ATI HD3400 in Lenovo T400: xf86-video-ati from testing docking issues
Hi everyone,
I have a Lenovo T400 which I exclusively use with the discrete ATI HD3400 graphics chip because I need the DVI output from my Lenovo Advanced Mini Dock to drive a large display. When I recently updated to xf86-video-ati 6.9.0.91-1 (from testing), everytime I start X and the laptop is in the dock, all that happens is that the whole internal screen shows one full-screen color, cycling white->red->green->blue->grey->vertical black/white gradient->horizontal black/white gradient, and the external DVI display is ignored. The internal display is fine when I start X in the undocked state, until I put it into the dock and enable the DVI-out via xrandr (VGA-out seems to work fine, curiously).
6.9.0-6 (from extra) shows no problems. Pity this happens right now that one can expect more from the open-source drivers due to AMD's publication of the hardware spec...
Has anyone encountered a similar problem or knows where to file a bug most appropriately?
Thanks in advance,
S.

Why don't you try the ATI binary drivers? Sure they aren't what we all would want them to be but at the current time they have support for more things than the open source drivers.

Do they support xrandr 1.2 now for using multiple displays easily? Last time I played around with them (in October) this was still a pain and ugly hacks were necessary to get multi-head to work. Otherwise I would have switched long before.
