Description Lubos Kocman 2010-07-26 13:41:35 UTC 
Description of problem:

I found that mouse coordinates become somehow garbled after changing resolution from lower to higher.

I was able to reproduce this issue on Win7 guest with 2 displays. I'll try to find out how much system/display specific the issue is.

Version-Release number of selected component (if applicable):

spice-server-0.4.2-14.el6.x86_64
spice-client-0.4.2-15.el6.x86_64
qemu-kvm-0.12.1.2-2.96.el6.x86_64

Guest contains software installed from RHEV-toolsSetup_2.2_46140 media



How reproducible:


Steps to Reproduce:
1. sudo /usr/libexec/qemu-kvm -vga qxl -device qxl  -m 1024 -spice port=3001,disable-ticketing -usbdevice table <win7.img>
2. /usr/libexec/spicec  --host localhost --port 3001
3. change resolution of gues from lower to higher (in my case 1024x768 -> 1440x900)

Actual results:
Both (x,y) coordinates seems to be dependent on distance from upper left corner of primary display (0,0)

I think that it behaves like (x += x, y+=y)

Expected results:

Displayed position of the cursor should be equal to the real position.


Additional info:

Display coordinates seems to be like (x += x, y+=y) from upper left corner of the primary display.

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

Hi Lubos,

Please retry with the following in mind:
1. Do not use -usbdevice tablet when running with multi-monitor spice.
2. Use spice-vmc device (-device virtio-serial -device spicevmc,nr=0)
3. Install qxl driver on guest
4. Install spice-vmc driver on guest
5. Install appropriate vdagent and vdservice (they are not the same as in
   RHEV-2.2, adjusting to the new spicevmc device)
6. Make sure vdservice and vdagent are running
   - start -> run -> cmd  +   net start vdservice  (or check the logs)


Following the above, with a Win XP guest, I could not reproduce the bug.

Ping me on IRC if you need any help.

Thanks.
