Hi, the behaviour is caused by the fact that console server sends its output to the output server (renamed fb server) which contains only text mode and serial output drivers. Pixel-based kfb driver is currently stand-alone DDF entity and does not even have a routine to render characters. In other words, you can either have compositor running on top of kfb, or console running on top of output. The combination of console and kfb is no longer possible.
In the original GUI branch, old fb server was eliminated, whole driver package was ported to DDF and both compositor and console could run on it (i.e. kfb had function to render both pixels and characters). During cherrypicking of GUI branch, Martin decided to keep the fb server with embedded text drivers for the console and made DDFized pixel-only kfb driver exclusive for the compositor. To support the scenario you are trying to achieve, kfb driver would have to be re-introduced into the output server. Also it would have to be ensured during configuration/compilation/initialization that DDFized kfb driver and legacy kfb driver are mutually exclusive.
