It is derived from the .I X386 server provided with X11R5. Note: 16-bit TrueColor is currently only supported for some Cirrus and ARK chips, and 24-bit TrueColor is only supported for some Cirrus chips. .SH CONFIGURATIONS .PP The .I XF86_SVGA server supports the following popular SuperVGA chipsets in 256 color mode. Virtual resolutions up to (approximately) 1152x900 are supported, using (up to) 1Mb of display memory. The Western Digital WD90C33 and some of the Cirrus chipsets support up to 2Mb of display memory and virtual resolutions of 1280x1024 and higher. Some of the Cirrus chipsets also support 16bpp and 32bpp (truecolor) modes on certain configurations. Some of the ARK chipsets support 16bpp modes on certain configurations. Generic VGA cards are also supported at 8bpp 320x200 only. .RS .5i .TP 4 ATI: 18800, 18800-1, 28800-2, 28800-4, 28800-5, 28800-6, 68800-3, 68800-6, 68800AX, 68800LX, 88800CX, 88800GX .TP 4 Tseng: ET3000, ET4000, ET4000/W32 .TP 4 Western Digital: PVGA1, WD90C00, WD90C10, WD90C11, WD90C24A, WD90C30, WD90C31, WD90C33 .TP 4 Genoa: GVGA .TP 4 Trident: TVGA8800CS, TVGA8900B, TVGA8900C, TVGA8900CL, TVGA9000 .TP 4 NCR: 77C22, 77C22E .TP 4 Cirrus Logic: CLGD5420, CLGD5422, CLGD5424, CLGD5426, CLGD5428, CLGD5429, CLGD5430, CLGD5434, CLGD5436, CLGD6205, CLGD6215, CLGD6225, CLGD6235, CL6410, CL6412, CL6420, CL6440 .TP 4 ARK: ARK1000PV, ARK1000VL, ARK2000PV .TP 4 RealTek: RTG3106 .TP 4 Compaq: AVGA .TP 4 Oak: OTI067, OTI077, OTI087 .TP 4 Avance Logic: AL2101, ALI2301, ALI2302, ALI2308, ALI2401 .TP 4 Chips & Technology: .ig 82C451, 82C452, 82C453, 82C455, 82C456, 82C457, .. 65520, 65530, 65540, 65545 .TP 4 MX:\ \ MX68000, MX68010 .TP 4 Video7: HT216-32 .RE .PP Accelerated support is included for most of the Cirrus chipsets, and for the Western Digital WD90C31 and WD90C33 chipsets. Accelerated support for the ET4000/W32 is implemented in a separate server (see \fIXF86_W32(1)\fP). Users of boards based on ATI's Mach8, Mach32 and Mach64 chipsets should refer to the \fIXF86_Mach8(1)\fP, \fIXF86_Mach32(1)\fP and \fIXF86_Mach64(1)\fP manual pages, respectively. .SH OPTIONS In addition to the normal server options described in the \fIXserver(1)\fP manual page, \fIXF86_SVGA\fP accepts some more command line switches, as described in the .I XFree86(1) manpage. .SH SETUP .I XFree86 uses a configuration file called \fBXF86Config\fP for its initial setup. See the .I XF86Config(4/5) manpage for general details. Here only the .I XF86_SVGA specific parts are explained. .PP This server requires a \fBScreen\fP section in the XF86Config file with the \fBDriver\fP entry set to \fBsvga\fP. .PP Entries for the \fBDevice\fP section in the XF86Config file include: .br .ne 3i .TP 8 .B chipset \fI"name"\fP specifies a chipset so the correct driver can be used. Possible chipsets are: .sp .RS 1.5i .TP 4 ATI: vgawonder .TP 4 Tseng: et3000, et4000, et4000w32, et4000w32i, et4000w32p .TP 4 Western Digital: pvga1, wd90c00, wd90c10, wd90c24, wd90c30, wd90c31, wd90c33 .TP 4 Genoa: gvga .TP 4 Trident: tvga8800cs, tvga8900b, tvga8900c, tvga8900cl, tvga9000 .TP 4 NCR: ncr77c22, ncr77c22e .TP 4 Cirrus Logic: clgd5420, clgd5422, clgd5424, clgd5426, clgd5428, clgd5429, clgd5430, clgd5434, clgd5436, clgd6205, clgd6215, clgd6225, clgd6235, cl6410, cl6412, cl6420, cl6440 .TP 4 RealTek: realtek .TP 4 ARK: ark1000pv, ark1000vl, ark2000pv .TP 4 Compaq: cpq_avga .TP 4 OAK: oti067, oti077, oti087 .TP 4 Avance Logic: