Subject: Re: fbvnc
Dear Klaus,
Thank you very much for your answer. I have my previous (binary
downloaded with pocketworkstation) and new (compiled from source)
fbvnc programs with the -debug option and comparing their outputs and
checking the list of running programs at each stage. I have attached the
full captured session, slightly edited and commented, in case you would be
able to look through it. The important differences I noticed are the
following:
When I ran the previous version I received the messages:
True colour: max red 31 green 63 blue 31
shift red 11 green 5 blue 0
FBmouseopen: Error opening /dev/gpmdata, trying /dev/mouse
FBmouseopen: Error opening /dev/mouse
Skipping FBputcmap
14/02/2006 22:20:21 Pixel format for client 127.0.0.1:
14/02/2006 22:20:21 16 bpp, depth 16, little endian
14/02/2006 22:20:21 true colour: max r 15 g 15 b 15, shift r 12 g 7 b
1

14/02/2006 22:20:21 Using copyrect encoding for client 127.0.0.1
and kept fbvnc running, while the new version yielded
True colour: max red 31 green 63 blue 31
shift red 11 green 5 blue 0

14/02/2006 22:23:10 framebuffer updates 0, rectangles 0, bytes 0
and terminated fbvnc, leaving the screen blank (dark), although
Xfbdev, matchbox-desktop, etc., from 'familiar' seemed to continue
running. Actually, the list of running programs and their state were
identical, except for the missing fbvnc.
The main difference seem to be the FBmouseopen error messages and that
FBputcmap was skipped in the first case, while in the later case the
program seems to have quited after the 'True color message'.
As a further test I ran once again the old fbvnc. The pocketworkstation
screen appeared again as in the first run.
When I exited fbvnc the screen became blank again. However, not
completely. Actually I got some kind of console I hadn't seen before with
a message:
FBmouseopen: Error opening mouse
ofbis fatal error: FBputcmap: Put colourmap failed: Invalid argument
I believe this message is significative, as FBputcmap was skipped in the
first case.
Do you find any clue in this information?
By the way, the programs were compiled in the ipaq itself, without using
any toolkit.
On the other hand, my purpose in compiling fbvnc is to make small
modifications in order to make my external stowaway keyboard work within
the fbvnc environment. Has this been already done? Is it feasible? Can you
offer me any further advice?
Best regards,
Luis Mochan
