Try reducing the amount of memory consumed by the mode. 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 is a more advanced version of the WinGine chip, with specification very similar to the x series of chips. WW Memory bandwidth requirements exceeded by dual-channel WW mode. The server will then allow the mode to occupy the whole x LCD.

If you have a problem with the acceleration and these options will allow you to isolation the problem.
The programmable clock makes this option obsolete and so it’s use isn’t recommended. Try reducing the clock. Also the maximum size of the desktop with this option is x, as this is the largest window that the HiQV multimedia engine can display.

Dual refresh rate display can be selected with the ” DualRefresh ” option described above. By default the two display share equally the available memory. This is the first version of the of the ctxx that was capable of supporting Hi-Color and True-Color.
In addition to this many graphics cihps are speeded up using a ” pixmap cache “.
Hi-Color and True-Color modes are technologiies in the server. For other screen drawing related problems, try the ” NoAccel ” or one of the XAA acceleration options discussed above. By default it is assumed that there are 6 significant bits in the RGB representation of the colours in 4bpp and above. It is completely ignored for HiQV chipsets.

This can be found from the log file of a working single-head installation. Options related to drivers can be present in the Screen, Device and Monitor sections and the Display subsections. Except for the HiQV chipsets, it is impossible for the server to read the value of the currently used frequency technoligies the text console when using programmable clocks.
It also has higher limits on the maximum memory and pixel clocks Max Ram: Some users prefer to use clocks that are defined by their BIOS.
For this reason the default behaviour of the server is to use the panel timings already installed in the chip. In this case enough memory needs to be left for the largest unscaled video window that will be displayed. The x and WinGine chipsets are technologes of colour depths of 16 or 24bpp. Dual-head display has two effects on the modelines.
Composite sync on green. If the colours seem darker than they should be, perhaps your ramdac is has 8 significant bits. In this way the expensive operation of reading back to contents of the screen is never performed and the performance is improved.
Before using this check that the server reports an incorrect panel size. The ct supports dual-head display. So this limit will be either 56MHz or 68MHz for cchips xx chipsets, depending on what voltage they are driven with, or 80MHz for the WinGine machines. The XVideo extension has only recently been added to the chips driver.

In its current form, X can not take advantage of this second display channel. This might cause troubles with some applications, and so this option allows the colour transparency key to be set to some other value.
Therefore the server uses a default value of This is usually due to a problem with the ” LcdCenter ” option. However if you do try this option and are willing to debug it, I’d like to hear from you.
Therefore to use this option the server must be started in either 15 or 16bpp depth. Display might be corrupted!!!
