While the data collection above is going on... here is a recap of the previous X session (2020-07-05 thru 2020-08-10)
* Restarted X server with XFCE. * Apps used almost all the time: mostly Firefox, MATE terminal * Apps used sometimes: VLC, "xpra attach", geeqie * Apps used rarely: libreoffice I have collected a number of "ps fuxa" outputs which I distilled below only to show the VSIZE and RSS for that Xorg xserver process: ~~~ 2020-07-05 22:39:08 907048 88500 2020-07-05 22:42:24 950740 129288 libreoffice 2020-07-08 15:13:30 1199296 250108 libreoffice 2020-07-11 21:55:10 1227060 277484 libreoffice (vlc started after this) 2020-07-13 12:16:53 1217636 271656 vlc 2020-07-15 12:40:25 1234728 293524 vlc 2020-07-17 23:24:01 1906196 940544 vlc(163655) (2GB mem usage, terminated) 2020-07-19 20:19:16 2217016 1046988 vlc(357305) 2020-07-20 13:09:06 2235980 1071448 vlc 2020-07-22 13:18:05 2296896 819008 vlc 2020-07-22 13:36:04 2292208 862640 2020-07-22 13:36:47 2259436 860288 2020-07-22 14:07:13 2201380 923184 2020-07-30 00:53:51 2257172 1153128 2020-08-02 20:57:49 2213628 1178836 2020-08-03 11:54:58 2250960 1182832 vlc(793990) 2020-08-08 10:35:37 2493120 1526196 ~~~ Note: I also filed another bug originally against VLC--because where you saw the large memory usage above, VLC also showed memory explosion. https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1888558 Since that time it was re-attributed to MESA driver. Looking at the pattern above, there is a strong likelihood that VLC/MESA is one of the culprits for large X memory consumption. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1884850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
