Public bug reported:
Binary package hint: ssvnc
Description: Ubuntu 10.10
Release: 10.10
After opening a VNC session, FullScreen status can be toggled either via the F8
popup menu, or through a dedicated F9 key binding. Using the F8 popup menu
seems to work fine. Using F9 repeatedly tends to hang the X server after a few
on/off toggles. In Lucid I could toggle a couple dozen times in quick
succession without issues.
In order to reproduce the hang it seems to be necessary for the VNC
session in question to be larger than the current display. For example I
am running on a 1600x900 monitor and connecting to a 1600x1200 VNC
session (started with "vnc4server -geometry 1600x1200").
I'm filing this initially against ssvnc because that is the only pre-
built application against which I can reproduce it. However I suspect
the actual problem might be closer to the X server code. The hang does
not seem to be reproducible when visual effects are turned on. Also I
have a hacked copy of "vnc4viewer" in which the FullScreen toggle is
bound to F12, and a similar hang seems to be reproducible with that
viewer.
Reproduced on a Dell Inspiron 1545 laptop with Intel 4500MHD graphics.
