No login screen: Failed to initialize glamor at ScreenInit() time.

[0x656b694d]

Hello,

The login screen disappeared on my Asus eeePc. Interestingly, with the same 15.04 + xorg-edgers I have everything working fine on my desktop computer.

The Xorg.0.log on the problematic machine:

[    36.205] (II) Loading /usr/lib/xorg/modules/libfb.so

Fatal server error:

Any ideas? I tried to purge xorg-edgers, but it didn't help.

Thanks in advance!

I've reinstalled from daily iso and the issue is gone.
