Screen resolution limited to 800x600


I installed kubuntu 8.10, with KDE, On my machine with a KDS VS-7e monitor. While the montior can utilize a much higher resolution, in the KRandRtray program it wont allow it to go past 800x600 resolution.

Some of the stuff I looked up seems to indicate I will need to manually update the xorg.conf file as this monitor isnt supported for the automatic configuration.

Here is the current file:

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Here is what I was going to change it to:

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Monitor0"
VendorName "KDS"
ModelName "VS-7e"
HorizSync 30-70
VertRefresh 50-120
EndSection

Section "Screen"
Identifier "Screen0"
Device "Configured Video Device"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768"
EndSubSection
EndSection

(I went to the KDS site and got the specs for this monitor)

Question 1:
As a newbie, am I headed in the right direction and are the changes correct? If not, what should they be?

Question 2:
I can't seem to save the changes in KATE, because I dont have the rights? So how do I open this file so I can save it correctly?


Thanks for the help.

1. Yes, any screen problems will deal with the xserver, and the config file is /etc/X11/xorg.conf. I'm not quite sure how to change resolutions though.

2. It probably is because you don't have permission. You need to run KATE as root with :

Code:
kdesu kate
then type in your root password


good luck,

Your problem is most probably because you don't have the needed drivers for your video card, and you are stuck in low graphics mode. In that case, changing your xorg.conf won't help and can actually leave you without graphics at all.

To get more info on your hardware and modules that are currently loaded in the kernel, run the commands 'lspci' and 'lsmod' and paste the output you get back to the forum.

Udi is quite right. It looks like you used some sort of automatic configuration routine and Kubuntu wasn't able to guess your video card and left it empty. You are then stuck with a minimalist type configuration. You need to select a proper driver for your video card and reconfigure xorg-xserver.
cheers,
jdk

You need a nVidia driver. I never installed it myself because I don't have such hardware (I don't have Ubuntu either) but you should follow the instructions found in the Ubuntu web site:
