It is believed that this is really just a with a higher maximum dot-clock of 80MHz. So if you have a virtual screen size set to x using a x at 8bpp, you use kB for the mode. This driver uses this capability to include a 16bpp framebuffer on top of an 8bpp framebuffer. The flat panel timings are related to the panel size and not the size of the mode specified in xorg. For LCD modes, it is possible that your LCD panel requires different panel timings at the text console than with a graphics mode. For this reason it is recommended to use one of the programs that automatically generate xorg. 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.

Using this option the mode can be centered in the screen.

The reason is that first the installer setup file is downloaded, and then the installer software does the work of fetching your driver from our fastest download server. By default the two display share equally the available memory.

This might make certain modes impossible to obtain with a reasonable refresh rate. At this point no testing has been done and it is entirely possible that the ” MMIO option vhips lockup your machine.

You can avoid this by either using the ” NoStretch ” option or removing the HWcursor ” option. This also gives more memory bandwidth for use in the drawing operations.


For other depths this option has no effect. This disables use of the hardware technoligies provided by the chip. If you use the ” overlay ” option, then there are actually two framebuffers in the video memory. Hence I hope that this section will clear up the misunderstandings.

However it additionally has the ability for mixed 5V and 3. The user can force the panel timings to be recalculated from the modeline with this option. The ct supports dual-head display. However there is no reliable way of probing the memory clock used in these chipsets, and so a conservative limit must be taken for the dotclock limit. The forms given below are the preferred forms. This is a more advanced version of the WinGine chip, with specification very similar to the x anr of chips.

None of these are currently supported within the driver itself, so many cards will only have limited support. If you see such display corruption, and you have this warning, your choices are to reduce the refresh rate, colour depth or resolution, or increase the speed of the memory clock with the the ” SetMClk ” option described above. If technolgoies is a non-standard mode, maybe you need to tweak the timings a bit. Note that this option only has an effect on TFT screens.


So if you have a virtual screen size set to x using a x at 8bpp, you use kB for the mode. This option might be used if the default video overlay key causes problems. Note that linear addressing at 1 and 4bpp is not guaranteed to work correctly.

This has been reported on some configurations. A ” letterbox ” effect with no stretching can be achieved using this option.

Therefore the server uses a default value of 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. One the overall maximum, and another chiips to the available memory bandwidth of the chip.

The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel clocks, where the options above set the clocks to 65MHz. If you have a problem with the acceleration and these options will allow you to isolation the problem. Hence the maximum dot-clock might need to be limited. 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.

This is a debugging option and general users have tehcnologies need of it. It has the same ID and is identified as a when probed. Mobile, Mac OS and Linux users can choose other download options by deselecting the installer checkbox below the download button. It also includes a fully programmable dot clock and supports all types of flat panels.
