  Hi, you can delete xorg.conf , all confs are now autodetect ,

 Ok, I've reduced my xorg.conf to the following:
 
 Section Device
 Identifier  Card0
 Driver  radeonhd
 EndSection
 
 Otherwise, the autodetect gives me the radeon driver, which doesn't work 
 well. I've commented out everything else. I still have the problem with 
 'pink screen' following resume from hibernate, corrected by restarting X 
 or rebooting, neither of which are convenient.
 
 Any other suggestions?

And unplug and plug monitor ?  or try disable and enable monitor with
xrandr --output VGA1 --off ? 

Don't know more to help you , sorry ! 

 Thanks,
 
 Tyler

 Details:
 I'm running Debian Testing on an HP Elitebook 6930p, with the xorg 
 version packaged by Debian, version: 1:7.4+4.
 
 I had previously had problems with getting the external monitor to work 
 at all following hibernate, which was corrected by adding the following 
 line to /etc/hibernate/common.conf:
 
 OnResume 20 xrandr --auto
 
 The default hardware detection in X used the radeon driver, which 
 produced a lot of flickering. I used the Debian tools (dpkg-reconfigure 
 xserver-xorg) to generate a xorg.conf file, which I then edited manually 
 to use the radeonhd driver, which seems to work properly.
 
 I've googled for answers, read the xrandr and xorg.conf documentation 
 (which I don't fully understand, I admit), and my xorg.0.log (also 
 mostly incomprehensible to me) but I'm not sure how to proceed.
 
 Any suggestions would be welcome. I've attached my xorg.0.log and my 
 /etc/X11/xorg.conf file.

Hi, you can delete xorg.conf , all confs are now autodetect ,
Driver  kbd
and 
Driver  mouse are deprecated. 

my xorg.conf, just change for my specifics , and not default options:
