Ubuntu 14.04 - LVDS only tux visible

Postby kruszi » Tue Jan 31, 2017 5:29 pm


What could be the issue if only the tux (four of them WBQ) are visible but no graphical interface is loaded? I have a LVDS connected, timing seems right. Writing 0 to /fb0/blank will display the console. My devicetree has been adapted (viewtopic.php?f=12&t=1368)
