Thinkpad T60 how to use projector/extenal screen with Fn-F7

Re: thinkpad T60 widescren, fn + F7 doesn't work for external monitor or projector in linux

I have fn-f7 working on a regular T60. I have ATI's fglrx driver version 8.35.5, thinkpad-acpi version 0.14-20070428, and kernel version 2.6.20 installed.

• You can't use tpb to get this working. You have to use ACPI.

Check out this page to figure out how to do that:

http://www.thinkwiki.org/wiki/How_to_get_special_keys_to_work

Once you are catching the ACPI event corresponding to a fn-f7 press, you need to associate that with some kind of script that uses aticonfig (comes with fglrx driver) to detect and switch monitors. aticonfig --query-monitor will print a list of the monitors currently connected and enabled, e.g.

aticonfig --query-monitor

• Connected monitors: crt1, lvds Enabled monitors: lvds

tells you that the external monitor (crt1) and the laptop screen (lvds) are connected, but only the laptop screen is being used. You can use aticonfig --enable-monitor to enable and disable different monitors, e.g.

aticonfig --enable-monitor=lvds,crt1

enables both the external monitor and the laptop screen.

Hope this helps.
