Binary package hint: gnome-panel
I have a three screen set-up spanned over 2 nvidia 9600GTs via Xinerama, with a Gnome panel at the bottom of each of these three screens and one at the top of the centre screen. There is a window list on each of the bottom Gnome panels for managing windows on each screen separately.
Since upgrading from 9.04 to 9.10 applications listed on the window lists become unresponsive and do not react to any amount of clicking on them, until I do a single right-click to bring up a context menu for the item in the window list, it then allows me to left-click on it to bring it to the top of my work space. I can't find a pattern to it, sometimes it will let me switch between windows fine and most of the time I have to right-click them first. I can generally click on each window in each of my three screens and some will react and some will not, and from what I can see, certain windows reacting will then allow other windows that were previously not reacting, to react without right-clicking.
I'm unsure if this is related, but I had to disable glx in my xorg.conf file to get my three screen set-up working again after upgrading to 9.10. I'm using gnome-panel version 1:2.28.0-0ubuntu6
I'm unsure what log files to attach that would be relevant, so if anyone needs one, let me know.
not confirming the issue there, setting to low it's a one user thing
