Comment 25 for bug 326344

The workaround that worked for me with kubuntu was to login with failsafe and install e16. Then exit failsafe and login with e16-kde. This then allowed me to start systemsettings>Desktop>Advanced and uncheck "Enable direct rendering". Then apply and log out. Then log back into kde with full effects.

I actually tried a bunch of things to get this working, but I believe what I posted above is what ended up working. I'm also sure there's a better way to do this, but I just needed any functional desktop at first to check email and stuff and randomly picked e16. Was just luck that it had the option of e16-kde for logging in. I'll try to check back here later and see if there's any questions about this.
