                      3: .SH NAME
                      4: Xqvss - X window system QVSS implementation notes
                      5: .SH DESCRIPTION
                      6: .PP
                      7: The QVSS hardware in the DEC VS2 is monochrome.
                      8: The usable size is 864 lines by 1024 pixels/line.
                      9: (Under Utrix 1.1 the driver thinks the screen is 960
                     10: pixels wide; to fix this for a VR260 monitor, patch
                     11: the kernel variable qv_def_scrn to 2.).
                     12: .PP
                     13: Probably the most irritating problem with the QVSS hardware is the
                     14: cursor support, which is limited to 16x16.
                     15: As only ``and'' and ``or'' operations are available in the hardware,
                     16: the driver inverts the cursor depending upon the pixels below
                     17: the cursor.
                     18: The server displays a reasonable cursor in most (but not all)
                     19: circumstances.
                     20: .PP
                     21: Under Ultrix-32 release 1.1 and 4.2BSD,
                     22: the window system will be slightly unreliable due
                     23: to a kernel problem.
                     24: Fixed in Ultrix32 release 1.2.
                     25: Under Ultrix-32 1.1, your best bet is to use unix domain connections
                     26: (unix:0 as host spec's) for local connections.

                     33: The server also takes all of the standard server options (See X(8)

                     35: .PP
                     36: Performance needs to be better, but the server is usable; it
                     37: uses the X11 portable monchrome framebuffer code.
