OK so second time playing with the new Pi. First one was to get it all installed and check everything worked. Passed that.

Tonight it was work through the tutorials in LXF159 and 160

1st issue: I don't know the root password. Haven't found it in the articles but if I want to start GParted from the menu it asks for it. I know I could sudo from a terminal but I like having a root password. Is there one set up or shall I add the user root?

2nd issue: I don't have /boot/config.txt for fixing the overscan issue. As I installed from LXF159 have you used some other distro for the tutorial?

Cheers

John

Been onto the Pi website and found the answer to the root password problem

So just the missing config.txt to sort out (for the moment anyway!) Laughing

yeah sorry mate. Mea culpa, Bloody bad manners of me Embarassed

Issue#1: Root password
By default there is no root password

Options are:

A) set global sudo - in a terminal type "gconftool-2 -\-type bool -\-set /apps/gksu/sudo-mode true"

B) instead of logging in as a user at the first terminal screen, log in as root. At the terminal prompt type "sudo su" and then "startx" X11 runs as root and won't ask for root passwords

C) Set a root password. In a terminal type "sudo passwd root"

Issue#2: Missing config.txt
By default this file is not there.

Create one by typing in a terminal "touch /boot/config.txt"

This can be populated by reading the advice at http://elinux.org/RPi_config.txt

Except in a fish pi.

It's unlike the fat one to ignore a thread with food references, no matter how vague.

I'll disagree with B, you should be able to login as a user then sudo su there is no need to sudo su once you are root.
sudo su will only ask for the password once.

I think I may have written B poorly

I think the advice means instead of logging in when the system boots as user "pi" log in with "sudo su" then do "startx"

Personally I just set a root password and have had no problems since

Hi, I have just got a Raspberry Pi and have encountered a problem. It is running squeezy and LXDE. When I try to look at the bottom of a Window I am unable to scroll to the bottom. I have tried making the window smaller and pushing it to the top of the screen but I still can't see the bottom of the Window. I have tried google for the solution. Any help would be appreciated. I am using composite cables not hdmi.

Try changing your TV resolution - maybe auto so the screen might resize.

You may have overscan enabled for a regular TV, try to disable it.
