Thread: nVidia Screen Shifting Problem

ok, so, here's interesting problem.

have 64-bit machine set nvidia graphics card, set dual-head secondary output tv multimedia.

now, correct resolution display 1680x1050. listed 1 of available resolutions in nvidia control panel. however, when set resolution display, whole display shifted 400px left.

means ubuntu menu out of sight on side of display, , there's wide black bar down right-hand side. handful of other resolutions well. 1680x1050 worked brief period of time, can't seem coerce behaving life of me!

i've tried manually setting modeline in xorg.conf file in order specify display properties, after disabling automatic resolution selection via edid, in case can 'unsupported output' monitor. i've tried both versions of driver listed in hardware manager, no avail.

have ideas?

here's info machine:

card id:
01:00.0 vga compatible controller: nvidia corporation g94 [geforce 9600 gt] (rev a1)

nvidia driver version: 173

xorg.conf:

lastly, though less importantly, xvideo extension broken machine. i've reset media players, it's not big deal. skype uses xv if available, , cannot configured not to. i've tried few of workarounds i've seen online none of them can make work properly. i've tried disabling xvideo in xorg.conf, gets loaded anyway. i'm assuming due module dependency, don't know how go fixing this. if has info on issue well, it'd helpful.
