We recommend that you try and pick a mode that is similar to a standard VESA mode. If this is a problem, a work around is to remove the ” HWcursor ” option. 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. See ct for details. Note that many chips are capable of higher memory clocks than actually set by BIOS.

This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card. The user can force the panel timings to be recalculated from the modeline with this option.

It doesn’t occur under UnixWare 2. For this reason it is recommended to use one of the programs that automatically generate xorg. So using this option on a xx chipset forces them to use MMIO for all communications.

If the user has used the ” UseModeline ” or ” FixPanelSize ” options the panel timings are derived from the mode, which can be different than the panel size. Note that it is overridden by the ” SWcursor ” option.

An 8bpp one and a 16bpp one. Note that this option using the multimedia engine to its limit, and some manufacturers have set a default memory clock that will cause pixel errors with this option. The programmable clock makes this option obsolete and so it’s use isn’t recommended. This is a more advanced version of the WinGine chip, with specification very similar to the x series of chips.


For other screen drawing related problems, try the ” NoAccel ” or one of the XAA acceleration options discussed above.

Try reducing the clock. One the overall maximum, and another due to the available memory bandwidth of the chip. However it additionally has the ability for mixed 5V and 3. This can be done by using an external frame buffer, or incorporating rech.65550 framebuffer at the top of video ram depending on the particular implementation.

So the value actually used for the memory clock might be significantly less than this maximum value. Options related to drivers can be present in the Screen, Device and Monitor sections and the Display subsections. For a complete discussion on the dot clock limitations, see the next section. This is correct for most modes, but can cause some problems. A general problem with the server that can manifested in many way such as drawing errors, wavy screens, etc is related to the programmable clock.

That is from 0 to for 8bit depth, 0 to 32, for 15bit depth, etc. However, some machines appear to have this feature incorrectly setup. This might make certain modes impossible to obtain with a reasonable refresh rate.

This shouldn’t affect higher depths, and is fixable with a switch to the virtual console and back.

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. However, 8 and 24 bit colour depths seem to work fine. 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.

This option forces the LCD panel size to be overridden by the modeline display sizes. The memory bandwidth is determined by the clock used for the video memory. The driver is capable of driving both a CRT and a flat panel display. The flat panel timings are related to the panel size and not the size of the mode specified in xorg.

This may be related to a bug in one of the accelerated functions, or a problem with the BitBLT engine.

The Xserver assumes that the framebuffer, if used, will be at the top of video ram. Like the overlays, the Xvideo extension uses a part of the twch.65550 memory for a second framebuffer. A basic architecture, the WinGine architecture which is a modification on this basic architecture and a completely new HiQV architecture.
