Master Boot Record (see previous toot for a great song) is a musician who remains painstakingly "on brand" and I freaking love it.
Here are screenshots of actual text-based logos included with one of the albums.
set your clothes on fire
video=1920x1080@60me to my kernel parameters.
Tried dumping my monitor EDID.bin and specifying that specifically on boot. No dice. same dmesg output as before.
I only have two other ideas for this as a whole: Either I have a faulty/old/outdated HDMI cable (SOMEHOW, it COULD be possible), or this is a kernel/amdgpu bug. If it's the latter, that'd be annoying.
So, more problems with AMDGPU.
AMD GPUs require KMS, so I can't have
nomodeset when booting my system. I used
nomodeset to install
linux-firmware and made sure that all my other amd firmware stuff was up to date.
No dice! the screen is still black upon switching to amdgpu.
NOW! I was like "oh, uh..." and devised a plan: with the screen still black, mount a usb and do
dmesg > dmesg.txt in the usb to analyze on a working machine.
I do that, and I see that
amdgpu SUCCESSFULLY INITALIZES, but there's STILL the black screen. I'm actually lost at this point. This is ridiculous
looks like the firmware on the live image doesn't support my cpu graphics. adding nomodeset in kernel config fixed the issue.
update: I set loglevel to 7, and now realize that the computers hangs exactly when it switches framebuffers to `amdgpudrmfb`
this actually has posts online about it, which is nice https://forum.level1techs.com/t/fb0-switching-to-amdgpudrmfb-from-efi-vga/152112
boosts appreciated; I'm having an issue with booting Void Linux on a USB. Read all.
I boot up the live image, I get presented with a GRUB screen, and once I choose either option, I am presented with a bunch of
too many entries: ignoring messages (which I doubt are relevant), then a black screen.
I search online and find this Ubuntu ask thread https://askubuntu.com/questions/1138820/black-screen-after-grub-selection-boot-from-usb-live. I try putting in
acpi=off in the GRUB kernel configuration. This did change something, that being that instead of the screen going to black after the
too many entries messages, it just freezes (see img).
With the screen frozen, I try doing what I know is familiar. If I press the numlock key on my keyboard, the numlock light indicating whether it is on or not does change, hinting that stuff is working in the background. I type
voidlinux to login, then try
shutdown -h now. After a few seconds, the numlock light stops responding to me pressing numlock, proving that stuff is still working in the background. However, the system doesn't shut down, and I assume this is because the graphics are hung. If I press the power button in this state, the machine instantly shuts off, making me believe even more that this is a graphics issue.
I have a MAG B550 Torpedo motherboard and a Ryzen 5 5600G Integrated Graphics CPU. I have not tried everything that's in that aforementioned ubuntu ask thread, but I might do so after making this post. I'm simply posting this in case anyone else has ideas.
