Description Rodd Clarkson 2014-02-08 05:33:50 UTC
Description of problem:

I have a Samsung TV connected to a Onkyo receiver and then my computer using HDMI cables.  The computer doesn't seem to know it's connected to the Samsung TV, and thinks that the display is a 7" display.  As a result the UI is way to clunky.


Version-Release number of selected component (if applicable):

Up-to-date


How reproducible:

Everytime it starts

Comment 1 Steven Miano 2014-03-19 22:41:33 UTC
This seems like it should be a medium severity issue with X not resolving the display size correctly.

Comment 2 Jérôme Glisse 2014-03-19 23:13:33 UTC
What exactly is the issue, TV reconize as 7" and not as 40" does not mean anything. Where do you see the 7" ? What is the result on the TV ? Is there no picture ? Is it using wrong resolution ? Does it work if TV is connected directly without the Onkyo receiver in btw ? What is the GPU you are using ? Is it a laptop ?

Also attach Xorg log and kernel dmesg.

Comment 3 Steven Miano 2014-03-19 23:35:18 UTC
Not the TV, but the receiver is recognized as a 7" device when it should not be (in Gnome Shell v 3 settings).

Resolution on the display ends up being 1920x1080@60hz, but the size in `xrandr -q` shows 160mm x 90mm (which is clearly incorrect for many sized displays that you would attach to an audio video receiver).

I believe I have corrected this before by putting an additional file in:

/etc/X11/xorg.conf.d/<10-somefilenamehere.conf>

and statically setting the screen size that fits (so that GUI objects are scaled correctly on the resolution).

I'll add additional screenshots, Xorg log, and kernel dmesg as soon as I am finished configuring this unit.

Comment 4 Steven Miano 2014-03-20 00:23:52 UTC
In order to fix this issue steps I took (which worked immediately):

sudo yum install dconf-editor

dconf-editor

Traverse:

org -> gnome -> desktop -> interface 

Edit: scaling factor from 0 to 1.

Comment 5 Rodd Clarkson 2014-04-01 11:06:46 UTC
Okay, I've seen this twice now.

The first was the Onkyo Receiver and Samsung 40inch display initially in the report.

The second is a 26 in samsung display (with out a receiver in between).

I'll try to get xorg log and kernel dmesg for both, but here's answers to your other questions.

In both cases, in the Displays option in Settings when you click on the screen in questions, the dialog says it's a 7" display (but gets the pixels right - in on case 1920x1080 and the other 1280x768 i think).

The GPU in both are Intel series GPU's.

lspci shows:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

and I think the other is the same (or very similar).

What happens in both cases is that all the elements on the screen are very large.  The settings dialog, for example, is larger than the desktop and very hard (read impossible) to use on the screen (even if it was actually a 7" display).

Hi,

I have similar problem, I have 27'' monitor which reports it is 160 x 90 mm. 

The scaling factor is only workaround and a bad one, because gnome use it only for part of it's gui.

I think some monitors report bad display size and xorg take it for granted.

I tried this in xorg.conf.d but without help:
Section "Monitor"
    Identifier             "Monitor0"
    DisplaySize             337 598    # In millimeters
EndSection

Comment 9 Fedora End Of Life 2015-05-29 10:51:09 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 10 Steven Miano 2015-05-31 03:47:05 UTC
This is still happening in Fedora 22 (WorkStation).

Comment 11 Fedora End Of Life 2015-06-29 15:05:07 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
