I've seen this happen on my wife's laptop twice, with NVidia drivers and compositing turned on. Seems to be a NVidia bug to me. Turning off compositing and turning it back on again fixes it, or rebooting. These commands will disable and then reenable metacity compositing: gconftool -s /apps/metacity/general/compositing_manager -t bool false gconftool -s /apps/metacity/general/compositing_manager -t bool true - Jan. -- Jan Schmidt <thay...@noraisin.net> -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
