Okay, it seems that overriding the vsync and hsync settings is useless in atyfb as it has its own algo to do that: if(vdisplay < 400) { h_sync_pol = 1; v_sync_pol = 0; } else if(vdisplay < 480) { h_sync_pol = 0; v_sync_pol = 1; } else if(vdisplay < 768) { h_sync_pol = 0; v_sync_pol = 0; } else { h_sync_pol = 1; v_sync_pol = 1; } I'll trim the patch for csync only. > - append="video=atyfb:1024x768@70,comp_sync:1" > Same results as first test. > > The sync settings were checked with 'fbset -i'. > > > BTW, the mode string should always be the last parameter, ie; > > > > video=atyfb:comp_sync:1,1024x768@70 > > Hmmm. Wonder why you say that (considering the result of my last test). My mistake then. Thanks for verifying. > > Should these new options also be documented in Documentation/fb/? I'll add this and fix a few buglets when I push upstream.
