.TH XQVSS 1 "Release 5" "X Version 11"
|
|
.SH NAME
|
|
Xqvss - QVSS server for the X Window System
|
|
.SH DESCRIPTION
|
|
.PP
|
|
This driver supports the QVSS and SM displays.
|
|
.PP
|
|
The QVSS hardware in the DEC VS2 is monochrome. The usable size is 864
|
|
lines by 1024 pixels/line. (Under some versions of Ultrix, the driver
|
|
thinks the screen is 960 pixels wide; to fix this for a VR260 monitor, patch
|
|
the kernel variable qv_def_scrn to 2 and rebuild the kernel.).
|
|
.PP
|
|
The SM hardware in the DEC VaxStation is functionally identical with the QVSS
|
|
hardware, except for new cursor support and slightly different cabling.
|
|
.PP
|
|
Probably the most irritating problem with the QVSS hardware is the
|
|
cursor support, which is limited to 16x16.
|
|
As only ``and'' and ``or'' operations are available in the hardware,
|
|
the driver inverts the cursor depending upon the pixels below
|
|
the cursor.
|
|
The server displays a reasonable cursor in most (but not all)
|
|
circumstances. The SM hardware has better support \(em two planes
|
|
instead of one; exactly what X needs.
|
|
.PP
|
|
Under Ultrix-32 release 1.1 and 4.2BSD,
|
|
the window system will be slightly unreliable due
|
|
to a kernel problem.
|
|
Fixed in Ultrix32 release 1.2.
|
|
Under Ultrix-32 1.1, your best bet is to use unix domain connections
|
|
(unix:0 as host spec's) for local connections.

The server also takes all of the standard server options (See \fIXserver(1)\fP
|
|
for a complete list.)
|
|
.PP
|
|
Performance needs to be better, but the server is usable; it
|
|
uses the X11 portable monchrome framebuffer code. Look in
|
|
\fIcontrib/server/speedups/donohue.shar\fP for some ideas
|
|
which could speed up this server.
