What I’ve Tried:

I got the computer into recovery mode, connected to network then updated everything from there. I can now “resume” from there but the graphics are struggling and seem to be running off the cpu and anything strenuous freezes the computer. I was looking to reinstall the drivers but they seem to be baked in.

AMD graphics drivers are open-source and already in the kernel. Make sure your system is fully updated.

Then, you may want to try the ‘overlay’: https://www.amd.com/pt/support/download/linux-drivers.html

According to the system updater, my system is up to date, unsure if I should be checking elsewhere.

I installed the driver off the AMD site, then ran a apt-get update that grabbed a bunch of stuff for the item it installed. After a reboot, I have the same issues.

Getting the very same issue on both 24.04 and 25.10 standard Ubuntu. The only thing that worked for me so far was to pin my kernel version on 6.17.0-8 specifically. Every single kernel update since then is completely borked and behaving exactly like you describe. I just tried 26.04 beta and I can only boot in safe graphics mode and no, setting nomodeset doesn’t fix anything.

Try disabling the splash screen and you will see no errors but it just hangs. The keyboard should respond to a CTRL+ALT+DEL and you will see console output flowing normally.

If you carefully debug the journal for errors surrounding the AMD GPU initialization, you won’t find anything wrong.

It really seems like the kernel did everything right and then it passes the hand onto Wayland and then Wayland just won’t boot Gnome, thus the splash screen staying visible. I guess we should have a look at what Wayland is doing.

I’m experiencing the same problem. Ubuntu hangs on startup, my screen stuck similar to this published. I need to add ‘nomodeset‘ at the grub command line to boot OK.
I had changed C-State on BIOS, hed teste a lot of BIOS settings without success.
My configuration is:

uname -a
Linux casa 6.17.0-20-generic #20~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Mar 19 01:28:37 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

CPU/GPU: AMD Ryzen 5 8500G w/ Radeon 740M Graphics

AMD Driver INSTALLED: amdgpu-install_7.2.1.70201-1_all.deb

After hang, I booted with Ubuntu Installation and collected ALL /var/log files:
/var/log/boot.log ends in:

@mistermattler

I offer a little bit of information. Advance Options for Ubuntu>Linux kernel with recovery mode>Recovery menu>Resume will load (hopefully) to a desktop using an open source video driver. That is perhaps the reason that the graphics are struggling.

I am unfamiliar with the Cinnamon desktop. So, I will suggest some commands to use.

ubuntu-drivers list

That will show all driver packages which apply to the current system.

ubuntu-drivers devices

That will show all devices that need need drivers, and which packages apply to them.

ubuntu-drivers autoinstall

That will install drivers that are appropriate for automatic installation.

These commands are useful for when we cannot access a desktop and user interface. You can access the desktop but I do not know what utility Cinnamon has to install proprietary video drivers. So, I cannot advise you on this method.

Regards

SOLVED for a short time (I BELIEVE)
After a update/upgrade stop working. I don’t know what works and stops. Modules-extra is installed on update, I remove it after upgrade and GPU works fine, WITHOUT SOUND.
I believe that there are some conflict between drivers in modules-extra and AMD drivers.
Explaining my tests:
I did a lot of tests with old kernel versions (6.11, 6.14).
I install using sudo apt install linux-image-6.XX.0-ZZ-generic -y
In all tests GPU works fine, but did not recognizer NETWORK, because linux-modules-extra was not installed.
Finally I had installed kernel 6.17.0-19 (sudo apt install linux-image-*6.17.0-19-generic -y), GPU works without NETWORK, after that I install extra modules (sudo apt install linux-modules-extra-6.17.0-19-generic), GPU but without NETWORK. So I remove 6.17.0.20 extra modules (*sudo apt remove linux-modules-extra-6.17.0-20-generic -y). Boot with 6.17.0.20 kernel without NOMODESET, and everything works fine.
*
SUMMARY:
With ‘nomodeset’ active
Install kernel 6.17.0-19:
sudo apt install linux-image-6.17.0-19-generic
Install kernel extra modules 6.17.0-19:
sudo apt install linux-modules-extra-6.17.0-19-generic
Boot Advanced mode and choose 6.17.0-19 with ‘nomodeset’ active
Remove kernel extra modules 6.17.0-20:
sudo apt remove linux-modules-extra-6.17.0-20-generic
Remove on ‘nomodeset’ on /etc/default/grub , update-grub of course.
Boot normally with kernel 6.17.0-20.
This works fine to me.
I don’t know why, but works!!! WITHOUT SOUND

not solved totally yet

NOW is true: SOLVED.
Download from AMD Support website, the driver Ubuntu version and install it.
remove from blacklist.conf if exists.
sudo ./amdgpu-install --uninstall
sudo ./amdgpu-install --usecase=graphics,opencl
Follow instructions.

Is running WELL with SOUND on HDMI. It’s with BIOS SECURE BOO enable or disable.
