[Bug 294972] Re: MASTER: xorg high cpu usage, general system sluggishness
I've upgraded ubuntu on my laptop from 12.04 to 12.10. After that i noticed this bug several times. Ocasionaly Cpu usage of process /usr/bin/X ... reaches 20% level or more and all the system dehaves sluggishly. I 've created Xorg config manualy using $sudo Xorg -configure. I haven't noticed any wrong XOrg behaviour since that... so, manual configure seems helpful. Furthermore there are some options on the Card section you can play with.

Using 10.10 here. I noticed this problem, and my only solution is to do sudo service gdm restart I tried killing all my apps, deluged/Miro I tried setting compiz/metacity/kwin I tried using my nvidia settings to enable/disable the TV twinview (I use the TV to watch movies using SMplayer fullscreen) It doesn't touch the Xorg CPU usage. After a gdm restart, I get typically 5% cpu - right now watching a movie and working here on my LCD screen I'm seeing it rising slightly after ten minutes to about 7.5 and 8.5% - time seems to have more effect than anything else regardless of what I do. This is also unrelated to my browser (right now I'm using Chromium browser, but the same effect applies to a fresh Xorg session using only Midori or Epiphany). However totally convinced I have been, I disabled digital screenlet clock from the TV monitor - the only screenlet running - and it appears to have settled at less than 6% over the last two hours. How does a screenlet affect the X session? Why not all the time? Does anybody really understand this stuff?

Hello, as everybody here I suffer from high cpu usage due to xorg. I must say, that I tried to follow the troubleshooting guide in ubuntu wiki, but I cannot really understand how it can help me. I print the things, they suggest to print, and what...? Here is the diagnostic of my problem. I have fresh installation of Ubuntu 9.10 on Dell E6400 laptop. I have Nvidia graphic card with the newest driver 185.18.36. As many of the posts here, I start to have high cpu usage after 2-3 hours working. Then even a change of the desktop is taking 5+ sec and the fan is going crazy, everything is way to slow for a 2 core processor, 4GB or RAM and 40% usage of the HDD. I kill all the x-application which seems to take a lot of the cpu (firefox, terminal, skype) however nothing changes. Neither the system goes back to its normal speed after restart (I need to wait several hours to get it back to normal). I made all the diagnostics to check if it is not a hardware problem - apparently it is not. I added in xorg.con the options suggested by Bjiorn - no effect. I do not have compiz. I do not know to what my problems are connected. I have them since 5 months. Unfortunately I may move away from ubuntu... Any comments/suggestions are welcome. I want to say that i surfed a lot to find a solution for my problem, but no way. I could not find any strange message in the log files of xorg, none infinite loop, nothing... I would be happy if at least somebody suggests how to track the problem.

[Bug 294972] Re: MASTER: xorg high cpu usage, general system sluggishness
ubuntu 8.10 with nvidia 8400gs graphic card with two screens and xinerama(no randr extension). 1)i upgraded to 180 drivers 2)added this lines in xorg Option PixmapCacheSize 100 Option AllowSHMPixmaps 0 3)Run this after X has started: # nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1 4)added option MigrationHeuristics greedy in xorg.conf Now firefox is much more responsive, but while using google maps or simple resizing gnome-terminal Xorg eats cpu around 50-100%. i attached oprofile report. I think the battlecneck is somewhere in nvidia drivers, maybe in interface linux kernel(vmlinux) - nvidia userspace(nvidia_drv.so), which eats most cpu cycles. ** Attachment added: oprofile http://launchpadlibrarian.net/25342240/oprofile -- MASTER: xorg high cpu usage, general system sluggishness https://bugs.launchpad.net/bugs/294972 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 294972] Re: MASTER: xorg high cpu usage, general system sluggishness
Hm, sorry for intruding with my xorg on NetBSD/i386 5.0_RC3, on a Lenovo T60 with ATI X1400 graphics. But ... I was seeing the same symptoms in my setup -- Xorg using inordinate amounts of CPU time. I had an older XFree86 install with the vesa driver to verify with, where the problem did not occur, even though the application mix (xterms, firefox 3) was the same. In my case, I found a workaround for the high CPU load problem: force the radeonhd driver to use the older XAA acceleration method instead of the newer EXA method: Section Device Driver radeonhd Option AccelMethod XAA EndSection I suspect the same would help the radeon driver as well. I'm sorry, but I don't know more about the underlying reason. Hoping this might steer some folks in the right direction. -- MASTER: xorg high cpu usage, general system sluggishness https://bugs.launchpad.net/bugs/294972 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 294972] Re: MASTER: xorg high cpu usage, general system sluggishness
Bryce, it would be nice, if you could point us how to find out causes of problems. In my case situation is like this: any normal redrawing (not involving xv overlay) means that X CPU consumption goes up. It doesn't matter, if Firefox, Opera, gnome-terminal or OpenOffice want to redraw something or I just move to another virtual desktop, in all cases the desktop goes unresponsive for a while and X takes every CPU cycle it can. It's biggest pain in OpenOffice, which can't normally scroll due to this behaviour, but it's inconvenient in other programs too. Is there some way find out what X is trying to do? -- MASTER: xorg high cpu usage, general system sluggishness https://bugs.launchpad.net/bugs/294972 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 294972] Re: MASTER: xorg high cpu usage, general system sluggishness
I hate to just be another me too but I'm running Intrepid. Every few days I have to reset this box from the power switch. The culprit in every case is that Xorg has completely frozen and the box is totally unresponsive... sometimes I can move the mouse but all Keyboard escapes are non-functional. I can watch the problem beginning to occur because I keep the CPU usage panel applet running. When doing nothing that CPU usage should be fairly close to zero but after a few days it gradually climbs to around 50% and then continues to climb. The top two processes every time are Xorg and vino-server. If I catch the problem in time, killing vino-server immediately cleans up the problem with Xorg and all is well. I DO have Compiz enabled, nothing too dramatic (fairly standard settings) with the open ATI drivers (not using fglrx) with my X800 All in Wonder. The problem is definitely related to Xorg but I believe the culprit is vino-server. -- MASTER: xorg high cpu usage, general system sluggishness https://bugs.launchpad.net/bugs/294972 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 294972] Re: MASTER: xorg high cpu usage, general system sluggishness
As you say it might not be linked to Xorg. But the problem was so painfull for us and after weeks of unsuccesful trials to find out its origin, we have decided to revert to Ubuntu 8.04 and this has completly solved our issue. Our server is now running smoothly, what a pleasure ! -- MASTER: xorg high cpu usage, general system sluggishness https://bugs.launchpad.net/bugs/294972 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
