For my 'xmonad-session' I use a bunch of scripts to easilly get needed monitor setup for my dual head laptop graphic card.
$ l bin/xrandr-* bin/xrandr-bigdesktop -> xrandr-bigdesktop-LVDS_DVI bin/xrandr-bigdesktop-DVI_VGA bin/xrandr-bigdesktop-LVDS_DVI bin/xrandr-bigdesktop-LVDS_VGA bin/xrandr-bigdesktop-VGA_DVI bin/xrandr-clone-LVDS_DVI bin/xrandr-clone-LVDS_VGA $ cat bin/xrandr-bigdesktop-VGA_DVI #!/bin/sh xrandr --output LVDS --off xrandr --output HDMI-0 --off xrandr --output VGA-0 --auto \ --output DVI-0 --auto --primary --right-of VGA-0
Symlink 'xrandr-bigdesktop' is my default ... that is my laptop display is turned on and it is primary one and if something is connected to DVI-0 it would be used as secondary monitor. This symlink is called from my 'xmonad-session' startup script called by CDM in my case, so after boot I got LVDS_DVI setup (if there is nothing physically connected to DVI-0 I got properly just one monitor laptop LVDS setup, xrandr command will not fail and xmonad later starts correctly in 'one monitor' layout).
In office I've got 2 external LCD monitors so my preffered layout there is 'bin/xrandr-bigdesktop-VGA_DVI'. After I start my default LVDS_DVI session I just run in the terminal:
$ xrandr-bigdesktop-VGA_DVI && xmonad-session-repair
~/bin/xmonad-session-repair
#!/bin/sh xsetroot -solid black #nitrogen --restore killall trayer trayer --edge top --align right \ --width 10 --widthtype request --height 19 --heighttype pixel \ --SetDockType true --SetPartialStrut true \ --transparent true --alpha 0 --tint 0x000000 \ --expand true & xmonad --restart
When I need to move e.g. to meeting room I usually just grab my laptop and run :). So after that I have just dead laptop screen. What I do? I switch to some tty let's say first one Ctrl+Alt+F1 and then after I login and not forget to put myself into console in CDM menu I do:
# to be able to communicate with X server $ export DISPLAY=:0.0 # because CDM doesn't load profile $ . .profile $ xrandr-bigdesktop-LVDS_DVI xrandr: Configure crtc 0 failed xrandr: cannot find crtc for output LVDS # let's try sleep first for couple of seconds # in meantime switch to xtty (usually it would be 7th = Alt+f7 but depends how you're starting X server) # and wait... until your LVDS is back $ sleep 5 && xrandr-bigdesktop-LVDS_DVI
I've configured some xmonad key bindings so I don't have to do anything above manually.
-- xrandr ((myModMask, xK_F10), spawn "xrandr-bigdesktop-LVDS_DVI && xmonad-session-repair"), ((myModMask, xK_F11), spawn "xrandr-bigdesktop-LVDS_VGA && xmonad-session-repair"), ((myModMask, xK_F12), spawn "xrandr-bigdesktop-VGA_DVI && xmonad-session-repair")
Thank you! I don't know why I didn't find this post sooner (believe me, I looked!) You just helped me *so* much. :-) I combined your solution with this approach to handling status bar widths as percentages [0].
