Public bug reported:
Problem description : if X forwarding from a server (solaris 10 in my case) and
if I click using right mouse button into a forwarded window to invoke some menu
typically, the whole GUI appears frozen - but it is not. Windows and gnome is
further refreshed and working, but mouse and keyboard are dead until the
X-forwarded application is killed from the console (CTRL+ALT+F1), like killall
ssh.
This problem seems the whole ubuntu 10.04 oriented - tested also on install CD
10.04, install CD 10.04.1, Kubuntu install CD 10.04.1.
Testing :
* Tested on two independent hw platworms - one with intel GPU and one with
GeForce.
* No difference if ssh -X, or telnet is used to forward X.
* As mentioned above, no difference which desktop environment is used
(gnome,KDE).
* Situation described above works without any problems on ubuntu 8.10
Logs written right after the X forwarded app is killed :
(none interesting before)
