Fedora Core 9: Screen Resolution can not change from "800X600" to "1024X 768"

csoftvietnam · #1 17th August 2008, 04:02 AM

hi every body! Sorry about this dump question.

I've installed Fedora 9, but I get mistake about resolution. Now, my computer only has two resolutions, that's : 640x480 , 800x600. Go to "System -> Administration -> Display", I can't see higher resolution, example 1024x768... Can you help me change resolution to higher 1024x768.

Thanks, best regard.

Look at the "Hardware" tab under the same menu you looked at..choose a generic CRT if you have a CRT type monitor or LCD monitor of that display resolution...click "OK"..go back to the first tab and see is that res is available..if not exit it and restart the X server (sometimes necessary..sometimes not).....CTRL/ALT/Backspace and log in again...and go the the display setting GUI again and see if that higher resolution is available now.

Hi, i got the same problem of changing the screen resolution more than 800x600. I checked the hardware>screen resolution, the maximum resokution in that drop down list is 800 X 600. Is there any way to change the resolution to 1024 X 768 ?? i tried changing xorg.conf file also.

I'm posting the xorg.conf file after editing.

This is all wrong. Copy-and-paste (as root user) with changes:

Code:

# Xorg configuration created by system-config-display

Section "ServerLayout"
	Identifier     "single head configuration"
	Screen      0  "Screen0" 0 0
	InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "Mouse0" "CorePointer"
EndSection

Section "InputDevice"

# keyboard added by rhpxl
	Identifier  "Keyboard0"
	Driver      "kbd"
	Option	    "XkbModel" "pc105"
	Option	    "XkbLayout" "us"
EndSection

Section "InputDevice"

    # generated from default
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "auto"
        Option      "Device" "/dev/input/mice"
        Option      "Emulate3Buttons" "no"
        Option      "ZAxisMapping" "4 5"
EndSection

Section "Files"
        ModulePath   "/usr/lib/xorg/modules"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "nv"
EndSection

Section "Monitor"
	Identifier "E70f"
	HorizSync 30.0 - 70.0
	VertRefresh 50.0 - 150.0
	Option "DPMS"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "E70f"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1024x768" "800x600"
	EndSubSection
EndSection

Try those changes. If that doesn't work, we'll try something else.

P.S. I have nvidia 6150 LE integrated graphics.

Hi Hlingler,

Thanks for taking time and helping me out. Its working now. Fedora 9 looks very cool in that resolution. Its my first time installing linux.

Thanks Again.

i got another problem, i Installed Avant Window Navigator and deleted the default KDE panel after installing AWN. I didn't like the AWN and i want to restore to default KDE panel. Can you help me how to get the default KDE panel back and uninstalling AWN.

Thanks.

Simply un-install the Avant Window Manager using the same method that you used to install it. To restore the default KDE panel: right-click on any open area/field of the desktop, and select "Add Panel" from the context menu. After you replace the panel, you will then have to add all of the applets and such again (right-click on the new/restored panel, and select "Add Widgets").

@gibz85: I have no idea what you are referring to. Use of the nvidia-settings utility is not recommended. See my NVidia How-To (link in signature). Please clarify.
