dmesg snippet after boot
Description of problem:
Unable to use discrete graphics card:
01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330]
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Follow the procedure descibed here: https://fedoraproject.org/wiki/QA:Testcase_vga_switcheroo
End up with a black screen and an unresponsive keyboard/machine.
Be able to load gnome using the RADEON card
This is happening on a Dell Inc. Latitude E6440/007KGN, BIOS A10 02/02/2015
I'm actually able to lunch stuff on the discrete graphics by using the DRI_PRIME=1 variable.
Here's the output of that.
nmreis@e6440c-laptop ~]$ DRI_PRIME=1 glmark2
GL_RENDERER: Gallium 0.4 on AMD HAINAN (DRM 2.43.0, LLVM 3.7.0)
GL_VERSION: 3.0 Mesa 11.0.0 (git-c4bae57)
Assigning to the right component
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. 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bug reports from releases that are no longer maintained.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'
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 23 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.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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no longer maintained, which means that it will not receive any further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.
