This is my weirdest experience with Ubuntu. I had upgraded from Ubuntu 11.10 to 12.04 many weeks back. Till y'day night everything was fine. When I started my PC today morning, weird things are happening:
- "Alt + Tab" is not working at all, it appears as of only "Tab" is
taken; I am able to open terminal using "Ctrl + Alt + Tab"
(shortcut) though and move between workspaces using "Alt + Tab +
- "super" (which has
windowslogo) key is not working. Typically when I press it, it displays "start menu" kind of stuff
- It doesn't show anything on the screen except the background; Generally I used to see top bar where apps like skype, date/time, power setting etc. used to reside
- Not able to see left side app bar, which displays several icons when mouse hovers on it or "super" key is pressed
I restarted my laptop but no luck. Presently I am going to terminal and opening everything using command line, e.g. "google-chrome &" and "eclipse &", which is very annoying.
I haven't touched any of my settings in several days or install any updates, except y'day I did "sudo updatedb" just to update the
locate command. Please someone help in this regard.
