[Desktop-packages] [Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing) when LibreOffice is running
One point of observation. Since this time, I am switching to Debian 10 for daily work because I couldn't bear X11 memory growth. The package information for my Debian install: * xserver-xorg version 1:7.7+19 * xserver-xorg-video-intel version 2:2.99.917+git20180925-2 * linux-image-4.19.0-17-amd64 version 4.19.194-3 (stock kernel, unmodified) This does not produce the same kind of unabated memory growth. Please let me know if anything can be done to help diagnose the problem. I have not gotten rid of the Ubuntu 20.04 install yet, though I had switched to xfce for daily work, before eventually I installed Debian 10. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) when LibreOffice is running Status in libreoffice package in Ubuntu: Confirmed Bug description: Description: Xorg server uses unacceptably large amounts of memory (and keep growing) Ever since I upgraded to Ubuntu 20.04 (with fresh install) on my laptop (Lenovo T450s, Intel Core i5-5200U, Intel HD5500 graphics), I have been troubled by the way Xorg process uses memory.

Dave, I am suspecting a bug with the X hardware driver. Can you please describe the machine you are using. Plus produce the output of "lspci" and "lsmod"?

Here is a fuller analysis (see next attachment, Xfce- session-20200922-analysis.html). I started LibreOffice on 9/22 nearly exclusively on a new Xfce session. (Except for the MATE terminal app, again). I edited a few documents, as indicated in the analysis. Every time without exception, the X pixmap memory usage grew. My previous attachment (graph) showed that the X memory usage eventually exploded after an extended period of time the LO Writer app was open--nearly a month. This time, I did not do that. But I managed to show in the graph that almost every document edit leads to a significant increase in the X pixmap memory usage (5 MB, 10 MB, and even 20 MB just looking at the graph). The problem is, once the LibreOffice is closed, the X pixmap memory usage won't shrink anymore. I do have the xrestop snapshots of the LibreOffice usage but haven't had chance to process the data to graph it. Ask me if that is desired. But I will send the script that polls the memory usage as a second attachment in case that is useful for others to monitor the memory growth. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) when LibreOffice is running Status in libreoffice package in Ubuntu: New Bug description: Description: Xorg server uses unacceptably large amounts of memory (and keep growing) Ever since I upgraded to Ubuntu 20.04 (with fresh install) on my laptop (Lenovo T450s, Intel Core i5-5200U, Intel HD5500 graphics), I have been troubled by the way Xorg process uses memory.

[Desktop-packages] [Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
Update 20200922 I have tested LibreOffice for a while. It did cause Xorg memory explosion again as explained below. I am excerpting my own personal notes here, please bear with the rough form of it. The graph that I will attach next will show the point. I started using a LibreOFfice program at 2020-09-06; this was a relaunch after the last comment. At timestamp = 20200921T2330, I checked Xorg memory usage tonight after leaving LibreOffice open for over 11 days: Xorg RSS became swollen to over 1 GB! xorg RSS ... 1182768 kiB The "free" status was terrible: totalusedfree shared buff/cache available Mem: 12144888 9761024 596696 710552 1787168 1353420 Swap: 1808384 1477752 330632 Three major users of Xorg memory: LibreOffice Writer ( PID:1760594 ): pixmap bytes : 334753205 1 - xfwm4 ( PID:1477670 ): pixmap bytes : 141633828 Mozilla Firefox ( PID:1816946 ): pixmap bytes : 44090522 The total of all three is ~520 MB. LibreOffice alone is eating up over 334 MB of RAM! NOTE: I did not use LibreOffice every day on this machine. But I left that program open since it was opened on Sept 6. I used the LO Writer occasionally to make notes now and then. Now I am closing the LibreOffice program, see what happened. Before LibreOffice doc was closed, the mem usage status was: LibreOffice pixmap bytes usage dropped to 286360981 (pixmap bytes) xfwm4 131834529 (pixmap bytes) firefox 44090522 (pixmap bytes) xorg RSS 1203568 kiB => misleading, too much dumped to swap! Let's close LibreOffice; after closing (time marker = 20200922T0006) the usage: xfwm4 98517409 firefox 44090522 xorg RSS 1192256 kiB A few observations: * As you can see above, xorg RSS was NOT significantly reduced even after I closed the LibreOffice. That was not the case with Firefox or with Xpra; the memory usage dropped as soon as I closed those programs. * I also remember from my past observations that *when this Xorg memory explosion occurred*, the RSS of the xorg server is way higher than the (rough) sum total of the pixmap memory consumption reported by xrestop. My fuzzy memory has it at about a factor of 4: RSS(Xorg) ~ 4x sum(pixmap bytes reported by xrestop) The example above did not quite support that though, but still, it is a factor of more than two! * I also looked at smaps: (ref: smaps-1600747980-20200922T001300.txt). That file indicates the largest memory occupied is in the heap: $ grep -e '^[0-9a-f]' -e 'Dirty' smaps-1600747980-20200922T001300.txt ... 55aa90005000-55aad31ae000 rw-p 00:00 0 [heap] Shared_Dirty: 0 kB Private_Dirty: 1078916 kB ... Now I closed Firefox as well: (after closure, timestamp: 20200922T0034) xfwm4 61755763 xorg RSS 1149028 kiB Again, it looks like firefox X pixmap memory was freed ok (xorg RSS dropped by ~50 MB), but not much lower. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) Status in xorg-server package in Ubuntu: New Bug description: Description: Xorg server uses unacceptably large amounts of memory (and keep growing) Ever since I upgraded to Ubuntu 20.04 (with fresh install) on my laptop (Lenovo T450s, Intel Core i5-5200U, Intel HD5500 graphics), I have been troubled by the way Xorg process uses memory.

