Updated debdiff to show bug number. ** Summary changed:
- pm-utils doesn't detect uswsusp in hardy (with fix) + pm-utils doesn't detect uswsusp in hardy ** Description changed: Binary package hint: pm-utils - This prevents uswsusp from being used (except by calling s2disk - manually). The reason pm-utils doesn't use uswsusp to suspend to disk - is because /usr/lib/pm-utils/defaults doesn't look for s2disk in the - right location, preventing the script from autodetecting uswsusp's - presence properly. The fix is to modify /usr/lib/pm-utils/defaults in - the pm-utils package to add the proper path where Ubuntu installs - uswsusp's utilities: + pm-utils does not detect the presence of uswsusp (it looks for s2disk in + /usr/sbin instead of /sbin), resulting in Suspend and Hibernate using + pm-utils's default method. For some users (those whose systems cannot + suspend/hibernate without uswsusp), this means that Suspend/Hibernate is + completely broken for them. For other users, uswsusp just isn't used, + which leads to a longer hibernate/resume time. + + In the development branch, pm-utils had been upgraded to + 1.1.2.4-1ubuntu1, i.e. new release. The relevant patches that had errors + with them, i.e. 10-uswsusp-support.patch and 30-comment-defaults- + file.patch were obsoleted in 1.1.0-1. + + A debdiff fixing the patches mentioned above, and the corresponding + build log has been attached, see comments 2 and 4. + + TEST CASE: Install uswsusp, then hibernate the system. Upon resuming, + run the command "dmesg | grep swsusp". That should tell whether or not + uswsusp was used when hibernating, i.e. no output means uswsusp wasn't + used. + + Regression potential: none apparent, unless the s2disk binary gets + relocated. + + Current workaround: + Modify /usr/lib/pm-utils/defaults in the pm-utils package to add the proper path where Ubuntu installs uswsusp's utilities: # where is the s2disk binary located? Defaults to "/usr/sbin/s2disk" # (do not change unless you kow what you are doing) # # Set the path so the script autodetects s2disk in the location # Ubuntu's uswsusp package installs it. S2DISK_BIN="/sbin/s2disk" - - -Note that this is NOT duplicate of #109151, which is a problems in acpi-utils which basically isn't used in Hardy. - - -Using uswsusp was the only way I could get my MacBook Pro C2D to - hibernate. - -Until the repositories fix this, the workaround is to copy /usr/lib/pm- utils/defaults to /etc/pm/config.d/config and make the change above in /etc/pm/config.d/config ** Attachment added: "Updated debdiff that shows LP bug number" http://launchpadlibrarian.net/17241759/pm-utils_0.99.2-3ubuntu10_0.99.2-3ubuntu11.debdiff -- pm-utils doesn't detect uswsusp in hardy https://bugs.launchpad.net/bugs/246053 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
