I followed this advice (mentioned above):
https://www.reddit.com/r/Kubuntu/comments/1cdko49/comment/l1uf573/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
It seems that "quiet splash" is the actual problem, not "nomodeset"
(solution).
I edited the GRUB entry as follows (with results added):
1) With only "quiet splash" (no "nomodeset"), default installation,
fresh install of Kubuntu 24.04: only black screen, nothing happens.
2) Add "nomodeset" to "quiet splash": everything works perfectly. Also
works permanently with editing of /etc/default/grub.
3) Delete "quiet splash" in GRUB and do not add "nomodeset" (or delete
"nomodeset", if previously added): everything works perfectly (see
Reddit link above).
4) Delete "nomodeset", after having added it to /etc/default/grub and
updated grub previously, but leave the 'original' "quiet splash":
computer hangs, completely unresponsive, after showing the following
code:
Booting a command list
Loading Linux 6.8.0-31-generic ...
Loading initial ramdisk ...
5) Again, boot without both "quiet splash" or "nomodeset": everything works
perfectly. Also works permanently with /etc/default/grub.
It went quite fast, but after "Loading initial ramdisk ..." I think the next
code line was "enabling secure boot". It might be a problem with "secure boot"
and "quiet splash". Secure boot is enabled in both my installations, so I can't
try the other option ("secure boot" disabled in the EFI BIOS before
installation).
Workaround (for me):
- Edit /etc/default/grub: the line "GRUB_CMDLINE_LINUX_DEFAULT=". Delete the
words "quiet splash" (leave the quotation marks '').
- Run sudo update-grub

Title:
24.04 Upgrade/Fresh Install results in black screen on reboot on
AMDGPU system
Status in linux package in Ubuntu:
Confirmed
Bug description:
Config: Ryzen 5 5600X with Radeon 6700 XT GPU, a Navi22 card.
Using xUbuntu.
I had been daily driving the 24.04 nightly iso since March. About a
week ago, I took a kernel update via apt and rebooted. The result was
that the system would hard freeze to a black screen after the initial
kernel messages cleared from the screen. Ctrl-Alt-Del did nothing,
switching terminals (ctrl-alt-f#) did nothing, had to hard power off
to regain control of the system.
I tried various fixes, none of which permanently stuck. This includes
nomodeset in grub, rebooting into safe mode, checking for proprietary
drivers. Safe mode allowed me to reboot once more into desktop, but
then any subsequent reboots would result in a black screen lockup.
Suspending while able to use the desktop before reboot would cause a
black screen lockup did not seem to cause any issues.
3 days before 24.04 was officially released, I reflashed the most
recent installer iso to my thumbdrive, copied my home folder to my
RAID and did a full wipe and fresh install.
First reboot after installation always went to the desktop. Subsequent
reboots always resulted in a black screen lockup.
Memtest cleared without errors.
Again tried various fixes, nomodeset, safe mode, drivers. The only
consistency was that regardless of what I could do to regain control
or what I did differently when doing a wipe and reinstall, I would
always reboot to a black screen.
Once 24.04 was officially released, I again did a full wipe and
reinstall and encountered all of the above same issues as before.
After mentioning this in #ubuntu on libera, someone suggested a kernel
downgrade.
24.04 as installed was using 6.8.0-31.31
Using Mainline, I downgraded to the next minor version below 6.8 that
was considered stable. 6.7.10
Problem went away. No more black screen on boot, no more hard power
offs required to be able to use my system again, no suspend issues.
Was not necessary for me to do anything else to maintain a consistent
successful reboot to desktop.
Did yet another full wipe and fresh install of 24.04, only installing
Mainline upon first reboot to install 6.7.10, using Grub Customizer to
edit the default grub option to boot the 6.7.10 kernel instead.
No issues.
I apologise that I did not collect logs during this process.

For those affected by this issue, this was my fix:
Install 24.04, reboot, at the desktop, open a terminal window and add
the following PPAs:
sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
Run mainline-gtk, install kernel version 6.7.10
run grub-customizer, move "Ubuntu, with Linux 6.7.10-060710-generic"
to top of list, making it the default option. Save and reboot.
