Resolution in the KDM

The KDM greeter was showing a bad resolution I just commented the line
and added the red line in /etc/X11/xorg.conf

User Agent Switcher

This is a wonderful add-on for firefox that makes webpages believe that you are using in fact MS Explorer. This is really useful with some problematic webpages

Migrating from Fedora 4 to Ubuntu 7.10

I bought a new hard disk. And I installed Ubuntu 7.10 on it (/dev/hdb). Ubuntu did not want to recognize my partition where I had previously installed Fedora (/dev/hda3). I had to install

$sudo apt-get install lvm2

And then I followed the instructions on:

http://pissedoffadmins.com/index.php?entry=entry070507-105201

Now, just add at the bottom of /boot/grub/menu.lst the following lines to

title Fedora Core 4
root (hd0,1)
chainloader +1
boot

save the file and reboot! See this



To change the console font (when one gives Ctrl+Alt+F1) add the vga=771 to the corresponding line in /boot/grub/menu.lst. For example:

title Ubuntu 7.10, kernel 2.6.22-14-generic
root (hd1,0)
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=44d34aca-a862-4a4c-99b8-b2ba480527cb ro quiet vga=771
initrd /boot/initrd.img-2.6.22-14-generic
quiet

The table of resolutions is: from http://ubuntuforums.org/showthread.php?t=123920

Code:

                640x480 800x600 1024x768 1280x1024 1600x1200
---------------+-------+-------+--------+---------+---------
256 (8 bit)    |  769     771     773       775       796
32,768 (15 bit)|  784     787     790       793       797
65,536 (16 bit)|  785     788     791       794       798
16.8M (24 bit) |  786     789     792       795       799

I "installed the super user". To do this, I just did:

$sudo passwd root

And I assigned a password to root





I removed the NDIVIA logo at startup: Edit /etc/X11/xorg.conf and change the corresponding lines to:

 Section "Device"
...
Driver     "nvidia"
...
Option     "NoLogo" "true"
EndSection

The KDM has a keyboard configuration in English. But my keyboard has a german distribution. This makes it problematic to ingress passwords. To change the keyboard edit /etc/X11/xorg.conf and change the correponding line

Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "de"
EndSection


DO NOT run
$ sudo dpkg-reconfigure -phigh xserver-xorg
as it is recommended in the comments of that file!






To install the mouse in the console mode (Ctrl+Alt+F1) do
$ sudo apt-get install gpm
and then reboot the computer.

Commands

$ lspci with this command I can check for example which graphics card do I have

Adding Source list
you need to edit /etc/apt/sources.list file
sudo vi /etc/apt/sources.list
Add the following line for the latest beryl (Both i386&64 bit)
deb http://ubuntu.beryl-project.org feisty main
Save file and exit
Copy the key file using the following command
wget http://ubuntu.beryl-project.org/root@lupine.me.uk.gpg -O- sudo apt-key add -
Now you need to update the source list using the following command
sudo apt-get update

How to associate the Start key in KDE

Execute in console

$ xev

And obtain the corresponding info. Example:

eyPress event, serial 30, synthetic NO, window 0x3e00001,
root 0x60, subw 0x0, time 5783328, (-83,158), root:(594,323),
state 0x10, keycode 115 (keysym 0xffeb, Super_L), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

KeyRelease event, serial 30, synthetic NO, window 0x3e00001,
root 0x60, subw 0x0, time 5783427, (-83,158), root:(594,323),
state 0x50, keycode 115 (keysym 0xffeb, Super_L), same_screen YES,
XLookupString gives 0 bytes:


Execute in console (or put in .bashrc)

$ xmodmap -e "keycode 115 = F13" #esto es para que StartKey sea F13
$ xmodmap -e "keycode 91 = 46" #esto es para que la coma del teclado numerico, sea un punto

This is for making StartKey behave like F13

Now, in Control Center -> Regional & Accesibility -> Keyboard Shortcuts -> Global Shortcuts ->
Popup Launch Menu -> change Alt+F1 to F13, simply pressing the StartKey

DONE

Tricks for Maria
$ xmodmap -e "keycode 96 = minus" #F12 se vuelve minus
$ xmodmap -e "keycode 96 = underscore" #F12 se vuelve underscore
$ xmodmap -e "keycode 61 = space" #minus se vuelve space

Samba tips

Use

smbstatus to see who is connected in the samba network to my computer... and to see which file that person is actually checking.

Going from Fedora to Ubuntu

Instead of executing su, we have to execute sudo; this command will ask you a password. Just introduce the user password. If you want to be root you have to make
$ sudo su

Basically instead of yum we have another command, namely apt-get. Its use is as follows (more details executing $ man apt-get):
sudo apt-get install nameprogram
sudo apt-get remove nameprogram
sudo apt-get search nameprogram
sudo apt-get update nameprogram

examples:
$ sudo apt-get install thunderbird

$ sudo apt-get install ubuntu-desktop #do this if you are using kubuntu, to install gnome

$ sudo apt-get dist-upgrade #this command updates all the packages of the system

apt-get requires a list of the sources. You can edit it:
$ kdesu kedit /etc/apt/sources.list



Some other packages that are worth to install are:
adept, kpackage #those are similar to yumex
to execute:
$ kdesu adept

amarok
kdm libdvdread3 #I don't remember what is "kdm"
libxine-extracodecs

koffice
