LinuxQuestions.org - Toshiba Satellite A70 running Debian Sound, Mouse, Video Problems

Hi,

I know I posted elsewhere, but I wasn't getting any answers there...
I recently purchase a Toshiba Satellite A70 laptop, and am trying to run Debian Linux on it. However, I ran into a number of problems, I tried google but to no avail. Specifiically, I have:
no sound
my touchpad mouse does not work (I have a wireless mouse for now that works
perfectly, but I would enjoy being able to use the touchpad)
my resolution is only 1024x768. Since I have a widescreen capable of running
1280x800, I would like to be able to run at that resolution.

The only error I get is for my sound, when I startx I get an error saying /dev/dsp no such file or directory sound will be outputted to dev/null I believe. I have no idea what files I should include to help you guys solve my problem, much less who makes my soundcard, as Toshiba is less than helpful. --EDIT-- I got this from CNET, but it appears that Toshiba no longer carries my laptop anymore, even though I bought it from them about 2 months ago :( CNET says this about my sound card: Audio codec - Realtek ALC250

The mouse and resolution problems aren't quite as severe, as I know I just need to edit my xf86 file correctly to get them to work, but I would appreciate it if anyone has a copy of theirs that I could look off of. Here is a short copy of mine:
--EDIT-- WOW... I'm such a n00b... On a hunch, to change my resolution all I did was manually edit the file so that in my Display section, instead of 1280x1024 I put 1280x800... I thought It would take more work than that. Amazing how simple that was!
