That scenario is not supported and only happens to work by luck with
ums. Since the encoder is shared between the DIN port and the analog
portion of the DVI port, you can't really use them both at the same
time. It should work with the DIN and the VGA port.
Thanks, I'll try to remove DVI2VGA connector and plug monitor into
VGA. But there is interesting thing: I bought DVI2VGA connector while
experimenting with CRTC settings. :) It solves TV-out problem in UMS
mode.
Strange things with CRTCs<->output assigning...
I checked VGA, but still have no success with TV. Moreover it seems VGA
has issues with getting available modes. If I do xinit with or without
xorg.conf it sets improper frequencies. Easiest way I found is 60Hz
limit ('VertRefresh 40.0 - 60.0') however monitor can 75Hz and console
works in this mode. Probably I can set proper modeline to get 75Hz but
driver can not detect it automatically.
Full story below (hope it help clarify what happens):
~2 year ago I bought ATI HD3450 and wasted quite much time before I
catch that VGA and DIN can not use different CRTCs. Then I bought
DVI2VGA connector and TV works fine on CRTC#0, DVI on CRTC#1. TV was
broken after I switch to KMS.
May be TV has the same issue as VGA and I should make proper raw mode
with --newmode?
