Hello and thanks for checking out the post. I have some issues that I consider critical and would appreciate any help you can offer. Keep one more person away from the Microsoft Machine...

SYSTEM:
Samsung N120 netbook running Ubuntu Netbook Remix 9.10

First, I've posted this before but no solution was found so here I go again. I use my netbook with a 22" Acer display. If I want to sit and stare at the screens without running programs, it's fantastic. Anytime I run anything full screen, I either get the black or frozen screen. Depending on what it is, sometimes I get sound. Everything works perfectly when I use 800x600 reso.

Second, I was downloading something the other day and the file couldn't finish because I had run out of space. For whatever reason, there seems to be a 30- or 40-gig cap on my home drive so nothing else could go there. I was suggested to create a folder elsewhere and go from there. That works, but it's not what I want to do. I prefer to keep all of my system files separate from my useless crap.

Third, when I uninstall some programs, there's some stupid files that get left behind-- like application icons that stay on my desktop. I discovered the beauty of the Package Manager which helped a lot, but didn't get everything.


Okay-- that's it for now... but I must warn you. I'm a complete Linux beginner but I'm computer savvy. You'll probably have to explain a lot but I'm a quick study. Thanks in advance... I really don't want to go back to Windows.

To remove totally remove a package, in theory you should be to do:

sudo dpkg --purge <package name>

I appreciate the quick response... here's what I got:

dpkg: warning: ignoring request to remove onboard which isn't installed.

Is this something I might have to just search through the package manager to find?

Run df in a terminal to see the space left on your partitions and file systems.

It's pretty easy using synaptic to remove the left-over configuration files from programs you've removed.

In the system menu, there is a "hardware drivers" menu entry: maybe there is a non-free driver for your acer monitor or graphics card. You may try running without "visual effects" (see the appearance preferences in the system menu).

It's usually more than just config files... Data files, icon images... just random, dumb crap. I've been using Synaptic to get rid of what I can find but some of it is elusive. Is there any sort of global preference that includes these things in the uninstall? I always look for the relevant checkboxes during individual installs.

Thanks for the tips about the graphics card-- I'll frig around with that when I'm back at my apartment.
