http://bugzilla.opensuse.org/show_bug.cgi?id=917385 --- Comment #7 from Stefan Dirsch --- (In reply to Dominique Leuenberger from comment #6)

Some more info:

* the system starts up with "nomodeset" passed to the kernel

Sure, In that case likely the non-KMS based cirrus driver instead of builtin modeset(ting) is being used.

* the system FAILS to start with "nomodeset x11failsafe"

So here you're trying to use modesetting driver without KMS enabled. Not the smartest idea IMO. Anyway, the issue here is. The builtin modeset(ting) driver now tries to use glamor for acceleration. Apparently this doesn't work during installation due to missing Mesa drivers depending on llvmpipe (huge deps to llvm libs). The fallback to ShadowFB fails as well. Culprit seems to be hw/xfree86/drivers/modesetting/driver.c:789 ret = drmGetCap(ms->fd, DRM_CAP_DUMB_PREFER_SHADOW, &value); For some reason this fails. So neither glamor nor ShadowFB acceleration (also known as acceleration "none"). More to come ... -- You are receiving this mail because: You are on the CC list for the bug.
