[Qemu-devel] Guest not responding to my PS/2 mouse

[Qemu-devel] Guest not responding to my PS/2 mouse

[Gervase Lam]

Being a bit of a newbie to qemu, I was wondering if I could get some
help with my PS/2 mouse.  When the QEMU window runs the guest system,
the guest GUI responds to the keyboard but not my PS/2 mouse.  It works
in the Gnome windows manager that is running QEMU.

Could somebody tell me where I should start looking to sort out my
mouse?  I used the following command line to run a disk image, which
successfully starts up Grub and then the Mandrake 10.1 Linux GUI:

~/develop/qemu/svn/x86_64-softmmu/qemu-system-x86_64 -cpu pentium3 -hda
working.img -boot c -snapshot -m 512 -localtime -L
~/develop/qemu/svn/pc-bios/ -no-kqemu

Thanks,
Gervase.

Have you tried clicking on the window?

Your command line looks a little contradictory: A Pentium 3 is not an  
x86_64 CPU. If you really want to emulate a Pentium 3 you can use the  
"qemu" executable instead (i386-softmmu). Unlikely related to the  
mouse though.

The window banner initially displays "QEMU".  I then click on the
window.  The banner then changes to "QEMU - Press Ctrl-Alt to exit
grab".  I move the mouse around.  There is no response.

Another unrelated problem is that when I run without kqemu, I
successfully get the Mandrake login GUI.  But when I run it with kqemu
enabled, I don't get the GUI.  I just get the terminal Linux login
prompt with errors like "vgetty FATAL: yS4  cannot get TIO".  I get the
same if I use the -std-vga option.  But this is for the moment a minor
problem compared to the mouse problem.

Thanks,
Gervase.

Hmmm.  When I boot the Windows 98 OS instead that is in my disk image,
the mouse works but it is not very "smooth".

Things like, the mouse cursor jumps from the bottom to the top of the
screen when I move the mouse up.  Then moving it left-to-right and
right-to-left, the mouse jumps about 50 pixels left-to-right and
right-to-left.  And the cursor gets stuck in these two horizontal
positions.  Oh yeah, the cursor is also stuck at the top of the screen
at this point.

So, it looks like I'll need to look at the mouse code in qemu.  And I
know that there was a lot of minor fiddling around in that area a few
months ago...

Thanks,
Gervase.

This has fixed the PS/2 mouse when I booted my disk image into Mandrake
10.1.  Thank you!

It also mostly fixed PS/2 mouse functionality when I booted the image
into Windows 98.  However, I have to move the mouse very slowly, even
though the mouse cursor does not move very far in the process.  If I
move it suddenly, the mouse cursor just jumps from one edge of the
screen to another.  Even lifting up my ball based mouse to readjust the
position of my mouse physically causes this problem.

May be this is just due to the mouse acceleration detection.  However,
what I find weirder is that when the cursor jumps around, it sometimes
decides to automatically click the mouse button for me causing menus to
appear when I don't expect them to...

Thanks,
Gervase.
