This is more for the list than you Mark, as you know this of course. ;o) The X server has a plethora of ways of indicating the same boolean meaning: Option "swcursor" Option "SWcursor" Option "swcursor" "yes" Option "sw cursor" "TRUE" Option "hwcursor" "false" Option "hwcursor" "no" Option "NoHwcursor" Option "s W___________c___ u__R S or" "Y e S" all of the above options should do the exact same thing, and enable software cursor (or disable hardware cursor depending on your perspective). Likewise, similar options for hwcursor will enable it. The majority of drivers default to using the hardware cursor in all cases, however some of them default to using swcursor either due to hardware cursor limitations, or bugs in the hardware cursor code in the driver, sometimes just for one chip. The colour ARGB cursors add a new twist to this as well, as some hardware simply doesn't support using ARGB cursors in hardware cursor mode. Without specifying "swcursor" nor "hwcursor" you'll generally get hardware cursors if the driver supports it on your hardware and doesn't disable it due to hardware limitations or broken driver workaround hacks. If you're using the new colour mouse cursors, then wether you get hardware cursors or not depends on the driver and chip also. Since you might get hardware or software cursors by default depending on the variety of variables involved, both of the "hwcursor" and "swcursor" options make sense in a general X server sense. As a human, I think "I want hardware cursors" or "I want software cursors" rather than "I want hardware cursors" or "I want no hardware cursors". Also, removing one of the two options from XFree86 would not really provide any benefit IMHO, and it would break config file compatibility and a lot of pre-existing usage. If it were deemed that this was the way to go anyway, and one of the two options were to be eliminated across the server and all drivers as a whole, I would only find that rational if all other options in the X server followed suit, and thus remove all redundant options at once. There is a lot of redundancy in the config file syntax. That was purported as a feature way back when I presume, and it's debateable wether or not it was a good thing or a bad thing I guess. ;o) Hopefully it doesn't change majorly between non-major X server generations, as that makes upgrades a PITA. ;o) -- Mike A.
