** 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.
