The patch has finally reached the debian repositories and now we can actually find a solution for this problem. I would like to explore with the solutions that you recommended here but I'm not sure how to proceed. Here is the questions that I have: Can we re-open the device without patching directfb? How can we avoid using a VT? I'm not too sure how the linux input driver is supposed to work. I do know that there is a note about the linux_input driver causing problems on somebody's system (line 1126 of splashy_video.c http://git.debian.org/?p=splashy/splashy.git;f=src/splashy_video.c;hb=HEAD): /* * I disabled these modules, because they were causing problems on my * machine. */ DirectFBSetOption ("disable-module", "linux_input"); Any help will be greatly appreciated.
