Why are you trying to overwrite this file at all? MichaelHampton by default there's no file, which works fine with one monitor setups. But once you have multiple monitors, you need to write the config into the xorg. Users can't write into that file if it doesn't exist. Add a comment. Active Oldest Votes. Improve this answer.

I'm aware of that option, but the average users configures the computer with the nvidia-settings program. The nvidia-xconfig program just provides a skeleton, but once the user wants to configure multiple screens, you use nvidia-settings. Would not that be sufficient for option? Click here for more info.

I don't recall ever being offered a I looked at the release notes and don't recall seeing any issues that I had to be concerned with before the upgrade. The actual upgrade went flawlessly with this one exception.
What's the best way to go about working through the broken package or messed over config file? Would it be good to apt-get purge all relevant items and reload? If so what items do I dump? Or is there a better answer. I have a Does any of this help? I seem to recall it moved at some point. And some poking around shows that D3 BIOS reference refers to the Ethernet card which is working just fine despite the message.

Your screen may flicker for a second and you should then see a drastic improvement. Test out Firefox and moving windows. Did the fix work for you? Once you've determined that this does indeed fix your issue, we'll need to make sure it's permanent. If it didn't work or caused an issue, simply reboot and you'll be back to your normal desktop.
Now that we've determined that our fix works, to resolve screen tearing once and for all, it's time to make the changes stick. First we need to make sure you have an xorg. To find out, type the following command into a terminal and press Enter :. For those with an xorg. Now open the file with your favorite text editor I'm a fan of nano text editor myself as root and enter the following command:.
Screen number This option is mandatory for cards where a single PCI entity can drive more than one display i.
One Device section is required for each head, and this parameter determines which head each of the Device sections applies to. The legal values of number range from 0 to one less than the total number of heads per entity.
Most drivers require that the primary screen 0 be present. Chipset " chipset " This usually optional entry specifies the chipset used on the graphics board. In most cases this entry is not required because the drivers will probe the hardware to determine the chipset type. Don't specify it unless the driver-specific documentation recommends that you do. This is only used by a few of the drivers, and in most cases it is not required because the drivers will probe the hardware to determine the RAMDAC type where possible.
The speed is in MHz. When one value is given, it applies to all framebuffer pixel sizes. When multiple values are given, they apply to the framebuffer pixel sizes 8, 16, 24 and 32 respectively. This is not used by many drivers, and only needs to be specified when the speed rating of the RAMDAC is different from the defaults built in to driver, or when the driver can't auto- detect the correct defaults.
Clocks clock The clocks are in MHz, and may be specified as a floating point number. The value is stored internally to the nearest kHz. The ordering of the clocks is important. It must match the order in which they are selected on the graphics board. Multiple Clocks lines may be specified, and each is concatenated to form the list.
Most drivers do not use this entry, and it is only required for some older boards with non-programmable clocks. Don't specify this entry unless the driver-specific documentation explicitly recommends that you do. ClockChip " clockchip-type " This optional entry is used to specify the clock chip type on graphics boards which have a programmable clock generator. Only a few Xorg drivers support programmable clock chips. For details, see the appropriate driver manual page. VideoRam mem This optional entry specifies the amount of video ram that is installed on the graphics board.
This is measured in kBytes. In most cases this is not required because the Xorg server probes the graphics board to determine this quantity. The driver-specific documentation should indicate when it might be needed. MemBase baseaddress This optional entry specifies the memory base address of a graphics board's linear frame buffer. This entry is not used by many drivers, and it should only be specified if the driver-specific documentation recommends it. This can be used to override the auto- detection, but that should only be done when the driver-specific documentation recommends it.
ChipRev rev This optional entry specifies the chip revision number. This can be used to override the auto-detection, but that should only be done when the driver-specific documentation recommends it.
MatchSeat seat-id Only apply this Device section if X server was started with -seat seat-id option. Option "ModeDebug" " boolean " Enable printing of additional debugging information about modesetting to the server log. Option "PreferCloneMode" " boolean " If enabled, bring up monitors of a screen in clone mode instead of horizontal extended layout by default. Defaults to off; the video driver can change the default value, but this option can always override it Options Option flags may be specified in the Device sections.
These include driver-specific options and driver-independent options. The former are described in the driver-specific documentation. Some of the latter are described below in the section about the Screen section, and they may also be included here. Maybe nobody knows There should normally be at least one, for the monitor being used, but a default configuration will be created when one isn't specified.
Monitor sections have the following format: Section "Monitor" Identifier " name " entries EndSection The only mandatory entry in a Monitor section is the Identifier entry. The Identifier entry specifies the unique name for this monitor. The Monitor section may be used to provide information about the specifications of the monitor, monitor-specific Options , and information about the video modes to use with the monitor.
