The user can force the panel timings to be recalculated from the modeline with this option. Dual refresh rate display can be selected with the ” DualRefresh ” option described above. Hence you will see a line like. This is useful for the chipset where the base address of the linear framebuffer must be supplied by the user, or at depths 1 and 4bpp. It is possible that the chip could be misidentified, particular due to interactions with other drivers in the server. This support can be used to give a single display image on two screen with different refresh rates, or entirely different images on the two displays.

When constructing a modeline for use with the Chips and Technologies driver you’ll needed to considered several points. Leaving too little memory available for the cache will only have a detrimental effect on the graphics performance. As use of the HiQV chipsets multimedia engine was supposed to be for things like zoomed video overlays, 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 is useful to see that pixmaps, tiles, etc have been properly cached. A similar level of acceleration to the is included for this driver. Try reducing the clock. If the screen is using a mode that BIOS doesn’t know about, then there is no guarantee that it will be resumed correctly. The Xorg X server, allows the user to do damage to their hardware with software with old monitors which may not tolerate bad display settings. A sample of an incomplete ” xorg. The whole thing is divided by the bytes per pixel, plus an extra byte if you are using a DSTN.
However the panel size will still be probed. 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.
This option forces the LCD panel size to be overridden by the modeline display sizes. You are using a mode that your screen cannot handle. This is usually due to a problem with the ” LcdCenter ” option. Using an 8bpp, the colour will then be displayed incorrectly. If you get pixel error with this option try using the ” SetMClk ” option to slow the memory clock. Most of the Chips and Technologies chipsets are supported by this driver to some degree.
Display might be corrupted!!! The and have a 64bit memory bus and technplogies transfer 8 bytes every clock thus hence the 8while the other HiQV chipsets are 32bit and transfer 4 bytes per clock cycle hence the 4.

This option might also be used to reduce the speed of technologiez memory clock to preserve power in modes that don’t need the full speed of the memory to work correctly.
The authors of this software wish to acknowledge the support supplied by Chips and Technologies during the development of this software.
Try reducing the amount of memory consumed by the mode. It is completely ignored for HiQV chipsets. The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel clocks, where the options above set the clocks to 65MHz.
If this is a problem, a work around is to remove the ” HWcursor ” option.
This chip is similar to the but has a 64bit memory bus annd opposed to a 32bit bus. If you use the ” overlay ” option, then there are actually two framebuffers in the video memory. For the HiQV series of chips, the memory clock can be successfully probed.

Note that it is overridden by the ” SWcursor ” option. Try a lower dot clock. You are probably using a dot clock that is too high or too low ; it is also possible that there is interference with a close MCLK. This allows the user to select a different clock for the server to use when returning chip the text console.

Many DSTN screens use frame acceleration to improve the performance of the screen. See ct for details. This has a different effect depending on the hardware on which it is used.
