They have the same processor, an Intel Core i7-6500U, same amount of RAM memory, same SSD HD size. One of them is running Kubuntu 24.04.4 LTS and the other one is running Windows 11 Pro using a balanced Power Plan.
I have run the Geekbench CPU Benchmark in both of them and the results are much better in the machine running Windows, which was surprising to me. Is there any explanation for that?
For the Windows machine the single core score is 1092 and the multi core score is 2203, while the Linux machine got scores of 849 and 1488.​
I checked the Power Management settings of the BIOS and they are the same as well.
Thank you

On Wednesday 25th of March there was a download of aprrox 1.1GB while accessing a few... while accessing a few pages with Palemoon 34.1.0. Discovery had already installed updates. Does Kubuntu ever download updates or anything else this big without asking permission or showing some indication on the screen of what it is doing? Or has my system been compromised, Palemoon perhaps? I always login in to Standard User account and never click on links in email,etc. Thanks for any help I receive.

I am going to start this off with a preface and note; This is NOT a post to debate the pros and cons of any actions be it removing x, or adding x! (Hey a pun too!) Period. You can guess the package(s) I am referring to!
This is a DISCUSSION to see what others do to customize their new installs. To meet their needs....YES some of these are very very VERY PERSONAL CHOICES for well, reasons.. This is not about the reasons why, good or bad. I got my reasons why I do things, you got yours. You don't most likely agree with my choices on removes/adds, etc.. Not the point here.

I think this makes the point to keep the rhetoric on point.

The backstory to all this is that over the past 5-6 may be more years there has been more and more and more that I need to change from the base install. Some of these changes leave me scratching my head, some are rooted in the reasons I mentioned above.

I am working to a goal here which is to create a SCRIPT, likely a BASH script to do all this stuff I have to do to a base install to get it back to "normal." This is true since 26.04 is likely to be the LAST HURRAH for me and the sheer number of machines I've got to update, and the time to do that is well daunting to say the least.

BUT

I am curious as to what others do to a FRESH INSTALL to customize for YOU?! Why? Curiosity - how far off the deep end am I? A: Probably very very far! , discussion, and maybe there is stuff I am missing to tweak.

Things I do:

DM change - LightDM as I require XDMCP - Did this since the demise of KDM and KDM 2.0 , not an option - see above.

Install Xserver-Xephyr for the above

NEW: Reinstall X11 - remove wayt**** I am BRUTE FORCE REMOVING THIS. As the proper way will nuke the desktop, ask me how I know!? NO I don't want it laying around. A little sudo rm on stuff and bye bye! It won't show in LightDM or work if you try it! Good riddance

NEW: chmod reboot/shutdown so it REQUIRES sudo on local use - shakes head.

Disable ALL automatic updates of any thing. No thanks. See above.

Desnap everything and block any snap installs

Reinstall firefox via DEB
-Lots of firefox customizations ie: ad block, cookie eaters etc.. not sure that any of that is scriptable.. sigh...

Disable power saving -

Revert to PROPER 24H time on digital clock in taskbar and lockscreen and LightDM

NEWish - Fix dmesg to NOT need sudo. Nope, don't agree on this one.

RESTORE Unix mouse click ie: SINGLE CLICK

Install openssh-server - I think I know the reason why and meh.. again, see above.. Just a statement of I disagree, nothing more.

Install krfb - krdc is installed? but krfb is not Ummmmm.. ok...

Install the basic netools package for DNS stuff etc.. this is sort like KRFB.. these were there in the past. NO I don't subscribe to the less is more on the ISO.. I been on the "wrong" side of this debate since Knoppix and doing ISDN DL's. so..

Install synaptic - even though it appears its still borqd for the proper search mode - Although I thought that was addressed doesn't seem to have propagated... sighhh.

Install various SDR related packages for systems which do it.

Set Konsole to have its profile transparent for.

NEW: install btop - nice little enhancement.

NEW: I am possibly adding KVM support packages to this, but I have issues in re networking on KVM ie: bridge and possibly X11 issues ie: XDMCP in a VM.... If I can't resolve them, then KVM is not an option. I may have a solution in one, networking but its a kludge I find not needed, ie: 2nd LAN card. Ran into a snag on the box I wanted to test this with, and have to try on something else (its a box itself issue, its weird honestly). I'd really love to use KVM in place of VBOX, I ditched VMW a long time ago, and the last nonsense with them sealed their demise....

Things I'd love to do, but have not found them since KDE 4!

RESTORE the GLORIOUS COLOR OF KDE3 ! I have a box that still used KDE 3 (This one will be a casualty as I have a replacement for it built) and the startup screen and the bouncing icons, and the BEAUTIFUL COLORS of the taskbar v. the Gulag Theme of KDE 4 and since??!? Good grief.. bland. bland bland. I've tried every "theme" I can find to try to get the vibrant KDE look back.. I finally gave up.. Gulag it is. This I've never gotten.

SO whats YOUR MUST HAVE tweaks for a fresh install (remember keep the first graf in mind! Some reasons is fine, arguing over the pros/cons of a package or choice is NOT!)]]> Community Cafe rec9140 https://www.kubuntuforums.net/forum/general/community-cafe/691050-what-do-you-do-to-a-fresh-instal-to-customize-it-for-you what is a TPU - and why should you care https://www.kubuntuforums.net/forum/general/community-cafe/691043-what-is-a-tpu-and-why-should-you-care Sun, 22 Mar 2026 07:11:51 GMT i kinda find it interesting ,to say the least
thought i'd come and share it here

Why Does Any of This Matter?
Because AI is no longer a research experiment. It's infrastructure. Every major product you use — search engines, photo apps, navigation, virtual assistants — runs on chips like these. Understanding what powers AI helps you understand where technology is genuinely heading, not just where the hype says it's going.​

EDIT: oh , and then there is this too ...

Yesterday, Kwin crashed on me once and this morning it crashed just after I logged on. It looked in the log like there might be a memory problem:

But I ran a memtest (Passmark memtest 96 V8.4) for a good half hour and it found nothing. Btw, it seems to me there are far more entries in syslog than before. The above log entries seem to be from before I logged in.

Later on, there area bunch of messages like this:

This would seem to indicate my logon:
