In comment 28, the freeze happened just before taking the log, yet the last log entry was from ~1 minute earlier, so it doesn't look like there were any relevant log entries.
However just now I had a freeze, and there are some messages in dmesg: [10980.231902] perf: interrupt took too long (2512 > 2500), lowering kernel.perf_event_max_sample_rate to 79500 [11986.082217] perf: interrupt took too long (3142 > 3140), lowering kernel.perf_event_max_sample_rate to 63500 [16384.901113] perf: interrupt took too long (3928 > 3927), lowering kernel.perf_event_max_sample_rate to 50750 Also in journalctl -b0: May 20 22:30:09 daniel-XPS-13-9380 kernel: perf: interrupt took too long (3928 > 3927), lowering kernel.perf_event_max_sample_rate to 50750 The previous journalctl message is from a few minutes prior. Searching for the error message suggests that perhaps these messages aren't any major cause for concern though. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1827791 Title: Dell XPS 13 9380 - Screen and input freezes / hangs temporarily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1827791/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
