Currently running AMD RX460 gpu along with amdgpu-pro drivers.
A while back I ran into problems after updating the system. Leap 42.2 would not boot, and I was presented with a blank screen, with no prompt. After a lot of experimenting I found that booting to an earlier kernel (in boot options) enabled a full desktop once again. I continued to install updates over recent weeks until the blank screen reappeared, and boot froze. Using snapper and booting many snapshots, I found a workable system from late February, that reliably booted.
With the snapper rollback feature, this snapshot is now default. Any ideas on how to proceed from here? Should I continue to update? Can I retain this snapshot and experiment with the newer (kernels) and (updates).
Just to conclude… I have resolved to wait until we have better amdgpu software. The driver is installed and working, but any attempt to update my system causes a boot failure (blank screen). No command line is available. Being able to install security patches would be nice but I am wary of breaking my system and the large amount of time required to restore it. Snapper has been good during this process. I commend the Suse team for implementing this valuable tool. Being able to select previous snapshots and boot into them has been invaluable.
Just for practice I have renamed my working snapshot for easy identification in the snapper boot options.
One thing I found with my installation of snapper. Any attempt to use snapper on the command line was met with this error
“Failed to set locale. Fix your system”
I had to use the command “export LANG=en_US” to overcome this. Yast2 seemed to have all the required country and language settings - so not sure why this error occurred.
