    nVidia update disabled desired resolution

    Today there was a security update to 'nvidia-current' in Precise:

    nvidia-graphics-drivers-updates (304.88-0ubuntu0.0.1) precise-security; urgency=low

    * SECURITY UPDATE: ARGB Cursor Buffer Overflow in "NoScanout" Mode
    - CVE-2013-0131

    * New upstream release
    - Fixed CVE-2013-0131:
    NVIDIA UNIX GPU Driver ARGB Cursor Buffer Overflow in
    "NoScanout" Mode. This buffer overflow, which occurred
    when an X client installed a large ARGB cursor on an
    X server running in NoScanout mode, could cause a denial
    of service (e.g., an X server segmentation fault), or
    could be exploited to achieve arbitrary code execution.

    [ Alberto Milone ]
    * debian/dkms.conf{.in}:
    - Drop all the patches.
    * debian/substvars:
    - Add support for xorg-video-abi-14.

    But along with that they dropped other patches and in my case it removed my desired resolution of 1440x900. This is the xrandr with the old driver:

    Code:
    lance@lance-AMD-desktop:~$ xrandr
    xrandr: Failed to get size of gamma for output default

    And here's the xrandr with the new driver:

    Code:
    lance@lance-AMD-desktop:~$ xrandr

       800x600        75.0     72.2     60.3     56.2  
       640x480        75.0     72.8     59.9
    Any thoughts on how I can get the desired mode back in the updated driver?

    The xorg.conf has very little in it:

    Code:
    Section "Device"
    	Identifier	"Default Device"
    	Option	"NoLogo"	"True"
    EndSection
    A long time ago I used this same monitor with Intel graphics and I'd have to use this xorg.conf:

    Code:
    Section "ServerLayout"
    	Identifier     "X.org Configured"
    	Screen      0  "Screen0" 0 0

    So I sort of think I could just add the "Monitor" and "Screen" sections of that to my xorg.conf like this but I'm not sure:

    Code:
    Section "Device"
    	Identifier	"Default Device"
    	Option	"NoLogo"	"True"
    EndSection
    
    Section "Monitor"
    	Identifier   "Monitor0"
    	VendorName   "Monitor Vendor"
    	ModelName    "Monitor Model"
            Modeline     "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync
            Option       "PreferredMode" "1440x900_60.00"
    EndSection
    
    Section "Screen"
    	Identifier "Screen0"
    	Device     "Card0"
    	Monitor    "Monitor0"
    	SubSection "Display"
    		Viewport   0 0
    		Depth     1
                    Modes    "1440x900@60"
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     4
                    Modes    "1440x900@60"
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     8
                    Modes    "1440x900@60"
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     15
                    Modes    "1440x900@60"
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     16
                    Modes    "1440x900@60"
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     24
                    Modes    "1440x900@60"
    	EndSubSection
    EndSection
    I've been lucky enough that I haven't had to mess with an xorg.conf in a very, very long time
