This shouldn’t affect higher depths, and is fixable with a switch to the virtual console and back. XFree86 believes that the 8bpp framebuffer is overlayed on the 16bpp framebuffer. It often uses external DAC’s and programmable clock chips to supply additional functionally. This might cause troubles with some applications, and so this option allows the colour transparency key to be set to some other value. In general there are two factors determining the maximum dotclock. 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.

If you are driving the video memory too fast too high a MemClk you’ll get pixel corruption as the data actually written to the video memory is corrupted by driving the memory too fast. It has the same ID and is identified as a when probed.

It also includes a fully programmable dot clock and supports all types of flat panels. This is the first chip of the ctxx series to support fully programmable clocks. For a complete discussion on the dot clock limitations, see the next section.

Note that for the this is required teechnologies the base address can’t be correctly probed.

Using this option the user can override the maximum dot-clock and specify any value they prefer. For other screen drawing tdchnologies problems, try the ” NoAccel ” or one of the XAA acceleration options discussed above.

This driver uses this capability to include a 16bpp framebuffer on top of an 8bpp framebuffer.

So this limit will be either 56MHz or 68MHz for the xx chipsets, depending on what voltage they are driven with, or 80MHz for the WinGine machines. There has been much confusion about exactly what the clock limitations of the Chips and Technologies chipsets are.

However use caution with these options, because there is no guarantee that driving the video processor beyond it capabilities won’t cause damage.

This option might also be needed to reduce the speed of the memory clock with the ” Overlay ” option. Therefore to use this option the server must be started in either 15 or 16bpp depth. Dual-head display has two effects on the modelines.

This is usually due to a problem with the ” LcdCenter ” option. Similar to the but also incorporates “PanelLink” drivers. If the screen is using a mode that BIOS doesn’t know about, then there is no guarantee that it will be resumed correctly.

You have been warned! By default the two display share equally the available memory. However, as the driver does not prevent you from using a mode that will exceed the memory bandwidth of thebut a warning like.

Technologiee, 8 and 24 bit colour depths seem to work fine. However if you do try this option and are willing to debug it, I’d like to hear from you. Hardware ;ci effectively speeds all graphics operations as the job of ensuring that the cursor remains on top is now given to the hardware.

Like the overlays, the Xvideo extension uses a part of the video memory for a second framebuffer. At this point no testing has been done and it is entirely possible that the ” MMIO option will lockup your machine. Most of the Chips and Technologies chipsets are supported by this driver to some degree.


This option allows the user to force the server the reprogram the flat panel clock independently of the modeline with HiQV chipset. The servers solution to this problem is not to do doubling vertically. For this reason it is recommended to use one of the programs that automatically generate xorg.

By default linear addressing is used on all chips where it can be set up automatically.

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. So using this option disables the XVideo extension. The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel clocks, where the options above set the clocks to 65MHz. Option “NoAccel” This option will disable the use of any accelerated functions.

The server doesn’t prevent the user from specifying a mode that will use this memory, it prints a warning on the console.
