Comment 6 for bug 510001

I have to withdraw my previous comment.

The truth is that I have two machines theoretically with the same configuration (except the hard drives are different). Both are the same acer ferrari 4005 WLMi model. In one of them the color depth degradation still appears while the other one suffers from Bug #524860 related to gnome-keyring but color depth changes after suspend/resume does not appear.

I did the following experiment: I switched on both machines when booted up I logged in, suspended and resumed. After these I coppied the file from /var/log/Xorg.0.log to

Xorg.0.log_homepc (refers to homepc suffering from color depth changes after resume) and
Xorg.0.log_hardnut (refers to the other laptop without any issue after resume)

Please, find the difference between the two files here below. (It seems that the two radeon x700 cards are a bit different)
