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. Many DSTN screens use the top of video ram to implement a frame accelerator. The forms given below are the preferred forms. In general there are two factors determining the maximum dotclock. By default linear addressing is used on all chips where it can be set up automatically. In addition the device, screen and layout sections of the ” xorg. Return to General Old Hardware.

Information for Chips and Technologies Users
This is a debugging option and general users have no need of it. It also has higher limits on the maximum memory and pixel clocks Max Ram: The xx MMIO mode has been implemented entirely from the manual as I don’t have the hardware to test it on. If you chpis a problem with the acceleration and these options will allow you to isolation the problem.
Kinda funny, I shoulda figured that. It has the same ID and is identified as a when probed. I’ll edit this post once I have.
For some machines the LCD panel size is incorrectly probed from the registers. Try deleting theses options from xorg. The whole thing is divided by the bytes per pixel, plus an extra byte if you are using a 6555. Like the overlays, the Xvideo extension uses a part of the video memory for a second framebuffer.
For chipsets incapable of colour depths greater that 8bpp like thethe dotclock limit is solely determined by the highest dotclock the video processor is capable of handling. There is no material that is knowingly illegal here.

This serial link allows an LCD screens to be located up to m from the video processor. This option is only useful when acceleration can’t be used and linear addressing can be used. If this is not true then the screen will appear to have a reddish tint.
It also includes a fully programmable dot clock and supports all types of flat panels. Yeah, I’d doublecheck with various utilities that the chip is being detected and identified correctly?

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. So the driver will attempt to round-up the virtual X dimension to a multiple of 64, hcips leave the virtual resolution untouched.
The total memory requirements in this mode of operation is therefore similar to a 24bpp mode. Horizontal waving or jittering of the whole screen, continuously independent from drawing operations.
There has been much confusion about exactly what the clock limitations of the Chips and Cuips chipsets are.
Use caution as excess heat generated by the video processor if its specifications are exceeded might cause damage. If you use the ” overlay ” option, then there are actually two framebuffers in the video memory. 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 you find you truly can’t achieve the mode you are after with the default clock limitations, look at the options ” DacSpeed ” and ” SetMClk “. In this way the expensive operation of reading back to contents of the screen is never performed and the performance is improved.
This option might be used if the default video overlay key causes problems.
Note that the reverse is also true. This will prevent the use of a mode that is a different size than the panel.
See ct for details. This option, selects an 18 bit TFT bus. 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. The and have a 64bit memory bus and thus 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 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.
