I'm facing same issue. I thought that is the JetBrains software update issue, because I updated PHPStorm to 2020.1 I have two different issues. Only PHPStorm freezes or whole system freezes. *** Log for PHPStorm freeze: *** Apr 30 11:18:57 XXXX gnome-shell[4130]: Could not create selection source for X11: Format TARGETS not supported Apr 30 11:20:08 XXXX kernel: [11685.466519] [UFW BLOCK] IN=wlp2s0 OUT= MAC=01:00:5e:00:00:01:70:4f:57:55:f3:38:08:00 SRC=192.168.1.1 DST=224.0.0.1 LEN=36 TOS=0x00 PREC=0x00 TTL=1 ID=0 DF PROTO=2 Apr 30 11:22:12 XXXX kernel: [11809.996191] [UFW BLOCK] IN=wlp2s0 OUT= MAC=01:00:5e:00:00:01:70:4f:57:55:f3:38:08:00 SRC=192.168.1.1 DST=224.0.0.1 LEN=36 TOS=0x00 PREC=0x00 TTL=1 ID=0 DF PROTO=2 Apr 30 11:22:28 XXXX kernel: [11825.857676] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 30 11:18:59 XXXX gnome-shell[4130]: message repeated 7 times: [ Could not create selection source for X11: Format TARGETS not supported] Apr 30 11:22:28 XXXX jetbrains-phpstorm.desktop[4130]: 2020-04-30 11:22:28,719 [7663939] WARN - .diagnostic.PerformanceWatcher - UI was frozen for 7585ms, details saved to /home/grego/.cache/JetBrains/PhpStorm2020.1/log/threadDumps-freeze-20200430-112226-PS-201.6668.153-XlibWrapper.XQueryPointer-7sec *** Log for system freeze: *** Sometimes have two lines: Apr 30 08:33:53 XXXX kernel: [ 1710.739980] i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0 Apr 30 08:33:53 XXXX kernel: [ 1710.740998] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Sometimes second line appears alone: Apr 30 13:50:14 XXXX kernel: [20691.862458] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871867 Title: i915: GPU HANG: ecode 9:0:0x00000000, hang on rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1871867/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
