DAY 1
my OLD unit was Win XP SP2
i installed ubuntu 10.10 desktop, from cd, on it
(NOT DUAL BOOT)
==========
ECS P4M800-M
P4 - 1.8 GHZ
1x1GB + 1x512MB RAM
80 GB HDD
==========
i had no problems with the installation, no errors
now for the problem:
when i purposely login wrong user/pass, it says "Authentication Failure"
when i login my correct username & password
after i login my username & password, the screen turns black for a few seconds and returns to login screen
i tried the LiveCD and thats what also happens i input user & pass for LiveCD( user: ubuntu, pass: ), screen turns black and returns to login screen
also i cant access terminal when i press ctrl+alt+f1-fN
when i press it, the upper half it displays some random red vertical lines
in the bottom half it shows the desktop bg

Try booting up in recovery mode. Hold down shift during boot-up, when you see the grub menu, choose the recovery option with the most recent kernel (closest to the top, make sure it says "recovery")
When it asks you how you want to proceed, choose to enter a root console with networking.
From there you can try logging in or entering the command "startx" and see if that works.
I had this problem once because I uninstalled ubuntu-desktop
So try "sudo apt-get install ubuntu-desktop" If "startx" doesn't work.
---------------------------------------------
now, i get stuck in the boot menu, i cant move up, down or 'e' or 'c'
it seems to hang up when it show the boot menu
DAY 2
i installed 10.04, from cd, and the same thing still happens in login and boot menu
maybe my unit is incompatible?
after i installed 10.04, when the cd tray ejected on its own my whole screen was filled with an "i/o error" in sector
ill try to reinstall again and put the actual error here
>> [ 2504.698873 ] end_request: I/O error, dev sr0, sector 507136
thats one of 'em, the whole screen is filled with them.
DAY 3
i tried to install Win XP SP2 again
when i boot up it shows "Boot from CD: Press any key to boot from CD....", then i press enter
there a blinking underscore, in the upper left, in a black background for a few seconds and then boots up ubuntu
i tried to use KillDisk(Free) but it hangs up, just like the boot menu i cant move up, down and enter to choose an option
and then im thinking i can't use killdisk because it is for NTFS, am correct?
DAY 4
ANOTHER = another fresh installed 10.04, my same cd, in another cpu which boots up with no problem and doesnt ask for user/pass because i selected automatic login
MINE = my 'problematic' hdd which can't enter desktop in my cpu
now i inserted ANOTHER in my cpu and it gets the same problem. asks for user/pass and cant go to desktop
now i inserted MINE on ANOTHER's cpu and it boots up properly and doest ask for a user/pass
======================================
now i dont know what to do.
i can accept the fact that i can't use ubuntu, on my cpu, but i still want to know why.
