In this case the driver divides the video processors dotclock limitation by the number of bytes per pixel, so that the limitations for the various colour depths are. This sets the default pixel value for the YUV video overlay key. It is completely ignored for HiQV chipsets. For the HiQV series of chips, the memory clock can be successfully probed. The HiQV chipsets contain a multimedia engine that allow a 16bpp window to be overlayed on the screen.

Chips and Technologies 65550 PCI BUS Drivers
The servers solution to this problem is not to do doubling vertically. The ” FixPanelSize ” can be used to force the modeline values into the panel size registers. Similar to the but also incorporates “PanelLink” drivers. This option is only useful when acceleration can’t be used and linear addressing can be used.

However there are many older machines, particularly those with x screen or larger, that need to reprogram the panel timings. XFree86 believes that the 8bpp framebuffer is overlayed on the 16bpp framebuffer. A ” letterbox ” effect with no stretching can be achieved using this option.
By default it is assumed that there are 6 significant bits in the RGB representation tecynologies the colours in 4bpp and above. In addition to this many graphics operations are speeded up using a ” pixmap cache “.
Which results in the x mode only expanded to x Using this option, when the virtual desktop is scrolled away from the zero position, the pixmap cache becomes visible. This sets the physical memory base address of the linear framebuffer.
This chip is similar to thebut it also includes XRAM support and supports the higher dot clocks of the technologiws Try deleting theses options from xorg. The effect of this problem will be that the lower part of the screen will reside in the same memory as the frame accelerator and will therefore be corrupt. Hardware cursors effectively speeds all graphics operations technologoes the job of ensuring that the cursor remains on top is now given to the hardware. For CRT’s you can also try to tweak the mode timings; try increasing the second horizontal value somewhat.
However some video ram, particularly EDO, might not be fast enough to handle this, resulting in drawing errors on the screen. With this option all of the graphics are rendered into a copy of the framebuffer that is keep in the main memory of the computer, and the screen is updated from this copy. The correct options to start the server with these modes are.
If you see such display corruption, and you have this warning, your choices are to reduce the refresh rate, colour depth or resolution, or increase the speed of the memory clock with the the ” SetMClk ” option described above. However these numbers take no account of the extra bandwidth needed for DSTN screens.
Information for Chips and Technologies Users
This is a driver limitation that might be relaxed in the future. For instance, the line.
Try a lower dot clock. Now the maximum memory clock is just the maximum supported by the video processor, not the maximum supported by the video memory. For LCD modes, it is possible that your LCD panel requires different panel timings at the text console than with teechnologies graphics mode.
Firstly, the memory requirements of both heads must fit in the available memory. When the chipset is capable of linear addressing and it has been turned off by default, this option can be used to turn it back on.
It should be noted that the dual channel display options of the require the use yechnologies additional memory bandwidth, as each display channel independently accesses the video memory. Options related to drivers can be present in the Screen, Device and Monitor sections and the Display subsections. For 24bpp on TFT screens, the server assumes that a 24bit bus is being used.
There are therefore a wide variety of possible forms for all options. The x and WinGine chipsets are capable of colour depths of techologies or 24bpp. For x chipsets the server assumes that the TFT bus width is 24bits. There is the limit of the maximum dotclock the video processor can handle, and there is another limitation of the available memory bandwidth.
The server doesn’t prevent the user from specifying a mode that will use this memory, it prints a warning on the console.
