Linux 4.x QXL 64-bit kernel modesetting breaks 32-bit X.Org
With Linux 4.x we get KMS for QXL enabled by default. But then, when mixing a 64-bit kernel with 32-bit userspace, X.Org fails to start and says something like: “failed to set DRM interface version 1.4: Inappropriate ioctl for device”.
- booting with the 32-bit kernel (I’m starting to really want #8183 (closed))
I’ve tried a local xserver-xorg-video-qxl 0.1.4-3~bpo8+1 backport, but it did not help.
