Does anyone have experience running rio under qemu?  My cursor is  
hooped - I can see its left-most pixels running on the edge of my  
screen, and bring up rio menus there, but I can't get it to the  
middle of my window.

Hints?

my cursor under qemu is weird too. when i first try to use it after
booting, it can never address the whole screen, only one piece of it.
and it's not the same piece; sometimes it's a corner, sometimes the
middle.
i haven't looked at any code, but moving the cursor faster, trying to
address the whole screen, gives me good results sometimes.

Iru, I have experienced this problem. What you need to do is click
your host's cursor on top of the Plan 9 cursor, in order to allow it
to reach the entire screen.

You are likely running into a mouse emulation bug where the
cursor can't go past an invisible wall.  A work around is to
slide the cursor in the waaay over in the opposite direction.
AFAIK this is fixed in a later version of qemu.  or atleast
it is fixed in 0.8.2 on freebsd.

Ack - sounds like a bad interaction with synergy, which I use to  
share my mouse and keyboard across from my mac.
And sure enough - I just plugged in a mouse to that machine, and it  
works fine.  I'll ask the Qemu folks how to make it work with Synergy.

Thanks,
     Paul

I've never seen that problem using Qemu in the same machine where I run
the x server. But I've had the problems you describe through Tightvnc.

Yeah the invible wall bug is really annoying, and for the linux version of
0.8.2 it's still there. The best way to get rid of them, I found, is to go
out of full screen and back into it (or vice versa), and somehow the walls
disappear. On another note that I've been wondering is if it'd be possible
to remap my keyboard so that the ` key will act as mouse button 1, etc. I've
tried doing this in linux (since mice click very loud) via xmodmap without
any success. Just wondering if it'll be possible under Rio.

Hey, do you mind trying what I suggested? Leave cursor-grab mode, and
the move the X cursor right on top of the Plan 9 cursor and click. Now
there shouldn't be any invisible walls.
