Went ahead and did some diagnosing as per the Debugging GPM wiki article. I started GPM in verbose mode and set it to log to a file. I'm posting the file as an attachment, as well as the relative event lines in the comment here.
This is what happens when the AC is unplugged: TI:23:50:41 TH:0x9fb9640 FI:gpm-brightness-xrandr.c FN:gpm_brightness_xrandr_foreach_resource,375 - resource 1 of 4 TI:23:50:41 TH:0x9fb9640 FI:gpm-brightness-xrandr.c FN:gpm_brightness_xrandr_foreach_resource,375 - resource 2 of 4 TI:23:50:41 TH:0x9fb9640 FI:gpm-brightness-xrandr.c FN:gpm_brightness_xrandr_output_set,322 - percent=100, absolute=15125 TI:23:50:41 TH:0x9fb9640 FI:gpm-brightness-xrandr.c FN:gpm_brightness_xrandr_output_set,324 <---- AC Unplugged, GPM icon locks, brightness changes stop being shown on OSD, corrupted graphic appears on screen. - hard value=7563, min=0, max=15125 TI:23:51:23 TH:0x9fb9640 FI:gpm-brightness-xrandr.c FN:gpm_brightness_xrandr_foreach_resource,375 <---- GPM Icon changes, brightness OSD appears if changed while locked, corrupted graphic disappears. - resource 3 of 4 TI:23:51:23 TH:0x9fb9640 FI:gpm-brightness-xrandr.c FN:gpm_brightness_xrandr_foreach_resource,375 - resource 4 of 4 TI:23:51:23 TH:0x9fb9640 FI:gpm-backlight.c FN:gpm_backlight_brightness_evaluate_and_set,456 - emitting brightness-changed : 100 TI:23:51:23 TH:0x9fb9640 FI:gpm-profile.c FN:ac_adaptor_changed_cb,632 - on AC TI:23:51:23 TH:0x9fb9640 FI:gpm-info.c FN:gpm_info_event_log,579 - Adding 0 to the event log The LCD backlighting changes the moment AC is unplugged and it will toggle even if AC is replugged while GPM is locked up, so HAL is operating properly, GPM seems to be what's locking for some reason. I'll do whatever I can to help out discover where the problem is. ** Attachment added: "gpm.debug.log.txt" http://launchpadlibrarian.net/18519545/gpm.debug.log.txt -- GPM Icon locks up on AC Status change https://bugs.launchpad.net/bugs/274197 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
