Description Lukáš Polívka 2018-04-06 20:28:10 UTC
Description of problem:
Tried booting with a new (current) kernel.

I can boot fine-ish with 4.14.11-300.fc27.x86_64 (hardware acceleration does not seem to work as glxinfo only reports llvime OpenGL driver), but even later (current) fc27 kernels (4.15-ish) would hang.
Same thing with fc28 beta now.

I have a ThinkPad T420 with Nvidia Optimus. I'll need to (re-)test if enabling/disabling Optimus and/or enablind/disabling the Intel VT-d in BIOS and similar tricks help.

Comment 2 Lukáš Polívka 2018-04-13 14:45:31 UTC

Indeed, when I disabled Nvidia Optimus and Intel VT-d I could at least boot the system, although OpenGL would still fall back to llvmpipe.

But with the current kernel 4.16.1-300.fc28.x86_64 I can re-enable Optimus (+Optimus OS detection) and VT-d and boot the system successfully and even get proper OpenGL support on both GPUs.

The only small glitch/issue is that now the bootsplash resolution / aspect ratio is not correct. The resolution is too low for my 1600 x 900 display and the aspect ratio is probably 4:3 stretched to my display's 16:9. (I'm ashamed to even mention this.)

Anyways, I like the progress. Years ago I could not boot Fedora on this laptop without ACPI workarounds, turning off Optimus and VT-d and now it's working out of the box. Good work!

This message is a reminder that Fedora 28 is nearing its end of life.
On 2019-May-28 Fedora will stop maintaining and issuing updates for
Fedora 28. 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that are no longer maintained.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 '28'.

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 28 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 4 Ben Cotton 2019-05-28 19:53:52 UTC
Fedora 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 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

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