[Ubuntu-x-swat] [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 Ubuntu-X, 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1884850/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [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 Ubuntu-X, 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1884850/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [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 Ubuntu-X, 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1884850/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [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.

[Ubuntu-x-swat] [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.

[Ubuntu-x-swat] [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.

[Ubuntu-x-swat] [Bug 953440] [NEW] Screen corruption observed randomly
Public bug reported: I am using nouveau driver to drive a ViewSonic LCD display that has HD resolution (1920x1080) on this computer. 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.

[Ubuntu-x-swat] [Bug 777956] Re: X display with Intel i915 driver occasionally goes blank after resume from suspend
Hmm... nobody responded. I found a few posting on Ubuntu Forums which might or might not be relevant: http://ubuntuforums.org/showthread.php?t=1467927 * This one says flickering about once a minute. I did not experience this. I did experience occasional flickering but not as often as once a minute. The flicker is very quick and the display goes back to normal. I was afraid if this was my hardware error; but now I suspect it is probably software-related. * The "solution" mentioned there (about disabling RANDR service) does not apply to me. Apparently it is for KDE-based Ubuntu desktop; I am using GNOME. * But there is a mention about a bug in Lucid intel driver (see post #10): "For what I've read, there's a bug on Lucid with the Intel Corporation Mobile 4 Series Chipset, and it hasn't been fixed, so we're out of luck. If anyone else knows more about this, please let us know!" No specific reference pointed out. I wonder if the bug is related to black screen problem I occasionally have. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/777956 Title: X display with Intel i915 driver occasionally goes blank after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/777956/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 777956] [NEW] X display with Intel i915 driver occasionally goes blank after resume from suspend
Public bug reported: Binary package hint: xorg I have had Ubuntu 10.04 on my laptop (see details in attachments) since September 2010. I have been using kernel modeset. This one has a hybrid Intel/ATI display. I disabled the ATI one and only used the Intel. Here is the relevant lspci output: 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) For a while this laptop suspended and resumed with no problem whatsoever. I use this laptop as a work machine that I suspend/resume often (once or twice a day if not more). Recently (for a few months) the laptop sometimes wake up with a bizzare behavior on the LCD display: it flashes a bright light then the LCD went black. Never to recover until I rebooted the laptop. Trying to suspend and resume again won't help. The result from dmesg etc came from a fresh reboot, so it might not show anything there. Once I tried to "scavenge" for debug info or other logged problems when this happened by gathering all the dmesg, /var/log/kern, /var/log/messages or /var/log/Xorg.0.log -- they did not contain anything useful AFAIK. I can attach them if you want. The difficulty is that this bug would not appear consistently. It only appears randomly and I can't tell when it would happen. I am filing this bug report just in case other Thinkpad users with intel integrated graphics also experienced similar problem (or if it has been reported elsewhere). I have a suspicion that perhaps some kernel update in the past caused this bug, since it never happened before. Another point to consider: from time to time I would use xrandr to duplicate or extend the display to external VGA projector. (`xrandr -q' is usually all I did and the magic is done). Not sure if this has to do with the problem said above.
