Netsurf and erratic keyboard/mouse interaction

[marcelru]

Hi everybody,

First of all: all the best for the new year!

Two days ago I started with the connection of a mouse and keyboard to my TV. ( see http://forum.samygo.tv/viewtopic.php?f= ... =30#p10611). This morning, after playing around with different modules and device special file insertion places I got it working (thanks again, arris69).

My hardware:

UE40B7020WW (CI, no +)
logitech M505 mouse
logitech K750 keyboard
(both connected to the tv through a single unifying receiver)
sitecom 4-port micro hub

(and yes, I like shiny black hardware )

The software is just the mouse and keyboard package (v 0.01), with a modified startup script.
FW version 2008-something, from may 2009, T-CHU7DEUC, I never bothered to upgrade to the last SamyGO compatible version, after all, if it ain't broke, don't fix it.
Now when I start NetSurf, the mouse works fine until I hit the keyboard: typically, I move the mouse from the center of the screen to the text bar at the top, start typing a URL and after that the mouse and keyboard seem to have a fight as to who gets cursor control first. The mouse cursor blinks at a high rate and ultimately moves to where I send it, at a very low pace. When I leave everything alone, after some seconds, I can use the keyboard again, but as soon as I touch the mouse, its motion becomes erratic and slow again. This process is repeatable, indefinitely (well, at least for a quarter of an hour). I played around with mousepolling speed options for usbhid.ko, but that didn't do much. I couldn't find any information on this in the forum or the wiki, so I turn to you all.

Does anyone in this forum have the same experience?

Is the erratic movement caused by the mouse driving modules (usbhid.ko and evdev.ko) or by NetSurf? So far I haven't tested any other SamyGO "games" requiring a mouse.

Or is it a hardware problem (an old wired USB mouse shows the same behaviour, so I personally don't think so).

Thanks for any input,

marcelru

..

np, but can you pls. provide exact commands and modules (from where you got them) for your setup
for the lag of mouse i have no idea, sry.

thnx

I think other users have reported a similar problem
http://forum.samygo.tv/viewtopic.php?f= ... t=10#p4533

I recall earlier versions of Netsurf were worse, but there was a recommended "Options" setting for

fb_mouse_delay:50

that seemed to help.

Hi all,

@jw1001:

I have the latest SamyGO version of Netsurf, with fb_mouse_delay set to 50: doesn't help I'm afraid.

@arris69

The modules are the ones by geo650, taken from:

SamyGO Mouse and Keyboard Modules v0.01.zip

I made this script to install them:

Code: Select all

#!/bin/sh
#
#
# ad-hoc script to start mouse and keyboard kernel modules 
#
# mostly taken from examples by geo650 and arris69.
# 


echo mouse_and_keyboard.sh $1

MODULE_ROOT=/dtv/usb/sda1/.module/mouse_keyb
DEV_ROOT=/dtv

case "$1" in

start)

# insert kernel modules

insmod $MODULE_ROOT/evdev.ko
insmod $MODULE_ROOT/usbhid.ko
# make device special files for mouse (not sure if all are needed, but this 
# works)

if [ ! -d $DEV_ROOT/input ] ; then
        mkdir -p $DEV_ROOT/input -m 777

esac  

Like I said, things are working, but for the keyboard/mouse interaction.

grtz,

I don't know what difference it would make, but the original MouseandKeyboard.sh file supplied creates 32 device nodes

Code: Select all

# Generate input device nodes at /dtv
i=0
while [ $i -le 31 ]
do
	mknod /dtv/event$i c 13 $(($i + 64))
	i=$(( i + 1 )) 
done

hi,

made some mouse tests (on UE..B7020):
modules from different extensions packs all ok.

netsurf just needs device file /dtv/event0 (i am not sure about wireless combi devices, mouse and keyboard, so in this case maybe /dtv/event1 is used too)

Code: Select all

svn log /home/Video-HD/samygo/SamyGO-Extensions/InitScripts/trunk/init.d/01_05_hiddev.init

r1080 | arris69 | 2011-01-10 16:31:59 +0100 (Mon, 10. J?n 2011) | 1 line

NetSurf needs /dtv/event. .

the wireless mouse has a bit strange movement and reaction time but it's usable (wheel don't works, test distance ~3m) .
wired usb mouse has better movement and reaction, wheel worked too.

so it's maybe something in the protokoll or this wireless sh... just works up to 1 meter

Hi arris69,

I also think that so many event devices aren't necessary.
Anyway, I just had a go again and I think it has to do with interaction between keyboard and mouse in the software. As soon as I hit enter e.g., in google search, (which doesn't work to start a search BTW) the mouse slows down to almost no speed at all.

So probably it is software, not the hardware. On a "normal" linux box the combo just works the way it should. In a different thread (specific for netsurf) I read similar complaints about keyboard functionality. Anyway, I will try and install some other apps that require keyboard and mouse, just to see if it is NetSurf or something else.

thanks for your efforts,

marcelr
