Correct me if I'm wrong, but ironlake has LVDS for the internal
display; eDP replaces it from haswell on. Either way, according to
the trace you're trying to use display 1, which is the VGA port, not
LVDS (cf. /sys/src/cmd/aux/vga/igfx.c:32 and
/sys/src/cmd/aux/vga/igfx.c:1143). If you're using a particular vgadb
entry, make sure it has "lcd=1"; that will select LVDS, ie. the
internal display. It's pretty confusing... Perhaps you could try
monitor=x60t, since that already has an entry for 1024x768 with lcd=1.
If it works, you should get something on the screen even if the
timings are wrong and it's distored or whatever.
Hope this helps,
