Wrong color depth on Radeon HD 6770

[Michael Poly]

Graphics card is Radeon HD 6770. X.Org drivers. Clean install, video works but color depth is < 24bpp. I tried adding DefaultDepth parameter on xorg.conf. Secondary card is integrated on the motherboard (Intel E3-1200 chipset). Delivers 24bpp right away, no tinkering required.

Michael P, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1338068

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.

Thank you for your understanding.

Hi, thanks for looking into this. I just did the following:

- Downloaded latest from daily-live/current
- Created bootable USB
- Switched cables to connect monitor to Radeon card
- Booted with bootable USB
- Confirmed that the problem persists (by viewing photos with a blue sky
   background and noticing the color gradient)
- run apport-collect (which posted a total of 19 logs on launchpad)

Please let me know if there is anything else I can do to help

Best regards,

Michael

Michael P, does using fglrx provide a WORKAROUND to this issue?

[Michael Poly (mpoly)]

fglxr gave me a really hard time to start on the daily build (I can provide details if needed). In any case, it didn't work, result was same.

[penalvch (penalvch)]

Michael P, what version of fglrx specifically did you try to install?

[Michael Poly (mpoly)]

fglrx-updates (2:14.501-0ubuntu1)

   ubuntu@ubuntu:~$ fglrxinfo
   display: :0 screen: 0
   OpenGL vendor string: Advanced Micro Devices, Inc.
   OpenGL renderer string: AMD Radeon HD 6700 Series
   OpenGL version string: 4.4.13283 Compatibility Profile Context 14.501.1003

let me know if you need me to runn apport-collect while using the fglrx-updates

In case it helps: The system is dual-adaptor, dual-display AMD/Intel.
Identical Philips 233V monitors on both cards. The Intel card has
correct color depth.

Thanks, m

To clarify previous comment: After giving me a hard time, fglrx did install, but gave the same result as the open driver (i.e. color depth was visibly less than 24bpp)

[Timo Aaltonen (tjaalton)]

[ 37.738] (II) RADEON(0): Creating default Display subsection in Screen section
 "Default Screen Section" for depth/fbbpp 24/32
[ 37.738] (==) RADEON(0): Depth 24, (--) framebuffer bpp 32
[ 37.738] (II) RADEON(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp pixmaps)
[ 37.738] (==) RADEON(0): Default visual is TrueColor
[ 37.738] (==) RADEON(0): RGB weight 888
[ 37.738] (II) RADEON(0): Using 8 bits per RGB (8 bit DAC)

your eyes are lying :)

Well I'm calling my computer a liar... (I guess I'll now have to keep an
eye on it, lest it decides, like HAL did, to take me out)

Yes, I had noticed that the log claims 24, but it is clear when I view
a picture with a gradient that the depth is less. It is also visible in
the shading of the Unity GUI elements.

If I slide the picture across to the other monitor (same model, attached
to an Intel card), it displays correctly.

[Michael Poly (mpoly)]

Not sure why this was changed to invalid. The log does (falsely) indicate 24bpp, but that's not what is being displayed.

[penalvch (penalvch)]

Michael P, to see if this is already resolved in Ubuntu, could you please test for this via http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[Launchpad Janitor (janitor)]

[Expired for xorg (Ubuntu) because there has been no activity for 60 days.]

[Michael Poly (mpoly)]

For what it's worth: The problem was resolved upon upgrading to Ubuntu 16.04; The Radeon now gives full color depth upon install.
