I forgot to add the output of the xrandr command, which will likely be usefull:

I just found a workaround : after doing an "xrandr --output S-video --off", I can sucessfully activate the VGA-0 output. I obviously have no idea why it helps. All this might be related to bug #12230. Note well that I don't use the S-video output, and that nothing is connected to it. The fact that I have turn S-video off while it is marked disconnected, to have VGA-0 working is definitely weird. We do load detection on the tvdac for tv-out detection, however, it's not always reliable on all different chips, hence you get false positives on occasion. There is an alternate tv detection routine that seems to work better on some r3xx chips. you can try it by commenting out lines 1414-1414 in radeon_output.c
remove these:
if (IS_R300_VARIANT)
return r300_detect_tv(pScrn);
We may just have to turn off load detection by default for the tvdac.
lines 1413-1414 obviously. |
