Hi, I have a 2011 mac mini, which runs arch linux and works amazing. I have the monitor connected by hdmi, but I want to turn on a second monitor. a vga adapter comes with the mini mac to pass through ieee 1394 or firewire. Install the drivers from both the standard and extra repositories now. but it doesn't detect the monitor. I figure out what the problem is, but I don't know how to start to solve it. thanks for any help...
Sorry, I made a serious mistake, it was not the ieee 1934 port but the thunderbolt I will create a new post, with the correct data.

ieee 1394 or firewire
IEEE 1394 /is/ firefire (resp. firewire is Apples marketing brand of it)
drivers from both the standard and extra repositories
What "drivers" would that be? There're couple of in-tree firewire modules, none seem to deal w/ VGA converters.
it doesn't detect the monitor
Run
dmesg -w
and plug the adapter, post the output it generates.

Seth, thks for your response.
IEEE 1394 /is/ firefire (resp. firewire is Apples marketing brand of it), yes, yes, I know.
drivers from both the standard and extra repositories <-- do not install vga drivers, install: libraw1394
dmesg -w | grep 'firewire'
the output.
[ 1.325860] firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x2
[ 1.846213] firewire_core 0000:05:00.0: created device fw0: GUID 003ee1fffe6e4ac2, S800
when i disconnect and reconnect the adapter it does not generate new messages.
I think it doesn't read that a vga signal is coming...
Thanks

libraw1394 is an api. Unless you are writing your own software to access the monitor over firewire, then that is not relevant.

Please use code tags, https://bbs.archlinux.org/help.php#bbcode
Also nobody told you to randomly grep dmesg, that's not helpful at all.
