Xfce4 applications lost its connection to display

Question

Hi, I was using arch with xfce4 with no problem at  all... but today xfce4 seems to have very strange problems...
As usual I logged in and give the startx command, well this time xfce starts loading but after this i've only a black screen with mouse pointer....
I thought it was an X server problem, but blackbox works fine... Then I discovered that xfce is running but not showing anything,  if i tape ALT+F2 xfrun4 starts and I can start any applications I want (as the browser I'm using now) including xfce4 application like xfce4-panel or xfce4-session , that didn't start before as usual...
So the problem seems to be that the DE can't initialize it's services, but it sounds strange 'cause before I never had any problems, and I don't remember if I upgraded somethingh during laste working session...
Xorg log in /var/log  seems to be useless, so I post my ~/.xsession-errors:
bash: no job control in this shell

Answer 1

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
