This option, selects an 18 bit TFT bus. This allows the user to select a different clock for the server to use when returning to the text console. Further to this some of the XAA acceleration requires that the display pitch is a multiple of 64 pixels. A basic architecture, the WinGine architecture which is a modification on this basic architecture and a completely new HiQV architecture. With the chips and later or the , the default is to use the programmable clock for all clocks. Modeline “x 8bpp” So for unexplained problems not addressed above, please try to alter the clock you are using slightly, say in steps of 0.

Also for non PCI machines specifying this force the linear base address to be this value, reprogramming the video processor to suit.

For a complete discussion on the dot clock limitations, see the next section. It is possible to use the fixed clocks supported by the chip instead by using this option. There is no facility in the current Xservers to specify these values, and so the server attempts to read the panel size from the chip. The memory bandwidth is determined by the clock used for the video memory. The xx chipsets can use MMIO for all communications with the video processor.

This is a problem with the video BIOS not knowing about all the funny modes that might be selected. Note that it is overridden by the ” SWcursor ” option. This might cause troubles with some applications, and so this option allows the colour transparency key to be set to some other value. It checks everything such as sound card, graphic card, monitor, mouse, printer, etc.


Note that this option only has an effect on TFT screens. Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets. If the user has used the ” UseModeline ” or ” FixPanelSize ” options the panel timings are derived from the mode, which can be different than the panel size.

For LCD screens, the lowest clock that gives acceptable contrast and flicker is usually the best one. The following options are of particular interest to the Chips and Technologies driver.

The exception is for depths of 1 or 4bpp where linear addressing is turned off by default. Although the authors of this chipx have tried to prevent this, they disclaim all responsibility for any damage caused by the software. Hence I hope that this section will clear up the misunderstandings. The server will limit the maximum dotclock to a value as specified by the manufacturer.

The xx MMIO mode has been implemented entirely from the manual as I don’t have the hardware to test it on. The formula to determine the maximum usable dotclock on the HiQV series of chips is. Many DSTN screens use frame acceleration to improve the performance of the screen.

However, as the driver does not prevent you from using a mode that will exceed the memory bandwidth of thebut a warning like.

Firstly, the memory requirements of both heads must fit in the available memory. The ct chipset introduced a new dual channel architecture. However some video ram, particularly EDO, might not be fast enough to handle this, resulting in drawing errors on the screen.

This driver must be considered work in progress, and those users wanting stability are encouraged to use the older XFree86 3. Now the maximum memory clock is just the maximum supported by the video processor, not the maximum supported by the video memory. For other screen drawing related problems, try the ” NoAccel ” or one of the XAA acceleration options discussed above.

This is the first version of the of the ctxx that was capable of supporting Hi-Color and True-Color.

For this reason, the maximum colour depth and resolution that can be supported in a dual channel mode will be reduced compared to a single display channel mode. This is a small and long-standing bug in the current server. This chip is basically identical to the This is a very similar chip to the It has the same ID and is identified as a when probed.
