Debdiff from acpi-support .138 to .138-ubuntu1 ** Description changed:
+ SRU Justificaiton + ----------------- - The acpi-support scripts use 'ps' and 'who' output to determine the current active X display and X user (in getXconsole and getXuser). Currently, LightDM does not write to utmp so 'who' does not output the correct information breaking getXconsole and getXuser. + Impact: + + This bug impacts all Oneiric systems which use LightDM and are affected + by lp870297 (Lightdm logins not being logged in wtmp). + + In Oneiric, acpi-support depends on wtmp entries to determine the active + console with getXconsole and getXuser. Since LightDM doesn't write to + wtmp, this affects all systems that use acpi-support scripts to handle + ACPI hotkey events -- including yet to be released hardware in the + enablement/certification queue. + + Fix: + + The fix is to backport the changes made in Precise to Oneiric. This + includes implementing getXuser and getXconsole with ConsoleKit (ck-list- + sessions). + + Patch: + + This change is already in acpi-support .139: + + http://launchpadlibrarian.net/95198647/acpi- + support_0.138_0.139.diff.gz + + I've attached a debdiff that backports that change to acpi-support .139 + in Oneiric. + + Regression Potential: + + There should be very little potential for regression. In fact, this + should fix machines affected by lp87029, including OEM systems. + + ------------------------ + + The acpi-support scripts use 'ps' and 'who' output to determine the + current active X display and X user (in getXconsole and getXuser). + Currently, LightDM does not write to utmp so 'who' does not output the + correct information breaking getXconsole and getXuser. ConsoleKit properly maintains the state of the console and probably should be used instead. I've attached a patch that re-implements getXconsole and getXuser by calling ck-list-sessions. ** Patch added: "acpi-support.diff" https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/933626/+attachment/2997934/+files/acpi-support.diff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/933626 Title: acpi-support should use ck-list-sessions to determine active X display and X user To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/933626/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
