The only lines you need in the "Device" section of your xorg.conf file are: <verb> Section "Device" Identifier "Intel i740" Driver "i740" EndSection </verb> or let <tt>xorgconfig</tt> do this for you. However, if you have problems with auto-detection, you can specify: <itemize> <item>VideoRam - in kilobytes <item>DacSpeed - in MHz <item>MemBase - physical address of the linear framebuffer <item>IOBase - physical address of the memory mapped IO registers </itemize> <sect>Driver Options <itemize> <item>"NoAccel" - Turn off hardware acceleration <item>"SWCursor" - Request a software cursor (hardware is default) <item>"SDRAM" - Force the use of SDRAM timings <item>"SGRAM" - Force the use of SGRAM timings <item>"SlowRam" - Force the use of slower ram timings <item>"Dac6Bit" - Force the use of a 6 Bit Dac (8 Bit is the default) <item>"UsePIO - Force the use of programmed IO (Memory mapped is the default) </itemize> Note: the i740 X server should automatically detect whether your card has SGRAM or SDRAM. Use the "sgram" and "sdram" options if it is incorrectly detected. <sect>Known Limitations <itemize> <item>Certain drawing operations are very slow when using 24 bit pixel depth mode. </itemize> <sect>Author <itemize> <item>Original version by Kevin E Martin <email>kevin@@precisioninsight.com</email> <item>Daryll Strauss <email>daryll@@precisioninsight.com</email> </itemize> The X11R&relvers; version of this driver originally came from XFree86 4.4 rc2.
