I installed Ubuntu 14.04 LTS on on an Acer Aspire 5715Z (Intel T2390 with 2Gb of RAM). I am experiencing a weird problem:
Every time I open Google and visit the Extensions Gallery, the whole Unity Desktop crashes. Restarting the LightDM service doesnt help and I have to reboot the machine.
I tried to delete the profile directory under $HOME/.local/google-chrome/ - same...
Another weird problem - every time I enter the desktop I have to unlock the Login Keyring, although I have changed the password to a blank password....
Any pointer would be helpful.
