+o The 24" Sony monitor does not return a traditional
monitor ID to the system, so that by default it will
appear to look like a 20" monitor instead. Users of the
24" monitor can work around this by editing the file
/_v_a_r/_X_1_1/_X_v_c/_c_h_a_n_t_a_b and adding the line
_0._0._0: _S_o_n_y-_g_d_m-_9_0_w_1_1
This will cause the X server to override the monitor
specification on startup. See man chantab for more
details. In particular, this is necessary for the X
server to advertise the proper screen size in mm.
+o Support for newer 20" Sony monitors causes older 21"
Hitachi monitors to be reported as 20" Sony monitors
instead. This can be worked around by editing the file
/_v_a_r/_X_1_1/_X_v_c/_c_h_a_n_t_a_b and adding the line
_0._0._0: _H_i_t_a_c_h_i-_c_m_2_1_9_8_m_s_g
This will cause the X server to override the monitor
specification on startup. See man chantab for more
details.
+o If you are getting your password via NIS and the NIS
server fails, _x_l_o_c_k may crash. At that point, your
system is unlocked. A possible work-around is to keep
a copy of the password file on your local machine.
+o _x_s_t_d_c_m_a_p does not work properly, nor do the colormap
utilities in _l_i_b_X_m_u. The X server creates the standard
colormap properties by default at startup. They work
properly if not accessed through _l_i_b_X_m_u.
+o Iris GL overlay windows are not clipped properly when
obscured by a window in the overlays.
+o _l_i_b_X_t assumes that time always moves forward. If you
turn the system clock backwards, applications built
with libXt will behave improperly and often consume too
much of the system CPU. You must stop and restart
these applications.
+o If a device is already grabbed, subsequent calls to
_X_S_e_t_D_e_v_i_c_e_V_a_l_u_a_t_o_r_s will hang the application.
+o The X server does not support the large request
mechanism. Protocol requests are limited to 64K words
(262,144 bytes) in length. This applies to the core X
protocol as well as to extension protocols such as PEX.
+o The MBX extension does not support the "Copied" update
action.

+o The PEX extension does not support texture mapping.
+o PEX applications should use _P_E_X_M_a_t_c_h_R_e_n_d_e_r_i_n_g_T_a_r_g_e_t_s to
determine which visual to use.
_P_E_X_M_a_t_c_h_R_e_n_d_e_r_i_n_g_T_a_r_g_e_t_s will only return TrueColor
visuals that support depth buffering. Applications
should not assume that the visual returned to match a
PEXBufferDrawable target type is the same visual that
would be returned to match a PEXWindowDrawable or
PEXPixmapDrawable target type. The returned visuals
will be different for those graphics platforms in which
the number of hardware framebuffer planes must be
divided for use between front and back buffers when
using hardware double buffering.
+o This message is for Indy users with the 14" monitor
installed. In order to comply with EN69241 part 3, the
font used for the terminal emulator window must be at
least as large as: -*-fixed-medium-r-normal--20-140-
100-100-c-100-iso8859-1
+o The X server and local clients use shared memory as a
high performance means of communication. The shared
memory mappings cause the ppppssss((((1111)))) SZ field to overstate
the amount of memory that is actually used by these
processes. The RSS field and the ggggmmmmeeeemmmmuuuussssaaaaggggeeee((((1111)))) tool
provide a more accurate assessment of memory usage.
