Several times over the past month my t460s has just blank screens when I come back to it after some time. I don't know if the thing froze up completely or if it is just the display not working. I lock my screens (laptop + 2 external monitors) and then leave for an hour or so. When I come back no attempt at input will get the lockscreen to appear. I have to power down and then back up. After boot I look at the journal and I always tend to see some of these: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe C (start=167156 end=167157) time 146 us, min 1073, max 1079, scanline start 1072, end 1082 [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=488827 end=488828) time 107 us, min 1073, max 1079, scanline start 1072, end 1080 I'm not saying these are what is causing the issue but are at least something I noticed. I'll continue to monitor this problem. It only happens like once every two weeks so it is hard to prepare for it by knowing the IP address so that I can try to ssh in to see if the system is frozen or if it is just the screen. Has anyone else seen some behavior like this? I am using i3wm and my system is updated approximately once a week, so I should have close to the latest software installed.
