Just as an update, in the Freedesktop issue, I found using a LOWER specced/older cable to fix the problem. I do not know how to debug it further but I suspect the bug is in the support of later version of the HDMI standard. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761751 Title: Black screen on 18.04 + AMD RX460 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761751/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1761751] Re: Black screen on 18.04 + AMD RX460
I'm getting exactly this issue. An ATI RX 480 on Kubuntu 18.04 with a ASUS MG28U on HDMI-1. It is on a 5m cable so using the displayport wasn't an option. The long HDMI cable is to allow the large system box to be away from my desk. I mostly use the system as a web and data server and it is stuffed with hard drives. Works perfectly on 4.13 kernels. Fails on the 4.15 kernels before the sddm login screen. 4.15.0-43-generic <-- screen repeats HDMI no signal 4.15.0-42-generic <-- screen repeats HDMI no signal 4.15.0-35-generic <-- screen repeats HDMI no signal 4.13.0-36-generic <-- ok On 4.13 kernels it runs the screen at 3840x2160 @ 30Hz. On 4.15 kernels it doesn't. At a guess looking at the syslog, the 4.13 fell back to 30Hz at the hi- res while the 4.15 does not. Over the long cable the screen isn't detecting the screen at 60Hz. Hope that helps. I may have to look at getting a longer active cable... ** Attachment added: "syslog_fragment_4.15.0.43.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761751/+attachment/5221404/+files/syslog_fragment_4.15.0.43.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761751 Title: Black screen on 18.04 + AMD RX460 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761751/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 1761751] Re: Black screen on 18.04 + AMD RX460
I booted the 4.17rc1 kernel. In order to see output I connected an old TV to the DVI output, and that output was successfully detected (through an DVI-HDMI adapter, if that matters). The output of /sys/class/drm/card0-HDMI-A-1 in this case: dpms: Off enabled: disabled modes: (empty) status: disconnected I then tried switching which monitor was connected to which port. Interestingly, in this case both the Dell U2415 and the old TV could show output successfully. // David On 2018-05-02 19:50, Harry Wentland wrote: > Thanks, mind posting the same for the non-working kernel?

I'm not sure if you asked for the contents of these files from a working or non-working kernel, but I'll take the working kernel since that's obviously a lot easier.

Anyway, I did some research on my own as well. First, I had a look at the commits between 4.15rc2 and 4.15rc3. The only one I could see being relevant is this one: commit a703c55004e1c5076d57e43771b3e7796ea0 Author: Daniel Vetter Date: Mon Dec 4 21:48:18 2017 +0100 drm: safely free connectors from connector_iter ...it seems relevant because the error I get is "Cannot find any crtc or sizes", and the code emitting this error message (in drivers/gpu/drm/drm_fb_helper.c) deals with connectors. This commit is then referenced in other commits later on as being required to fix, but since 4.16 is "black screen" too those fixes seems not have helped here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761751 Title: Black screen on 18.04 + AMD RX460 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761751/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1761751] Re: Black screen on 18.04 + AMD RX460
I started a kernel bisect between v4.15-rc2 and v4.15-rc3. The kernel bisect will require testing of about 7-10 test kernels. I built the first test kernel, up to the following commit: 78d9b048446c3c0a83313444fb706f8f3bccdae7 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1761751 Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

[Bug 1761751] Re: Black screen on 18.04 + AMD RX460
I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue. Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug: v4.14 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/ v4.15-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc1/ v4.15-rc5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc5/ v4.15-rc9: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc9/ v4.15 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15/ v4.16-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16-rc1/ You don't have to test every kernel, just up until the kernel that first has this bug.
