This serial link allows an LCD screens to be located up to m from the video processor. The xx chipsets can use MMIO for all communications with the video processor. In this case enough memory needs to be left for the largest unscaled video window that will be displayed. 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. This is useful for the chipset where the base address of the linear framebuffer must be supplied by the user, or at depths 1 and 4bpp. This is usually due to a problem with the ” LcdCenter ” option. This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card.

For some machines the LCD panel size is incorrectly probed from the registers. Dual refresh rate display can be selected with the ” DualRefresh ” option described above.

The overlay consumes memory bandwidth, so that the maximum dotclock technologiies be similar to a 24bpp mode. This is a driver limitation that might be relaxed in the future. This option is only useful when acceleration can’t be used and linear addressing can be used. With the release of XFree86 version 4.

It is possible to turn the linear cpi off with this option. By default linear addressing is used on all chips where it can be set up automatically. However use caution with these options, because there is no guarantee that driving the video processor beyond it capabilities won’t cause damage.


This chip is similar to the but has a 64bit memory bus as opposed 6550 a 32bit bus. The HiQV series of chips doesn’t need to use additional clock cycles to display higher depths, and so the same modeline can be used at all depths, without needing to divide the clocks.

If you use the ” overlay ” option, then there are actually two framebuffers in the video memory. In this case enough memory needs to be left for the largest unscaled video window that technllogies be displayed. This driver must be considered work in progress, and those users wanting stability are encouraged to use the older XFree86 3.

There is the limit of the maximum dotclock the video processor can handle, and there is another limitation of the available memory bandwidth.

The ct supports dual-head display. However there are many older machines, particularly those with x screen or larger, that need to reprogram the panel timings. This might further reduce the available memory. The memory bandwidth is determined by the technologoes used for the video memory. It overrides the options “LcdCenter” and “NoStretch”. The programmable clock makes this option obsolete and so it’s use isn’t recommended. Hi-Color and True-Color modes are implemented in the server.

That is from 0 to technolobies 8bit depth, 0 to 32, for 15bit depth, etc.

The effect of this is that the maximum dot clock visible to the user is a half or a third of the value at 8bpp. So with the ” Overlay ” option, using the ” SetMClk ” option to reduce the speed of the memory clock is recommended.


However some video ram, particularly EDO, might not be fast enough to handle this, resulting in drawing errors on the screen. This option forces the LCD panel size to be overridden by the modeline techjologies sizes.

This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card. The order of precedence is Display, Screen, Monitor, Device.

The reason for this is that the manufacturer has used the panel timings to get a standard EGA mode to work on flat panel, and these same timings don’t work for an SVGA mode. Which is the reason for the drop in the dot clock. This is useful to see that pixmaps, tiles, etc have been properly cached. Many laptops use the programmable clock of the x chips at the console.

This option sets the centering and stretching to the BIOS default values. It is believed that this is really just a with a higher maximum dot-clock of 80MHz.
