Tim Chen, as per http://h20565.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=6943835&swLangOid=8&swEnvOid=4158 an update to your computer's buggy and outdated BIOS is available (1.30). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-1.30 ** Description changed: - In https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1240940, several - users report rtl8723be still have problem on recent version of Ubuntu , - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1240940/comments/82 - suggested open a new bug, + My WiFi has an issue. - the utopic LTS enablement stack (HWE), including 3.16 kernel. uname -a looked like this: - Linux buchanan-probook-455 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux - - Also, with utopic kernel and module, some user report adding ips=N and fwlps=N does not help. - --- + --- ApportVersion: 2.14.1-0ubuntu3.7 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC1: u 1785 F.... pulseaudio - /dev/snd/controlC0: u 1785 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC1: u 1785 F.... pulseaudio + /dev/snd/controlC0: u 1785 F.... pulseaudio DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=c2a5715c-c92c-47fa-9aa2-c6f6e03f21bf InstallationDate: Installed on 2015-06-09 (0 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) MachineType: Hewlett-Packard HP 455 G2 Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-30-generic root=UUID=97d2645a-a2be-49ec-b1bd-37c43ab4eeb1 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.16.0-30.40~14.04.1-generic 3.16.7-ckt3 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