With RandR 1. Using the name of the output defined by the video driver plus the identifier of a monitor section, one associates a monitor section with an output by adding an option to the Device section in the following format: Option "Monitor- outputname " " monitorsection " for example, Option "Monitor-VGA" "VGA monitor" for a VGA output In the absence of specific association of monitor sections to outputs, if a monitor section is present the server will associate it with an output to preserve compatibility for previous single-head configurations.
Specifying video modes is optional because the server will use the DDC or other information provided by the monitor to automatically configure the list of modes available. When modes are specified explicitly in the Monitor section with the Mode , ModeLine , or UseModes keywords , built-in modes with the same names are not included. Built-in modes with different names are, however, still implicitly included, when they meet the requirements of the monitor.
The entries that may be used in Monitor sections are described below. VendorName " vendor " This optional entry specifies the monitor's manufacturer. ModelName " model " This optional entry specifies the monitor's model. HorizSync horizsync-range gives the range s of horizontal sync frequencies supported by the monitor. A range of values is two values separated by a dash. By default the values are in units of kHz.
The data given here is used by the Xorg server to determine if video modes are within the specifications of the monitor. This information should be available in the monitor's handbook. If this entry is omitted, a default range of kHz is used. VertRefresh vertrefresh-range gives the range s of vertical refresh frequencies supported by the monitor. By default the values are in units of Hz. If this entry is omitted, a default range of Hz is used.
DisplaySize width height This optional entry gives the width and height, in millimetres, of the picture area of the monitor. If given this is used to calculate the horizontal and vertical pitch DPI of the screen.
Gamma gamma-value Gamma red-gamma green-gamma blue-gamma This is an optional entry that can be used to specify the gamma correction for the monitor. It may be specified as either a single value or as three separate RGB values. The values should be in the range 0. Not all drivers are capable of using this information. UseModes " modesection-id " Include the set of modes listed in the Modes section called modesection-id.
This makes all of the modes defined in that section available for use by this monitor. Mode " name " This is an optional multi-line entry that can be used to provide definitions for video modes for the monitor.
In most cases this isn't necessary because the built- in set of VESA standard modes will be sufficient. The Mode keyword indicates the start of a multi-line video mode description. The mode description is terminated with the EndMode keyword. The mode description consists of the following entries: DotClock clock is the dot pixel clock rate to be used for the mode. HTimings hdisp hsyncstart hsyncend htotal specifies the horizontal timings for the mode. VTimings vdisp vsyncstart vsyncend vtotal specifies the vertical timings for the mode.
Flags " flag " HSkew hskew specifies the number of pixels towards the right edge of the screen by which the display enable signal is to be skewed. Not all drivers use this information. This option might become necessary to override the default value supplied by the server if any. If the last few pixels on a scan line appear on the left of the screen, this value should be decreased. VScan vscan specifies the number of times each scanline is painted on the screen.
Values less than 1 are treated as 1, which is the default. Generally, the "DoubleScan" Flag mentioned above doubles this value. ModeLine " name " mode-description This entry is a more compact version of the Mode entry, and it also can be used to specify video modes for the monitor.
This is a single line format for specifying video modes. In most cases this isn't necessary because the built-in set of VESA standard modes will be sufficient. The mode-description is in four sections, the first three of which are mandatory.
The first is the dot pixel clock. This is a single number specifying the pixel clock rate for the mode in MHz. The second section is a list of four numbers specifying the horizontal timings.
These numbers are the hdisp , hsyncstart , hsyncend , and htotal values. The third section is a list of four numbers specifying the vertical timings.
These numbers are the vdisp , vsyncstart , vsyncend , and vtotal values. The final section is a list of flags specifying other characteristics of the mode. Interlace indicates that the mode is interlaced.
DoubleScan indicates a mode where each scanline is doubled. Composite can be used to specify composite sync on hardware where this is supported.
The default is to enable the extension. Option "SyncOnGreen" " bool " This option controls whether the video card should drive the sync signal on the green color pin. Not all cards support this option, and most monitors do not require it. The default is off. Option "Primary" " bool " This optional entry specifies that the monitor should be treated as the primary monitor. RandR 1. All these keypad available modes are selected from the screen mode list.
This list is a copy of the compatibility output monitor mode list. Since this output is the output connected to the lowest dot-area monitor, as determined from its largest size mode, that monitor defines the available zoom modes. By default, the server will attempt to enable all connected monitors.
By default, the server will add default modes; you should only disable this if you can guarantee that EDID will be available at all times, or if you have added custom modelines which the server can use. Option "MaxClock" " frequency " This optional entry specifies the maximum dot clock, in kHz, that is supported by the monitor.
