For this reason a mode that is as close to VESA like as possible should be selected. The servers solution to this problem is not to do doubling vertically. The HiQV chipsets contain a multimedia engine that allow a 16bpp window to be overlayed on the screen. A ” letterbox ” effect with no stretching can be achieved using this option. 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. Using this option, when the virtual desktop is scrolled away from the zero position, the pixmap cache becomes visible. If you are having driver-related problems that are not addressed by this document, or if you have found bugs in accelerated functions, you can try contacting the Xorg team the current driver maintainer can be reached at eich freedesktop.

This also gives more memory bandwidth for use in the drawing operations. Discussion Thread Date; Chips and Technologies chips and tech.

Therefore to use this option the server must be started in either 15 or 16bpp depth. Firstly, the memory requirements of both heads must fit in the available memory. There gechnologies therefore a wide variety of possible forms for all options. However, some machines appear to have this feature incorrectly setup.
If this is not true then the screen will appear to have a reddish tint. This document attempts to discuss the features of this driver, the options useful in configuring it and the known problems.

The HiQV chipsets contain a multimedia engine that allow a 16bpp window to be overlayed on techhologies screen. 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 might further reduce the available memory. This shouldn’t affect higher depths, and is fixable with a switch to the virtual console and back.
However luckily there are many different clock register setting that can give the same or very similar clocks. For this reason the default behaviour of the server is to use the panel timings already installed in the chip. This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card. When the size of the mode used is less than the panel size, the default behaviour of the server is to align the left hand edge of the display with the left hand edge of the screen.
These option individually disable the features of the XAA acceleration code that the Chips and Technologies driver uses. The order of precedence is Display, Screen, Monitor, Device. The default behaviour is to have both the flat panel and the CRT use the same display channel and thus the same refresh rate. Alternatively the user can use the ” TextClockFreq ” option described above to select a different clock for the text console. This might make chipx modes impossible to obtain with a reasonable refresh rate.
86554 the authors of this software have tried to prevent this, they disclaim all responsibility for any damage caused by the software.
The Chips and Technologies driver release in X11R7. The amount of ram required for the tschnologies will vary depending on the size of the screen, and will reduce the amount of video ram available to the modes.
However there are many older machines, particularly those with x screen or larger, that need to reprogram the panel timings. Some users prefer to use clocks that are defined by their BIOS. Using an 8bpp, the colour will then be displayed incorrectly. In fact if the video BIOS on the machine sets techhologies ct to a dual channel mode by default, X will lockup hard at this point.
For the chips either using the WinGine or basic architectures, the chips generates a number of fixed clocks internally. This is a more advanced version technoloyies the WinGine chip, with specification very similar to the x series of chips.

Linear addressing is not supported for this card in the driver. The overlay consumes memory bandwidth, so that the maximum dotclock will be similar to a 24bpp mode. Option “NoAccel” This option will disable the use of any accelerated functions. Because the rendering is all done into a virtual framebuffer acceleration can not be used. Technologjes is completely ignored for HiQV chipsets.
This option sets the centering and stretching to technllogies BIOS default values.
