@anthony
刚试过了 ubuntu ，也存在此问题

这个 bug 跟 bug 1362086 是不是同样的问题？

@anthony
#1362086 狂闪，不能用
这个bug是不闪动，只有launcher和桌面，但launcher和桌面图标都点不了，

ubuntu beta1 安装后，图片见附件。

安装 ubuntu daily build，然后 apt-get update && apt-get dist-upgrade，如果问题还重现，把 log 发上来。

machine : laptop
(1) HP-Pavilion-Sleekbook-15-PC

(2) msi GE60 2OC\2OD\2OE REV:1.0
cpu：Intel core i5-4200M CPU @ 2.50GHz ×4
graphic　Intel Haswell Mobile
                     IntelR（R）HD Graphic 4600
                     Intel Corporation 4th Core Processor Integrated Graphics Controller(rev06)(prog-if 00[VGA controller])

I try different parameters in grub menu: nosmp, noapic, acpi=off, it takes no effect.
I switch to console with Ctrl+Alt+F1, the problem appears after login. The attachment is error info on the console. It seems that the problem is related with CPU?

@anthony
I install the latest iso , and could not get log file, because the terminal(ctrl+alt+f1) could not input ,
please look at the picure in attachment!

and I install ubuntu iso (the latest), it could not installed.

shijing, could you please follow the steps in comment #9 so there will be more information to trace the problem? Thanks.

@anthony , for a couple of days , this phenomenon does not appear
