Where can i get the update from ? 1498310 5 markhkamp 2015-02-07 06:29:58 +0000 Kernel update: I found two links for installing a newer kernel on openSUSE. <http://kernel.opensuse.org/packages/stable> is for the command line and has some other links. <http://software.opensuse.org/download.html?project=Kernel:stable&package=kernel-default> is for Yast 1-Click Install and should be simple. NOTE: I recommend making a btrfs snapshot of your openSUSE subvolume before proceding. Then, if the newer kernel breaks something, you can boot to a live CD/DVD/USB, remove the broken openSUSE subvolume, and restore from the snapshot. Otherwise, be prepared to reinstall openSUSE if things break. Bug reproduction attempt: My computer's also running 64-bit openSUSE 13.2 with kernel 3.16.7-7-desktop, two screens and btrfs. However, I can't reproduce the issue. I tried disabling each screen and all that happened was it took a few seconds to make the changes, windows were moved around, and widgets were moved. Graphics driver info: I suspect that it has something to do with your graphics driver/card combination. My computer has a GTX 560 and is using the default open source drivers. What graphics card/driver combination is your computer running? I think that information might help the developers. Btrfs info: In case this is btrfs-related and not graphics card driver related, here's my openSUSE btrfs setup as an example of what doesn't have the crash. I installed openSUSE 13.1 to an ext4 partition, copied everything to an @suse btrfs subvolume (with more subvolumes for other distros, /home, and /home/<username>), reconfigured grub to boot to @suse, and changed @suse/etc/fstab. I have since updated to openSUSE 13.2 and everything is up-to-date. My computer's fstab mounts @suse as /, @home as /home, and the btrfs partition's root as /mnt; it also uses tmpfs for /tmp and /var/tmp.
