latitude 7320 Detachable in a live boot session using a boot stick.

However, I think it fails to load KDE Plasma when I choose it as a desktop environment on the login screen. After logging in with Plasma(Wayland) set as an option, I still see the Kubuntu desktop, not Plasma. I'm not very experienced but I tell it from the Kubuntu startmenu icon which still shows up in the bottom left corner instead of the KDE Plasma icon.


Also the virtual keyboard doesn't work. When I click it in the login screen, nothing is showing. In the system setttings, there is only the option "none" to choose.

I currently still have Windows 11 installed, but I don't yet want to remove it, since I only want to keep this PC if I find a Linux OS which I can use it well with as a surface PC in tablet mode.

Do you have an idea what could be the problem here and how to fix it?
