Public bug reported:
CID: 201107-8258 Lenovo ThinkPad Edge E525
With the open-source radeon driver, there is no display after resume from
suspend.
But the system still working, I could open a terminal and reboot the laptop
with sudo reboot.
There is no such problem with proprietary drivers,
but the brightness control issue (bug 1243508) will make both of these two bugs
become a blocker
