Configuration files (networking, screen resolution etc.): where?

[bahiby]

I just switched to Kubuntu from Fedora. In Fedora I used to edit configuration files from the command line. Now I have trouble to find the right files; for example: everytime I login to the desktop I have to change the resolution. This takes time I'd rather spend on other things. I found the settings in the file $HOME/.kde/share/config/displayconfigrc. Should I copy this to /usr/share/kubuntu-default-settings/kde-profile/default/share/config and /etc/kde3?
Besides I want to be able to turn off the eth0-network card (ie don't start the device at boot).
Anyone who can help out?

Resolution

/etc/X11/xorg.conf (xorg X Window System server configuration file). It is text file.

Section "Screen"
=> SubSection "Display"
==> Modes "1680x1050" "1400x1050" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"

Available resolutions (default first).

Also:

sudo dpkg-reconfigure xserver-xorg

Here is good page of sudo dpkg-reconfigure xserver-xorg:

I want to be able to turn off the eth0-network card

Have you tried System Settings > Network Settings > Disable/Enable interface ?

Re: Configuration files (networking, screen resolution etc.): where?

xorg.conf reads:

SubSection "Display"
Depth 24
Virtual 1440 900
Modes "1440x900@60" "1280x800@60" "1280x720@60" "1280x768@60" "800x600@60" "800x600@56"
EndSubSection
EndSection

Still, after every reboot the resolution is set to 1024x768. I wonder why.

About disabling eth0: I tried kdenetwork-manager, but this solution sustains only till the next reboot (the option 'start at boot' is marked out)

What kind of graphic driver are you using ?

Section "Device"
=> Driver ??

The driver is fglrx (Ati Radeon).
(restricted support...)
Could that be the problem?

Is this from repositories ? (Version: 8.37.6)


Hmm - there seems to be problems with fglrx and resolution:

Problem with screen resolution solved for the moment...
Thanks for your help. The trouble was in a personal configuration-file: $HOME/.kde/share/config/startupconfig where I found the resolution I used on the (old) laptop with Fedora... I marked those out (#).

Still have to find a solution for the network, though. After every boot I must first disable eth0 before wlan1 works properly.

Post your /etc/network/interfaces file for a review.

Re: Configuration files (networking, screen resolution etc.): where?

/etc/network/interfaces reads:

I edited the file with an editor, but still I have to manually deactivate both eth0 and eth1 and today I could only bring up (ie get a connection with the router) wlan1 after:

$: sudo /sbin/ifdown wlan1
$: sudo /sbin/ifup wlan1

I wonder why and would like to know if there are more files I could edit. In Fedora I could simply 'erase' an interface in the standard networkmanager.

Re: Configuration files (networking, screen resolution etc.): where?

Do you truly have static ip address for you Internet account?? Your router isn't configured for dhcp??

I'm using a Linksys WRT65G Wireless-G Broadband Router. Both cable and wireless. My router security is WAP and this is what my interfaces file looks like:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto ath0
iface atho inet dhcp

Everything works like a charm. I'm using KNetworkManager for managing wireless connection selections.

I prefer static since one of the pc's on the network (ie mine) needs to act as a virtual server (Xhost-connection). I had troubles to set up an Xhost-connection using dhcp.

Since I don't have a cableconnection at my workplace (needed for eth0) and the built-in wireless card (eth1) doesn't work properly (Acer InviLink with Broadcom-chipset, could be due to my lack of knowlegde), I use a PC Card (wlan1) that works flawless except thateth0 and eth1 start at every boot and I first have to disable these cards for I have a proper network connection.
If anyone knows how to turn off eth0 and eth1 permanently... (disable modules in the kernel)

K Menu | System Settings | Network Settings | Network Connections | Network Interfaces
Click Administrator Mode button.
Click on the Interface you want to disable and click the Disable Interface button.
