Gateway nv7915u: Screen Res & Audio problems

[whiskey.will]

So I have just acquired a new laptop the Gateway nv7915u (or "desktop replacement" according to gateway, see:http://ubuntuforums.org/showthread.p...hlight=nv7915u) and wiped Windows 7 to begin tweeking my Ubuntu to match my previous machine, but there are a few issues I wasn't experiencing before:

[1.] there's no sound (http://ubuntuforums.org/showthread.p...hlight=nv7915u) and I haven't even figured out where to begin with this. If you have any ideas they would definitely help as the main reasons I own a computer are for Music & Banking...

[2.] the native screen resolution is 1600x900 and I am unable to achieve this. The highest I can get through the system>preferences>display menu is 1024x768. I have been trying the Xrandr command in terminal but I can't exactly figure it out (a step-by-step would be extremely helpful here), here are the current settings and I would like to achieve 1600x900...

will@Wills-GateWay:~$ xrandr
Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 61.0*
800x600 61.0
will@Wills-GateWay:~$

I hope someone has already figured this out, I'm sure the Ubuntu Folk we'll know of something to do...

Thanks to MCWHO, my [2.] problem has been resolved with much ease. For future user's that encounter this same issue follow these simple directions, I would say read over them once just for your benefit before proceeding and you'll be as good as gold...

so is upgrading the kernel working well for you?

I have the same machine as you but am having display issues, as in no display on the Ubuntu partitions of a dual boot with Win7 setup.

Everything worked fine after the initial install, but then I started monkeying around with the mode/modeline settings in my xorg.conf file to get the 1600x900 display.

Now, I get a blank screen after selecting either of the Ubuntu options from the Grub boot menu.

I can't even get to a terminal/command prompt anywhere except for the Grub shell, which doesn't offer enough capability to over write the modified (and apparently now faulty) xorg.conf file with the backup I made before starting...

The new kernel is working perfectly with the RESOLUTION not the AUDIO though, if you have any updates on that please post them... All I did was follow the directions I posted and it worked fine, I didn't do any tweeking though...
