Public bug reported: Newly installed Ubuntu 19.04 system. AMD Ryzen 3700X. NVIDIA GeForce RTX 2060.
When the system is left for a while and the screen goes to sleep, then sometimes but not always, upon return there is no reaction to keyboard and mouse. Most likely the system is still running fine, but the only thing one can do is reboot. Afterwards, /var/log/kern.log shows lines like Sep 15 21:50:50 if kernel: [35590.756691] nouveau 0000:07:00.0: DRM: core notifier timeout Sep 15 21:50:52 if kernel: [35592.756660] nouveau 0000:07:00.0: DRM: wndw-0: timeout Ubuntu 5.0.0-27.28-generic 5.0.21 $ sudo lspci -vnvn > lspci-vnvn.log pcilib: sysfs_read_vpd: read failed: Input/output error ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Attachment added: "lspci-vnvn.log" https://bugs.launchpad.net/bugs/1844072/+attachment/5288871/+files/lspci-vnvn.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1844072 Title: nouveau core notifier timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1844072/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
