I've got a bit more info. As you can also see in the 'mainline kernel install log' attachment, since this same update, I also have a graphics driver problem: no more opengl/hardware accelleration, with all of the 3 driver options (fglrx, fglrx-updates, xorg). Before I used fglrx-updates because this seemed to work the best of the 3 (not good, but better than the rest).
After install of the mainline kernel, I tried switching to the xorg option: still no opengl, but at least suspend/resume seems to work now! When I resume the computer, I get a flash of random multicolored dots and stripes, but I don't have to ctrl-alt-del anymore. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1373969 Title: Ubuntu 14.04 blank screen after wakeup from sleep on Toshiba Satellite (M50D-A-100) Status in “linux” package in Ubuntu: Confirmed Bug description: Since my last update (+-5 days ago), every time my laptop goes to sleep, I get a black screen without backlight when I open the lid, or press the power key to wake it up.
