And did you run 'fbset <anymode>' on first head after secondary head was registered? You have to... After bootup first head uses all 16MB for picture. When you load secondary head module, videoram is split 8MB for first head/8MB for second. And because of for correct checking driver have to scan all your VCs for picture size, and refuse to load if any resolution is over 8MB, I just decided to put this task on user - run 'fbset -a -depth 8' after you load secondary head module. It will shrink '-vyres' values for primary head displays from their current value to maximum value possible for new memory configuration. Petr Vandrovec vandrove@vc.cvut.cz
