Hey folks, total Linux noob here. I have a fresh installation of Fedora Workstation 40 running on a Lenovo Z41-70. While trying to boot the live USB for installation, I just got a black screen. It only worked after adding nomodeset in one of the run commands. I installed Fedora and now everything seems to be going fine. However, when I connect my computer to my Samsung monitor via HDMI, it appears Fedora does not recognize it (inxi -Fzxx):

I am unable to connect to my monitor, possibly because of an apparent lack of a driver for my AMD graphics.

Here is my /etc/default/grub if that would be of any help:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="nomodeset rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true

Thank you all in advance for your assistance.

The AMD Topaz XT appears to be a Graphics Core Next 1 (Southern Islands) card: Radeon 200 series - Wikipedia

Southern Islands support is disabled by default in the amdgpu driver:

$ modinfo -p amdgpu | grep si_support
si_support:SI support (1 = enabled, 0 = disabled (default)) (int)

You’ll need to manually enable support for your video card by adding amdgpu.si_support=1 to your kernel command line (instead of nomodeset): AMDGPU - ArchWiki

Edit: Actually, I’m not sure I’m reading the specs right. Is your laptop an older model from around 2015?

I found a review of this model dated August, 2014, so a decade old.

Yes, it is an older model. I only got my hands on it recently and it had Windows installed. It is actually surprisingly capable, being able to run various modern PC games at decent framerates. Here’s the full specs:

Now, I edited GRUB_CMDLINE_LINUX in the grub file to GRUB_CMDLINE_LINUX="amdgpu.si_support=1 rhgb quiet" However, it would not boot once I restarted until I temporarily added nomodeset back.

Not booting with the amdgpu driver enabled might be a separate issue. That problem has come up a few times on this forum recently.

Does it boot if you use modprobe.blacklist=amdgpu instead of nomodeset?

If so, what happens if you then run the following command?

$ sudo modprobe amdgpu si_support=1
6

It does indeed boot. However, running $ sudo modprobe amdgpu si_support=1 makes everything freeze up. I left it for like 10 minutes but it still wouldn’t unfreeze so I rebooted.

7

I think there is something wrong with the amdgpu driver in recent kernels.

Here is another idea if you feel up to trying it – downgrade your kernel (and the associated amdgpu driver) and see if that works. You will still need to supply the amdgpu.si_support=1 kernel parameter for it to have a chance of working.

$ sudo dnf --repo=fedora --releasever=39 downgrade kernel*

The above command won’t remove your currently installed kernel, but it might remove an older kernel depending on how many you have installed and how many your system is configured to keep.

I don’t know if the older kernel will be selected by default when you reboot. You might have to manually choose it in your boot menu. After you’ve rebooted, the command uname -r should print out what kernel version you are running on. With luck, the older kernel and driver will work with your hardware and hopefully someday a newer driver will also work (but you might have to stay with the older one for a while).

Hi,
I’ve had a similar problem and tried amdgpu.si_support=1 along with the various other settings to try and get the amdgpu drivers loaded, I’ve had success but not from an expected route, I accessed my Fedora 41 machine via XRDP and the drivers were loaded and functional with the following with GRUB_CMDLINE_LINUX set to “rhgb quiet” , when I connected via HDMI, it failed, I had a black screen but accessing remotely via XRDP, the driver is loaded and shows PITCAIRN and not software rendering, so I believe the issue is related to HDMI and detection of the correct display routes? I’m running Fedora 41 on a Trash Can MacPro 6,1 with dual D300 Firepro cards AMD/Radeon

9

Remote Desktop is probably using software rendering (via your CPU). That would probably work even if the computer didn’t have a GPU, so it wouldn’t be a reliable indication that the GPU driver is working.

Hi,
Definitely an issue with not detecting the screen size, I have a friend with a similar issue and he used this line in his GRUB to get it working “gfxpayload=text quiet radeon.si_support=0 amdgpu.si_support=1 video=1920x1080@60”, I can see the AMD driver loads and his screen works, I have also tried setting the video, the driver loads not PITCAIRN which is Radeon but AMD and I am still a black screen and I’ve tried 3 very different screens and cables (to be sure). I’ll post my dmesg output later
