Bootup Problem. Alert! /dev/disk/byuuid... does not exist
location: ubuntuforums.com - date: March 4, 2012
I just tried to install Ubuntu 11.10 after verifying that everything works properly by testing with a LiveUSB setup. The LiveUSB boot works properly and I then successfully installed the NVidia driver 290.10 for my GeForce 520 graphics card.
The full install, onto an external USB HDD, however won't successfully boot. I put Grub2 onto the USB drive and select it from the BIOS boot options. The normal boot stalls with a blank screen. A bootup with the recovery option provides more feedback, the last message is:
[2.276032] usb 2-1: config 1 interface 0 altsetting 0 endpoint 0x81 has an invalid bInterval 0, changing to 32.

Then I get a message that BusyBox v1.18.4 (Ubuntu 1:1.1..4-2ubuntu2) has loaded.
At this point I don't think the kernal has loaded, I'm not sure what BusyBox is.

After compiling my new kernel (i tried both 2.4.4 and 3.5-rc) and I try to boot my kernel I got the error in the subject:
ALERT! /dev/disk/by-uuid/5a86a3b5-3bb8-461c-b60f-0b89753d3b78 does not exist. Dropping to shell
This happens only to my new kernel (the old 3.2 boots ). I tried recompiling with more scsi and ata options but no luck. I guess there is some module i need that i missed to check, but i am not sure what.
This is the output of:

debian shell prompt does not reflect changed hostname
location:
linuxquestions.com - date:
October 27, 2012
When I change the hostname in /etc/hostname and reeboot the machine, the shell prompt still shows the old hostname.
Command hostname shows the correct, newly set name.
Shell prompt is defined as:
PS1 = ${debian_chroot:+($debian_chroot)}\
[email protected]\h:\w\$
I have already checked /etc/init.d/hostname.sh, tried it manually with start parameter, and it correctly echoed the new name.
So, the value of \h in PS1 seems to be resolved from somewhere else - any ideas?
Thanks!

How to change color depth when xorg.conf does not exist?
location: ubuntuforums.com - date: November 21, 2009
Hi there,
Just installed Xubuntu 9.10 on my old laptop. Everything works fine but I want to change color depth to 16 bit. IIRC, that is done on /etc/xorg.conf but this file does not exist on my hard drive. I did:
sudo find / -name xorg.conf
but file was not found.
Any ideas on how to change the color depth when this file does not exist?
Thanks,

RH9 NIS login error: "home directory does not exist"
location: linuxquestions.com - date: August 5, 2003
Hi-
I finally got NIS authentication going, but every time I try to log in, I get a popup that says "Your home directory is listed as /home/myusername but it does not appear to exist. Do you want to log in with the root dir as your home dir? It is unlikely anything will work unless you use a failsafe option"
You have the choice of "yes" or "no" but either choice just dumps you back to the login prompt.
My goal is to get it to automatically mount the home folder off the server for any user that logs in on any machine. I do NOT want to have to create a folder for each user on each machine! Any ideas?
Thanks!
[SOLVED] ALERT! /dev/disk/byuuid/xxxxxxxxxxxxxxxxxx$ does not exist
location: ubuntuforums.com - date: May 30, 2008
I'll have to start by explaining some things. I updated yesterday and installed a new kernel. Later on, I tried to install something in the terminal when it informed me to execute 'dpkg --configure -a'(I think), which I did and it informed me a new version of Grub was available. It gave a me a list of options to install it, so being unsure I chose 'package maintainers version' or something along those lines.
When I booted up today I was greeted by a messy, disorganized boot screen that had my old kernel options, then in the other operating systems section was Windows, the new kernel, and the old kernel. So I booted into the new kernel and then edited grub. I commented out the old kernel version, then copy pasted the new kernel lines at the top and deleted the additional old kernel lines. Basically I cleaned up menu.lst to look like my old one before the update to grub, except with the new kernel listed instead. I must have done something wrong because I now boot into Busybox

Ubuntu 9.10
2.6.31-16-generic
Acer Extensa 5620Z Laptop
I have been running Karmic Koala from a fresh install for the last several weeks with NO problems.
Tonight, I ran the update. While it was running, I locked my screen. I came back later and unlocked the screen and the update had completed and was waiting to reboot. I answered the prompt indicating that I would reboot later, closed all open screens, and then selected the Ubuntu menu reboot option.
The boot-up got as far as displaying the Ubuntu circle, but no progress line. Eventually the screen went black.
I power off and when I turn the machine back on, I get the grub menu. If I select recovery mode, I see:
Gave up waiting for the root device. Common problems:
-Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
-Missing modules (cat /proc/modules: ls /dev)
