Description Renich Bon Ciric 2014-07-13 01:21:39 UTC
Created attachment 917584 [details] lspci Description of problem: If I append radeon.dpm=1 to the kernel at boot time, 3d acceleration is affected. It prevents GDM, KDM or XDM to work. The only one that seems unnaffected is LightDM since it doesn't use it. It makes it impossible to use Gnome, KDE or any 3d accelerated desktop. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-7.2.0-3.20131101git3b38701.fc20.x86_64 How reproducible: Use radeon and enable dpm. Reboot a few times. Most of the time, gdm will not work at all (it works sometimes). Remove it and it will work. Additional info: This problem happens begining kernel 3.14.x until today; 3.15.3 at the moment. If I don't use dpm, my video card starts overheating. I can't even get passed installation if it is not enabled. The only fix I have left is the following, but it makes my graphics clumsy: echo profile > /sys/class/drm/card0/device/power_method echo low > /sys/class/drm/card0/device/power_profile
Comment 3 Fedora End Of Life 2015-05-29 12:21:31 UTC
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '20'. 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 20 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.
