This is a debugging option and general users have no need of it. Normally the colour transparency key for the overlay is the 8bpp lookup table entry Try this if the cursor seems to have problems. This option is only useful when acceleration can’t be used and linear addressing can be used. This disables use of the hardware cursor provided by the chip. This can be done by using an external frame buffer, or incorporating the framebuffer at the top of video ram depending on the particular implementation.

Please read the section below about dual-head display. There is the limit of the maximum dotclock the video processor can handle, and there is another limitation of the available memory bandwidth. This option, selects an 18 bit TFT bus. Also the maximum size of the desktop with this option is x, as this is the largest window that the HiQV multimedia engine can display.

Which is the reason for the drop in the dot clock. With this option all of the graphics are rendered into a copy of the framebuffer that is keep in the main memory of the computer, and the screen is updated from this copy. When the size of the mode used is less than the panel size, the default behaviour of the server is to align the left hand edge of the display with the left hand edge of the screen. Note that the ” -bpp ” option has been removed and replaced with a ” -depth ” and ” -fbbpp ” option because of the confusion between the depth and number of bits per pixel used to represent to framebuffer and the pixmaps in the screens memory.

The default behaviour is to have both the flat panel and the CRT use the same display channel and thus the same refresh rate. This information will be invaluable in debugging any problems. This is a techmologies advanced version of the WinGine chip, with specification very similar to the x series of chips.

If technologes have a problem with the acceleration and these options will allow you to isolation the problem. However, some machines appear to have this feature incorrectly setup.

Hence you will see a line like. This option forces the server to assume that there are 8 significant bits.

Information for Chips and Technologies Users

XFree86 believes that the 8bpp framebuffer is overlayed on the 16bpp framebuffer. It is enabled by default for machines since the blitter can not be used otherwise. In addition to this many graphics operations are speeded up using a ” pixmap cache “. The exception is for depths of 1 or 4bpp where linear addressing is turned off by default. Additionally, the ” Screen ” option must appear in the device section. The correct options to start the server with these modes are. This has been reported on some configurations.

In this way PseudoColor and TrueColor visuals can be used on the same screen. Work is underway to fix this.

It might affect some other SVR4 operating systems as well. Alternatively the user can use the ” TextClockFreq ” option described above to select a different clock for the text console. Use caution as excess heat generated by the video processor if its specifications are exceeded might cause damage. For some machines the LCD panel size is incorrectly probed from the registers. It is possible to force the server to identify a particular chip with this option. In this case the driver divides the video processors dotclock limitation by the number of bytes per pixel, so that the limitations for the various colour depths are.

In fact if the video BIOS on the machine sets the ct to a dual channel mode by default, X will lockup hard at this point.

So the driver will attempt to round-up the virtual X dimension to a multiple of 64, but leave the virtual resolution untouched. Firstly, the ct chipset must be installed on a PCI bus.

However the panel size will still be probed. This serial link allows an LCD screens technoogies be located up to m from the video processor. If it is a standard mode and frequency that your screen should be able to handle, try to find different timings for a similar mode and frequency combination. Many LCD displays are incapable of using a 24bpp mode.
