Hmm, drm.debug=0x04 under Karmic gives
[ 0.000000] Unknown boot option `drm.debug=0x04': ignoring
I might need to add that after the --, I'll play around with this a bit. But even without this, the karmic kernel is already quite verbose:
[ 5.280551] [drm] TMDS-14: set mode 1280x1024 27 [ 5.545646] [drm] LVDS-8: set mode 1280x800 28 [...] [ 98.874965] [drm] TMDS-14: set mode 1024x768 2a [ 99.382981] [drm] LVDS-8: set mode 1024x768 2b
This still exhibited the broken behaviour which the mentioned lid checking patch was fixing, i. e. both monitors got the wrong mode.
I also noticed that with lucid's -19, the VTs/plymouth are in fact working on the DVI, just X switches them off.
As a summary, these are the behaviors:
Karmic (2.6.31): - LVDS: 1024x768 (non-native), switched on in both VT and X - DVI: 1024x768 (non-native), switched on in both VT and X
Lucid 2.6.32-18: - LVDS: switched off in both VT and X - DVI: 1280x1024 (native), switched on in both VT and X
Lucid 2.6.32-19: - LVDS: 1280x800 (native), switched on in both VT and X - DVI: 1280x800 (non-native), switched on in VT, switched off in X
