[07:36] <DarkTrick> why would xubuntu user xflock4 for locking the screen instead of `dm-tool lock`?
[07:40] <JackFrost> dm-tool works specifically with lightdm/light-locker, xflock4 works with gnome-screensaver, mate-screensaver, xfce4-screensaver, light-locker, slock, xscreensaver...
[07:40] <astraljava> Damn, beat me to it by ' ' much.
[08:01] <DarkTrick> JackFrost, Thank you!
[08:41] <bill_> hi all!
[08:42] <bill_> I am meeting a slow disk(spin) issue
[08:42] <bill_> sudo hdparm --direct  -Tt  /dev/sdc
[08:43] <bill_> I run this command but result is like:
[08:43] <bill_> Timing O_DIRECT cached reads:   110 MB in  2.03 seconds =  54.12 MB/sec
[08:43] <bill_> Timing O_DIRECT disk reads: 174 MB in  3.14 seconds =  55.50 MB/sec
[08:43] <bill_> I think 5xMB/s is very very
[08:44] <bill_> What os I am using is Xubuntu 18.04
[09:44] <brainwash> bill_: and this problem only occurs with xubuntu?
[09:45] <bill_> I only have xubuntu OS.
[09:45] <bill_> windows is in VMware guest maching
[09:46] <diogenes_>  /dev/sdc seems like a removable drive to me.
[09:47] <bill_> the /dev/sdc in my PC is connected to SATA port
[09:49] <diogenes_> is it IDE/AHCI, what fs and how old it is?
[09:50] <bill_> the /dev/sdc is new relatively , I bought it within this year
[09:50] <bill_> bios's SATA is set as AHCI
[09:51] <bill_> by the way is Toshiba 2T, chipper one from taobao site
[09:53] <diogenes_> and filesystem?
[09:54] <bill_> it is ext4
[09:55] <bill_> When I copy a big file or folder, the process of it take too long time to be finished
[09:56] <diogenes_> install gnome-disk-utility go to SMART and self test and nitice the value of Current Pending Sector Count.
[09:57] <diogenes_> and the issue you've just stated is a known one and has a workaround.
[09:58] <bill_> @digenes sure,  I use smartctl tool to those stuff of the disk
[09:59] <bill_> but I did not see the Current Pending Sector Count
[09:59] <bill_> I am seeing it  ....
[10:00] <bill_> I got it
[10:00] <bill_>  73 197 Current_Pending_Sector  0x0032   100   100   000    Old_age   Always       -       0

[10:02] <diogenes_> ok i didn't get it in that format :)

[10:05] <diogenes_> !pastebin
[10:05] <bill_> ok I will use gnome-disk-utility
[10:08] <bill_> gnome-disk-utility cannot show me the value of Current Pending Sector Count
[10:09] <diogenes_> i guess it does the test on schedule, maybe you need a reboot.
[10:11] <bill_> the gome-disk-utility have changed completely, really different the one several year ago
[10:11] <bill_> I must use /usr/bin/gnome-disks to do that
[10:15] <bill_> @diogenes I have reboot my PC serveral times and then tested with hdparm --directiro -t /dev/sdc these day
[10:17] <diogenes_> the fact that it doesn't show  the value of Current Pending Sector Count is a question mark.
[10:19] <diogenes_> on my both drives online and offline it shows 0 sectors.
[10:21] <bill_> no question mark and no red text
[10:21] <bill_> ok will see the info of my another disk
[10:23] <diogenes_> i mean a question mark in the way that i wonder why it doesn't show it.
[10:28] <bill_> @diaogenes I cannot understand u
[10:31] <diogenes_> bill_, check this out: https://i.imgur.com/KZNDyKF.png
[10:31] <diogenes_> now show us a screenshot of yours.
[10:38] <bill_> I never used the imgur.com I am register and logining  it
[10:39] <diogenes_> bill_, nooo
[10:39] <diogenes_> don't register anything just use xfce4-screenshooter and host to imgur.
[10:47] <bill_> ok I pasted to here: https://imgur.com/5rcIHHf
[10:50] <diogenes_> bill_, ok now click on that gear icon and pick SMART Data & Self Test like in this screenshot: https://i.imgur.com/M5XGBbJ.png
[10:50] <diogenes_> and pastebin those tests.
[10:51] <bill_> I know pastebin
[10:51] <diogenes_> and your drive is LVM2
[10:52] <diogenes_> and LVM is a thing i've never had any experience with so i don't know how it might affect the performance, i suppose it might affect the performance.
[10:55] <bill_> ya I did put the whole disk to lvm2 but did not partitioned it.
[10:56] <bill_> Somebody's say I will lose something..., if I do so.
[10:57] <bill_> thank I will find time to backup data in and partition it and then put ists partions to lvm2
[11:00] <bill_> ok I thinking to buy new disk and replace it lively (lmv2 support that)
[19:09] <CarlenWhite> Getting freeze-ups but journalctl nor /var/crash show anything wrong.
[19:10] <CarlenWhite> When I tried to sysreq out, it appeared in the journalctl. So I'm a bit lost on what I can do or provided.
[19:10] <CarlenWhite> Provide, rather.
[19:11] <Alabalistic> dmesg
[19:11] <Alabalistic> did you try
[19:17] <CarlenWhite> Checking /var/log/dmesg.0 shows information 8 seconds after boot.
[19:17] <CarlenWhite> Same for the latest
[19:19] <CarlenWhite> But the crash happened long after 8 seconds.
[19:19] <CarlenWhite> Or freeze rather.
[19:20] <CarlenWhite> I'm suspecting AMD weirdness since I've had similar issues on my laptop, but it'd log whenever it hit a freeze.
