Well, my first experience with Fedora KDE Plasma was, to put it politely, full disappointment.
I wanted to install Fedora KDE Plasma on my HP ProDesk (as much as I can remember, you’ll see why not more):
• Intel Core i5-4570
• HP Memphis-S motherboard
• 16 GB DDR3 RAM
I’ve downloaded:
• Fedora-KDE-Live-x86_64-41-1.4.iso
• and FedoraMediaWriter-win64-5.2.3.exe
I’ve made the live USB, and started Fedora Live. It mostly worked fine (I was able to connect to my wi-fi hot-spot, surf by Firefox, print some docs to pdf and open them … ). There were some problems:
• I was unable to change the keyboard layout
• the time on the clock was wrong
OK, that will probably go better once I make the instalation on my SSD, I hoped.
I wanted to see how it goes with app instalations. I installed soduku game (KSoduku). It did not start. It’s icon appeared on the apps menu, but a click on it did nothing. OK, let it be.
Time to try it for real.
Start > Turn Off
Nothing! Absolutely no any response from the machine.
Start > Log Out
Nothing. I had to do hard reset (by physical power button on the HP ProDesk, and I’ve got the desktop again. From there, I started the real installation on the SSD. The installation went as expected, but when it finished and I wanted to restart the OS, after some initial screens from BIOS and Fedora’s “sand-clock”, I’ve got only the scrambled screen.
Hard reset again. The same again, only the screen was white this time.
And again the same.
I’ve tried to boot from USB stick again - white screen again. My comp was dead!
What can I do?
hi, welcome… sorry this has not been going as planned.
two things stand out from your story.
one is there already seems to be evidence of some incompatibility with your hardware given the live version did not behave as expected…that’s usually a bad sign and the main reason why live USB forms exist.
two the software used to create the bootable USB could be causing issues as well.
what i suggest is re-download the fedora .iso and be sure to verify the copy before you proceed to making a new usb
then i would get a different USB and use different software to make it bootable with the .iso on it.
ventoy.net is a great tool that works on windows (assuming you are using a windows machine to make the USB)
lastly i would comb thru the bios of the target machine and make sure there are no settings turned on that could interfere with your install or live boot.
turn off things like Fast Boot and Secure Boot… if you are not sure ask here or on fedora forums about which settings are OK with fedora and which are not.
Thanks, skyfishgoo, I’ll follow your advice as soon as I catch enough time and peace, hopefully¸soon (I reach Internet across LTE, and it’s sometimes very, very slow).
Also, I’m thinking about disabling the graphic card in the machine (NVidia G-force 1010), and enable the graphics in CPU (Core i5) in BIOS.
This time, I’ll write down (on papier!) every information I can reach, about every step, and I’ll let you know how it went.
TLDR follow the archwiki link below 
Windows puts your BIOS clock on local time, and adjusts it to show other timezones.
Linux puts your BIOS on UTC time, and adjusts it to show other timezones.
So if you boot one, after the other has set the clock, then you will find that the clock is wrong by the magnitude of your UTC offset. After time, it will sync from the internet, and the problem will reverse.
You can configure one to act like the other, so they both act the same and it all works… and the best way to deal with it is to configure Windows to use UTC like Linux does.
This was unsupported for a long time (but used widely in the commercial space regardless) so you may find references telling you to not do this. Specifically, there was once an update that had breakage related to this feature, and even Microsoft blamed their users for using this key.
Times have changed and that is no longer the case. Here is one current example of Microsoft official direction to use it (for running Windows VMs on a Linux host)
Hope that helps with that little problem.
The driver for that is probably the source of your woes. That’s more a fedora thing, than a KDE thing. skyfishgoo’s advice above is solid.
Thank you, pallaswept, it’s nice to learn how does Linux put BIOS time. I didn’t know anything about it before. I’ll study the subject following the links you provided, so to learn something new. Anyway, once I installed Fedora KDE Plasma on SSD, the time was correct; it was wrong (probably by the magnitude of my UTC offset) when Fedora Live booted from USB, so I didn’t see it as a problem, just as a possible simptom.
The NVidia driver is another pair of shoes. If it does turn out to be problematic, I really believe that it had to be mentioned LOUDLY AND CLEARLY on both the Fedora and the KDE web-cites because, as you can see, it can lead to quite a serious problem.
i keep a pad and pen next me and i also keep notes on the computer, there is a lot to learn about linux, but it been worth the effort.
as Pallaswept noted your time issues could be related to the dual boot thing, that was one of the first problems to solve.
from my notes
## SET LOCAL TIME ##
timedatectl set-local-rtc 1 --adjust-system-clock
this forces linux to use the bios time instead of UTC and seems to work except possibly for shifts due to DST if you have that where you are ( i hate DST btw).
as for the nvidia, if fedora is anything like ubuntu there should be an option in the installer to install proprietary drivers … if you leave that blank or say NO, then the kernel divers will be used instead and they are perfectly fine for your desktop GUI and light graphics stuff like office suite activities.
you can always try to switch to the proprietary drivers later if you find you need to.
better luck on your next try.
This seems to be more the issue
You can try to boot on safe graphics mode and then install nvidia drivers following these instructions
Also secure boot instructions
The issues you talk here i have seen similar issues multiple times wnd most of the times nvidia drivers fixes the issues
Thank you, people, for your time and effort! This is my first dive in Linux, and I can already see how true the statements about the community that I’ve been reading all around are.
However, it will take some serious time to understand your advice and the material behind the links you provided. Since I wrote about the problem, I gave KDE another try, and discovered that there are no some features I’d like to have, or they are not reachable in an obvious way (for example, multiple desktops), so I’ve tried GNOME 47 and it has what I want.
Thank you, people, again for your time and effort, I wish you all the best!
