crunch182,

Yours is a separate issue from that of original post on this thread.  Please start a new post of your own under "Start up and Shutdown" section.  It's best to keep separate problems on their own thread and also your new thread is more likely to get attention than posting to end of an old one.

When you make new post, can you go into more detail on what you meant by this:

... I installed the hardware support on Ubuntu ...
What "hardware support" are you talking about and how exactly did you install it?

Also, explain process you used for this (and I assume you're talking about Ubuntu, not LL):
Quote
I tried the deleting newest kernel

I looked at your Boot-Repair output.  Seems that Ubuntu is in charge of booting the computer and you have several kernels for both Ubuntu and LL.  It sounds like you can still boot to LL and Windows without any problems and only having problems booting into Ubuntu.  Confirm on new post if that is correct.  Also, have you tried booting into Ubuntu using one of the older kernels listed on grub menu?

Hi guys,

That is useful information, I was wondering if you have a solution or just a word of wisdom to my little problem.  I am/was running Ubuntu 12.04, LL (of course) and WinXP.

But I guess carelessly I installed the hardware support on Ubuntu and now I'm unable to access the OS unless through the non-GUI ttyl, which of course I personally don't want.

I tried the deleting newest kernel after reading it's kind of an upgrade to Ubuntu 12.10, however, no luck!  I posted on the Launchpad forums as well but no idea really.

By the way, this is output from Boot repair:

http://paste.ubuntu.com/7837640/
I have tried the boot repair utility but no luck, would this mean I would have to reinstall Ubuntu?  Plus, how would I be able to clean up the kernels if that's the case as the most recent - which I tried to uninstall/delete - is still present on the boot menu.

Thanks for any help/suggestions.

Hello!

Yes, it would definitely appear that Linus Torvalds prefers non-journaling file systems such as ext2. As for reiserfs, I've never tried it myself. As long as you have a desktop with a UPS or a laptop/netbook with a good battery, ext4 - which is what I use nowadays - is fine.

Now when I first got my netbook, it had no battery, so I used ext2 with Lubuntu, but the kernel got to a point a couple of releases ago where it wouldn't shut an ext2 file system down properly anymore. Since I had bought a good battery for the netbook by then, I went exclusively to ext4 at that point.

I have an ancient laptop with a totally dead battery, so on THAT one, I use ext2. So far, no problems, knock wood...

@N4RPS,

Thanks for the links.  Very interesting.  Don't know if it's still a hotly debated issue these days, but seems that it was when ext4 was brand new.  Apparently Linus didn't like ext3 either.  My knowledge of the inner workings of different file systems is basically zero, so I'll leave that to the experts I suppose.  Will probably just continue using ext4 myself just because it seems to be the standard and I don't have any issues (that I know of) with it.

Just out of curiosity, have you ever experimented with or used BTRFS or Reiser?  I seem to remember reading some good things about them and have thought of trying one or both on a test machine at some point in the future.

I'd also be interested in reading any links you may have where Linus explains this position.

http://www.linux-magazine.com/Online/News/Linus-Torvalds-Upset-over-Ext3-and-Ext4

Here's one from https://lkml.org/lkml/2006/6/9/183:

"Just as an example: ext3 _sucks_ in many ways. It has huge inodes that take up way too much space in memory. It has absolutely disgusting code to handle directory reading and writing (buffer heads! In 2006!). It's conditional indexing code is horrible. Its performance absolutely sucks when the journal is being drained or something.

Are you going to improve on any of those _fundamental_ problems? Or are you going to make them worse?

Hint: I'm betting you're not going to improve them by adding more features."

At the end of the day, if you lose power before the journaling FS has the chance to writes the data to disk, You WILL lose it. Period. How much damage it does depends on how much data accumulates to be written before power is lost.

BSD/FreeBSD is one of the few OSs that can survive a power hit, but who writes very much non-mission-critical stuff for BSD?

These aren't EXACTLY what I read somewhere 'back in the day', but it relates, in a way, to what I'm saying. To me, it's not that much of a stretch, but I'm stretching this too far for comfort, I'm willing to 'take a hit' on it.

It's sort of like remembering that Sarah Palin made the claim on national television that 'abstinence is unrealistic', but you can't find anything online to support that statement. However, one CAN find proof online that both Bristol Palin AND Levi Johnston, her 'baby daddy, DID say that. They both got it from SOMEWHERE...

Most Linux installs these days use the ext4 format, a journaling file system. Journaling file systems are VERY unforgiving when it comes to sudden power outages.

If you lose power without notice frequently, you may want to use ext2 to install Linux Lite.

I'm not trying to start a debate here, but everything I have read indicates the exact opposite of this -- that ext4 file systems are more robust and are less likely to suffer data loss and corruption from sudden crashes than ext2.  Perhaps I'm missing something.  Do you have any links that explain what you stated?  I'd be interested in reading them.

Linus Torvalds, the creator of Linux, avoids journaling file systems like the plague, He uses ext2 to format EVERYTHING...

I'd also be interested in reading any links you may have where Linus explains this position.


@ochilds,

Go ahead and try using Boot-Repair as suggested by N4RPS.  If it doesn't work, hopefully you can use the live DVD to copy off your important data before reinstalling the system.

Hello!

There is a utility that can be ran from a LiveCD called Boot-Repair that I have used to repair Ubuntu boot-related issues in the past, but never with Linux Lite. More info here:

https://help.ubuntu.com/community/Boot-Repair

If this does not work for you, you may not have any other choice than reinstalling Linux Lite.

My computer shut down abruptly due to a power outage and I cannot get it to re- boot . The screen comes up in terminal mode and displays the following message: Linux Lite 1.0.8 LTS ochilds-Dimension-4300 tty1 and then ask for login. When I put in the proper login info, it displays the message login incorrect. Can anyone help?
