Christopher, thank you for your advice and my apologies for not following the protocol of first checking for BIOS updates.
I have now updated the BIOS. Results of "sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date" are: Version 1.80 04/18/2013 so the update has worked. Unfortunately the problem still persists as previously described. Please note the problem also manifests on my wife's Toshiba Protege Z835-ST8305 which I have also updated to the latest BIOS. Her computer is also running Ubuntu 14.04 with kernel version Ubuntu 3.13.0-30.55-generic 3.13.11.2 Thank you for your help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1338063 Title: [Toshiba Portege Z835-ST6N03] Brightness control lost after suspend screen dimmed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1338063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
