Created attachment 18061 [details] xorg.conf I have a laptop in a cloned setup with an attached external monitor. Screen goes black for a second on the external monitor whenever opening a new program. I have an Intel 945GM video card. For some reason, it does DDC detection every time a new application is open (so every time a new app connects to the X server).The following lines are printed in the /var/log/Xorg.0.log EVERY TIME an application is launched: imi@orcl:~$ tail /var/log/Xorg.0.log -n 30 (II) intel(0): EDID vendor "SEC", prod id 17495 (II) intel(0): Printing DDC gathered Modelines: (II) intel(0): Modeline "1440x900"x0.0 95.44 1440 1504 1536 1744 900 903 906 912 -hsync -vsync (54.7 kHz) (II) intel(0): EDID vendor "SEC", prod id 17495 (II) intel(0): EDID vendor "SAM", prod id 549 (II) intel(0): EDID vendor "SEC", prod id 17495 (II) intel(0): Printing DDC gathered Modelines: (II) intel(0): Modeline "1440x900"x0.0 95.44 1440 1504 1536 1744 900 903 906 912 -hsync -vsync (54.7 kHz) (II) intel(0): EDID vendor "SEC", prod id 17495 (II) intel(0): EDID vendor "SAM", prod id 549 (II) intel(0): EDID vendor "SEC", prod id 17495 (II) intel(0): Printing DDC gathered Modelines: (II) intel(0): Modeline "1440x900"x0.0 95.44 1440 1504 1536 1744 900 903 906 912 -hsync -vsync (54.7 kHz)
