Well it seems that after all this was not linked to the new kernel, rather to Gnome and/or GTK. After an update, everything is back to normal. The following packages were upgraded:
gtk2-engines-pixbuf 2.8.18-0ubuntu1 -> 2.8.18-0ubuntu2 libgtk2.0-0 2.8.18-0ubuntu1 -> 2.8.18-0ubuntu2 libgtk2.0-bin 2.8.18-0ubuntu1 -> 2.8.18-0ubuntu2 libgtk2.0-common 2.8.18-0ubuntu1 -> 2.8.18-0ubuntu2 libgtk2.0-doc 2.8.18-0ubuntu1 -> 2.8.18-0ubuntu2 -- Regressions with upgrade from kernel 2.6.15-23 to 2.6.15-25 https://launchpad.net/bugs/50599 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
