- +o If using netscape 4.07, netscape must be configured
- properly to use the plugin for embedded X applications.
- This can be done once per system by a system
- administrator with root privileges, or once by each
- user of the system. If done by the system
- administrator, they should edit the file
- /_v_a_r/_n_e_t_s_c_a_p_e/_c_o_m_m_u_n_i_c_a_t_o_r/_m_a_i_l_c_a_p and remove the
- following lines from the bottom of the file:
- *;;
- x-mozilla-flags=prompt
- If done by the user, each user must first modify one of
- the netscape preferences, as follows:
-
- - Pull down the _P_r_e_f_e_r_e_n_c_e_s menu.
-
- - Click on the _N_a_v_i_g_a_t_o_r arrow to reveal additional
- choices, and select _A_p_p_l_i_c_a_t_i_o_n_s.
-
- - Scroll through the list of application types until
- you find the _A_l_l _t_y_p_e_s item, and click on the _E_d_i_t
- key.
-
- - Change the _H_a_n_d_l_e_d _B_y panel to select _P_l_u_g _I_n:
- _N_e_t_s_c_a_p_e _D_e_f_a_u_l_t _P_l_u_g_i_n and click the _O_K button to
- save the change.
-
- +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 Monitors which do not support EDID probing cannot be
- reliabily identified on Octane/Octane2. These are old
-

-
-
- style monitors using a parallel connector query
- capability for identification. In the
- /var/X11/Xvc/moninfo database, these are the monitors
- specifying the "QueryResponseParallel" characteristic.
- Users who may want to use these old monitors can work
- around this by editing the file /var/X11/Xvc/chantab,
- if their monitor type is present in moninfo. See man
- chantab and man moninfo 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
-
-
-
-
-
-
-
-
-
-
-
- - 3 -
-
-
-
- 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.
