The logmask option is very handy to track down trouble in the driver. You should only enable this if you are doing so, otherwise keep it turned off because it slows down your system. (All lines have a '#' preceding 'logmask' by default.) Logging creates a logfile called <strong>nv.accelerant.0.log</strong> in your <strong>~ (home)</strong> folder. A second logfile may get created depending on how the driver is used (on cloning; for BWindowScreen for example). The second file is called <strong>nv.accelerant.1.log</strong>, and it will also be in your home folder.<br>

|
||||
If you select <strong>vga_on_tv false</strong> the driver will automatically shut-off your VGA (or DVI) monitor (by means of special internal DPMS settings) when a TVout mode is enabled on the head the monitor is connected to. This means that on singlehead cards and on dualhead cards using singlehead TV modes your only output will be on TV. This is the standard way of doing things.
|
||||
<li><strong>true:</strong> With this setting VGA (or DVI) output on a head is enabled concurrent with TV output on that head: that is if you select a TVout mode. This setting is a 'tweak' because the modeline used to drive your monitor is the same modeline that is used for the TV output. This means that the monitor picture positioning is probably a bit odd, in some modes it might distort somewhat, and the refreshrate will be 50Hz for PAL modes, and 60Hz for NTSC modes. Make sure you only enable this tweak if you know your monitor supports down to 50Hz refreshrate, and preferably has a failsafe built in that blocks output when out-of-range signals are sent to it (almost every newer monitor has this feature).<br>

|

<li><strong>primary:</strong> (set to disabled by default)<br>
|
||||
Primary lets you force a certain card to be used as primary card in your system if you have multiple graphics cards installed: so it will display your desktop. To enable this (hack) feature uncomment this item and fill in the exact name of the card that is to be primary (as exported by the kerneldriver in /dev/graphics/). If you are going to select a card other than the one displaying your system's POST messages at bootup, make sure you also set 'usebios false' as otherwise the card(s) aren't coldstarted by the driver.<br>

<strong>Note please:</strong>
|
||||
<ul>
|
||||
<li>DVI and laptop panels don't work yet with the 'usebios false' setting. Analog connected screens should work though.
|
||||
<li>Coldstarting doesn't work on TNT1 and GeForce 6xxx/7xxx cards yet.
|
||||
<li>Primary forces the primary card by preceding the exported name by a minus-sign (-) for the selected device. This ensures that this device will be listed at the top in the /dev/graphics/ folder, which is alphabetically ordered. Please make sure you enable the 'primary' feature on just one graphics driver, otherwise it's effect isn't 'guaranteed'.
