You have been subscribed to a public bug: On at least Ubuntu 15.10 and 16.04 with the radeon driver (version 7.5.0+git20150819-0ubuntu1 on 15.10, version 7.6.1-1ubuntu2 on 16.04) trying to suspend or hibernate a Lenovo G50-80 with Intel HD Graphics 5500 (Broadwell GT2) and Advanced Micro Devices [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330] freezes the system when the radeon driver is loaded even if it is not in use. Turning off discrete graphics using the BIOS settings and using only the integrated Intel chip so that the radeon driver is not loaded does not cause this problem. Also, this problem does not occur on Ubuntu 14.04.4 using the kernel and X stack (LTS Enablement Stack) from 15.10 (Wily) even with the radeon driver loaded.
There is a message from the radeon driver during boot, "radeon 0000:04:00.0: VCE init error (-22)." which is an upstream issue occurring on other distributions too and is reported at https://bugs.freedesktop.org/show_bug.cgi?id=92722. However, even if the radeon driver is loaded, suspend/hibernate does not freeze on, e.g., Fedora 23 and, as mentioned above, even Ubuntu 14.04.4. I have tried using S1 instead of S3 sleep to no avail. ** Affects: xorg (Ubuntu) Importance: Low Status: Incomplete ** Tags: hibernate suspend wily xenial -- Suspend/hibernate freezes with radeon driver loaded on AMD/ATI hybrid graphics https://bugs.launchpad.net/bugs/1565729 You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
