Bug#382264: vncserver doesn't allow specification of -dpi option

[Chris Moore]

Package: vncserver
Version: 3.3.7-12
Severity: normal
Tags: patch

When I use vncserver and connect from a remote machine, everything is
much smaller than when I work directly on the desktop.  This seems to
be because the dpi setting is different.

I would like to be able to specify a value for the "-dpi" flag either
in my .vncrc file, or as a flag to the vncserver command, but that's
not possible.

I made some changes to the realvncserver script to allow both of these:

------------------------------------------------------------------------

I can now add "$dpi = "100";" to my ~/.vncrc and have the VNC session
use bigger fonts.

Notice that the man page for Xrealvnc doesn't mention the -dpi flag,
but it does definitely have the desired effect, and Xrealvnc's -help
flag does document it:

$ Xrealvnc -help 2>&1 | grep dpi
-dpi int               screen resolution in dots per inch

I can modify the manual pages and sample .vncrc file appropriately if
my changes would be used, and if nobody else wants to do it.
