No HDMI output with RV870/HD5770

[clesch]

Binary package hint: xserver-xorg-video-ati

Displays connected to the HDMI-out of my HD5770 show no signal using the “xserver-xorg-video-ati” package.

I was able to work around it by connecting my TV via DVI for the installation, installing fxgrl and then connecting the TV via HDMI again, but I would prefer to use the FOSS drivers rather than ATI’s proprietary drivers.

[madbiologist (me-again)]

You must be using userspace mode-setting (UMS), right? The UMS mode-setting code for Radeon HD5xxx series chips currently doesn't work well for digital outputs.

Unfortunately kernel modesetting (KMS) for Radeon HD5xxx series chips was only introduced upstream in kernel 2.6.34.

If UMS is the default then that is probably what I’m using, yes. I’ve also noticed that Monitors connected to the Displayport get no signal either, so of the four connectors on the card only the two DVI ports work with the FOSS drivers at the moment. All outputs work using the latest 10.4 Catalyst, however.
