In fact I'm already on 387.22 which, I see from a nearby post on the same forum, has the same fix: https://devtalk.nvidia.com/default/topic/1025794/unix-graphics- announcements-and-news/linux-solaris-and-freebsd-driver-387-22/
It hasn't helped. TBH I don't think it applies as (fx: me reading up more on what PRIME sync is) I don't think I'm using PRIME sync... my mobo has integrated Intel HD4600 as well but I don't use it at all, and the nvidia card is selected as default in uefi bios. I've done no prime sync setup at all. There appear to be a shedload of upstream gnome-shell bugs relating to these problems, and not everyone having them is using nVidia, though it may be that they are all using DisplayPort to connect to their monitors, although why something as user-level as gnome-shell is bothered with *which* ports are used is beyond me... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1723615 Title: gnome-shell crashed with SIGSEGV in meta_monitor_mode_get_resolution() Status in gnome-shell package in Ubuntu: Confirmed Bug description: This happened while I was away from the computer. By the timing it should have been well after the time it should have gone *into* displaysleep, and was also about 45min before I returned, so certainly wasn't the wake-up process either. What I observed when I did return: My 4K monitor didn't wake up (that's a known problem with this monitor, Dell P2715Q), the second monitor (Dell U2711) did wake up, showing the login screen. So although I've considered my Dell 4K problem a problem with waking up, I wonder if it might be actually a problem with it apparently going away completely after a longer displaysleep (it's usually fine if I just do a short sleep of a minute or two). Another possibility is the cat stepped on the keyboard and thus triggered an attempted display-wake. But that would actually be out of character (for the cat). Either way is a bug because the session should survive monitor shenanigans... :-) ProblemType: Crash DistroRelease: Ubuntu 17.10 Package: gnome-shell 3.26.1-0ubuntu3 ProcVersionSignature: Ubuntu 4.13.0-16.19-generic 4.13.4 Uname: Linux 4.13.0-16-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia_drm nvidia_modeset nvidia ApportVersion: 2.20.7-0ubuntu3 Architecture: amd64 CurrentDesktop: GNOME-Greeter:GNOME Date: Sat Oct 14 15:39:50 2017 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: InstallationDate: Installed on 2017-07-30 (75 days ago) InstallationMedia: Ubuntu-GNOME 17.04 "Zesty Zapus" - Release amd64 (20170412) ProcCmdline: /usr/bin/gnome-shell ProcEnviron: LANGUAGE=en_GB:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_GB.UTF-8 SHELL=/bin/false SegvAnalysis: Segfault happened at: 0x7fae20ab44a0 <meta_monitor_mode_get_resolution>: mov 0x8(%rdi),%eax PC (0x7fae20ab44a0) ok source "0x8(%rdi)" (0x00000008) not located in a known VMA region (needed readable region)! destination "%eax" ok SegvReason: reading NULL VMA Signal: 11 SourcePackage: gnome-shell StacktraceTop: meta_monitor_mode_get_resolution () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 meta_monitor_calculate_mode_scale () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 meta_monitor_manager_update_logical_state_derived () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 meta_monitor_manager_rebuild_derived () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 meta_monitor_manager_xrandr_handle_xevent () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 Title: gnome-shell crashed with SIGSEGV in meta_monitor_mode_get_resolution() UpgradeStatus: Upgraded to artful on 2017-08-22 (53 days ago) UserGroups: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1723615/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
