Set my screen resolution to a higher resolution

yinglcs · #1 15th February 2007, 04:39 PM

Hi,

I install Fedora 5 on my laptop, but the graphic card it set is "ATI Technologies Inc Unknown device 7145". And I can only set the display to 800 X 600 (the highest available). How can I set it to a higher resolution?

Thank you.

Now wut you want to do is edit this line

Code:

Modes "800x600" "640x480"

and add in the resolution you want
here I put in the 1024x768 and the 1280x960 resolution

Code:

Modes "1280x960" "1024x768" "800x600" "640x480"

su into root then gedit /etc/X11/xorg.conf. add your resolution to the modes line.

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 16
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480"
EndSubSection
EndSection

so you have:

modes "1280x1024" "800x600" "640x480"

oops, sorry red wind. Didnt mean to step on your toes.

I'm having same trouble and I hope you guys can help me with this.

I am running Fedora 6 (32 Bit version) using VMWare Workstation 5.5.3

I can't go higher than 800x600
I know how to do this with Ubuntu but for some reason my xorg.conf looks lik eis missing lots of things. Here it is right from ect/x11

# Xorg configuration created by pyxf86config

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "vmware"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

Would you guys please help me add the missings lines I need. I want to go all the way up to 1280x1024

My monitor frequencies are:

H 31 - 80 Khz
V 60 - 75 Hz

im sorry but I cant help you with this one

I am having the same prob on my server
so someone else could jump in here

JN4OldSchool · #8 15th February 2007, 10:21 PM

well...I run 1280x1024 in my vmware distros but I have found they all are different in level of difficulty to force to do this. For starters though you need to add the line:

modes "1280x1024" "1024x768"

under the "depth 24" line in the screen section.

This will allow you to choose the lower res for the vmware window view or the larger for full screen view. Now, how you force FC to use the higher res i dont know. I have been successfull under most distros to change the display properties tab to a different monitor but this is all hit and miss.