[Desktop-packages] [Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
I have tested two applications so far... 1) firefox + MATE terminal 2) xpra + MATE terminal I'm sorry I can't not use MATE terminal because I still have to use part of the laptop for work. In either case I did not notice too significant a memory growth. Again, the memory usage numbers mentioned below are the "RSS" reported by "ps". In the case of Firefox: memory usage is approximately ~130MB (I belive this was right after Firefox was started and fully running) to over ~150 MB after 7-8 days of use. But I tried this: I closed Firefox, the memory usage dropped to below 90 MB. So at least I know that Firefox X memory seems to be released. In the case of running xpra: before xpra is running (right after X server restart), X server memory usage is about 80 MB, and it goes up to ~120-130 MB after 3 days. It dropped back to 96MB. I don't fully know why this yet. Maybe there is some leak, but I also want to note that xfwm4 is uses significant amount of X memory. In this case and previous case, I also note that the xrestop reports increasing memory usage of "xfwm4" over time. Initially when the Xserver just restarted, xfwm4 uses ~30 MB of X memory. It goes up and down, seemingly dependent on how many windows are opened. So, no conclusion yet on that end. Note: I am running gnucash (or gnucash and firefox) on the XPRA server. I tend to think that the stuff I run under XPRA will to a good degree not affect the xserver being diagnosed except by the number of windows it displays. I have currently been running libreoffice on the existing session (xpra+MateTerm) just to find out how things are. I have personally suspected libreoffice and/or vlc. So far, libreoffice seems to exhibit this apparent behavior: when I am actively using it, the X server RSS goes up. But when I leave that libreoffice window alone, the RSS does not increase. I'll have to re-test this by itself and report back. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) Status in xorg-server package in Ubuntu: New Bug description: Description: Xorg server uses unacceptably large amounts of memory (and keep growing) Ever since I upgraded to Ubuntu 20.04 (with fresh install) on my laptop (Lenovo T450s, Intel Core i5-5200U, Intel HD5500 graphics), I have been troubled by the way Xorg process uses memory.

[Desktop-packages] [Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
Brief comment. Have restarted X server 3 days ago to run pretty much just Firefox + MATE terminal. Will let you know later how this goes. So far the X server memory usage (RSS) is about 125-130MB. Which is high, but not super terrible. Usually it takes a few more days before the usage swells. Another comment, xfwm4 is using quite a bit of X pixmap memory (50-54 MB as reported by xrestop). I have 4 desktops, and the laptop display ix FHD 1920x1080. I wonder if window image caching is what causing this. When it started it measured already at 30MB. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) Status in xorg-server package in Ubuntu: Incomplete Bug description: Description: Xorg server uses unacceptably large amounts of memory (and keep growing) Ever since I upgraded to Ubuntu 20.04 (with fresh install) on my laptop (Lenovo T450s, Intel Core i5-5200U, Intel HD5500 graphics), I have been troubled by the way Xorg process uses memory.

[Desktop-packages] [Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
Hi Daniel, responding to your comment: In my years of using Linux desktop (in particular, XFCE), I have never experienced memory explosion caused by Xorg server like what I described in this bug report. Please allow me to be a bit candid here. It seems like the newer versions of desktop software (which could mean one or more of these: Xorg, firefox, Libre Office, XFCE and/or MATE, ...) leads to significant bloat in memory usage. This is to the point that a very capable laptop (with >= 8 GB of RAM) would perform poorly because of memory thrashing today even when our usage pattern is not changed over the years (at least I feel so). I'll back this up below. I still have a desktop computer running Debian 8 and XFCE.

[Desktop-packages] [Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
Thanks. I am testing XFCE desktop for now. A brief comment on XFCE experience. The starting size of Xorg process under XFCE is ~100-130 MB, but after 10 days of usage with mostly Firefox & terminal windows (multiple windows for each app, and sometimes pdf viewer [atril]) it grew to 270-300 MB. I have some data collected by xrestop, ps, if you want it. Let me know what kind of data would help. In a prior session where I was still using LibreOFfice (again, with multiple windows, but nothing is a huge document or complicated doc with lots of graphics), the memory usage grew to over 800 MB usage. And xrestop indicated libreoffice was consuming nearly 200 MB of pixmap memory just before I closed it! Any direction to help narrow down the source of large memory consumption would be appreciated.

[Desktop-packages] [Bug 953440] Re: Screen corruption observed randomly
Thanks for the reply. I launched the live CD version of the daily build on the machine. The display was changed to a different monitor with ordinary 1280x1024 resolution. Sorry, it is not practical for me to repeat the old setup and rerun the test. I see that the nouveau driver is indeed loaded on that machine, so this is an opportunity to try out the new version of the OS. I am yet to check whether the screen corruption would occur in this setting. But I am frustrated by the flashy animations of windows etc, which I suspect is due to compiz (I can see compiz process using lots of CPU). How do I disable this? Sorry this is OOT, but if you (@Christopher) can help, I may be able to test out some more without the flashy compiz stuff.

On random occasion, usually after unlocking a screen saver, the screen will look corrupt. Symptoms: 1) desktop background is always corrupted 2) Letters from some fonts would become garbled. To work around (1), I could restart nautilus. But for the other symptom, I don't know. Background: I originally installed this when I had a different external display (and I was using proprietary nvidia driver included in Ubuntu 10.04 LTS). The original resolution was 1600x1024. But with the higher resolution, the proprietary driver was not adequate (it would not even show anything beyond 1280x1024, I believe?), so I had to give it up and use the (apparently unstable) nouveau driver. Is this bug resolved somewhere else? If so I would like to know which version. Feel free to ask me more question.
