[Bug 987496] Re: Unity is working incorrectly after returning from standby mode


** Description changed:

  Ubuntu desktop is working incorrectly after returning from standby mode or editing Nvidia X server settings. Unity is slow, unresponsive and is working incorrectly. The launcher is not working and top bar is invisible and mirroring one row of background.
  I have attached some screenshots of the problem. While I took the screenshot sound of screenshot was played immediately but the screen flashed few seconds later very slowly. By logging out and logging in again the problem disappears. Byt if I change account and log again in to my account the problem appears again. Changing display drivers will affect to this problem.This problem was in earlier ubuntu versions but it is worse on 12.04. In earlier versions of ubuntu the display was normalized after changing desktop. I had this problem on ubuntu 11.10 in gnome-shell 3.2 but it disappeared after changing display drivers. Ubuntu is 12.04 LTS Beta 2 Precise Pangolin. Display driver is NVidia 295.40.
  To reproduce: Use a NVidia Graphics card (if possible Nvidia GF7600GS)
  Install the latest Nvidia driver from Ubuntu with the Additional drivers
  tool. Set the launcher to hide itself automatically. Put the computer to
  standby mode and wake it. Try also to edit the Display settings with
  NVidia X server settings. Apply the settings after editing for exapmle
  the display refresh rate. After waking the computer or applying the
  settings try to reveal launcher or do anything else with ubuntu.
+ The system unresponsiveness seems to be a older issue which is reported
