Hi Gilles-Philippe,

All of this seems to be the fault of the graphic driver and there is no fast solution for this. If you cannot wait for the intel guys to fix this in their driver then you could back up your data and go back to fedora 20 if it worked on your laptop.

If you can't go back, then filing the bug upstream and waiting is the only thing you can do ...

Hello,

I am in deep trouble now that I have upgraded to Fedora 21. My main
production computer — a Dell Inspiron 1525 laptop — fails most of the
time to resume from RAM suspend and thus I cannot use it at school
anymore.

At the same time, this issue is accompanied by many graphical issues.
I do not know if they are linked together.

When I say "suspend from RAM", I mean closing the lid of my laptop.
When I say "resume from suspend", I mean opening that lid.
When I say "fail to resume", I mean getting a black screen with a
working cursor and responsive keyboard. The only buttons that don't
work are the brightness buttons and the Prnt Scrn buttons. Switching
to another TTY works.

I made many dmesg outputs, after boot, after a succeeding resume,
after a failed resume in another TTY. The latter does not provide me
anything meaningful, but the two first ones are filled with warnings.

I always get a warning for the i915 GPU DRM:
https://bugzilla.redhat.com/show_bug.cgi?id=962386

At boot, my kernel gets tainted because of a graphical warning:
https://bugzilla.redhat.com/show_bug.cgi?id=1177477

After a succeeding resume, I get a firmware bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1180939

And finally, the very inconvenient resume fails:
https://bugzilla.redhat.com/show_bug.cgi?id=1176645

I also get graphical glitches from time to time, but I have no idea if
they are related to the above bugs:
https://bugzilla.redhat.com/show_bug.cgi?id=1178543

I get next to no responses in Bugzilla after weeks. The Google+
community points me to my own Bugzilla filings. The IRC tells me to
use Google. How can I solve this fast?

Here's my setup:
Fedora 21 Workstation
Processor: Intel® Pentium(R) Dual CPU T2390 @ 1.86GHz × 2
OS Type: 64-bit
Graphics: Intel® 965GM
GNOME: Version 3.14.2

I installed the following software since installation:
Age of Empires (WINE)
Blender
California
cmus
Dropbox
GIMP
Google Chrome
LibreOffice 4.3
Pidgin
Simple Scan
Skype
Steam
Tweak Tool
vim
Wine
World of Goo (Steam)

I am willing to give any additional information that can accelerate
the solution-finding.

Please help me, thank you.
