[Savage40] xv Overlay on crtc2 on SuperSavage (T23) / Argyll display calibration (Resend)

[Jon Senior]

Resent because I wasn't a member of the list last time so couldn't be sure if it was blocked (checking the archives didn't reveal anything coming up).

------------

I think the title says it all. ;-) Looking through the archives I notice that this got a mention as a known issue, but web searches only seem to produce hits dating from 2004/2005. Being as we are now in 2008 and this a device likely to lose rather than gain coders, I was wondering what the problem actually was.

The problem in question is that (as best as I can tell) it's not been possible to enable the overlay in crtc2.

There is also a related issue in that in crtc1 with working overlay, video with a horizontal resolution greater than 800 pixels (IIRC) shows pink gradient bars from the 801st pixel onwards. This is hard to demonstrate as screen grabs using xine / player show the correct video.

A final query: I was using the Argyll colour management suite to calibrate the internal display (It's not very good, but it's now a calibrated not-very-good!). Having added a second display (external CRT) and set up for xinerama calibration no longer works. I can run the software and generate profiles and using dispwin to load the profiles doesn't return any errors, but nothing actually changes on either display. Does xinerama on SuperSavage do something strange to the video LUTs? I ask because I got a similar effect when connecting an external display and using Fn-F7 to switch. The first press changed nothing, but unloaded the calibration settings.

Thanks in advance.

Edit (For resend): I had problems with the scrolling hang in xinerama, but adding Option "ShadowStatus" "true" didn't seem to solve it. Interestingly, adding that option to both Device sections killed xinerama and left me with only the external CRT which has perfect xv. I assumed the crtc's would be hardwired. If this is not the case, is there a way to specify which one gets used where? Is it just screen ordering? I could handle only having xv on the CRT when both are enabled. :-)
