VirtualBox -- Create VM for Booting Live ISOs/CDs/DVDs
N4RPS:
Hello!
1. Try using canned air to blow out the heat sink and fan(s). You'd be surprised how dirty they can get.
2. Memory issues can also cause freezes. Try popping out the RAM stick(s) and GENTLY cleaning the contacts on both sides of it/them with a pencil eraser, rub off any residue with an alcohol-wetted cloth or cotton swab, and reinserting them. Gold DOES tarnish, and sometimes, that tarnish is invisible on the contacts.
3. Lastly, I'd try repasting the CPU heat sink. CPUs usually plug into zero-insertion-force (ZIF) sockets. GPUs are most likely fastened to the mobo using little solder balls (ball grid array, or BGA), and usually don't cause issues that aren't caught on the assembly line first. Your GPU might even have a heat sink that can be repasted.
None of these suggestion can hurt at this point...

Wirezfree,
Just an update to let you know I haven't forgotten this.
Tried a fresh install of LL on spare laptop, then tried running old remastersys from deb files downloaded from here: http://sourceforge.net/projects/os4systemimage/files/Remastersys%203.0.4-2/. It would not run properly and gave me an error message stating that lightdm was not setup properly, or something to that effect.
However, that laptop has had many problems and seems to be on its last legs. I kept running into problems with it freezing up completely after it was running for a while, with no option other than hard shutdown. (Even "REISUB" shutdown method didn't work.) I also tried another LL installation followed by installing Valtam's test kernel to see if that would help. It didn't -- had same freezing problem.
Basically what I'm saying is I can't be sure that the remastersys failure was due to incompatibility of the program or due to physical component problems that computer has and are getting worse. Here are things I know/suspect are wrong with it:
* A physical solder point on either the CPU or GPU is bad -- causing inconsistent boot behavior.
* There is a problem with power management as it seems to drain battery quickly. Even when powered off after fully charging battery (a new one), the battery will be dead after few days to a week when go to turn laptop back on.
* Stongly suspect that the GPU is on the verge of failure because laptop heats up quickly and the failing GPU most likely is what causes the freeze-ups. (Could also be that CPU needs re-seating with new thermal paste, but pretty sure it's the GPU.)
Anyway, I may get time within next week or so to test remastersys on a different computer. Will post back when/if I do.

Hi gold_finger,
Yes, I could just do an install of LL2 into VBox.
I just liked the idea of having an exact mirror of what I have now.
Thanks... Dave

So have a VM of that, rather than clean OOB and start again.

That's what I figured you wanted.

After a few Google's it appears remastersys is now being developed by a new team
Here is an update 1st March 2014, But no GUI yet

Thanks for update link -- knew they took over project but wasn't aware they came out with any new code.
I'll try experimenting a bit either today or tomorrow on spare computer. Will try out old version of remastersys first to see if it works on 14.04 (LL 2.0) because it has a GUI interface, making things easier. If doesn't work, I'll try out new code from above link and see what happens. Will report back when done.
P.s.
Worst case scenario if remastersys doesn't work -- just install to VM, manually make same changes to system, then take a "Snapshot" (in VBox) of it to save its original state. Revert VM to snapshot anytime you need to backtrack to original state.

Hi gold_finger,
Many thanks...

I will checkout "remastersys" first and see if that fits the bill.
