These options can be used to force a particular clock index to be used. 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. The server will limit the maximum dotclock to a value as specified by the manufacturer. Note that linear addressing at 1 and 4bpp is not guaranteed to work correctly. As mentioned before, try disabling this option. The xx MMIO mode has been implemented entirely from the manual as I don’t have the hardware to test it on.

This is the first chip of the ctxx series to support fully programmable clocks.

See ct for details. These apps will allow you to check your Internet speed, get a PC backup and even tune-up your PC performance. The default behaviour is to have both the flat panel and the CRT use the same display channel and thus the same refresh rate. It is possible that the chip could be misidentified, particular due to interactions with other drivers in the server.

Similar to the but has yet higher maximum memory and tecbnologies clocks.

This is a more advanced version of the Technolohies chip, with specification very similar to the x series of chips. XFree86 believes that the 8bpp framebuffer is overlayed on the 16bpp framebuffer. This has been reported on some configurations. If the colours seem darker than they should be, perhaps your ramdac is has 8 significant bits.


Dual-head display has two effects on the modelines. It might affect some other SVR4 operating systems as well. Technologied “NoAccel” This option will disable the use of any accelerated functions. Most of the Chips and Technologies chipsets are supported by this driver to some degree. If you exceed the maximum set by the memory clock, you’ll get corruption on the screen during graphics operations, as you will be starving the HW BitBlt engine of clock cycles.

This can result in a reddish tint to 24bpp mode. Microsoft and Windows are registered trademarks of Microsoft Corporation. For Technologiws screens, the lowest clock that gives acceptable contrast and flicker is usually the best one.

Some machines that are known to need these options include. These option individually disable the features of the XAA acceleration code that the Chips and Technologies driver uses. The server itself can correctly detect the chip in the same situation. This will prevent the use of tefhnologies mode that is a different size than the panel. The programmable clock makes this option obsolete and so it’s use isn’t recommended. Display might be corrupted!!!

This shouldn’t affect higher depths, and is fixable with a switch to the virtual console and back. It checks everything such as sound card, graphic card, monitor, mouse, printer, etc.

It overrides the options “LcdCenter” and “NoStretch”. Work is underway to fix this. 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.

This also gives more memory bandwidth for use in the drawing operations. Firstly, the ct chipset must be installed on a PCI bus. This option, selects an 18 bit Technoogies bus. However the panel size will still be probed.

It should be noted that if a flat panel is used, this it must be allocated to ” Screen 0 “. The xx MMIO mode has been implemented entirely from the manual as I don’t have the hardware to test it on.
