view story

http://askubuntu.com – I was running Google Chrome just fine but I noticed that was too many chrome process running, one of them consuming with high memory usage, so I decided to terminate that unique chrome process. Since I did that, I having chrome black screen for all visited pages. Have already tried to remove chrome from synaptic and installed it again but the black screen persists. Also, my google chrome icon are not right, displaying a kind of document icon instead. Any tip?? (HowTos)
