Thanks,
I'm sure I tried to address this before and there was something more to
it, but I'll give it a go. To be honest, I was satisfied with Xfbdev,
so I didn't try too hard to get it working.

Looks like this is just an oversight in the fbdev driver. Care to try a
patch?

Dropped kdrive == fbdev regression
Since kdrive, in particular Xfbdev has been dropped, this has left a hole in support for MONO (1bpp) framebuffer devices. I've been using Xfbdev for a picolcd mono matrix device for a few years. The Xorg fbdev driver only supports a minimum of 8bpp framebuffer formats which wasn't a problem given the existance of Xfbdev, but now leaves a whole class of hardware unsupportable. signature.asc Description: This is a digitally signed message part ___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
