It doesn’t occur under UnixWare 2. The user can force the panel timings to be recalculated from the modeline with 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. Which results in the x mode only expanded to x So for the various Chips and Technologies chips the maximum specifications are. The Xserver assumes that the framebuffer, if used, will be at the top of video ram. This may be related to a bug in one of the accelerated functions, or a problem with the BitBLT engine.

If it is a non-standard mode, maybe you need to tweak the timings a bit. This option forces the two display channels to be used, giving independent refresh rates. You have been warned!
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. We also thank the many people on the net who have contributed by reporting bugs and extensively testing this server.
The server will then allow the mode to occupy the whole x LCD. The amount of ram required for the framebuffer will vary depending on the size of the screen, and will reduce the amount of video ram available to the modes.
These option individually disable the features of the XAA acceleration code that the Chips and Technologies driver uses.
The server will limit the maximum dotclock to a value as specified by the manufacturer. This can be fixed by using the ” 18BitBus ” option. With the release of XFree86 version 4. Firstly, the memory requirements of both heads must fit in the available memory.
Chips and Technologies drivers – Chips and Technologies Video Drivers
It often uses external DAC’s and programmable clock chips to supply additional functionally. Hence the maximum dot-clock might need to be limited.
So using this option disables the XVideo extension. The memory bandwidth is determined by tecn.65550 clock used for the video memory. For 24bpp on TFT screens, the server assumes that a 24bit bus is being used.
This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card.
A ” letterbox ” effect with no stretching can be achieved using this option. Tceh.65550 Chips and Technologies chipsets supported by this driver have one of three basic architectures. Leaving too little memory available for the cache will only have a detrimental effect on the graphics performance.
By default it is assumed that there are 6 significant bits in the RGB representation of the colours in 4bpp and above. The driver is capable of driving both a CRT and a flat panel cnips.
Information for Chips and Technologies Users
An 8bpp one and a 16bpp one. There is the limit of the maximum dotclock the video processor can handle, and there is another limitation of the available memory bandwidth. Which results in the x mode only trch.65550 to x However some video ram, particularly EDO, might not be fast enough to handle this, resulting in drawing errors on the screen. This support can be used to give a single display image on two screen with different refresh rates, or entirely different images on the two displays.
The correct options to start the server with these modes are. This option allows the user to force the server the reprogram the flat panel clock independently of the modeline with HiQV chipset.
At this point no testing has been done and it is entirely possible that the ” MMIO option will lockup your machine. This option can be used in conjunction with the option “UseModeline” to program tech.655500 the panel timings using the modeline values.
Legal values are 2 to inclusive. This option, selects an 18 bit TFT bus. Additionally, the ” Screen ” option must appear in the device section.
