No display after resume from S3 with AMD graphic cards and open-source driver on 12.04.5

[Po-Hsu Lin]

Suspend / resume works fine, just no display after resume from suspend

These systems were certified with proprietary drivers,
but they're not available on 12.04.5, see bug 1352843

AMD Radeon HD 7340 [1002:9808] 201206-11156
AMD Radeon HD 7560D [1002:9904] 201206-11409
AMD Radeon HD 7540D [1002:9991] 201206-11396

Combined with the proprietary driver issue, it will make both of these two bugs become blockers.

I prefer to unblock bug 1355041 first, that bug should be easy to fix.

Now bug 1355041 is fixed, can this bug be set as non-blocker?

Hello Anthony,
Yes I think we could set this one as non-blocker.
Thanks!
