-
- +o Starting with _I_r_i_x _6._5._1_4, the X server, clients and
- libraries are based on X11R6.6 from X.Org. This
- release includes many bug fixes, plus the following new
- features: support for new extensions DPMS (X Display
- Management Signaling Extension) and TOG-CUP (Colormap
- Utilization Policy and Extention); and support for RCM
- (Resource Configuration Management).
-
- +o Starting with _I_r_i_x _6._5._9, there is no longer a separate
- x_eoe product build for Trusted IRIX. The
- functionality has been merged.
-
- +o Starting with _I_r_i_x _6._5._3, the X server supports the
- AppGroup and Security extensions. Note that the
- Security extension is off by default, and is enabled by
- the command line argument -_s_e_c_u_r_i_t_y_E_x_t, which can be
- added to the file /usr/lib/X11/xdm/Xservers. In the
- current implementation, when the Security extension is
- enabled, insecure clients are allowed to access
- resources owned by other insecure clients.
-
- +o Starting with _I_r_i_x _6._5._3, the X images include a
- Netscape-compatible plugin for execution of X
- applications embedded in web pages. See _m_a_n _l_i_b_x_r_x for
- more details.
-
- +o Starting with _I_r_i_x _6._5._3, the X images include support
- for the Extended Visuals Information extension, which
- allows X clients to get visual information not
- available in the core protocol. See _m_a_n
- _X_e_v_i_Q_u_e_r_y_E_x_t_e_n_s_i_o_n for more details. Developers
- wishing to use this extension can use the optional
- interface mechanism to help ensure that applications
- fail gracefully when run on older versions of Irix 6.5.
- See the _o_p_t_i_o_n_a_l__s_y_m._h header in /usr/include for more
- details.
-
- +o Starting with _I_r_i_x _6._5._3, the X firewall proxy xfwp is
- available in the subsystem x_eoe.sw.xfwp. This
- subsystem is not installed by default. When installed
- and executed on a firewall system, this proxy can allow
- X clients running on selected hosts outside the
- firewall to communicate with selected X servers inside
- the firewall. See the _x_f_w_p(_1) man page for more
- information.
-
- +o Starting with _I_r_i_x _6._5._3, the X proxy manager can be
- configured to be invoked as a daemon on system startup
- by executing "chkconfig proxymngr on". The X proxy
-
-
-
-
-
-
-
-
-
-
-
- - 2 -
-
-
-
- manager provides access to Low-Bandwith X and firewall
- proxies. See the _p_r_o_x_y_m_n_g_r(_1) man page for more
- information.
-
- +o The default transport for local clients is a new high-
- performance shared memory transport. This transport is
- designed to avoid the security, reliability, and memory
- usage problems of the previous shared memory transport.
-
- This transport has not exhibited problems for
- applications in our testing. If it is found to cause
- problems for a particular application, it can be
- bypassed by setting the DISPLAY environment variable to
- "unix:0" (or "unix:1" for the second display, etc.).
- This will select the UNIX Domain Sockets transport,
- which was the default in previous versions of Irix.
-
- Additionally, support for the Xsgi command line option
- "-shmnumclients" has been removed. This option
- specified the number of clients which could be
- concurrently supported by the previous shared memory
- transport. The new transport dynamically allocates
- additional resources for new connections.
-
- +o Starting with _I_r_i_x _6._5, the Caps Lock and Num Lock keys
- are ignored by default for keyboard accelerators. This
- default behaviour can be changed by editing the file
- /_u_s_r/_l_i_b/_X_1_1/_x_k_b/_X?-_c_o_n_f_i_g._k_e_y_b_o_a_r_d (where the '?' is
- the display number), and commenting out the line
- starting with _I_g_n_o_r_e_L_o_c_k_M_o_d_s.
-
- +o Starting with _I_r_i_x _6._4, the default behaviour for
- logging in has been changed, such that the X server is
- grabbed until a user logs in. This means that remote
- applications will appear to hang if they attempt to
- display to a system sitting at the login prompt. This
- behaviour can be altered by changing the _g_r_a_b_S_e_r_v_e_r
- flag to _F_a_l_s_e in the file /_u_s_r/_l_i_b/_X_1_1/_x_d_m/_x_d_m-_c_o_n_f_i_g.
-
- +o Starting with _I_r_i_x _6._3, the default behaviour once
- logged in is to prevent applications running on another
- system from displaying on the local host. See the _x_h_o_s_t
- man page for more details, or the _d_e_s_k_t_o_p__e_o_e release
- notes.
-
- +o Starting with _I_r_i_x _6._4, the default format for 32-bit
- compiled objects is N32. Given this, the *.sw32
- subsystems have been merged into the *sw subsystems.
-
- +o _I_r_i_x _6._5 is based on the _X_1_1_R_6._3 release from The Open
- Group. The _I_r_i_x _6._2 release was based on _X_1_1_R_6.

-
-
-
- +o New R6 functionality supported in Irix 6.5 includes the
- RECORD extension, the XSYNC extension, the XC-MISC
- extension and the LBX extension.
-
- +o There are no plans to support the X Imaging Extension
- (XIE) and the MIT-KERBEROS-5 authorization scheme which
- were released with X11R6.
-
- +o _I_r_i_x _6._5 has full support for the new X Consortium
- double-buffering extension, DBE.
