Ubuntu: Lubuntu 14.04 cannot try Lubuntu without installing-error messages


I have Lubuntu 13.10 installed. Works great. I downloaded Lubuntu 14.04 and burned to disc.

To test I tried the option to try Lubuntu without installing.

I got several error messages which I did not understand.

The first error message contained the following:

"Kernel Panic-not syncing"

There were other error messages that followed plus a lot of codes.

Then the last error message contained the following:

"drm_kms_helper: panic occurred switching back to text console"

I had to cold reboot. Nothing worked. Computer completely froze including t

he keyboard, mouse and I could not even eject the disc until the cold reboot.

This did not happen with 13.10 which installed smoothly with no problems 6 months ago.

Sounds to me like a kernel problem although I would think it would work just to try Lubuntu without installing. I remember trying a pre-release Kubuntu 14.04 and I was able to try it without installing just fine.

Is there a fix or should I attempt to download the image again and re-burn to disc.

Please advise if possible. I was very suprised it did not work considering Lubuntu 13.10 and a pre-release Kubuntu 14.04 worked.

Thank you in advance for any assistance.


After you downloaded Lubuntu 14.04 did you perform an MD5Sum? https://help.ubuntu.com/community/HowToMD5SUM The hashes have to match and perhaps yours don't. If they do not, download the ISO again.
