[Bug 556253] Re: [2.6.32-19 regression] Does not check lid status any more, blank screen

[Martin Pitt]

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
