[Bug 876762] Re: KDE crashes at login with desktop effects enabled
** Attachment added: "GDB crash report of X"
https://bugs.launchpad.net/bugs/876762/+attachment/2554839/+files/X_Log.txt
** Description changed:
I have a HP DV6 6121tx laptop, with Intel Core i7 sandybridge and a
discrete GPU (Ati 6770m) and an Intel GPU.
Whenever I login to Kubutu with desktop effects enabled, X crashes at
the KDE splash screen and drops back to the login screen (kdm). Any
subsequent logins work since KDE automatically disabled desktop effects
after a crash.
However, if I login with effects disabled and enable then _after_ logging in then everything works fine until I logout.
I've also tested compiz, and it works without any problems.
+ All packages are of latest version.
Here's some more info:
