Everything was OK till the day KDE's sound indicator (in system tray) disappeared randomly; And after a while permanently! I don't have sound indicator in system tray now; It's gone! Somehow weird but due to this issue, I cannot turn off my computer. Neither restart nor log out. There is absolutely no reaction when I click on them.
Googled the problem a little and got this command:
Code: Select all
sudo shutdown -h now
Which fortunately still works
IN CASE MAYBE HELPS:
- I didn't have such problem before.
- sudo shutdown -h now only and only works with its h. Without h, its useless.
- After sound indicator, a little program (I forgot its name, but it was for clipboard) started behave the same. Now it's gone too.
- I also upgraded KDE 4.08 to 4.11.1 (I had the thought it might be a bug or something).
- OS: Mint KDE 13 (MAYA)
Now, what should I do about it?
