- Add plymouth-renderers-Do-not-assume-all-keyboards-have-LEDs.patch:
Plymouth does not recognize keyboards without LEDs. This leads to
a NULL-pointer deref in the input code. Fixed by this patch. The
change is commit 709f21e8 ("renderers: Do not assume all keyboards
have LEDs") in the upstrema tree. (bsc#1233532)

Subject: force fb for cirrus and bochs, force drm otherwise
|
|
References: bsc#888590, bsc#980750
|
|
|
|
DRM does not work well with cirrus and bochs (no display) but the framebuffer driver
|
|
prevents DRM drivers from loading.
|
|
As we need to support cirrus for libvirt and bochs for QEMU, we cannot just remove support for frame-buffer.
