Setting up Multiboot from ISOs

Hello all,

I am trying to set up a desktop kiosk-style computer at my local Library, based on Ubuntu.

My idea is to have a regular desktop mainly  for browsing the Web, but I would also like it to be able to reboot into an ISO by clicking an icon on the Launcher.

I specifically would like to use the Linux Gamers.net [1] and another ISO compressed as squashfs and using syslinux to boot.

I am having trouble configuring the GRUB2 menuentries to boot these as ISOs and I have no idea how to create a launcher to boot the computer to the ISOs.

The computer isn't strong enough for a VM...

Thank you,

Amichai.

USB stick error

I set up a USB stick, 32 gigs, to boot Ubuntu on the wife's laptop. Got
it booted up and updated it. Got it all set up, then I rebooted it. It
came back with a black screen with the following on it:

Busybox v1.22.1 (Ubuntu 1:1.22.0-8ubuntu1) built-in shell (ash)
Enter 'help' for a list of commands.
(initramfs) unable to find a medium containing a live file system.

I have no idea where to start.

I go into System Settings and then printer and the Add button is greyed

Any ideas?

Firefox problems

Hi,

I have, in the past week only, been having problems accessing two very 
popular websites.  These are bbc.com and weather.gov.  It fails to 
display when I visit bbc.com and control is transferred to 
static.bbci.co.uk.  Firefox displays other sites OK.

I am using Mint Linux (Mate desktop) and the Firefox browser is 30 (for 
Mint 1.0).  I was using the adblock, noscript, flash block and ghostery 
add ons and thinking that one of them was misbehaving, I disabled all of 
the add ons.  It did not change anything.

At first, I thought it was specific to these two websites thinking that 
they were experiencing a denial of service attack or some other internet 
related problem.  Other websites were unaffected such as google, you 
tube and many other websites.  These websites work just fine when I dual 
boot to Windows and use the Windows version of Firefox.  Has anybody 
experienced the same thing?

Yes, gparted has very bad habits. You tell it ti change something and it changes other things without telling you. You save the changes and later find out that you have problems that need to be corrected. gparted is crap, it would be much better if it only changed what it was told to change.

Only once has Gparted.iso let me down but it turns out the drive jumper was bad and the boot sector on the drive was unfixable but for storage its OK and that took a bit of time to work out.

2 TB external HD does not mount any more. How to save it's data?

Hello Everybody.

 

A few years ago, I formatted a 2 TB Western Digital external hard disk formatted into ext4. Ever since then, I have been using it to backup my data. However, ever since a few months, the device is becoming less functional. Now, I do not any more manage to mount it. On the other hand, the device still does show up via lsusb and GParted. The latter packages mentions 'input-output errors' and only sees an 'unallocated' space.

 

It is crystal clear to me that the device needs to be reformatted in order to get it functional again. However, I first need to recover the data. How best to do so?

 

Thanks, respectfully yours,

Bas G. Roufs.

Network Drawing tools

Are there any Linux network drawing tools?

I don't really want a full-blown Network Management solution like
OpenNMS or Nagios, I just want an easy way to map my home network that
doesn't require me to do it all manually.

Keyboard won't accept input

I'm running Ubuntu Gnome 14.04 using a Logitech wireless keyboard through a KVM switch.

I was working last night when the keyboard suddenly stopped working.
The hardware seems fine as it works when I switch to the Windows machine.
 I haven't got a clue where to start troubleshooting - or how for that matter.
I can cut and paste but cannot type, in a terminal or any application.

Where/how do I begin sorting this out?

reporting kernel bugs

How do I report kernel bugs to Launchpad via the command line? I've been
noticing my system locking up and today decided to go through my syslog
snippets thoroughly and noticed this each time there was a lockup:

Dec 13 14:40:57 localhost kernel: [154858.820009]
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render
ring idle

Doing some Googling I see that this goes back as far as 12.04 that I can
see. 

Thanks for any assistance.

Chris

unable to open x config file for writing

Hi all

using 12.04.05, 2 nvidia cards, 3 monitors.  last week an update borked the one card, now only 2 monitors work.  nvidia settings didnt show the second card, updated from 304 to 331 thinking that would help.  no dice.  went back to 304, and using edgers ppa via some forum post i read, and now the 2nd nvidia card shows up in nvidia-settings.

trying to activate the 2nd card, im given a "new x screen required", no big deal, its always done that. then click save to x config file, as always, and receive the error "unable to open x config file for writing" .  tried nvidia settings as root as well, same error message.

Creating USB Stick with Ubuntu

Although I have recently begun using Centos I now want to create a Ubuntu USB stick to use when traveling, doing so I have run into problems.
 
The stick is a 64 Gb stick to allow for lots of persistent data on it, I created a couple of partitions but cannot get grub to work (I intentionally choose to use grub, not grub2, to gain familiarity with the older version).
 
I followed the instructions at https://rudd-o.com/linux-and-free-software/a-better-way-to-create-a-customized-ubuntu-live-usb-drive since it seemed to be low-level for me to learn the basics. I made a couple of changes: (1) I changed the disk format from FAT32 to ext2 for the boot partition to allow for a larger boot partition: (2) the initrd.gz file now seems to be called initrd.lz and I made that change.
 
At the end, however, I cannot get the USB stick to boot from the two computers I tried it on, none of which I believe uses UEFI booting. I believe I need to use grub2, not grub, if I want the stick to boot on a computer using UEFI?
 
Is it possible for someone knowledgeable to suggest what might be wrong? My basic assumption is that grub can be used to boot Ubuntu 14.04.1. I also want to do this at the low level, not use a tool to create the USB stick.
 
Second, if there is a low-level description how to create such a stick this using grub2 for UEFI booting, please point me to it since I may eventually have to do this to allow the stick to be truly usable.
 
Thank you.
