Well, the virtual hardware simply has no dpms support, except maybe for cirrus which mimics physical hardware. bochs could toggle the blank bit in vga register space. virtio and qxl could unmap the plane, but that might have unwanted effects on the host side because qemu thinks the guest turned off the display altogether. > For the fbcon issue, can we perhaps just unconditionally ask fbcon to > clear the screen when blanking?

I've seen this on real hardware too btw (arm board with non-working dpms). cheers, Gerd _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
