[SOLVED] Issue with wide resolution & latest X prackages [RX460] [KDE]

Hi,

2 problems that I do not know if those are related.

Since a week, I have lost my max resolution 2560x1080, I get only 1920x1080 detected.

When trying to update the package, I got conflict with some package

:: Synchronizing package databases...
 core is up to date
 extra is up to date

I will look more closely on this xorgproto ....

Any idea?

removing libxfont fixed the conflict issue but still stuck in 1920x1080 ...

The selection appears in KDE screen resolution settings ... but does not work
xrandr --output DVI-D-0 --mode "2560x1080_60.00"

Re: [SOLVED] Issue with wide resolution & latest X prackages [RX460] [KDE]

I have the same problem. I'm removing libxfont to see if it's solving it. The resolution issue might be related to an old video card driver for you, I think.

After a reboot, it worked with 4K resolution

Re: [SOLVED] Issue with wide resolution & latest X prackages [RX460] [KDE]

indeed removing libxfont worked ... for the resolution I am using open source driver so should be up to date unless there is a bug in latest mesa package (end of january)

So 2560x1080 not detected by default ... no problem under windows 10
Using DVI-D connection.

I tried to reduce frame rate to 50Hz ... did not help.

Re: [SOLVED] Issue with wide resolution & latest X prackages [RX460] [KDE]

There might be some problems with the new DC code added in  kernel 4.15, try booting with the kernel parameter

amdgpu.dc=0

Great thanks!

That was it.

What is this DC code about?

Proper support for HDMI/DP audio output is probably the biggest thing and afaik certain cards absolutely require it for display, but it seems to have problems with HIDPI / bigger resolutions in general.

Thanks for the explanation ... I will check if there is already a bug opened for the kernel.

Re: [SOLVED] Issue with wide resolution & latest X prackages [RX460] [KDE]

Thanks for point it out. I was anyway going to test it again when 4.16 hits the stable stage in few weeks.

Side question:
how do you know which bug list to check? For example when I got the hint this was related to kernel module, the kernel list sound logical ... I have no clue what is the scope for the actual freedesktop list ....

I didn't, found it through web searches on this bug's symptoms.

Here it is: https://bugs.freedesktop.org/describecomponents.cgi
Apparently, developers of this particular kernel module (amdgpu) are active in freedesktop.org bugtracker.

FYI

It seems it works out of the box with 4.16.3-1-ARCH. I did not have to set

amdgpu.dc=0
