Dual refresh rate display can be selected with the ” DualRefresh ” option described above. The clocks in the x series of chips are internally divided by 2 for 16bpp and 3 for 24bpp, allowing one modeline to be used at all depths. Which is the reason for the drop in the dot clock. The clock code can be fooled into giving a different and perhaps more stable clock by simply changing the clock value slightly. The ” FixPanelSize ” can be used to force the modeline values into the panel size registers. However this version of the Chips and Technologies driver has many new features and bug fixes that might make users prefer to use this version. The server will then allow the mode to occupy the whole x LCD.

The reason for this is that the manufacturer has used the panel timings to get a standard EGA mode to work on 655554 panel, and these same timings don’t work for an SVGA mode. The Xserver assumes that the framebuffer, if used, will be at the top of video ram.

So with the ” Overlay ” option, using the ” SetMClk ” option to reduce the speed of the memory clock is recommended.

Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets. It often uses external DAC’s and programmable clock chips to supply additional functionally. But assuming your memory clock is programmed to these maximum values the various maximum dot clocks for the pcl are. So for unexplained problems not addressed above, please try to alter the clock you are using slightly, say in steps of 0.


It is enabled by default for machines since the blitter can not be used otherwise. This is useful to see that pixmaps, tiles, etc have been properly cached. If this option is removed form xorg.

Tecchnologies is a very similar chip to the In general the LCD panel clock should be set independently of the modelines supplied. Like the overlays, the Xvideo extension uses a part of the video memory for a second framebuffer. This option forces the second display to take a particular amount of memory.

Use caution with this option, as driving the video processor beyond its specifications might cause damage. This option allows the user to force the server the reprogram the flat panel clock independently of the modeline with HiQV chipset.

So using this option on a xx texhnologies forces them to use MMIO for all communications. It is completely ignored for HiQV chipsets. For other screen drawing related problems, try the ” NoAccel ” or one of the XAA acceleration options discussed above.

Firstly, the ct chipset must be installed on a PCI bus.

This might cause troubles with some applications, and so this technologie allows the colour transparency key to be set to some other value. Chips and Technologies specify that the memory clock used with cihps multimedia engine running should be lower than that used without. Hence the server assumes a When tschnologies 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 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.


For this reason the default behaviour of the server is to use the panel timings already installed in the chip. 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 chiips or resolution, or increase the speed of the memory clock with the the ” SetMClk ” option described above.

Dual-head display has two effects on the modelines. In addition to this many graphics operations are speeded up using a ” pixmap cache “. If you are having driver-related problems that are not addressed by this document, or if you have found bugs in accelerated functions, you can try contacting the Xorg team the current driver maintainer can be reached at eich freedesktop.

If this is not true then the screen will appear to have a reddish tint.

This has been reported on some configurations. It might affect some other SVR4 operating systems as well. The Xorg X server, allows the user to do damage to technologoes hardware with software with old monitors which may not tolerate bad display settings.
