The current options for the XServer produce a huge amount of log messages. The server produces around 70-80 messages per minute. The most messages look like this: display-manager-start[1846]: GetModeLine - scrn: 0 clock: 75200 display-manager-start[1846]: GetModeLine - hdsp: 1366 hbeg: 1414 hend: 1478 httl: 1582 display-manager-start[1846]: vdsp: 768 vbeg: 772 vend: 779 vttl: 792 flags: 9 Since theses messages aren't very useful, I propose to remove the `-logverbose` and `-verbose` options from the XServer arguments.
