I'll try bisecting when I have some spare time, but it's probably going to be a few weeks.

This Notebook has 2 Graphiccars: Intel (DIS) and ATI (IGD): # lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Manhattan [Mobility Radeon HD 5400 Series] If i use the Intel-Graphiccard, everything works well, i can suspend and resume as often as i'd like. Edit: As soon as I switched (switch to ATI and back to Intel, the below problem happens on Intel-GPU too). If i use the ATI-Graphiccard i can suspend (wich takes a longer time than with the Intel one) however I can't resume. I get a blank/black screen and can't change brightness. Plus I can't switch to any tty. I've tried this instructions to find an error: https://wiki.ubuntu.com/DebuggingKernelSuspend but it dosn't seem to bring relevant informations (however, I'll add the dmesg.txt to this bugreport) PS: to switch between graphiccards, I use "vga_switcheroo" and i have "vanilla"-ubuntu, no third party software.
