You are using a mode that your screen cannot handle. For LCD modes, it is possible that your LCD panel requires different panel timings at the text console than with a graphics mode. This also gives more memory bandwidth for use in the drawing operations. Note that many chips are capable of higher memory clocks than actually set by BIOS. Chips and Technologies specify that the memory clock used with the multimedia engine running should be lower than that used without. This may be related to a bug in one of the accelerated functions, or a problem with the BitBLT engine. The whole thing is divided by the bytes per pixel, plus an extra byte if you are using a DSTN.

Similar to the but also incorporates “PanelLink” drivers.

Which results in the x mode only expanded to x The forms given below are the preferred forms. This option forces the server to assume that there are 8 significant bits.

This chip is basically identical to the This is a small and long-standing bug in the current server. You technoloyies probably using a dot clock that is too high or too low ; it is also possible that there is interference with a close MCLK.

However if you do try this option and are willing to debug it, I’d like to hear from you. The ct supports dual-head display. So the value actually used for the memory clock might be significantly less than this maximum value.

If this is a problem, a work around is to remove the ” HWcursor ” option. 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 WinGine machines.


If the screen is teechnologies a mode that BIOS doesn’t know about, then there is no guarantee that it will be resumed correctly. For the chips either using the WinGine or basic architectures, the chips generates a number of fixed clocks internally.

By default the two display share equally the available memory. The XVideo tedhnologies has only recently been added to the chips driver. For chipsets that support hardware cursors, this option enforces their use, even for cases that are known to cause problems on some machines.

By default it is assumed that there are 6 significant bits in the RGB representation of the colours in 4bpp and above. In this case the driver divides the video processors dotclock limitation by the number of bytes per pixel, so that the limitations for the various colour depths are. The xx MMIO mode has been implemented entirely from the manual as I don’t have the hardware to test it on. This might cause troubles with some applications, and so this option allows the colour transparency key to be set to some other value.

The current programmable clock will be given as the last clock in the list.

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. 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 “.


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.

With this option all of the graphics are rendered into a copy of the framebuffer that is keep in the main memory of the computer, and the screen is updated from this copy.

Additionally, the ” Screen ” option must appear in the device section. If it is a non-standard mode, maybe you need to tweak the timings a bit.

So the driver will attempt to round-up the virtual X dimension to a multiple of 64, but leave the virtual resolution untouched. The server will limit the maximum dotclock to a value as specified by the manufacturer.

One the overall maximum, and another due to the available memory bandwidth technilogies the chip. Note that technoloyies the this is required as the base address can’t be correctly probed. Like the overlays, the Xvideo extension uses a part of the video memory for a second framebuffer. In general the LCD panel clock should be set independently of the modelines supplied. The programmable clock makes this option obsolete and so it’s use isn’t recommended.
