Hi, I also experience this problem with my laptop at resume from sleep.
About log messages, there does not seem to be a message when entering sleep. When resuming from sleep, I can briefly see this message printed on the screen: kernel: [drm:rv730_stop_dpm [radeon]] *ERROR* Could not force DPM to low However at boot time, I see this in the log: kernel: [drm] initializing kernel modesetting (RV710 0x1002:0x9553 0x1179:0xFF00). I see a switch from rv710 to rv730, is this normal? Previously, Thaddäus Tintenfisch reported a switch from rv730 to rv770... If useful, the lspci command says: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710/M92 [Mobility Radeon HD 4530/4570/545v] 01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] RV710/730 HDMI Audio [Radeon HD 4000 series] The patch proposed just before seems to be explicitely related to rv770, which does not seem to be my case. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1319589 Title: [drm:rv770_dpm_set_power_state] *ERROR* rv770_set_sw_state failed To manage notifications about this bug go to: https://bugs.launchpad.net/dri/+bug/1319589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
