When constructing a modeline for use with the Chips and Technologies driver you’ll needed to considered several points. This has been reported on some configurations. A sample of an incomplete ” xorg. Leaving too little memory available for the cache will only have a detrimental effect on the graphics performance. The xx MMIO mode has been implemented entirely from the manual as I don’t have the hardware to test it on. Powered by Create your own unique website with customizable templates. The xx chipsets can use MMIO for all communications with the video processor.

The chipset has independent display channels, that can be configured to support independent refresh rates on the flat panel and on the CRT. Legal values are 2 to inclusive. The server itself can correctly detect the chip in the same technolkgies.

This might further reduce the available memory. Using this option the user can override the maximum dot-clock and specify any value they prefer.

The ct chipset introduced a new dual channel architecture. So using this option disables the XVideo extension.

Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets. This effectively means that there are two limits on the dotclock.


Except for the HiQV chipsets, it is impossible for the server to read the value of the currently used frequency for the text console when using programmable clocks. A basic architecture, the WinGine architecture which is a modification on this basic architecture and a completely new HiQV architecture. For this reason the default behaviour of the server is to use the panel timings already installed in the chip.

The problem here is that the flat panel needs timings that are related to the panel technologes, and not the mode size. The Xserver assumes that the framebuffer, if used, will be at the top of video ram.

If you use the ” overlay ” option, then there are actually two framebuffers in the video memory. You can avoid this by either using the ” NoStretch ” option or removing the HWcursor ” option. Many laptops use the programmable clock of the x chips at the console. Firstly, the ct tecnhologies must be installed on a PCI bus. By default the two display share equally the available memory.

Try this if the cursor seems to have problems. For other depths this option has no effect. Note that linear addressing at 1 and 4bpp is not guaranteed to work correctly. Chips and Technologies specify that the memory clock used with the multimedia engine running should be lower than that used without.

Note that increasing the memory clock also has its own problems as described above. 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.

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.

This can result in a reddish tint to 24bpp mode. This chip is specially manufactured for Toshiba, and so documentation is not widely available. In general the LCD panel clock should be set independently of the modelines supplied.

Information for Chips and Technologies Users

Many LCD displays are incapable of using a 24bpp mode. However the panel size will still be probed. A ” letterbox ” effect 685544 no stretching can be achieved using this option.

You are logged in as. This option sets the centering and stretching to the BIOS default values. As mentioned before, try disabling this option.
