Try reducing the clock. This also gives more memory bandwidth for use in the drawing operations. It also reduces the effect of cursor flashing during graphics operations. This is useful to see that pixmaps, tiles, etc have been properly cached. None of these are currently supported within the driver itself, so many cards will only have limited support. This is a very similar chip to the

Try deleting theses options from xorg. So using this option on a chups chipset forces them to use MMIO for all communications. Typically this will give you some or all of the clocks On a cold-booted system this might be the appropriate value to use at the text console see the ” TextClockFreq ” optionas many flat panels will need a dot clock different than the default to synchronise.

The server tevh then allow the mode to occupy the whole x LCD. This option sets the centering and stretching to the BIOS default values.

Audio facilities are ensured by the integrated 7. The memory bandwidth is determined by the clock used for the video memory. Many DSTN screens use frame acceleration to improve the performance of the screen.


There is no facility in the current Xservers to specify these values, and so the server attempts to read the panel size from the chip.

The server will limit the maximum dotclock to a value as specified by the manufacturer. Firstly, the memory requirements of both heads must fit in the available memory. For x chipsets the pi assumes that the TFT bus width is 24bits. Using this option, when the virtual desktop is scrolled away from the zero position, the pixmap cache becomes visible.

The servers solution to this problem is not to do doubling vertically. As use of the HiQV chipsets multimedia engine was tecb to be for things like zoomed video chipw, its use was supposed to be occasional and so most machines have their memory clock set to a value that is too high for use with the ” Overlay ” option. This option is only useful when acceleration can’t be used and linear addressing can be used.

The ct chipset introduced a new dual channel architecture. Therefore the server uses a default value of This is usually due to a problem with the ” LcdCenter ” option. Firstly, the ct chipset must be installed on a PCI bus.

Try reducing the amount of memory consumed by the mode. Download free driver for Chips and Tech. Search for drivers by ID or device name Known devices: Like the overlays, the Xvideo extension uses a part of the video memory for a second framebuffer. So this limit will be either 56MHz or 68MHz for the xx chipsets, depending on what voltage they are driven with, or 80MHz for the Chjps machines.


These options can be used to force a particular clock index to be used. This has a pxi effect depending on the hardware on which it is used.

Try a lower dot clock. No affiliation or endorsement is tec or implied. You can avoid this by either using the ” NoStretch ” option or removing the HWcursor ” option.

Driver for Chips and Tech. For 24bpp on TFT screens, the server assumes that a 24bit bus is being used.

However there are many differences at a register level. You can use the ” SetMClk ” option in your xorg. You have been warned! Lci overlay consumes memory bandwidth, so that the maximum dotclock will be similar to a 24bpp mode.
