xf86-video-ati-6.9.0-117-g435cf7d gives me one blank and one powered down screen instead of 2x 1920x1200 desktop joy. I reverted commits in small lumps and around xf86-video-ati-6.9.0-107-g23c17c0 I got one display back - that is 1 display showing actual content, and 1 display not powered down but blank. I tried building the radeon driver that used to work (ubuntu-hardy 6.8.0-1) against whatever Intrepid ships, and that yielded 1 working screen and the other showing a low res clone of the working - fiddling with xrandr only makes it worse. http://programming.kicks-ass.net/sekrit/xorg.conf http://programming.kicks-ass.net/sekrit/Xorg.0.log-xf86-video-ati-6.9.0-117-g435cf7d http://programming.kicks-ass.net/sekrit/Xorg.0.log-xf86-video-ati-6.9.0-107-g23c17c0 (just for kicks I also tried the radeonhd driver, but that either shows me a clone of the left screen or a clone of the right screen, but never both)
Using xf86-video-ati-6.9.0-107-g23c17c0 DVI-1 seems to be the working screen, whereas DVI-0 is the blank screen. When I prod at it with xrandr, I can get DVI-0 to show the low res clone, similar to the 6.8 driver. I cannot seem to change the resolution. Switching it off works, switching it back on gives me two blank screens.
<airlied> peterz: try generating a log file Option "ModeDebug" "true" <airlied> I'll take a look tomorrow. <peterz> airlied: what section do I put that in? <airlied> device <peterz> airlied: for both git ids, or just the slightly working one? <airlied> slightly working will do.. <peterz> ok, will do and update the logfiles I linked to <airlied> remove the Modes "1920x1200" from the screen section also as a test <airlied> and possibly the horiz/vert limits. <airlied> in the monitor sections http://programming.kicks-ass.net/sekrit/xorg.conf-debug http://programming.kicks-ass.net/sekrit/Xorg.0.log-xf86-video-ati-6.9.0-107-g23c17c0-debug
I believe this was fixed in 69e445f7f2ebd299070e44457b434bbc28b7e05c
