Hi
Remove the nomodeset and reboot the system and see how it goes with the
default radeon driver.

thanks for the reply!
I tried this and it just goes blank nothing shows up on the screen, i even re downloaded and installed tumbleweed and still just goes blank after boot, ive been trying to figure out whats happened and im pretty sure its a graphics problem. im currently dualbooting with manjaro which is working fine using the same drivers.

Hi
OK, in manjaro can you post the output from;


uname -a
lspci -nnk | grep -A3 VGA

Then in openSUSE press crtl+alt+F1 to get to a VT, login and run the lspci command as above, then post the output back here (between code tags).

Hi
Ahhh hybrid graphics… so can you disable the intel or amd card in the BIOS?

7

ive disabled the intel graphics via bios and still blank screen

Hi
So what’s the output from the lspci command now, using the radeon or amdgpu driver? Battery consumption may be higher though, I think vgaswitcheroo is the tool for you;

well its now gone back to blank screen when booting, im not quite sure why this could be happening considering ive used other distros without this problem but tumbleweed just dosent want to work with my card

Hi
Maybe blacklist the i915 driver and rebuild the initrd? Else look at the vgaswitcheroo or what does the other distro show in grub (blacklisted i915?) etc?
