I have a somewhat similar situation, am trying to install on a VMware virtual machine.
everything seems to go OK until it tries to boot, it shows the boot screen but then it seems to hang,
pressing any of the arrow keys will switch from the graphic screen to the text screen,
the bottom line says “Started Purge old kernels.”, it take maybe 20 and then it
displays “Started Cleanup of Temporary Directories” it’s been there for about 30 minutes
and it’s still there.
Have you tried the ‘safe setting’ installation ? The idea here is to try to install with very conservative settings. After install is complete, one can then one by one remove the ‘safe’ settings.
Wrt a possible graphics issue, does your USB boot menu for openSUSE have the ‘nokms’ option under the video settings ? If so, have you tried that ?
It may not have nokms, and so it may also be possible to press ‘E’ ( < unsure > ) and then go into the grub2 boot menu and edit the appropriate line adding ‘nomodeset’ and boot. Or instead edit the appropriate line and add " radeon.modeset=1 ".
The philosophy behind the above graphics suggestion is a speculative assumption that there is a problem with the graphics, and by using ‘nokms’, or ‘nomodeset’ or ‘radeon.modeset=1’ one is trying to not rely on the automatic kernel mode setting (kms).
Unfortunately, there is no option for nokms (although I couldn’t find anything to open up any video settings).
I added the nomodeset to the boot line and the process got past the splash screen and tried to start the connection managers, but it then hung after printing the following:
OK ] Started /etc/init.d/boot.local Compatibility
Tried the radeon.modeset=1 and using the onboard graphics but had the same issues. I think my next step might be to wait until Gigabyte turn the current Beta BIOS release to stable and try with that. Unless anyone can suggest something else?
“Started cleanup of Temporary Directories” too for me. After 2h15m, the drive light stopped blinking. After 10 min of quiet I restarted and saw “Automatic Configuration” and it looks okay now. I had started with new partitions done with Gparted.
