I always thought resizing or doing any partition editing carried some risk of losing data (ie no guarantees), but perhaps ext3 is different. Anyways, I think I have ruled out the low swap explanation: On Fri, Feb 22, 2008 at 2:19 AM, Selim T.

Right after boot, I logged in to tty1 and did a sudo pm-hibernate While staring at the screen for messages, I noticed that the snapshot image was less than 400 MB, and it correctly determined free swap as just short of 1.4 GB - so swap is more than enough. On resume, I got a lot of beeps, but after waiting for like 2-3 minutes or so, I was back at my console prompt. However, when I tried to switch over to gdm on tty7, the screen is black, system goes unresponsive, and I can't get back to my tty1 anymore. Just as an experiment, I did a sudo hibernate -v3 > hibernate.out, and it says that it was unable to unload nvidia and aborts hibernation (see attached file). So I guess pm-hibernate kind of went ahead and shut down without properly taking care of nvidia, so that is why I had an unresponsive X server on resume, right? If that's what's happening, is there any way to get nvidia properly unloaded? I am running a stock kernel, and have nvidia installed from the Debian repositories. Also, there's a script in this article I found: http://www.linux.com/feature/114220. I never like running scripts that I don't understand, and I was wondering if whatever it's doing with the video card solve my problem?
