           Summary: A8-3870K graphics is broken
           Product: Drivers
           Version: 2.5
    Kernel Version: >3.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: artkun@guitarplayer.ru
        Regression: Yes


I've tested Ubuntu 12.04 and latest F17 nightly build. After selecting kernel
in GRUB, the monitor simply turns off because there is no signal. I've tried
with both D-Sub and HDMI outputs. I can attach any logs you need.

So, does 'Kernel Version: >3.2' and 'Regression: Yes' mean this worked with 3.2
kernels but is broken with newer ones? If so, can you bisect?

Please attach the dmesg output corresponding to the problem.

Sorry, my mistake, I meant >=3.2
I wrote "3.2" because 12.04 has 3.2 kernel. There is one confusing thing: the
driver works well now in Fedora 16 with the latest 3.3.4 kernel.

Okay, I finally discovered what is going on here.
First of all, now this bug seems to be reproducible only with D-Sub output. My
motherboard is ASRock A75M, monitor is LG E2360. Everything works very well
(and with a good hardware acceleration) on all kernel versions if I connect my
monitor with an HDMI cable.

If I connect it with D-Sub cable:
Bug is reproducible with: default 12.04 LTS kernel, and with 3.3.0; 
it is NOT reproducible on the latest 3.3.4.

So, with the latest 3.3.4 kernel I have a good hardware acceleration without
having to boot with nomodeset.

Though this problem seems to be solved in latest stable kernel, I attach the
/var/log/messages file I copied from hard drive with F17 with 3.3.0 kernel,
just after encountering this bug.

Sorry for my English.

You need this kernel patch to get VGA ports with DP bridges working:
