Hi,
about two months ago I bought a Radeon HD 6570 with 2GB memory for my main computer and I have a single monitor connected to it, until now via VGA D-Sub.
Last week our secondary TV died (it was 15 years old, R.I.P.) so I bought a nice 32" LED TV which has 3 external HDMI connectors.
The HD 6570 has one DVI-D, one HDMI and one VGA connectors so I thought it would be fun to allow the family to watch videos while I can also work on the computer.
Here comes my problem: no matter which connectors I use for the monitor (DVI-D or D-Sub), if the TV is switched on, HDMI comes up as primary display. The result: GNOME 3 workspaces are switchable on the TV but a single workspace is visible on my monitor. This would be the perfect setup if I can reverse the roles of the TV and the monitor.
"man radeon" had an option which I tried but didn't help: Option "ZaphodHeads" "DVI-0,HDMI-0"
Is there any other option that does what I want?
Thanks in advance, Zoltán Böszörményi