-
- +o _I_r_i_x _6._5 no longer supports execution of NMBX double-
- buffered applications (NMBX was an SGI-only double-
- buffering extension).
-
- +o _I_r_i_x _6._5 supports displaying MBX applications, but no
- longer supports building such applications (MBX was a
- proposed X extension that was never adopted, and that
- has been replaced by the officially supported DBE
- extension).
-
- +o The MBX extension now supports hardware double
- buffering only. It no longer uses pixmaps to
- accomodate double buffering semantics, nor does it
- support more than two buffers per window.
-
- +o Stereo-capable visuals are now supported on O2.
-
- +o Customers that compiled their own X11R5 libX11.a from
- the X11R5 sources should note that IRIX 6.5 does not
- ship the X11R5 /_u_s_r/_l_i_b/_X_1_1/_n_l_s directory with X locale
- information. Copy this directory onto your machine
- from the X11R5 release or an IRIX 5.2 or IRIX 6.0
- machine if you have programs linked with an X11R5-based
- libX11.a. Programs linked with the system supplied
- libX11.so.1 shared library will automatically use the
- new X11R6 X locale information.
-
- +o The PEX extension now supports MPEX line anti-aliasing.
- PEX is compatible with Open3D 2.0 from Digital
- Equipment Corporation, and supports the immediate
- rendering and structure store subsets (but not the
- workstation subset) of the X Consortium PEX 5.1
- protocol. MPEX is a collection of PEX extensions
- defined by Digital for use with their PHIGS and PEX
- products.
-
- +o The server now supports motion history buffers for X
- Input Extension devices. This support is disabled by
- default. See the _i_n_p_u_t(_7) man page for information
- about enabling this support for selected devices using
-
-
-
-
-
-
-
-
-
-
-
- - 4 -
-
-
-
- the _m_o_t_i_o_n_h_i_s_t device control. See the _X_1_1 _I_n_p_u_t
- _E_x_t_e_n_s_i_o_n _L_i_b_r_a_r_y _S_p_e_c_i_f_i_c_a_t_i_o_n online book for
- information about writing clients which access these
- buffers using the X Input Extension.
-
- +o This release contains two new fonts _7_x_1_3_e_u_r_o._p_c_f._Z and
- _7_x_1_3_e_u_r_o_B._p_c_f._Z. They include the Euro Symbol, and they
- have the encoding FCD8859-15. They are part of the
- basic operating system, and they are installed by
- default.
-
- This release also contains a number of new European
- bitmap fonts for the following twelve typefaces: Dutch
- 801 Roman, Dutch 801 Italic, Dutch 801 Bold, Dutch 801
- Bold Italic, Swiss 721 Roman, Swiss 721 Italic, Swiss
- 721 Bold, Swiss 721 Bold Italic, Courier 10-Pitch
- Roman, Courier 10-Pitch Italic, Courier 10-Pitch Bold
- and Courier 10-Pitch Bold Italic, as well as outline
- fonts.
-
- Each European font contains 1016 characters. Those
- characters cover ISO8859-1 through ISO8859-10,
- ISO8859-15, and the Minimum European Subset (MES) of
- ISO10646-1 or Unicode 2.0. ISO stands for the
- International Organization for Standardization. For
- more information about MES, please use a web browser to
- open _h_t_t_p://_w_w_w._i_n_d_i_g_o._i_e/_e_g_t/_s_t_a_n_d_a_r_d_s/_m_e_s._h_t_m_l.
-
- In this release of IRIX we have added Euro Symbol to
- European fonts, and the ISO8859-15 character map.
-
- Swiss 721 fonts are installed when you install the
- subsystem _x__e_o_e._s_w._X_f_o_n_t_s. The rest of the new fonts
- are in the subsystem _x__e_o_e._s_w._X_u_n_i_c_o_d_e_f_o_n_t_s. The
- subsystem _x__e_o_e._s_w._X_f_o_n_t_s is installed by default,
- while the subsystem _x__e_o_e._s_w._X_u_n_i_c_o_d_e_f_o_n_t_s is optional.
- The new fonts are sometimes referred to as Unicode
- fonts, because they include Unicode character maps, and
- you can use Unicode codes to access characters in those
- fonts.
-
- Unicode fonts are in the CID-keyed format.
-
- +o A program called _c_i_d_x_f_o_n_t_s is used to build an X-style
- fonts directory for CID-keyed fonts. See the manual
- page for _c_i_d_x_f_o_n_t_s(_1). That program is usually run
- automatically when you install or remove CID-keyed
- fonts. If you manually make changes to CID-keyed
- fonts, you should login as root, and run that program.

-
- are provided in a subsystem called _x__e_o_e._s_w._X_o_p_t_t_y_p_e_1.
-
- +o The Network Dual-Head Software (NDS), previously
- shipped in a separate subsystem as _e_o_e._s_w._n_d_s, is now
- installed by default as part of _x__e_o_e._s_w._e_o_e. See the
- _n_d_s_d(_1) man page for information about how to use this
- software.
-
- +o A new device control option "screenchange" has been
- added. For multiple-screen display configurations,
- this option makes it possible to disable the ability to
- change the focus from one screen to another for
- particular input devices. See the _i_n_p_u_t(_7) man page
- for information about this option.
