- I hold the button down and shift the trackpoint up and down.
xterm shows no scrolling movement at all.
- Log in /var/log/xwin/XWin.0.log during this:
a) still comes at the moment when I shift the trackpoint up and down,
b) but it doesn't look regular any more:
There are MUCH more lines
winMouseButtonsSendEvent: iEventType: 4, iButton: 5, nEvents 2
winMouseButtonsSendEvent: iEventType: 5, iButton: 5, nEvents 2
and only a few lines
winWindowProc - WM_MOUSEWHEEL
in between.
Looks like this:
[ 473.447] winMouseButtonsSendEvent: iEventType: 5, iButton: 5, nEvents 2
[ 473.447] winMouseButtonsSendEvent: iEventType: 4, iButton: 5, nEvents 2
This looks a bit like the trackpoint is sending us a WM_MOUSEWHEEL for a much
larger mouse movement (which we need to break down into multiple button 5
press/releases)
Maybe this is an interesting section, it contains an EQ overflowing:
[ 350.612] [mi] EQ overflowing. The server is probably stuck in an
infinite loop.
This means that the events are being generated faster than the server can
process them.
- I release the button. At the moment when I release the button, the xterm
jumps to a new position.
During this, there is absolutely no output to /var/log/xwin/XWin.0.log.
So it sounds almost like the X server is being prevented from processing X
events until the mouse button is released.
It might be interesting to try as separate test with some application which
constantly draws to it's window (like ico), if that continues drawing when the
trackpoint button is down.
Hi Jon,
here a log of my recent tests. The most interesting point is the last.
1. I modified file C:\Program Files\Synaptics\SynTP\TP4table.dat according to
new FAQ and reboot PC.
- No change of behaviour.
2. Download XWin.20120129-git-45e67e363e19a481.exe.bz2.
/bin/startxwin -- /bin/XWin.20120129-git-45e67e363e19a481.exe -logverbose 3
-clipboard -emulate3buttons 100 -nounixkill -nowinkill
-xkboptions nbsp:level3
- Doesn't start. Error message on the console is:
giving up.
/bin/startxwin: No such file or directory (errno 2): unable to connect to X
server
/bin/startxwin: No such process (errno 3): Server error.
- No output at all to file /var/log/xwin/XWin.0.log.
3. I took above startxwin command line and replace
XWin.20120129-git-45e67e363e19a481.exe by XWin.20110803-git-a493c0465e56ce0b.exe
- Immediately starts. All further tests with (old)
XWin.20110803-git-a493c0465e56ce0b.exe.
4. Today I couldn't get to the broken, jumpy behaviour by scrolling a Windows
dialog.
So this is not the breaking condition as I previously meant.
But after some time, the scrolling behaviour breaks and xterm scrolls in
jumpy way.
Sorry, I have no glue what's the condition that breaks it.
After reboot of PC it scrolls fine. Any work of 1 minute or so seems to
break smooth scrolling.
5. Then I started ico.
- While ico runs, xterm scrolls fine and smooth. As soon as I stop ico,
xterm scrolls jumpy.
- Pressing the trackpoint button has no effect to ico. It keeps painting
fine eather way.
6. I started ico with -sleep 1
ico -sleep 1
I constantly hold the trackpoint button down and scroll the xterm.
- I observe jump scrolling movements every second, one jump each second.
xterm jump scrolls exactly at the time when ico refreshes
7. close ico, start xpdf
- xpdf and xterm both have broken = jumpy scroll
8. start ico
- both xpdf and xterm both scroll fine and smooth
9. stop ico, start ico -sleep 1
- ico -sleep 1 starts, but doesn't paint anything. I do several tests.
- ico without sleep option starts fine.
close xpdf
- ico -sleep 1 starts, but doesn't paint anything. I do several tests.
- ico without sleep option starts fine.
- ico -sleep 1 starts and repaints in 1 second rhythm. Fine.
= an open xpdf seems to break ico -sleep 1, and ico -sleep 1 can be
repaired
by closing xpdf and then once running ico without options. Very weird.
2. Download XWin.20120129-git-45e67e363e19a481.exe.bz2.
/bin/startxwin -- /bin/XWin.20120129-git-45e67e363e19a481.exe
-logverbose 3 -
clipboard -
emulate3buttons 100 -nounixkill -nowinkill
-xkboptions nbsp:level3
- Doesn't start. Error message on the console is:
giving up.
/bin/startxwin: No such file or directory (errno 2): unable to connect
to X server
/bin/startxwin: No such process (errno 3): Server error.
- No output at all to file /var/log/xwin/XWin.0.log.
Possibly you need to 'chmod +x /bin/XWin.20120129-git-45e67e363e19a481.exe'

Hi Jon,
this problem still exists, it
