Video card drivers?

[gabe2]

I'm still having no luck whatsoever trying to change the resolution. I've been looking at all kinds of different fixes and none of them appear to work (or maybe I'm not doing it right, I don't know). Also, I can't seem to adjust the brightness of the screen because my slider is gone for some reason. Is there a fix for that as well?

Please help, I'm quite eager to learn about this OS and the potential troubleshooting I gotta do. This is sort of research for building my grandmother a simple and user-friendly computer that isn't tempermental. The resolution and slider are really the two big remaining items that I need to fix here, I'm so CLOSE!

For the record, here's what xrandr says:
Screen 0: minimum 8 x 8, current 1024 x 768, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DVI-I-2 connected 1024x768+0+0 (normal left inverted right x axis y axis) 520mm x 330mm
1024x768 75.0*+ 70.1 60.0
800x600 75.0 72.2 60.3
640x480 75.0 72.8 59.9
640x350 70.1
HDMI-0 connected (normal left inverted right x axis y axis)
1024x768 75.0 + 70.1 60.0
800x600 75.0 72.2 60.3

What kind of cable are you using to connect the monitor? Is a VGA, DVI or HDMI?

Also, could you paste the content of this file:

/var/log/Xorg.0.log

Please paste it here: paste.ubuntu.com, and then post back the link to it.

Regards.

DVI

I tried entering that line code in the terminal, it told me that permission is denied?

Whoa! I just noticed something interesting. On a lark, I switched over to the Guest Session and the resolution there is CORRECT!

*EDIT* I copied & pasted the contents of the xorg.conf file from the Guest Session (after saving using NVIDIA X Server) to my account, that appears to have fixed the problem, now I have the correct resolution.
