Recently installed Stephenson's rocket in a Lenovo t420.
During installation, it didn't recognise the graphics card, an intel hd graphics 3000, and recommended to use aticonfig --initial.

Didn't solve the problem, when lightdm is launched and steam in big picture mode, the screen is flashing in black continuously. That doesn't happens if I launch gdm3, in that case the screen is working correctly, so I supose theres some issue with lightdm conf.

Hi there,
Recently installed Stephenson's rocket in a Lenovo t420. During installation, it didn't recognise the graphics card, an intel hd graphics 3000, and recommended to use aticonfig --initial.
That didn't work, so I tried installing debian recommended packages for t420: https://wiki.debian.org/InstallingDebianOn/Thinkpad/T420/jessie
