Hello everybody I'm experiencing this bug too , I'm running Kubuntu 14.04 lts 64bit and using fglrx-updates (Radeon HD 7790) I don't know if this applies to other setups... distros... different window-managers etc ... This is the only scenario in which I could test and have this problem.
The steps I've taken to reproduce this behaviour are the following: 1 - Install fglrx-updates drivers 2 - Wait for the display to be switched off by the power-manager 3 - After the screen has fully switched off and entered stand-by mode, trying to move the mouse or hitting any of the keys on your keyboard simply does not wake up the screen. Your display is permanently stuck in sleep mode and you have to reboot your computer. There's "just" something wrong with the computer telling the screen to wake up because while the display is off, the system is still running I guess as I managed to avoid hard-resetting my computer by using the terminal and issuing a shutdown command (going by memory, since the display is OFF). I haven't tested the workarounds suggested above but I'll keep this post updated as soon as I try. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/958279 Title: FGLRX DPMS support totally broken, fails to wake up the monitor after putting it to sleep.
