hello,

after last update of steam, every time i start steam my monitors will be swapped around

heres my normal layout: https://dl.dropboxusercontent.com/u/28788188/ss_27022014_21.27.40.png

i do have third one also but its mostly turned off.

anyway if i start steam, they switch places and thus messing up all on my desktop as well.
have to manualy put them back into correct order

nvidia drivers 331.49
Arch Linux x86_64 up to date

hmm it might be the issue that its reading xorg.conf metamodes at startup and doesnt respect the layout set currently.
my xorg metamodes basicaly cover all 3 monitors (1 is tv), 1920x1080 + 1280x1024+1920x1080
but when my TV itself is turned off, it will be detected as 800x600 only, cause no correct info recieved when TV is off.. that might mess things up.
i also got that monitor order switch when i was going into Steams "System Information"

gonna do some more testing

ok.. it seems that steam somehow checks metamodes.
i had to delete my TV from the metamodes lists from xorg.conf file.
somehow starting up steam switches to other metamode which has my tv enabled, but when my TV is not turned on its detected as 800x600 instead of 1920x1080 ..and thus it switches displays around... pretty nasty.. why does steam do that..i have no idea.

to reproduce the issue:
-plug in 3 monitors (2x dvi, 1x hdmi)
-have their order different than their order by videocard ports
-save X config file from nvidia-settings after you have changed the order to your liking
-reboot system (restart X)
-start steam and watch it switch monitors back into the plug order from video card, not the ones nvidia-settings reports

edit: SDL1x games seem to do same thing with it.. switching them around after you start up a game.. SDL2.x games do not

Games that do that (tested): Killing Floor, Serious Sam 3,

perhaps a nvidia driver issue? but weird that it started right after steam update...
