The Trace Tab

Options that you can specify within this tab are for debug purposes. They exert influence on all X applications of the package (XServer, X Clients, etc ...).

Keyboard trace level

A value (one from None, Minimal, Advanced, Full) in this field denotes a tracing level for collecting keyboard trace information for your X-session (e.g., Events of pressing/releasing of keys) to the log file.
None disables keyboard tracing.

XDMCP/ACCESS debug trace into 'c:\xservert.dat' file

If checked, this check box enables writing out any special debugging information into the c:\xservert.dat trace file.
Be careful when using this option because of significant decreasing the XServer's performance and a large size of the trace file.

Trace Fonts Requests

If this check box is checked, then all font requests from X clients (with resolve messages) will be stored in the xserver.out file. This option is useful for analysis of the font accessibility and resolving font problems by XServer.

The Network trace Box

When the Network trace check box is selected, it enables network tracing between XServer and remote X clients.

Network trace level name

A value in this field that you can choose from the list box denotes a tracing level for collecting network trace information for your X-session to the log file.

Trace file name

In this entry field, you can specify a name for a log file to store network trace data.

Number of lines for trace buffer

In this entry field, you can type in a length for the allocated memory (in number of lines) to flush it to the trace file.
The value of 0 means a "very large" buffer (as much as your system allows).
Caution: when a system crash happens, the data in the allocated memory is lost.
