Public bug reported: Binary package hint: xorg
I have Gateway M62 laptop (Intel Core 2 Duo T5750; ATI Mobility Radeon HD 2600 [RV630/M76], 4GB RAM). I upgraded from Jaunty about a week ago. My system is constantly updated, in sync with changes in the Karmic repository. Xorg performance has been terrible. With fglrx (installed from the Ubuntu repos), Xorg sometimes pins down one core completely, for prolonged periods (95-100% CPU usage). The problem may or may not go away on reboot (unpredictable, indeterminate). When it is "behaving", the system is snappy and usable. I purged my fglrx (and all config files and all related packages) and reinstalled afresh from the Karmic repos. No change. I do not run compositing on my desktop. I have a dual screen configuration (with an external 19 inch Acer monitor, see attached Xorg.conf files). Now, fglrx is actually the good one this time round (surprisingly). When I _purged_ fglrx, I decided to run on the open source drivers for a while. Performance with the open source drivers is not merely bad - its goddamn awful. An example - It is impossible to run Netbeans or Eclipse and get any work done. Screen painting is so slow that there is a lag of up to 5 seconds between a click and a response. Dragging a small window (like Gnome terminal) is an ulcer inducing experience. This system is not performance, memory or load challenged. Booting without an xorg.conf with the aim of running a non mirrored dual screen setup is presently not an option. Other problems (not directly related to xorg) include the inability of gnome-display-properties and grandr to correctly set up the screen resolutions of both screens. These should (and probably, will) be reported as separate bugs, but I have mentioned them here for context. I have attached: (1) A screenshot of gnome-terminal (top) showing the load (2) My present xorg.conf, generated by amdcccle (3) The xorg.conf used with the -radeon driver) (4) An Xorg.conf that previously worked well with fglrx (I keep /etc under version control), under Jaunty (5) An Xorg.conf that previously worked well with the open source driver, under Jaunty ProblemType: Bug Architecture: amd64 Date: Fri Oct 2 11:05:10 2009 DistroRelease: Ubuntu 9.10 NonfreeKernelModules: fglrx Package: xserver-xorg 1:7.4+3ubuntu5 ProcEnviron: SHELL=/bin/bash PATH=(custom, user) LANG=en_US.UTF-8 ProcVersionSignature: Ubuntu 2.6.31-11.36-generic RelatedPackageVersions: xserver-xorg 1:7.4+3ubuntu5 libgl1-mesa-glx 7.6.0~git20090817.7c422387-0ubuntu6 libdrm2 2.4.13-1ubuntu1 xserver-xorg-video-intel 2:2.8.1-1ubuntu2 xserver-xorg-video-ati 1:6.12.99+git20090825.fc74e119-0ubuntu2 SourcePackage: xorg Uname: Linux 2.6.31-11-generic x86_64 system: distro: Ubuntu architecture: x86_64kernel: 2.6.31-11-generic ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug -- High Xorg CPU usage (95-99%): Karmic x86-64, fglrx, ATI Mobility Radeon HD 2600 https://bugs.launchpad.net/bugs/440448 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ 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
