How to change my resolution to 1024x768

[carmelofranco]

Hi.. im new to linux and my problem is that i cant set my monitor resolution 1024x768, when i go to the configure display menù (KDE) i can only see two resolutions 800x600 and 640x480 =(


My video card is a trideo video accelerator (16mb) and my pc is a notebook toshiba satellite intel celeron 900mhz 128mbram


Thanks anticipate for the answers

High! Welcome to VectorLand.

To change the resolution, you need to edit xorg.conf as root. I am assuming you are using VectorLinux 5.9 STD

To login into root account, open up Terminal and issue command

Code:

su

input your root password.
Next up, backup your existing xorg.conf

Code:

cp /etc/X11/xorg.conf /etc/X11/xorgbackup.conf

Open xorg.conf with mousepad (or any other text editor you like)

Code:

mousepad /etc/X11/xorg.conf

A text editor should pop up. Find the section "Screen"
It should look something like this

Section "Screen"
Identifier "Screen0"
Device     "Card0"
Monitor    "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport   0 0
Depth     1
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     4
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     8
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     15
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     24
Modes "800x600" "640x480"
EndSubSection
EndSection

You'll notice that in the Modes lines there are resolutions. The listed resolutions are the ones the system is going to try.
Add "1024x768" to the every one of the Modes lines. So it should look something like this

Section "Screen"
Identifier "Screen0"
Device     "Card0"
Monitor    "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport   0 0
Depth     1
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     4
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     8
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     15
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     16
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport   0 0
Depth     24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

Make sure you add "1024x768" before the other resolution modes (from left to right).
Double check there aren't any typos
Save (Hit Ctrl + s)
Save your work, next one is gonna restart your X server and that means shutting down all apps.
Hit Ctrl + Alt + Backspace.

And then you should have your resolution set to 1024x768.

If by any chance you already have "1024x768" in the Modes lines, you will prolly need to adjust the proper refresh rates for you. In this case post your /etc/X11/xorg.conf here and we will continue.

Thanks for the help:)

Anyway... in my xorg.conf there are already that 1024x768... but i dont know how to post here that file cause i accessed in it with console as root.. with the help of file manager

There is a way for open that file with desktop boot?

Or maybe say me how to change my monitor refresh rate... now i have only 70herz and 75herz.. maybe i need lesser? like 60herz??

Thanks..

Ok.. i did it... now what i've to do??

Ok i posted it.. can you say me how to adjust refresh rates?

[nightflier]

The line to look for is the one which states:
VertRefresh 72-75

In your case X will try to drive it to 75 Hz if it can. Assuming your display is an LCD, you should be fine using 60 Hz. Try changing those numbers to 50-60.

After each change, remember to save the file, and restart X (or your computer). When troubleshooting X I always boot to TUI and use "mcedit /etc/X11/xorg.conf" for edits, then "startx" to test display.

[carmelofranco]

Ok i resolved my problem.. now im 1024x768.. thanks to all for the help

Cya boys!

[nightflier]

Great!   

Would you please tell us how you fixed it, so that others may benefit from this thread?
