["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Seth Randall, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

** Tags added: bios-outdated-2.30

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  X windows resets thinkpad hotkeys when coming out of suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Steps to reproduce
  1. Enable ThinkPad hotkeys with 'echo reset > /proc/acpi/ibm/hotkey'
  2. 'cat /proc/acpi/ibm/hotkey' shows:
      status:		enabled 
      mask:		0x008dffff
      commands:	enable, disable, reset, <mask>
  2. Suspend laptop with Fn+F4
  3. Power up laptop again
  4. 'cat /proc/acpi/ibm/hotkey' shows: 
      status:		enabled
      mask:		0x0000ffbf
      commands:	enable, disable, reset, <mask>

  Enabling debugging on the thinkpad_acpi driver shows:
  [ 2532.894191] thinkpad_acpi: procfs hotkey: PID 1045: set mask to 0x008dffff
  [ 2537.807386] thinkpad_acpi: ACPI backlight control delay disabled
  [ 2537.950624] thinkpad_acpi: volume_get_status_ec: status 0x07
  [ 2538.118276] thinkpad_acpi: procfs: PID 2841: attempt to disable bluetooth
  [ 2540.151146] thinkpad_acpi: procfs hotkey: PID 1045: set mask to 0x0000ffbf

  PID 1045 in this case is:
  /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none

  An strace on 1045 shows the following:
  20:48:53.106913 [b7834424] open("/proc/acpi/ibm/hotkey", O_RDWR) = 23
  20:48:53.107000 [b7834424] fstat64(23, {st_dev=makedev(0, 3), st_ino=4026532245, st_mode=S_IFREG|0644, st_nlink=1, st_uid=0, st_gid=0, st_blksize=1024, st_blocks=0, st_size=0, st_atime=2011/11/28-20:48:53, st_mtime=2011/11/28-20:48:53, st_ctime=2011/11/28-20:48:53}) = 0

  20:48:53.107185 [b7834424] write(23, "0x8dffff\0\0", 10) = 10
  20:48:53.108141 [b7834424] close(23)    = 0
  20:48:53.108220 [b7834424] munmap(0xb7823000, 4096) = 0

  and

  20:49:13.538004 [b7834424] open("/proc/acpi/ibm/hotkey", O_RDWR) = 24
  20:49:13.538135 [b7834424] fstat64(24, {st_dev=makedev(0, 3), st_ino=4026532245, st_mode=S_IFREG|0644, st_nlink=1, st_uid=0, st_gid=0, st_blksize=1024, st_blocks=0, st_size=0, st_atime=2011/11/28-20:49:13, st_mtime=2011/11/28-20:49:13, st_ctime=2011/11/28-20:49:13}) = 0
  20:49:13.538311 [b7834424] mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb4b8f000
  20:49:13.538410 [b7834424] read(24, "status:\t\tenabled\nmask:\t\t0x008dffff\ncommands:\tenable, disable, reset, <mask>\n", 1024) = 76
  20:49:13.538580 [b7834424] _llseek(24, -41, [35], SEEK_CUR) = 0
  20:49:13.538689 [b7834424] write(24, "0xffbf\0", 7) = 7
  20:49:13.540414 [b7834424] close(24)    = 0

  Instruction pointer b7834424 is listed in /proc/1045/maps as [vdso]. I'm not sure how to determine what that is.
