gregrwm: >"i am not asking for help." If you are not expecting this bug to be fixed (i.e. not asking for a developer to help), then feel free to mark this report Status Invalid. Otherwise, please refrain from "smart alec" remarks, as it doesn't motivate developers to want to fix bugs you report.

[Bug 1757299] Re: [Dell OptiPlex 755] xorg hangs
i am not asking for help. this is a bug report. i am reporting a bug. if there is useful information i can gather i am happy to do so. 4) the steps in the description of this bug were performed in fairly rapid succession, so several apps were busy starting up. The lockup occurred instantly after maximizing the xterm. 6) killing Xorg freed the terminal. 3) it is not consistently reproducible. Under xenial it happens watching videos (Bug #1744429). Since installing bionic, videos haven't tripped it so far. This bug report describes an occurrence that didn't involve a video. 5) here is what htop looks like right after logging in, launching startx, 2 xterms, and htop: 0 [ 0.0%] Tasks: 37; 1 running [0/0] 1 [ 0.0%] Load average: 0.12 0.30 0.15 Mem[ 122M/1.90G] Time: 15:54:56 Swp[ 0K/1.86G] PID START USER VIRT RES NI CPU% TIME+ S Command 1 15:51 root 155M 8996 1 0.0 0:01.92 S /sbin/init 253 15:51 root 86576 18424 0 0.0 0:01.16 S /lib/systemd/systemd-journald 543 15:51 syslog 252M 4576 0 0.0 0:00.99 S /usr/sbin/rsyslogd -n 828 15:52 g 242M 23468 0 0.0 0:00.53 S /usr/lib/xorg/Xorg -nolisten tcp :0 vt1 278 15:51 root 47348 5788 0 0.0 0:00.51 S /lib/systemd/systemd-udevd 549 15:51 root 280M 6952 0 0.0 0:00.12 S /usr/lib/accountsservice/accounts-daemon 769 15:53 g 29276 7588 0 0.0 0:00.09 S -bash 980 15:54 root 61440 4228 0 0.0 0:00.09 S sudo -H -uG -s 953 15:54 g 29308 7452 0 0.0 0:00.08 S -bash 893 15:52 g 28304 6432 0 0.0 0:00.06 S bash 1005 15:54 root 28136 6464 0 0.0 0:00.06 S /bin/bash 550 15:51 root 417M 9020 0 0.0 0:00.05 S /usr/sbin/ModemManager 551 15:51 messagebu 50088 4664 0 0.0 0:00.05 S /usr/bin/dbus-daemon --system --address= 871 15:52 g 86456 10504 0 0.0 0:00.05 S xterm 890 15:52 g 86456 10464 0 0.0 0:00.05 S xterm -bg black -fg white -rightbar -xrm 834 15:52 g 46120 5524 0 0.0 0:00.04 S x-window-manager F1Help F2Setup F3SearchF4FilterF5Tree F6SortByF7Nice -F8Nice +F9Kill F10Quit here is what htop looks like while quiescent after several hours of use: 0 [||| 5.3%] Tasks: 55; 1 running [0/0] 1 [||| 4.6%] Load average: 0.00 0.04 0.07 Mem[||1.11G/1.90G] Time: 15:22:36 Swp[ 0K/1.86G] PID START USER VIRT RES NI CPU% TIME+ S Command 1231 07:07 g 2605M 707M 0 0.7 30:52.86 S /usr/lib/firefox-esr/plugin-container -gr 1119 07:06 g 2385M 431M 0 7.3 12:13.72 S /usr/lib/firefox-esr/firefox-esr 883 07:05 g 348M 54372 0 0.0 1:39.51 S /usr/lib/xorg/Xorg -nolisten tcp :0 vt1 - 1051 07:06 g 1049M 10372 -11 0.0 1:31.19 S /usr/bin/pulseaudio --start --log-target= 1027 07:06 g 535M 41720 0 0.0 1:10.72 S pavucontrol 1023 07:06 g 832M 58800 0 0.0 0:10.06 S /usr/bin/python3 /usr/bin/blueman-manager 1058 07:06 g 70784 6520 0 0.0 0:03.05 S xclock -geometry --1+-4 -fg green -bg bla 1 06:51 root 155M 9016 0 0.0 0:02.93 S /sbin/init 925 07:05 g 86456 10456 0 0.0 0:02.80 S xterm 2600 15:18 root 28044 5228 0 0.7 0:01.45 R htop 889 07:05 g 46120 5704 0 0.0 0:01.38 S x-window-manager 253 06:52 root 86568 16580 0 0.0 0:01.13 S /lib/systemd/systemd-journald 544 06:52 syslog 252M 4508 0 0.0 0:01.06 S /usr/sbin/rsyslogd -n 280 06:52 root 47580 5940 0 0.0 0:00.55 S /lib/systemd/systemd-udevd 1070 07:06 g 648M 51880 0 0.0 0:00.43 S /usr/bin/python3 /usr/bin/blueman-applet 518 06:52 root 280M 7192 0 0.0 0:00.41 S /usr/lib/accountsservice/accounts-daemon F1Help F2Setup F3SearchF4FilterF5Tree F6SortByF7Nice -F8Nice +F9Kill F10Quit -- You received this bug notification because you are a
[Bug 1757299] Re: [Dell OptiPlex 755] xorg hangs
gregrwm, in order to help you, please review all of the following, and answer all questions: 1) Regarding all the reports you mentioned, they are useless as they don't contain useful information to root cause and solve. Hence, it is most helpful if you keep focus on this one report, versus making new reports, or constantly referencing others. 2) Please don't apport-collect or attach more apport-collect files. 3) Regarding the Bug Description, is this consistently reproducible using your steps? 4) Regarding the Bug Description, how long does it take from "maximized the xterm running tmux" to your GUI stops responding, seconds, minutes, etc.? 5) Immediately after logging in, without doing anything else what is the idle CPU utilization (htop results)? 6) After reproducing the problem, if you SSH in and kill processes, which processes do you have to kill until your GUI begins to be responsive again? ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete ** Description changed: + The problem is that my GUI stops responding after launching a few + applications, and is correlated to high CPU utilization of xorg. + + An example reproduction scenario: launched startx, launched an xterm via twm, launched another xterm via the first, launched tmux, launched firefox-esr, bluetooth-manager, and pavucontrol, maximized the xterm running tmux xorg stopped responding, ctl-alt-Fn don't respond either - logged in via ssh, attached to tmux, launched htop, copied htop output, in which you can see xorg consuming lots of cpu. - noticed twm no longer running - launched ubuntu-bug xserver-xorg - answered its question re display manager log files - i left it printing endless periods for over an hour - - killed xorg - launched startx again - started a second ubuntu-bug xserver-xorg - answered its questions re display manager log files and additional debugging work - - noticed the first ubuntu-bug xserver-xorg is no longer printing periods - answered its questions re additional debugging work and Send problem report - - attached copy of htop output + logged in via ssh, attached to tmux, launched htop, copied htop output, + in which you can see xorg consuming lots of cpu.
