Hi Aurelien & Matt
thanks a lot for your feedback! I just tried again. This time I was able to install Fedora 39 Beta Workstation. This time I took another stick. Not sure if that had any effect on it. So far it fits for now. Waiting for the final release now and will then switch from 39 Beta to 39 Stable.
Seeing the same behavior on my FW13 AMD with F39 KDE Spin. Initial install worked out of the box. After first boot to desktop, sddm crashes every subsequent boot causing blank screen after boot logo (both before and after most recent updates). Switching over to tty2 after the screen goes black and restarting sddm.service allows full login to the desktop. Everything else seems to be working after logging in. Attempting to logout or switch users also seems to crash sddm.
dmesg shows a kwin_wayland segfault after a bunch of amdgpu and [drm] lines on boot. Guessing that has something to do with the known kernel/firmware issue(s).
Just adding that I am seeing the same issue with the F39 Beta / KDE spin. I’ve reinstalled and immediately rebooted as well as reinstalled, updated, and then rebooted. Same issue in both approaches. Was hoping to be able to use the KDE spin because Gnome isn’t making fractional scaling available to me… 
I think there are some ways to do troubleshooting in this case. Though I haven’t experienced KDE. So, below is my guess.
Check the boot log: I think when you type the Escape key, you may be able to see the boot log n the booting process and the blank screen. Then when you type Escape key again, you may be able to change the log screen back to the blank screen again.
Try console mode: If the problem happens in the process of launching the KDE boot manager, maybe you can type Ctrl+Alt+F2 to change to the console mode. Then you may run dmesg to check the boot log, and dnf upgrade to get the latest RPM packages. You can type Ctrl+Alt+F1 to change back to the GUI mode. This is a thread I opened to fix a similar error in another desktop manager GDM (Gnome Desktop Manager)
Login with Singe user mode (rescue mode) by editing GRUB menu. - Working with the GRUB 2 Boot Loader :: Fedora Docs
I’d echo above. We do not provide any official support for KDE at this time, but this is a good jumping off point.
Then I ran Discovery and installed the 3.8 GB of updates.
After rebooting, screen is blank. There’s no way to boot back to the DE.
I’ve tried hitting F12 on boot to select a different option but they all end up the same way.
Does anyone have the KDE spin working on a 7040 with the 3.03 bios? Just got a notification that batch 2 is getting ready to ship and it’d be nice to know if it’ll work; I really don’t like gnome.
Thank you, junaruga! I haven’t had time test that but will give it a shot
What I’ve done as a placeholder is install the Gnome version of the F39 beta, then installed the KDE desktop group. The Gnome login screen loads fine, and Plasma works great once you get to the login screen, so I use the Gnome login screen to get into a KDE session. Not the best, but it’s a great way to get fractional scaling in a visually pleasant way. 
Hopefully this is a safe yet clunky workaround until the issue is resolved.
Not sure there is anything to resolve in this instance as it sounds like the method used to update was perhaps a contributor somehow.
Two things I need to disclose here.
We do not actively test against KDE, however, being a Fedora Spin, I tried it on 7040 with 3.03 BIOS.
BIOS releases are fast and furious right now for 7040, so folks reading this - it will not matter long term - this was merely a test.
Downloaded/USB setup a brand new ISO of Fedora KDE 39 Beta using mediawriter. Smooth install to the 7040.
Updated via the terminal, rebooted. Flawless.
Nothing attached except power. Running Wayland.
Thanks for sharing the workaround!
Agreed, we do appreciate your experience with this @Shibusuke.
Hopefully my above test, update method and whatnot is also helpful for anyone else.
Based on their workaround, I’ll mark this as solved.
Thank you for testing this even though it’s not in official support scope - this gives me confidence I may be able to get it working with a later bios.
Did I miss something ? So far, I coudn’t find the 3.03 Bios anywhere. It is still for internal tests only ? Any way to contribute before release even during alpha stages in order to give you guys some feedbacks maybe ?
Another data point here.
FW 13 AMD 7640u, 64GB RAM (g.skill), BIOS 3.02. Arrived today. Lovely machine.
Installed to encrypted SSD from Fedora KDE ISO.
First boot after install, login screen working. Logged in and updated via the terminal. Rebooted.
On boot after update (6.5.7-300 kernel), freezes at blank screen after unlocking encrypted disk. Manually switching to a console using Ctrl+Alt+F2, logging in, and entering sudo service sddm restart brings up a working graphical login screen.
Rebooting using the backup 6.5.2 kernel does not resolve the issue.
I have added an extract of the relevant dmesg output below, starting as soon as the GPU starts having issues.

There is a segfault pointing at the kwin compositor’s graphical effects, as loaded by the sddm login manager - not sure if this is the cause of the GFX card reset or a symptom.

The suggestion by @Shibusuke of using the default Fedora ISO with GNOME, installing the KDE desktop, and using the GNOME login manager should be an effective workaround. There is still an underlying issue here though - (potentially) flawed user-mode software shouldn’t necessarily be able to cause a reset of the graphics card.
What has been shipped with is what we want folks on at the moment. This is super fluid and will evolve. So unless you see a thread for the new BIOS, you’re where you need to be at this moment.
I did some more reading after my previous post, and these GPU resets with the “MES” error logs are indeed supposed to be fixed by the 3.03 BIOS - see comment 5 by Mario who is an AMD employee, he mentions MES specifically.
Some fixes that might be of interest - found these floating around the Framework discord server.
I have temporarily resolved both some white artifacts I was experiencing on external monitors, and my crashing sddm, with the following steps:
amdgpu.sg_display=0 in /etc/default/grub and regenerating grub config ( sudo grub2-mkconfig -o "$(readlink -e /etc/grub2.conf)" )sddm to use x11 instead of wayland by adding the below to /etc/sddm.conf
[General]
DisplayServer=x11-user
Shouldn’t be necessary in future.
Note that adding the kernel parameter and then still letting sddm trigger the BIOS 3.02 GPU crash leaves external monitors not working. So I assume that after the crash the GPU is in a bad state of some kind.
Just got mine and didn’t even have a working trackpad with KDE spin live environment.
Installing regular gnome fedora workstation, then installing plasma afterwards and just using gdm as display manager seems to be working perfectly so far as a workaround for me as well, I will probably just keep it this way rather than bothering to reinstall, even though I’ll never use gnome.
It seems that grubby tool is better to use in order to change everywhere not only for grub conf but also other scripts that may exist under /boot/loader/entries etc.
sudo grubby --args="amdgpu.sg_display=0" --update-kernel=ALL
Correct for Fedora, we would want you using grubby for a more consistent experience.
My own test and experience using 3.03 BIOS and Fedora 39 KDE is here 17 days ago.
If this is happening on Fedora 39 fully updated, it would be worth filing a bug report.
Came here from Google having similar issue on Fedora 40 Bios 3.03. In my case the built in monitor was set to a resolution not supported by KDE. I connected to an external monitor and then I was able to set the correct one. Posting just in case it helps someone else.
