Comment 43 for bug 404421

So I made a little more progress.

In that syslinux folder, there is a file called text.cfg. I opened that file with notepad, and found some lines which looked similar to what you described. In the first 2 instances where I saw the "boot=casper", I highlighted the "casper" part and pasted "casper -- i915.modeset=0" and then saved the file. (Just to note, only the Fedora LiveUSB creator worked https://help.ubuntu.com/community/Installation/FromUSBStick . Other USB programs produced what seemed like an identical set of files on my USB, including the USB creator included in the .iso itself, but only the Fedora one makes this work for me.)

And this almost worked. I booted once again from the USB, chose the 2nd option, which was to install (first option was to just run the system off of the USB), and it progressed fully through the installation procedure, all the way through to the final reboot, upon which I was prompted to remove the USB. I did, and the system booted from what I had installed on the hard drive. But during the boot process, the same problem. The change was not maintained in the installation.

Now, I am running just the live USB, and will try the installation option from the Ubuntu desktop itself instead of the installation directly from the USB. I will post again if doing it this way will work.

But if that does not work, please tell me where I can find that text.cfg file on the fully installed system. This way, I could run from the USB, and then browse through the files on the hard drive and edit the file that way.
