[Kernel-packages] [Bug 1799613] Re: In kernel 4.14.59, monitor resolution is detected correctly. In kernels after that, they are not detected correctly.

2024-03-01 Thread Erik Granger
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.

[Kernel-packages] [Bug 1799613] Re: In kernel 4.14.59, monitor resolution is detected correctly. In kernels after that, they are not detected correctly.

2021-12-06 Thread Erik Granger
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.

Cristian, please stop creating upstream bugs for other people.

Some of your bug reports are invalid, and even the valid ones need to be
created by the person who was experiencing the bug. Because they are the
ones who will need to answer questions and own the upstream bug.

please enter the following command in a terminal window:

apport-collect -p xorg 1799613

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable
to run this command, please add a comment stating that fact and change

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 (""). Leave any other parameters as they 
>are. For example, you may end up with a line like this:

>GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dc=0"
>Save the file and exit, and then run

>sudo update-grub
>to write the configuration, and reboot.

After doing this, the resolution is detected correctly and appears
normal in the 4.15.0-38-generic kernel.

This bug is missing log files that will aid in diagnosing the problem.
While running an Ubuntu kernel (not a mainline or third-party kernel)
please enter the following command in a terminal window:

apport-collect 1799613

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable
to run this command, please add a comment stating that fact and change
the bug status to 'Confirmed'.

22:11:45 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

When running this kernel, the bug changes but is still present. In
arandr, the 2560x1440 resolution is available, however the monitor
interprets the signal as 1280x1440, which makes everything look wonky
and unreadable. Is this considered the same bug, and should I market as
'kernel-bug-exists-upstream'?

2018-10-24 Thread Cristian Aravena Romero
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.
