freemangordon: so what dose compositing accelration in xorg do exactly
<buZz>
uvos: i'm trying to find if hdmi -and- lcd on could work
<uvos>
sure ofc
<uvos>
not just in theory it works in fine in practicce
<buZz>
because when i enable hdmi, the lcd turns off :P
<uvos>
just hildon dosent know what to do with it
<uvos>
no its just black beacuse hildon freaks out
<uvos>
it works fine with plain x
<buZz>
ah, maybe i shouldnt add --primary?
<uvos>
dosent help
<uvos>
hildon dosent know about that
<uvos>
this is use other window manager teretory
<buZz>
hmhm
<uvos>
freemangordon: while compositing x dosent really render anything, i though it was something about accelerating the offscreen buffers but idk.
<buZz>
but with just mirroring?
<uvos>
cant do that either
<buZz>
n900 can :P
<uvos>
since the dsi pannel can do one resolution, and one reslution only
<buZz>
yeah thats fine
<uvos>
and its unlikey the external montior can do the same resolution
<uvos>
so its unlikely to ever work
<uvos>
the n900 works entirely differently
<uvos>
it dosent have 2 display outputs at all
<buZz>
you can display a 960x560 buffer on a 1280x720 screen though :P
<uvos>
its just a dumb converter chip that drives the tv out
<uvos>
buZz: the mode has to line up
<uvos>
often the montiors will accept other scann rates thatn edid tells xorg
<uvos>
but you have to add a custom modline for that
<uvos>
never tried it
<uvos>
but that could work
<buZz>
hmhm
<uvos>
so the way that would work
<buZz>
well one of my hdmi 'tvs' is just a capture unit ;)
<uvos>
is use cvt to generate a modeline
<uvos>
then add the modeline to the crtc using xrandr
<uvos>
and activate it
<uvos>
then you can mirror the internal display to that
<uvos>
and kill hildon
<buZz>
hmm :)
<uvos>
should work if the external display accepts the scann rate (not guarenteed)
<uvos>
the other thing that might work
<uvos>
is to use a native resolution on the external display and add a xorg (xrandr --output --transfrom <matrix>) transformation matrix to the output to match the effective resolution to the one of the internal display
<uvos>
but that will only work if the ddx supports transformations