al2101, ali2301, ali2302, ali2308, ali2401 .TP 4 Chips & Technology: .ig ct451, ct452, ct453, ct455, ct456, ct457, .. ct65520, ct65530, ct65540, ct65545 .TP 4 MX:\ \ mx .TP 4 Video7: video7 .TP 4 Generic: generic .RE .TP 8 .B Option \fI"optionstring"\fP allows the user to select certain options provided by the drivers. Currently the following strings are recognized: .sp \fBlegend\fP - for Sigma Legend ET4000-based boards. This option enables a special clock-selection algorithm used on Legend boards, and MUST be specified for these boards to function correctly. .sp \fBswap_hibit\fP - for Western Digital/PVGA1 chipsets. Some Western Digital based boards require the high-order clock-select lead to be inverted. It is not possible for the server to determine this information at run-time. If the 9th clock in the list of clocks detected by the server is less than 30Mhz, this option likely needs to be set. .sp \fBhibit_low\fP, \fBhibit_high\fP - for Tseng ET4000 chipsets. With some ET4000 cards, the server has difficulty getting the state of the high-order clocks select bit right when started from a high-resolution text mode. These options allow the correct initial state of that bit to be specified. To find out what the correct initial state is, start the server from an 80x25 text mode. This option is only needed if the clocks reported by the server when started from a high-resolution text mode differ from those reported when it is started from an 80x25 text mode. .sp \fB8clocks\fP - for the PVGA1 chipset the default is 4 clocks. Some cards with this chipset may support 8 clocks. Specifying this option will allow the driver to detect and use the extra clocks. .sp \fB16clocks\fP - for Trident TVGA8900B and 8900C chipsets. Some newer boards using 8900B and 8900C chipsets actually support 16 clocks rather than the standard 8 clocks. Such boards will have a "TCK9002" or "TCK9004" chip on them. Specifying this option will allow the driver to detect and use the extra 8 clocks. .sp \fBprobe_clocks\fP - for Cirrus chipsets. The Cirrus driver has a fixed set of clocks that are normally used. Specifying this option will force the driver to probe for clocks instead of reporting the built-in defaults. This option is for debugging purposes only. .sp \fBpower_saver\fP - This option enables the server to use the power saving features of VESA DPMS compatible monitors. The suspend level is currently not supported. Refer to the \fIXF86Config(4/5)\fP manual page for details of how to set the timeouts for the different levels of operation. This option is experimental. .sp \fBnoaccel\fP - for Cirrus and WD chipsets. This option disables the accelerated features for the clgd5426, clgd5428, wd90c24, wd90c31 and wd90c33 chipsets. .sp \fBfifo_conservative\fP - for Cirrus chipsets. This option sets the CRT FIFO threshold to a conservative value for dot clocks above 65MHz. This reduces performance, but may help in eliminating problems with ``streaks'' on the screen during BitBLT operations .sp \fBfifo_aggressive\fP - for Cirrus chipsets. This option sets the CRT FIFO threshold to an aggressive value for dot clocks above 65MHz. This may increase performance. .sp \fBslow_dram\fP - for Cirrus chipsets. This option sets the DRAM timings for slow DRAM chips. .sp \fBfast_dram\fP - for ET4000 and Cirrus chipsets. This option sets the DRAM timings for fast DRAM chips. .sp \fBno_2mb_banksel\fP - for Cirrus chipsets. This option is required for Cirrus cards