Dell Inspiron 1525 Auto Reboots

[gold_finger]

I deleted the post you made immediately before the above one with green box around it because it looks like you mistakenly posted a duplicate.

Also, not sure if you meant to use the green check arrow on that post marking as "best answer" or not because this post is not solved by that answer.  Couldn't figure out how to remove the green check to unmark it as best answer.  Maybe only you can do that?  Or maybe it can't be removed once checked?  I don't know, but am going to ignore that and continue trying to solve the problem.

I only have linux operating system on this computer, there is a partition with the original Dell/Windows operating info on it

That original Dell/Windows partition is no longer on the drive.  As shown in your parted -l output, only Linux partitions are currently there.  If Dell partition were on the drive, parted would show it (even if it were a "hidden" partition).



The output from cat /etc/X11/xorg.conf command shows that the file never got created from my prior instructions to force recognition of the Intel video driver.  (You may have forgotten to save the file when you followed those instructions last time.)

Let's try creating that file again.  Boot into LL and open a terminal.  Then enter this command:

Code:

gksu leafpad /etc/X11/xorg.conf

Enter your password when asked for it, then your text editor (leafpad) will open up with a blank file called /etc/X11/xorg.conf.

Copy/Paste the following lines (including the indented formatting) as shown into the leafpad editor that opened up.

Code:

Section "Device"
        Identifier "My device"
        Driver "intel"
EndSection

In the text editor, go to File -> Save to save the file.  (The Leafpad command above already named the file "/etc/X11/xorg.conf", so just pick File -> Save, not File -> Save As.)

Close the text editor.

Close the terminal window.

Reboot computer and see what happens.
