However there is no reliable way of probing the memory clock used in these chipsets, and so a conservative limit must be taken for the dotclock limit. However use caution with these options, because there is no guarantee that driving the video processor beyond it capabilities won’t cause damage. This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card. This reduces the amount of video ram available to the modes. An 8bpp one and a 16bpp one.

In fact the timing for the flat panel are dependent on the specification of the panel itself and are independent of the particular mode chosen. If the screen is using a mode that BIOS doesn’t know about, then there is no guarantee that it will be resumed correctly. Further to this some of the XAA acceleration requires that the technolobies pitch is a multiple of 64 pixels.

Now the maximum memory clock is just the maximum supported by the video processor, not technologiies maximum supported by the video memory. So the driver will attempt to round-up the virtual X dimension to a multiple of 64, but leave the virtual resolution untouched.

For other screen drawing related problems, try the ” NoAccel ” or one of the XAA acceleration options discussed above. Normally the colour transparency key for the overlay is the 8bpp lookup table entry This is useful to see that pixmaps, tiles, etc have been properly cached.


With the chips and later or thethe default is to use the programmable clock for all clocks. The server doesn’t prevent the user from specifying a mode that will use this memory, it prints a warning on the console.

This has been reported on some configurations. Hence the server assumes a In this case the driver divides the video processors dotclock limitation by the number of bytes per pixel, technologie that the limitations for the various colour depths are. This technologeis means that there are two limits on the dotclock. A ” letterbox ” effect with no stretching can be achieved using this option. Using these should give you all the capabilities you’ll need in the server to get a particular mode to work.

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 technoloties all depths. Option “NoAccel” This option will disable the use of any accelerated functions.

XFree86 releases later than 4. The chipset tecnologies independent display channels, that can be configured to support independent refresh rates on the flat panel and on the CRT. Options related to drivers can be present in the Screen, Device and Monitor sections and the Display subsections.

If this option is removed form xorg.

If it is a standard mode and frequency that your screen should be able to handle, try to find different timings for a similar mode and frequency combination. You are using a mode that your screen cannot handle. You can avoid this by either using the ” NoStretch ” option or removing the HWcursor ” option. Typical values for the size of the framebuffer will be bytes x panelbytes x panel and bytes x panel. The server itself can correctly detect the chip in the same situation.


Try reducing the amount of memory consumed by the mode. Note that many chips are capable of higher memory clocks than actually set by BIOS. Hi-Color and True-Color modes are implemented in the server.

Otherwise it has the the same properties as the The HiQV series of chips doesn’t need to use additional clock cycles to display higher depths, and so the same modeline can be used at all depths, without needing to divide the clocks. The xx chipsets can use MMIO technologiew all communications with the video processor.

However careful use of this option might boost performance.

technologied The amount of ram required for the framebuffer will vary depending on the size of the screen, and will reduce the amount of video ram available to the modes.
