Created attachment 1215939 [details] Unknown Display +++ This bug was initially created as a clone of Bug #1374385 +++ Description of problem: After kernel upgrade, my screen is unrecognized. It is marked as "Unknown display" in Settings, the resolution is wrong and the graphic performance is very low. There are only two available resolutions by now : - 1024x768 (4:3) - 800x600 (4:3) Before this upgrade, there were plenty other resolutions, including the ideal one for my screen which is 1366x768, now unavailable. As mentioned before, my graphic performance is now very low. As an example, Minecraft used to run at ~60FPS, but now only runs at ~6FPS. Version-Release number of selected component (if applicable): the bug appeared first when I upgraded to kernel-4.6.7-300.fc24.x86_64 and is still present in kernel-4.7.2-201.fc24.x86_64. The last kernel without this bug is kernel-4.5.5-300.fc24.x86_64, which I'll keep installed and use as my default kernel until the problem is resolved. Additional info: My graphic card is an ATI Radeon HD 7670M. In "lspci", it is named "01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series]". Result of "uname -a" with the last kernel with this bug : "Linux fedora-l850-15z 4.7.2-201.fc24.x86_64 #1 SMP Fri Aug 26 15:58:40 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux". I also attached a screenshot of the display settings.
This message is a reminder that Fedora 24 is nearing its end of life. Approximately 2 (two) weeks from now Fedora will stop maintaining and issuing updates for Fedora 24. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '24'. 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 24 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 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is no longer maintained, which means that it will not receive any further security or bug fix updates.
