Recently, I have begun to have recurring issues with my Linux Mint 18.1 system seeming to get "stuck" and I can't figure out why. I leave my system running 24/7 and have rarely had a reason or need to shut down. It has now been running (mostly fine) for 10 days. The recent problems have happened with both the chrome browser and the firefox browser (open at separate times). Various symptoms include the screen seeming to "freeze" sometimes with the cursor pointer disappearing, sometimes it changes to an "I" instead of an arrow pointer and is either unmovable on the screen or sometimes it can be moved, but at a drunken snail's pace. Sometimes the screen goes blank and if I walk away and come back after several minutes, the screen is restored and the cursor can be moved again. I have uploaded a screen shot and two text files as examples, including top.txt ... ps-ef.txt ... and a couple of screen shots. Can someone tell me what processes ps-ef show that should be or could be killed? Why does top-txt show two instances of chrome running ?? Why does top whoc 4 users when 'who' shows only 3? And why are there 3 users when I am the only user? http://www.upquick.com/temp/freeze.jpg http://www.upquick.com/temp/top-txt http://www.upquick.com/temp/ps-ef.txt t420: who joe tty8 2018-02-28 14:39 (:0) joe pts/2 2018-05-22 15:43 (:0) joe pts/5 2018-02-28 14:40 (:0) top - 15:47:20 up 170 days, 5:29, 4 users, load average: 0.22, 1.01, 10.65 Tasks: 245 total, 2 running, 235 sleeping, 0 stopped, 8 zombie %Cpu(s): 5.0 us, 1.3 sy, 0.0 ni, 93.6 id, 0.1 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem: 8056428 total, 3870692 used, 4185736 free, 134676 buffers KiB Swap: 1951740 total, 1769720 used, 182020 free. 1161048 cached Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 10665 joe 20 0 3832944 239268 63624 S 11.9 3.0 6649:51 plasma-desk+ 15697 joe 20 0 511896 50588 35968 S 5.3 0.6 0:05.17 konsole 10241 root 20 0 419892 148588 99172 S 4.0 1.8 1567:26 Xorg 10659 joe 20 0 3247440 90844 18280 S 0.7 1.1 642:54.34 kwin 18274 joe 20 0 1841712 181908 16 S 0.7 2.3 50:10.02 chrome ***** (1) 8 root 20 0 0 0 0 S 0.3 0.0 75:00.93 rcuos/0 487 root -51 0 0 0 0 S 0.3 0.0 464:58.53 irq/44-iwlw+ 1174 root 20 0 4388 224 100 S 0.3 0.0 112:21.59 acpid 14574 root 20 0 0 0 0 S 0.3 0.0 0:00.42 kworker/u16+ 15757 joe 20 0 24964 3168 2568 R 0.3 0.0 0:00.81 top 31023 joe 20 0 1752576 36352 0 S 0.3 0.5 149:49.69 chrome ***** (2) 1 root 20 0 37500 2096 0 S 0.0 0.0 0:14.22 init 2 root 20 0 0 0 0 S 0.0 0.0 0:03.73 kthreadd 3 root 20 0 0 0 0 S 0.0 0.0 10:32.60 ksoftirqd/0 5 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 kworker/0:0H 7 root 20 0 0 0 0 S 0.0 0.0 136:59.67 rcu_sched 9 root 20 0 0 0 0 S 0.0 0.0 23:30.73 rcuos/1 10 root 20 0 0 0 0 S 0.0 0.0 44:27.97 rcuos/2 11 root 20 0 0 0 0 S 0.0 0.0 25:53.54 rcuos/3 12 root 20 0 0 0 0 S 0.0 0.0 0:00.01 rcuos/4 13 root 20 0 0 0 0 S 0.0 0.0 0:00.01 rcuos/5 14 root 20 0 0 0 0 S 0.0 0.0 0:00.01 rcuos/6 15 root 20 0 0 0 0 S 0.0 0.0 0:00.01 rcuos/7 16 root 20 0 0 0 0 S 0.0 0.0 0:00.00 rcu_bh --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.phxlinux.org To subscribe, unsubscribe, or to change your mail settings: http://lists.phxlinux.org/mailman/listinfo/plug-discuss
