Public bug reported: I noticed when i restarted my laptop (HP 630 after installing the latest stable linux kernel (linux-image-13.110.13-generic:amd64 13.11.0-13.20), there was no sound, i could not connect to the internet via either cable or wireless and the graphics was slow. On further inspection i found out no network manager displayed "network devices available" and there was a dummy output in sound settings.
After searching the internet i came across this link ---> http://askubuntu.com/questions/294016/no-sound-in-ubuntu-13-04-only-dummy-output-device-listed After following the instruction and choosing an earlier version of kernel (3.11.0-12-generic), all the issues were resolved. I have ubuntu 13.10 installed. Below is the comment that helped. Hope this is helpful in some way to deal with the issue with the latest kernel. "I also had it - Does sound work before reboot after one update? If yes it is probably the same. It's bug related to kernel 3.8.0-18. Run uname -r to check your version of Kernel. If it is 3.8.0-18-generic - try next steps Reboot and in GRUB select Advanced options Chose Ubuntu with Kernel ... (Any before -18) Also you can subscribe this bug at Launchpad, I hope they will fix it soon" ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: saucy ** Attachment added: "lspci-vnvn.log" https://bugs.launchpad.net/bugs/1250363/+attachment/3906157/+files/lspci-vnvn.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1250363 Title: Kernel causes HDMI Audio, network cards to stop working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1250363/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
