Black Screen after Suspsend on HP Pavilion g4

Postby leehach on Sat Jun 28, 2014 2:36 am

I've found several posts related to this, but none have been helpful yet. I have an HP Pavilion g4 laptop with AMD A6-4400M processor and AMD/ATI Trinity Radeon HD 7520G graphics card. I have been running Maya on this laptop for over a year, and suspend has worked normally. I just installed Quiana, and when I suspend the computer, on resume the screen is black.

Some additional information:

Several posts address the issue of the computer not actually resuming properly and have you check the UUID of the swap space. I have confirmed that this is not the problem. If I play a music file before suspending, when the laptop resumes the music file resumes playing. I can also use Alt+F4 to exit the music player, and other keyboard combinations to shut down or restart the computer. So resume is working, and as far as I can tell this is just an issue of the display not turning on.

Hitting the brightness controls does not change anything.

Using Ctrl+Alt+F1 to open a TTY session does nothing, nor does following that with Ctrl+Alt+F8 to restore the graphical session.

I have retained Maya on the hard drive, and when I boot Maya, I can suspend and resume normally. When I boot Quiana, the screen does not wake up. I have also tested this with the Live USB, and Maya and Quiana both show the same behavior. Maya works as expected, Quiana does not.

Following this post, I have tried several quirks, including --quirk-dpms-on, --quirk-radeon-off, --quirk-s3-bios, --quirk-vbe-post, and --quirk-vbestate-restore. None of them seemed to fix the problem.

Any help in diagnosing and fixing this problem would be appreciated.

Found this bug report: Ubuntu 14.04 blank screen after wakeup from sleep. This appears to be the same problem I am having, and `nomodeset` works to allow suspend and resume. However when the desktop starts I get the notification:

Running in software rendering mode

Cinnamon is currently running without video hardware acceleration and, as a result, you may observe much higher than normal CPU usage.

There could be a problem with your drivers or some other issue. For the best experience, it is recommeded that you only use this mode for troubleshooting purposes.


So, it does not seem ideal to leave it this way, even though resume is working. Does this help diagnose the problem and suggest fixes?

I installed proprietary drivers for my video card (fglrx) and that seems to have fixed the problem.
