Today I've installed the latest updates from Deepin software center but after the reboot my machine is stuck on a black screen with no chance to do anything.
I've tried different kernels from the grub menu but it's the same. Everytime I try to boot Deepin I've got black screen where usually I had the login. I can access to the recovery mode which gives me text ui and when I launch startx black screen again.
Can someone give a hint on whats going on?

Thanks horvan for your reply, but I've already tried those. I've also tried to purge and reinstall xorg without effect. The only thing that I can do when the black screen problem appears it's to push the power button and see the Deepin logo that fades out..

Could you tell us something about your system specs. What graphic card do you use how many ram do you have is deepin installed in a vm or on it's own hard drive or partiton. Too much informations will be better then less informations nin that case.

Sure. I have dual boot with Deepin in the primary hd and win7 on the secondary hd. Amd phenom x3 cpu, 4 gb ram, ATI radeon hd 6570. Everything was fine till the last update.

may be you need to upgrade your ati driver because they have changed a bit of the compass underlayer. If you do net need to use deepin at all i recommend to wait untill the next public beta because the will use gala than.

there is a bug related to ati in ubuntus components seehere

a solution for that or at least some thoughts about are noted https://bbs.deepin.org/module it's for ubunut 11-10 but  basicly the procedure should be stell teh saem in 14.04 ak deepiin so far.

Thanks! Solved by upgrading amd catalyst driver from amd web site (using this guide:  AMD Catalyst™ Graphics Driver Installer Notes for Linux® Operating System).
It was a little tricky doing everything from command line but now everything works fine.
Thank you for your patience and your advices.
