no icons after updates installed
i have an old ibm thinhcentre (s50)drivers on windows system i upgraded from ver13.4 to 13.10 as the grahics drivers for linux were no longer available for linux 13.4(ubuntu) it worked fine with my icons on the left ie home settings dash etc. i installed the latest updates this morning and all i get after restart is my wallpaper(no task bar on the left. i managed to lnstall chrome which i can load from the terminal (ctl+t then google-chrome-stable)in chrome on facebook my games now work fine so assume the graphics driver has made a difference.
