Re: xorg video modes question

[Fred <fred@blakemfg.com>]

Hello,
I thought my xorg problems were solved but there is still a problem. 
Please see below.

Hi Hartwig, Mark,

The xorg.conf file fixed the problem.  I commented out the sections for 
the keyboard and mouse since the Sun keyboard and mouse worked ok.  I 
changed the other sections to suit the Sun LCD.

Thanks for the help!

Best regards,
Fred

The monitor is now running at 1280x1024.  I am using the openbox window 
manager.  The display is way bigger that the LCD and when an application 
is minimized the icon goes way off the screen and I can't get it back. 
Respondents on the openbox mailing list say this is an xorg problem. 
Openbox supposedly just uses whatever X tells it.  I added the "Virtual" 
line to the xorg.conf file but it didn't appear to have any effect and I 
don't see another option that might.
Here is the video portion of my xorg.conf:

# xorg.conf (X.Org X Window System server configuration file)

Section "Device"
	Identifier	"Configured Video Device"
        Driver          "ati"
	Option		"UseFBDev"	"true"
EndSection

Section "Monitor"
	Identifier	"Sun-x7205a"
	HorizSync	35-80
	VertRefresh	56-75.1
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Sun-x7205a"
	DefaultDepth	16
	SubSection	"Display"
		Depth	16	
		Modes	"1280x1024" "1024x768"
#		Depth	24
#		Modes	"1280x1024" "1024x768"
		Virtual	1280 1024
#xdm won't run if depth is set to 24
	EndSubSection
EndSection

Best regards,
Fred
