[Kernel-packages] [Bug 1799613] Re: In kernel 4.14.59, monitor resolution is detected correctly. In kernels after that, they are not detected correctly.
Hello, Every time I re-image my computer, I have to frantically search the internet for this bug report to fix this issue. It is now 5 years after the initial bug report, and it is still unfixed. Since then, I've upgraded my CPU and my RAM and swapped out a new video card (still an AMD but a newer fancier 590 instead of that lowly POS 560). I've also bought a house, and had 2 children with an option on a third, I've experienced major life changes, I've laughed, I've cried, and I've grown. Life is full of changes, some for the better and some for the worse, but change is inevitable, it's built into the very nature of our world, but it is good to know that some things never change. I don't know if I'm the only person on the planet who runs into it, I don't know what amd.dc=0 means, but to celebrate the release of Plasma 6 I ran this fix again. I hope that, in 2 or 4 or 10 years, if I'm still using these same monitors, I'll still run into this issue, and this belief now binds me, grounds me, humbles me, and keeps me oriented. This bug is my North Star. When I have to re-find this thread in order to remember what it is I have to do to work around this issue, I know that the tempest, for a moment, is o'er, and that I am anchored in bug divine. Maybe one day I'll learn what amd.dc=0 does, and why it needs to be added to grub, but it is not this day. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1799613 Title: In kernel 4.14.59, monitor resolution is detected correctly.

Hello, I am still having this issue. Adding amdgpu.dc=0 to the grub config "fixes" it, but with the side-effect that startup text is illegible (for some reason). This would make it hard if I ever had to restore my system after a failed launch of the session manager or something like that. I now have an rx590, but the same monitors. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1799613 Title: In kernel 4.14.59, monitor resolution is detected correctly.

I think that fixed it. To add `amdgpu.dc=0`, you must edit your grub configuration https://askubuntu.com/questions/1029517/amd-rx480-screen-flicker-after- update-to-18-04#1032198 >To do this, edit the file /etc/default/grub, for example using >sudoedit /etc/default/grub >Find the line beginning GRUB_CMDLINE_LINUX_DEFAULT and add the text >amdgpu.dc=0 between the double quotes ("").

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.19 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
