Ubuntu 12.04 can't boot after hardware support update

[gold_finger]

I'm afraid someone else is going to have to try answering this for you.  I'm too confused by the whole thing.  Really don't understand what the deal is.  Ubuntu 12.04 is good until April 2017 -- so I have no idea why some kind of upgrade is necessary.  Maybe it's fine if you leave it with its original kernel; but you need to upgrade if you use the HWE stuff you talked about?  I don't know.

In the meantime, I suppose you're stuck not being able to boot into it properly.  I'd just boot with live DVD/USB, copy off what you want saved and start over again.  Either re-install 12.04 or test out and install 14.04.  Then just copy back your saved data.  If you do that, direct the bootloader installation to Ubuntu's root partition (sda5) to keep LL in charge of booting (After U install, boot LL and sudo update-grub to have it listed on grub menu.).  If you want Ubuntu to take control, then install it to the MBR (sda).  (If you've upgraded LL to 2.0, then don't let Ubuntu take control of booting.  LL 2.0 has customized grub in a way that won't easily be booted by other OS without manual modifications.  Best to just let LL 2.0 stay in control.)

Hey,

So I tried the command you suggested and the system came back to me saying that HWE start is supported until April 2017, which would suggest that it's definitely installed.

But something about read/write cache failed which I reckon is what the problem is.

Also, I've had a little look around the forums and Scott(0) and Valtam have suggested that it's an upgrade that has to be done as the current LL is out of support on the 8/8/14.  So one way of another I think I have to upgrade but I don't want to end up like by Ubuntu.

So I don't know whether this is counted as hardware fault - in not supporting the graphics? - or an error has occurred whilst trying to install.

Ok, keep in mind this is all foreign to me -- never even heard of the HWE before your post.

Re-read that HWE link and think I have slightly better understanding of it.

My guess is that you upgraded the kernel, but the graphics stack to go with it did not get upgraded yet which is now the reason you can't start the GUI interface.  (I could be way off base on this guess.)

Boot up into Ubuntu tty and try running the command for the HWE status.  Don't know if you need to run with sudo or not, try w/o sudo -- if doesn't work use sudo.

Code: [Select]

hwe-support-status --verbose
Or

Code: [Select]

sudo hwe-support-status --verbose

I have no idea what you will see running that, but the HWE link said that if you didn't have the graphics stack installed it would inform you how to proceed with that.  Go ahead and see if that helps.  If confused by instructions shown after running command, try to write down what is shown and post back here with that.

Good luck!

P.s. Since you tried deleting the new kernel, running above command may try to reinstall it.  Go ahead and let it do that if you don't see an option to fix graphics by itself.  Maybe it will fix graphics at same time.  If after reinstalling new kernel, still won't boot in GUI -- run command again to see if it now offers graphics fix.

Thanks for the reply guys.

gold_finger you definitely seemed to have grasped the scope of my problem and the set up of my computer.

I'm not sure what my HWE environment is, however, I did install the hardware support update to Ubuntu 12.04 and haven't do so to my Linux 1.0.8.

I go into the recovery menu to boot into Ubuntu ttyl but am unable to startx from when I've prior tried.  I could try sudo updating the grub (as I thought boot repair would do this automatically), but I guess it's worth trying again just to make sense of the situation.

Ok, so upon my last response I updated the grub it responds saying that I have LL 1.0.8, Ubuntu 12.04 and WinXP and a couple extra updates I do believe, as expected.

I went into the non-GUI interface and was unable to run startx but discovered there is a cache file read/write error of such and that HWE stack is valid until April 2017.

Crunch182,

I'm not familiar with the HWE packages.  Read the link you provided, but I'm still not really clear on what it is for.

From what I understand:
* You have LL 1.0.8 installed and in control of booting (it's root is sda7)
* You have Ubuntu 12.04 installed and that's what you tried installing the HWE package on (root=sda5)
* You have Windows XP installed to sda1

* You can boot into both LL and Win XP normally.
* Can not boot graphically into Ubuntu anymore

I could boot into the non-GUI ttyl version of Ubuntu but am unable to figure how to get into the lovely GUI version I like.

Are you saying that if you pick the Ubuntu choice from the grub menu it boots in non-graphic mode?  Or are you getting to that in some other way?

Can you log in and run commands?  If "yes", log in and run

Code: [Select]

startx
or, it might be

Code: [Select]

sudo startx
Did that start GUI?



To eliminate the easiest possibility first:  did you run an update to grub after you had installed the HWE in Ubuntu.

*  From within LL 1.0.8 (not Ubuntu), run this:

Code: [Select]

sudo update-grub
*  Reboot and pick Ubuntu to see if it made any difference.

Hi Crunch182,
Thanks for this information. Help me understand what your final result is: What version of Linux Lite and HWE are you now running?  Thanks.

Re from previous post:  https://www.linuxliteos.com/forums/index.php?topic=306.0;topicseen

As prior mentioned in the link above I relatively installed a hardware support update through the update manager in Ubuntu 12.04 and since then have been unable to access the OS, at all but continually use LL and WinXP.

I pointed out that I could boot into the non-GUI ttyl version of Ubuntu but am unable to figure how to get into the lovely GUI version I like.

I have tried using the Boot Repair utility (as suggested on the official Ubuntu forums) and have had no luck, I also tried deleting the new kernel but that didn't work either.

This was the output I received from Boot Repair:
http://paste.ubuntu.com/7837640/

FYI, this supposed hardware output was released for the following reason, if you care to read the Ubuntu webpage - I can kind of being careless and lazy didn't really follow to reading it as understanding that it was hardware support I made the conclusion it had to be good.
https://wiki.ubuntu.com/1204_HWE_EOL

When I deleted the newest Ubuntu kernel I used the synaptic package manager and looked under kernels and went to the most recent of these.  I should state that upon using the Boot Repair utility that LL controls the grub whereas it was Ubuntu previously.

If you have any questions or need more info just tell me, I'll try get back to you as soon as I can.

Finally, I do appreciate all comments, suggestions and solutions guys so thanks.
