Can't load after changing video card

Opensuse Leap 42.3
My PC with a Nvidia video card was broken and I am trying to boot from another desktop with radeon video card
I only see GRUB at the boot and black screen after

Model of radeon card? Why does the scrren shot show openSUSE 13.1?

Had you installed NVIDIA driver?

If so boot using nomodeset

At boot screen press 3 fined line starting linux and add nomode set to end F10 to continue I think that worked in 13.1 maybe buyt maybe there is a line at the bottom of the boot screen you can add perimeters just type nomodeset there. I forget when things changed and 13.1 is seriously old. In any case if it boots to nomodesett mode remove the NVIDIA driver

Model AMD Radeon HD 6570
on screen it shows 13.1 because it remained from update
NVIDIA proprietary drivers are installed

How do I boot using nomodeset? It hangs with a blank screen on startup

I am switching from ASUS AT3IONT-I with Intel ION CPU with build in Nvidia video card to ASUS M2N32Sli Deluxe with AMD Athlon II X4 640 CPU
Finally could load on Nvidia. What should I install to be able to boot on ASUS M2N32Sli Deluxe with AMD Athlon II X4 640 CPU?

At the grub screen you can edit boot parameters on the fly by pressing ‘e’ to open the text-based grub editor. Use the arrow keys to navigate to the line starting with ‘linux’ (or ‘linuxefi’ if using EFI boot). Add ‘nomodeset’ at the end of the boot parameter entries. When done press F10 to boot, or ESC to discard edits and return to grub menu.

Documented here as well…

Make fresh install.

Or try to find working parameters through testing grub


Configuration that enables proprietary NVidia drivers usually blocks use of all FOSS drivers, including any required to run an AMD GPU. Likely the NVidia driver installation already blocks KMS, making nomodeset on kernel cmdline inert.

Kernel 4.4.138 looks like a 42.3 kernel.

The HD6570 should automatically run on the default modesetting DDX or the Radeon DDX once the NVidia driver installation has been completely reversed.

I would just recommend removing that parameter altogether.

Pressing ‘e’ makes blank screen with a blinking cursor only, nothing to edit
Will try to remove NVidia proprietary drivers

Update: the system is Leap 42.3 kernel 4.4.138-59

I’ve adjusted the prefix to ‘OTHER VERSION’ now that we know what Leap version you’re using. Of course you are best advised to upgrade to a current supported openSUSE version.

Thank you very much

Removed Nvidia proprietary drivers, nothing changed

It’s entirely unclear to me what works or not at this point. If you boot to the Grub menu, does pressing E produce a black screen no matter how long you wait after the strike? How were you able to remove the NVidia drivers if you only had a black screen? Are you sure you followed the removal instructions exactly? If you didn’t, there could remain a modified library required for any FOSS driver to work correctly, if at all, necessitating reinstallation of the package that provides it.

Are you now only getting the black screen when X is supposed to be running, and able to login on any of vttys 2-6 reached by Ctrl-Alt-Fn?

I repaired the broken system with NVIDIA and booted to KDE, removed drivers using YaST. Not sure if the old hardware will last long, want to move the SUSE system to another desktop with Radeon. What should I do?

Replanting NVIDA card now should work the NVIDIA driver was your problem

Can’t replant the video card, it’s build in the motherboard. I need to prepare a system to load with radeon card. What should I do?

How old is the Radeon? If neither ancient nor latest available, you may need to do nothing but move the disk and reconfigure network to use the new NIC. If you know the exact Radeon model, a more detailed recommendation might be possible. X automagic works very well for most configurations. NVidia is the largest exception.

NVIDA chip on the main??? Can you turn it off in the BIOS??
