I'm just about to reboot, so, before I forget the details, here's my log file, sufficient for the next person to follow (including myself) in the future: I had to re-install Firefox to prove that the desktop was crashing: $ sudo yum install firefox ==> firefox.x86_64 0:17.0.5-1.el6.centos I cleared the ~/.xsession-errors file so that I could start fresh: $ mv ~/.xsession-errors /tmp/xsession_before I rebooted so as to start a fresh xsession: $ sudo reboot I ran Firefox until the Desktop crashes again: $ firefox (it didn't take long for the Desktop to crash) I logged back into the Desktop and compared the xsession logs: $ cp ~/.xsession-errors /tmp/xsession_after $ diff /tmp/xsession_before /tmp/xsession_after Found lots of stuff, for example: ==> Window manager warning: Fatal IO error 11 (Resource temporarily unavailable) ==> nautilus: Fatal IO error 11 (Resource temporarily unavailable) on X server :0. etc. So, it's now time to update the graphics card driver. Identify your kernel: $ uname -r ==> 2.6.32-358.2.1.el6.x86_64 Identify your graphics card: $ /sbin/lspci -nn | grep VGA ==> 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GT216 [Quadro FX 880M] [10de:0a3c] (rev a2) Identify the installed version of Nvidia drivers: $ $ sudo updatedb; locate libvdpau_nvidia.so ==> /usr/lib/vdpau/libvdpau_nvidia.so.304.37 ==> /usr/lib64/vdpau/libvdpau_nvidia.so.304.37 Go to Nvidia support: http://www.nvidia.com/page/support.html Press on "Download Drivers" (that brings you to): http://www.nvidia.com/Download/.aspx?lang=en-us Enter the following information: - Product Type: Quadro - Product Series: Quadro FX Series (Notebooks) <== important to get right! - Product: Quadro FX 880M - Operating System: Linux 64-bit - Download Type: Linux Long Lived Driver - Language: English (US) Press the "Search" button (that brings you to): ==> http://www.nvidia.com/object/linux-display-amd64-310.44-driver.html - Version: 310.44 - Release Date: 2013.04.02 - Operating System: Linux 64-bit - Language: English (U.S.) - File Size: 65.2 MB Press the "Download" button (save the file but don't install it). Compare the Nvidia version with the version at the El Repo repository: http://elrepo.org/tiki/Driver+Versions Search for "nvidia" to find the latest version, which is: - Kmod Package: nvidia - ElRepo Kmod Version: 310.44 Since the El Repo version is up to date, let's use it: Enable the El Repo repository (if not already installed): $ sudo rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org $ sudo rpm -Uvh http://elrepo.org/elrepo-release-6-4.el6.elrepo.noarch.rpm Note: Skip this step if El Repo is already enabled. Install that latest version from the El Repo repository (do not use ATrpms!): $ sudo yum --enablerepo elrepo install kmod-nvidia $ sudo yum --disablerepo=\* --enablerepo=elrepo install nvidia-x11-drv-32bit ==> Updated: kmod-nvidia.x86_64 0:310.44-1.el6.elrepo ==> Dependency Updated: nvidia-x11-drv.x86_64 0:310.44-1.el6.elrepo ==> Dependency Updated: nvidia-x11-drv-32bit.x86_64 0:310.44-1.el6.elrepo Or, if you want the absolute latest in the El Repo testing repository: $ sudo yum --enablerepo elrepo-testing install kmod-nvidia $ sudo yum --disablerepo=\* --enablerepo=elrepo-testing install nvidia-x11-drv-32bit Test if you have installed the desired driver: $ $ sudo updatedb; locate libvdpau_nvidia.so ==> /usr/lib/vdpau/libvdpau_nvidia.so.310.44 ==> /usr/lib64/vdpau/libvdpau_nvidia.so.310.44 Reboot. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
