Usage:
$0 [options]
where options are:
-c, --host-cursor Uses host-cursor, otherwise uses Xephyr's.
-d, --dpi=NUMBER states the dots-per-inch to be used.
-s, --screen=SPEC WIDTHxHEIGHT[xDEPTH] to be used.
-x, --fxs=WxH+X+Y Fake xinerama screen resolution
(can be applied repeatedly)
-ax 2x3 Automatic set of fake xineramas, 2 horizontal
screens per 3 of vertical ones
-p, --profile=NAME Enlightenment profile name.
-e, --empty-home[=PATH] Run with \$HOME being a new, empty directory at /tmp
Debugger options:
--valgrind=MODE Run under valgrind to check for memory problems.
Same value as enlightenment_start, mode is "OR" of:
1 = plain valgrind to catch crashes (default)
2 = trace children (thumbnailer, efm slaves, ...)
4 = check leak
8 = show reachable after processes finish.
all = all of above
--valgrind-log-file=FILENAME
Save valgrind log to file, see valgrind's
--log-file for details.
--massif Run under massif valgrind tool.
--callgrind Run under callgrind valgrind tool.
Misc options:
-v, --verbose Be verbose about what is being done.
-h, --help Show this help.
Useful or common options:
--dpi=142 --screen=240x320x16
--dpi=142 --screen=320x240x16
--dpi=186 --screen=272x480x16
