I am having difficulties making merged framebuffer work in non clone mode. Below is the relevant tidbit from my xorg.conf file. Section "Device" Identifier "Videocard0" Driver "radeon" BusID "PCI:1:0:0" Option "MonitorLayout" "LVDS,CRT" Option "MergedFB" "true" Option "CRT2Position" "RightOf" Option "EnablePageFlip" "true" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1920x1200" Virtual 3520 1200 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Videocard0" Monitor "Monitor1" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1600x1200" Virtual 3520 1200 EndSubSection EndSection I'm using xorg-x11-6.8.1-22 The logs show that i'm running in clone mode. (II) RADEON(0): Running MergedFB in Clone mode, Radeon Pseudo-Xinerama disabled Any help is appreciated. Thanks.
