Description Christopher James Halse Rogers 2007-11-20 13:29:37 UTC 
On my laptop with a 7600GO, internal 1680x1050 LVDS LCD and external 1280x1024 single-DVI LCD connected.

Setting randr12 to true in xorg.conf results in no signal being sent to the external DVI monitor.  Instead, the laptop's screen goes a speckled purple which then bleeds into white, and messes up the colours at the console, too.

Restarting X without randr12 "true" works (but doesn't drive the external monitor, obviously), and fixes the console colours.

I'll attach the Xorg log for this session.

A couple of weeks ago I sent in a mmio trace of the nvidia driver initialising X with this setup.  Feel free to ask for it again.

I see one problem immediatly, i never expected a nv4x range card to have an output that only works on crtc1, i will fix this when i get the chance.
Comment 3 Maarten Maathuis 2007-11-23 01:35:56 UTC 
I was wrong about that (misread the log), but still i'll look into what could be the issue.
Comment 4 Maarten Maathuis 2007-11-25 03:32:55 UTC 
Give it another try.

Oh, darn.  It still doesn't work, with the same symptoms.  The above Xorg log is of my most recent failed attempt.
Comment 7 Maarten Maathuis 2008-01-17 06:05:10 UTC 
Any improvement?
Comment 8 Christopher James Halse Rogers 2008-01-17 14:54:21 UTC 
RandR12 now works fine, driving both my internal LVDS and external DVI monitor.  Marking as fixed.
