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. These options can be used to force a particular clock index to be used. We recommend that you try and pick a mode that is similar to a standard VESA mode. You may notice that the file size of the installer software is much smaller than the file size of your actual driver. For this reason it is recommended to use one of the programs that automatically generate xorg.

Note that many chips are capable of higher memory clocks than actually set by BIOS. You are using a mode that your screen cannot handle. Note that this option only has an effect on TFT screens. The server doesn’t prevent the user from specifying a mode that will use this memory, it prints a warning on ane console.

Ane shouldn’t affect higher depths, and is fixable with a switch to the virtual console and back. Possibly useful if you wish to use an old workstation monitor. So using this option technoloties the XVideo extension. If it is a standard mode and frequency that your screen should be able to handle, try to find different timings for a similar mode and frequency combination.

Secondly, the memory bandwidth technopogies the video processor is shared between the two heads. 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. Using this option the mode can be centered in the screen. Note fechnologies all of the chips except the rev A are 3. 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.


The clock code can be fooled into giving a different and perhaps more stable clock by simply changing the clock value slightly.

The flat panel timings are related to the panel size and not the size of the mode specified in xorg. This sets the default pixel value for the YUV video overlay key. This driver uses this capability to include a 16bpp framebuffer on top of an 8bpp framebuffer.

The chipset has independent display channels, that can be configured to support independent refresh rates on the flat panel and on the CRT. The server will limit the maximum dotclock to a value as specified by the manufacturer. It overrides the options “LcdCenter” and “NoStretch”. 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.

As chhips before, try disabling this option. This option might also be needed to reduce the speed of the memory clock with the ” Overlay ” option. This information will be invaluable in debugging any problems. The default behaviour is to have both the flat panel and the CRT use the same display channel and thus the same refresh rate. However careful use of this option might boost performance. Sometimes anti-virus software can report false positives.


However the panel size will still be probed. Horizontal waving or jittering of the whole screen, continuously independent from drawing operations.

Otherwise it has the the same properties as the Hardware cursors effectively speeds all graphics operations as the job of ensuring that the cursor remains on top is now given to the hardware. For this technologiea a mode that is as close to VESA like as possible should be selected.

However, as the driver does not prevent you from using a mode that will exceed the memory bandwidth of thebut a warning like. Before using this check that the server reports an incorrect panel size. In fact the timing for the flat panel are dependent on the specification of the panel itself and are independent of the particular mode chosen. Hi-Color and True-Color modes are implemented in the server.

Technolgoies you are driving the video memory too fast too high a MemClk you’ll get pixel corruption as the data actually written to the video memory is corrupted by driving the memory too fast.
