Gazelle laptop hobbled after Ubuntu reinstall

**grimnebulin** · April 18th, 2013

Hello--

A few months ago I purchased a Gazelle Professional laptop. I've been very happy with it.

Recently I executed an errant dpkg command that ran roughshod over my system, deleting numerous critical system files. I was left with no choice but to reinstall Ubuntu from DVD. The process was unexpectedly painless, even preserving my home directory, but I'm left with a system that's broken in some important ways:

1. The touchpad is nonresponsive, and remains so even after I press FN+F1.
2. There's no sound.
3. When I open the hibernating laptop, the screen flashes briefly, but then remains dark. I have to power-cycle it and log back in to get back to the desktop.
4. After a minute or so of use, a dialog appears, presenting an important-looking but vague warning: "System program problem detected / Do you want to report the problem now?"

Tips for how to remedy any or all of these issues would be greatly appreciated.

this may be of use
have you been into the sound settings and touchpad settings?

So I called the System76 support number and explained my issues. I was told that the most likely scenario was that my Ubuntu DVD had been corrupted as I downloaded and/or burned it, and that I should try again, using a slower burn speed. Also, clicking the "download third party software" checkbox before installing has been known to cause problems, apparently.

Since I had no more blank DVDs at hand, I tried installing again with my original DVD, and incredibly, it worked! That third-party software must be a killer.

The only lingering issue was that swiping the trackpad with two fingers didn't scroll windows as it normally did, but installing the System76 drivers and rebooting restored the usual functionality. I'm back in business!
