In the day or so I have had problems with the Netbook remix being slow to respond and not redrawing the desktop when closing or minimising applications. I experiencing several system pauses, where the applications are becoming unresponsive for 5-10 seconds. These pauses were after the netbook remix desktop stopped redrawing itself. I accessed the gnome menu using Alt-F1 (to run gedit as I could not get to the desktop) and the system hung for about 20 seconds. The panel died and after about 10 seconds reappeared and started to redraw itself. After a few more seconds the system was back to normal performance and the netbook remix desktop draws itself and general performance is back to normal. I have experienced issues with windows not always opening fully maximised, but this is a relatively rare occurrence. I am running Ubuntu remix 9.10 with the latest updates on an Eee PC 1000. The only 3rd party sources added are for chromium, which was not running at the time. I was running Firefox, a java webstart application called Hudson, a terminal and gedit (eventually). None of the applications were affected apart from the slowness of the system. In the syslog for this morning I found the following related to gnome-sesson / netbook-launche processes.
