Description Javier Ariza 2009-02-07 08:20:45 UTC

i have the last xorg.conf (witch ubuntu intrepid).
This bug is present.  I build this package from source too, and the problem persist.

I have a multiseat configuration.  All work ok. But when someone press Alt+FN or CONTROL+ALT+FN system switch to tty.

I added in my xorg.conf the DontVtSwitch, but appears don't work.
In some web pages i saw this entry is ignored if 
  Option "AutoAddDevices" "false"
  Option "AutoEnableDevices" "false"
exists in this file too.


I'm trying to patch the source code to ignore this keypress ALT+FN or CONTROL+ALT+FN, but i don't now exactly where touch.  There are some if (vtswitchenable && ...   ... )  , i added in all ( .... .. && FALSE).
Building and installing the package, but keypress aren't being ignored.
 The file interesting is xorg-server-1.5.2/hw/xfree86/common/xf86Events.c


My ServerFlags section in xorg.conf:


Section "ServerFlags"
  #These option keep the X Server from entering in power saving mode:
  Option "BlankTime"    "0"                                          
  Option "StandByTime"  "0"                                          
  Option "SuspendTime"  "0"                                          
  Option "OffTime"      "0"                                          

  #Allow the server to start without mouse
  Option "AllowMouseOpenFail"   "yes"

  #anadido javi:
  Option "XineRama"     "on"
  Option "AllowEmptyInput" "true"
  Option "AutoAddDevices" "false"
  Option "AutoEnableDevices" "false"


  #Disable VT switching with ALT+Fn
  Option "DontVTSwitch" "yes"
  # Option "HandleSpecialKeys" "Always"

  #This disallows the user of the control + alt + backspace sequence
  Option "DontZap"      "true"
EndSection

Please submit a patch for xf86Events.c or give me a hint.
I'm planning to mount some multiseat configurations, but this problem is giving me a headache. 

Greetings.

Please see ubuntu's bug report at https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/295195 where I reported it initially.

Cheers,

AFAICT, this seems to work in master, at least with the evdev driver. With
the kdb driver of despair (the 'fixed' version) it doesn't seem to VT switch
anyway.

well, not much yet (few hours), but as for VT switch I can't switch away nor kill Xorg in my multiseat setup on jaunty,
will test a bit more during the coming days, but looks just fine to me at the moment.

Cheers,
Mik
