Using an 8bpp, the colour will then be displayed incorrectly. Try a lower dot clock. It also reduces the effect of cursor flashing during graphics operations. There has been much confusion about exactly what the clock limitations of the Chips and Technologies chipsets are. This disables use of the hardware cursor provided by the chip. XFree86 believes that the 8bpp framebuffer is overlayed on the 16bpp framebuffer. This reduces the amount of video ram available to the modes.

It is also possible that with a high dot clock and depth on a large screen there is very little bandwidth left for using the BitBLT engine. It is possible to use the tecy clocks supported by the chip instead by using this option. The Chips and Technologies chipsets supported by this driver have one of three basic architectures.

Because the rendering is all done into a virtual framebuffer acceleration can not be used. This option forces the second display to take a particular amount of chipss. Chips And Technologies, Accelerator new. Micon Graphics Card Drivers 10 models.

A ” letterbox ” effect with no stretching can be achieved using this option. Otherwise it has the the same properties as the However careful use of this option might boost performance. In the first instance, the model positions itself as a solution for engineers, graphics professionals, animators as well as other people, searching for a large working area.


So the driver will attempt to round-up the virtual X dimension to a multiple of 64, but leave the virtual resolution untouched.

You can avoid this by either using the ” NoStretch ” tevh or removing the HWcursor ” option. However, 8 and 24 bit colour depths seem to work fine. The problem here is that the flat panel needs timings that are related to the panel size, and not the mode size. The server will limit the maximum dotclock to a value as specified by the manufacturer. This can be found from the log file of a working cips installation. In its current form, X can not take advantage of this second display channel.

Hercules Graphics Card Drivers 2 models. Maintaining updated Hitachi Graphics Card software prevents crashes and maximizes hardware and system performance. The chipset has cuips display channels, that can be configured to support independent refresh rates on the flat panel and on the CRT. If you find you truly can’t achieve the mode you are after with the default clock limitations, look at the options ” DacSpeed ” and ” SetMClk “.

For LCD screens, the lowest clock that gives acceptable contrast and flicker is usually the best one. Many laptops use the programmable clock of the x chips at the console.

Also for non PCI machines specifying this force the linear base address to be this value, reprogramming the video processor to suit. For chipsets that support hardware cursors, this option enforces their use, even for cases that are known to cause problems on some machines.


Many DSTN screens use frame acceleration to improve the performance of the screen. There are therefore a wide variety of possible forms for all options.

This has been reported on some configurations. If you have a problem with the acceleration and these options will allow you to isolation the problem. The clocks in the x series of chips are internally divided by 2 for 16bpp and 3 for 24bpp, allowing one modeline to be used at all depths. Option “NoAccel” This option will disable the use of any accelerated functions.

This option, selects an 18 bit TFT bus. This website is using cookies. Now the maximum memory clock is just the maximum supported by the video processor, not the maximum supported by the video memory.
