External Monitor Display with Mandrake 10.0 on Dell D600 Laptop

OK Gang,

I'm new to Linux. "Baby's Breath" new. I've setup a dual boot configuration of XP Professional and Mandrake 10.0 on a Dell Latitude D600 laptop. I'm unable to set a resolution that is compatible with my external Optiquest V115 monitor. Whenever I dock my machine (I'm actually using a port replicator), power it on and boot to Mandrake, the resolution and screen size is CRAZY HUGE! When checking the hardware configuration and selecting my monitor type from the list, I'm unsuccessful with establishing a working display. And of you gurus out there have any suggestions? Oh yeah, keep in mind that I'm new to this!

Just to notice that I have the same trouble with same laptop and mandrake 10

Also that the DEL600 have an ATI Radeon Mobility 9000 card .... is it a driver trouble ?????

I too have this problem since 9.2. my laptop is 1400x1050 yet ext monitor is 18" tft 1280x1024. 10.0 always tries to put 1400x1050 on to the ext montoir meaning i have to move the mouse around the edges to see whole screen! i cant use 10. its tooooo annoying,. how did it go wrong. it used to work in 9.1 and 9.2. i cant find any solutions on google etc and have given up on mandrake. until they can sort petty things out like this.

where is the multi monitor thing like in xp. i know i know XP bla bla. but there isnt an option to state laptop off ext moniotr On or set resultion. Once again it comes back down to drivers, the perenial problem of linux.

I will help yall with this because I spent all day today and part of yesterday trying to figure it out - and I eventually started to FULLY understand how the Xserver works, where its logs are located, what is in the logs, how the drivers work after chasing antiquated driver options.

You guys using ATI cards - need to read the manuals for the X driver for your video cards

For "Radeon" users, open /etc/X11/XF86Config with a text editor like gedit or vi (note - this works for Xorg too)

this is the file that has all your video card and monitor cofiguration information

there should be a section in XF86Config entitled "Device"

this section lists your video card's driver- if you have a card that is supported by XFree86 and it is configured properly

it should look similar to this
Section "Device"
    Identifier  "radeon"
    Driver      "radeon"
    VideoRam    32768
    Option	"AGPMode" "4"
    Option	"AGPSize" "64"
    Option	"AGPFastWrite" "1"
    Option      "EnablePageFlip" "on"
    Option "MonitorLayout" "CRT, NONE"
    BusID       "PCI:1:0:0"
this is the line you are missing Option "MonitorLayout" "CRT, NONE"

Option "MonitorLayout" "string"
This option is used to overwrite the detected moni-
tor types. This is only required when driver makes
a false detection. The possible monitor types are:
NONE -- Not connected
CRT -- Analog CRT monitor
TMDS -- Desktop flat panel
LVDS -- Laptop flat panel
This option can be used in following format:
Option "MonitorLayout" "[type on primary], [type on
For example, Option "MonitorLayout" "CRT, TMDS"

Primary/Secondary head for dual-head cards:
(when only one port is used, it will be treated as
the primary regardless)
Primary head:
DVI port on DVI+VGA cards
LCD output on laptops
Internal TMDS prot on DVI+DVI cards
Secondary head:
VGA port on DVI+VGA cards
VGA port on laptops
External TMDS port on DVI+DVI cards

The default value is undefined.

justletmein-there is an option for flat panels "TMDS"

you guys have the ati radeon 9000 card - if you would like to fix this monitor problem and add 3D support so that you can play games please do a search for flgrxconfig on google or here in the forums and you will see plenty of instructions on how to install it- its a config program which comes with an updated driver for your video cards and the config program will give you the option of setting your primary display to a CRT(a monitor) or a FLATPANEL ( justletmein take note) or whatever

hopefully this will help others looking to add an external monitor to a laptop with a radeon chip since google has zero friggin hits

Good luck mr murdahh
