Hi everyone, As a loyal Ubuntu community member, I took some of my spare time to take Ubuntu Trusty for a spin and check that all was running fine on the different hardware I am running at home and work. I did a fresh install from a live USB. Ubuntu Trusty works absolutely fine on my Dell Latitude E6400 and E6430 laptops and I am very happy with its performance. However, I can't even get to the lightdm login on my Dell E6440 (running AMD hybrid graphics). Instead, I am greeted with a low-graphics mode pop-up and can only drop back to a shell session. Trying to restart lightdm just keeps showing the same pop-up. In the last 3 day, I have kept the system up to date via a chroot on my parallel Debian install and tried again to boot Ubuntu Trusty, but still nothing. Still running my Debian unstable system with GNOME 3 for now. Any suggestions ? Thanks. Ghis
Did You try with Code: radeon.dpm=0 kernel-boot-line switch?
radeon.dpm=0
did not work, but thanks for this suggestion
Any suggestion ? Otherwise, what specific details should I provide if I were to open a bug report regarding this issue ?

See my recent thread. When it says low graphics try a get tty and use the code. I had to print it out to sort my laptop out and manually type it in.

It did not work either unfortunately.

Marked as affected and will help in confirming/triagging this one. Thanks for pointing me at those bug reports. Very much appreciated.