with 2MB of videoram which is in the form of 512kx8 DRAMs (4 chips) rather than 256kx4 DRAMs (16 chips). .sp \fBno_bitblt\fP - for Cirrus chipsets. This option disables use of hardware BitBLT. .sp \fBlinear\fP - Attempt a linear mapping of the framebuffer into high memory. Currently only supported for some Cirrus configurations. .sp \fBmed_dram, favour_bitblt, sw_cursor, clgd6225_lcd, mmio\fP - more Cirrus-specific options. Refer to /usr/X11R6/lib/X11/doc/README.cirrus for a detailed description of Cirrus options. .ig intern_disp (use internal display for laptops -- WD90C2x) extern_disp (use external display for laptops -- WD90C2x) .. .TP 8 .B speedup \fI"selection"\fP sets the selection of SpeedUps to use. The optional selection string can take the following values: .sp .in 20 .nf none all .fi .IP If the selection string is omitted, or if the \fBspeedup\fP option is omitted, the selection defaults to "all". Some of the SpeedUps can only be used with the ET4000, WD90C31 and WD90C33 chipsets and others requires a virtual resolution with a xdim of 1024. SpeedUps that won't work with a given configuration are automatically disabled. .TP 8 .B nospeedup disables the SpeedUp code. This is equivalent to \fBspeedup "none"\fP. .TP 8 .B Ramdac \fI"ramdac-type"\fP This specifies the type of RAMDAC used on the board. Only the ARK driver currently uses this. RAMDAC types recognised include: .sp \fBatt20c490\fP - AT&T 20C490 or compatible 8-bit RAMDAC. .sp \fBatt20c498\fP - AT&T 20C498 or compatible 16-bit RAMDAC. .sp \fBzoomdac\fP - RAMDAC used by the Hercules Stingray Pro/V and 64/V. .sp \fBstg1700\fP - STG1700 or compatible RAMDAC. .PP Note that \fIXFree86\fP has some internal capabilities to determine what hardware it is running on. Thus normally the keywords \fIchipset\fP, \fIclocks\fP, and \fIvideoram\fP don't have to be specified. But there may be occasions when this autodetection mechanism fails, (for example, too high of load on the machine when you start the server). For cases like this, one should first run \fIXF86_SVGA\fP on an unloaded machine, look at the results of the autodetection (that are printed out during server startup) and then explicitly specify these parameters in the configuration file. \fBIt is recommended that all parameters, especially Clock values, be specified in the XF86Config file.\fP .SH FILES .TP 30 /bin/XF86_SVGA The SVGA color X server .TP 30 /etc/XF86Config Server configuration file .TP 30 /lib/X11/XF86Config Server configuration file .TP 30 /lib/X11/doc/README.ark Extra documentation for the ARK driver .TP 30 /lib/X11/doc/README.ati Extra documentation for the ATI vgawonder driver .TP 30 /lib/X11/doc/README.cirrus Extra documentation for the Cirrus driver .TP 30 /lib/X11/doc/README.trident Extra documentation for the Trident driver .TP 30 /lib/X11/doc/README.tseng Extra documentation for the ET4000 and ET3000 drivers .TP 30 /lib/X11/doc/README.Oak Extra documentation for the Oak driver .TP 30 /lib/X11/doc/README.Video7 Extra documentation for the Video7 driver .TP 30 /lib/X11/doc/README.WstDig Extra documentation for the WD/PVGA driver .LP Note: refers to the root of the X11 install tree. .SH "SEE ALSO" X(1), Xserver(1), XFree86(1), XF86Config(4/5), xf86config(1), xvidtune(1), xdm(1), xinit(1) .SH BUGS .PP Bug reports are welcome, and should be emailed to the address listed below. .SH CONTACT INFO \fIXFree86\fP source is available from the FTP server \fIftp.XFree86.org\fP.
