Description Michael Hartman 2015-07-07 16:05:29 UTC

I am using the opensource radeon drivers with a radeon HD 6870.  

When I enable the use of glamor in my xorg.conf.d/20-radeon.conf

Section "Device"
	Identifier 	"vga"
	Driver		"radeon"
	###Option		"AccelMethod"		"EXA"
	###Option		"EXAVSync"		"off" 
	###Option		"EXAPixmaps"		"on"
	Option		"AccelMethod"		"Glamor" 
	Option		"RenderAccel"		"on" 
	Option		"ColorTiling"		"on" 
	Option		"AccelDFS"		"on" 
	Option		"SwapBuffersWait"	"false" 
EndSection

the text takes a very long time to display in xdvi and loads like a typewriter typing it out, computer is unresponsive until full page loads.


The problem goes away when I switch to EXA:

Section "Device"
	Identifier 	"vga"
	Driver		"radeon"
	Option		"AccelMethod"		"EXA"
	Option		"EXAVSync"		"off" 
	Option		"EXAPixmaps"		"on"
	###Option		"AccelMethod"		"Glamor" 
	Option		"RenderAccel"		"on" 
	Option		"ColorTiling"		"on" 
	Option		"AccelDFS"		"on" 
	Option		"SwapBuffersWait"	"false" 
EndSection
