Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I've seen similar topics posted numerous times, and I'm sorry for another, but I can't seem to find an answer that works for/pertains to my problem.
I'm running Kubuntu Edgy on a Dell Inspiron 9300 Laptop and an ATI Mobility Radeon X300 using fglrx. When I go to shut down, the screen does a few vid card flickers, but I don't get the shut down splash- everything just goes blank. Not even a blinking cursor. If I wait a few moments, my fans kick on.. a sure sign that my CPU is going full tilt.
I'm unable to Ctrl+F2 to get to a login prompt and end up having to manually power off the machine (I believe that the LCD is turning off before it should, so while I probably could use Ctrl+F2 to get back in, I simply can't see it 'cause the display is off).
This is my second installation of Kubuntu (did a freshy last week) and when I first had it installed, shut own worked fine, but I couldn't suspend. Now, I'm able to suspend and resume when I open the lid (though sometimes it works, sometimes it doesn't) but not shut down. Rebooting gave me a blinking cursor ever so often, but that seems to be working fine, now.
I don't think I've installed or did anything all that differently from my previous installation, so I dunno what might have changed. I've been going through my system with a fine tooth comb, fixing/tweaking issues that arise, and all has been going rather well 'n smooth.. but this is one annoyance I can't seem to troubleshoot on my own.
Is there something I need to add to my xorg.conf? Maybe something to do with ACPI?
Thanks in advance.
EDIT: I thought I'd add a few configuration files to this post so mebbe people can point out some flaws. For the most part, they haven't been tweaked very much.

Well, yes and no. I actually ended up doing another fresh install (because I'm that anal retentive), and I don't seem to be having the problem anymore... but that's how it was last time. All was well, then I probably futzed with something (probably my ATI card, been playing with that often to see just what can and cannot be done with various drivers), and it broke my shut down. I haven't thoroughly tested standby/hibernation yet, though.
Should I still add your suggestions to /etc/modules?
As for being contagious... *bats lashes innocently* I'll try to cover mah mouth when I cough out a forum post, next time.
Im having the (seemingly) same problem. Running Kubuntu 6.10. When I am in a session and I log out, options for "restart" and "shutdown" lead to a blank screen (monitor switches off) and system just hangs.
This is about my 8th install of Kubuntu (Im a noob so I opt for the format when I mess something up, which is rather frequent since I like pushing buttons). But this problem happens by default on EVERY install Ive done so far. It works fine on my laptop, its obviously something specific to this setup. Im thinking hardware, maybe video card (Radeon 9600) but I just dont know what Im doing enough to figure out the problem.
I can "sudo reboot" or "sudo shutdown" from the konsole and that works fine but I cant get it from the buttons.
I did change ACPI settings somewhere (I dont remember the file name) but I told it to stop switching off the monitor when I reboot, and when I did that, shutting down/restarting led to the kubuntu status screen with blue bar and it just sat there for a few seconds, switched to a blank screen with flashing cursor and i could type whatever I liked, then after 3 seconds or so would switch back and hence be stuck in a loop.
If anybody has the solution please let me know!!! THANKYOU!!!
Please do not send private e-mails to LQ members (like you have done with me) as this is against LQ rules. If you have problems post it in the forum.
I didn't fix the problem: sometimes kubuntu shuts down properly and sometimes it does not. I suspect this is caused by some sort of conflict with wireless device, as when it is off I can shutdown from kde.
For the time being I'm shutting down typing "sudo poweroff -h now" from terminal, I will try to fix the problem in the next future.
Hm, upgrading to 7.04 is precisely what caused this problem to appear on my laptop (w/ ATI Radeon™ Xpress 200M), and only when fglrx is used. I'm going to try some of the suggestions and see what happens... This is actually the first description I've come across that exactly mirrors what I'm experiencing.
did you ever fix this problem with the logout on your laptop? i think i have the same problem - log out gives me a black screen instead of the GDM login screen, nothing can be done except hard reboot. also an ATI 200M card, with fglrx drivers; the problem also started for me after uprading from edgy to feisty. it's a single-user laptop so i rarely log out, but it's still vexing.
Hm. Actually, I had fixed this problem on my laptop a while ago; my apologies for not posting the solution here. I agree that it's a very annoying situation, and I had resorted to either using the commandline to reboot/shutdown or killing X the ctrl+alt+bksp way to just logout... then I realized that killing X held the key to the solution --
