Description David Craven 2016-07-02 17:29:11 UTC 
Description of problem:
When connecting to a qemu vm through spice the screen resolution isn't sent to the spice-vdagent deamon when the window is resized. Clipboard works as expected.

Version-Release number of selected component (if applicable):
Qemu 2.6
Virt-viewer 4.0
spice-vdagent 0.17.0

How reproducible:


Steps to Reproduce:
1.
2.
3.

Actual results:
spice-vdagent[575]: 0x1e07dc0 connected to /var/run/spice-vdagentd/spice-vdagent-sock
spice-vdagent[575]: Selection window: 33554433
spice-vdagent[575]: Screen 0 1024x768+0+0
spice-vdagent[575]: 0x1e07dc0 sent guest xorg resolution, arg1: 1024, arg2: 768, size 16
spice-vdagent[575]: net_wm_name: "Xfwm4", has icons: 1
spice-vdagent[575]: 0x1e07dc0 received version, arg1: 0, arg2: 0, size 7
spice-vdagent[575]: 0x1e07dc0 received client disconnected, arg1: 0, arg2: 0, size 0

Expected results:
I expect spice-vdagent to produce a log entry when window is resized.

Additional info:
qemu-flags:
export QEMU_FLAGS="-vga qxl \
-spice port=5930,disable-ticketing \
-device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5 \
-chardev spicevmc,name=vdagent,id=vdagent \

Maybe this is related:

Hi, It is not a bug, in the past agent handled resizing. But now it is handled by qxl (drm kernel driver), however it needs some support in window manager - currently implemented in GNOME (mutter). I don't know about support in other desktop environments.

This one is a well-known old GTK bug. See bug 1488249.
