Package: pm-utils
Version: 1.1.2.4-1
Severity: normal
/usr/lib/pm-utils/sleep.d/00clear hangs because chvt 63 does not
complete.
X is not running. A pygame application is running on a frame buffer
console. This is on an OLPC XO running debxo. pygame uses SDL. The
pygame application ran pm-suspend. The system did not suspend. Process
tree shows chvt has not completed.
An strace of a manual chvt 63 shows ...
open("/dev/tty0", O_RDWR) = 3
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon
-echo ...}) = 0
ioctl(3, KDGKBTYPE, 0xbfda8a63) = 0
ioctl(3, VIDIOC_G_COMP or VT_ACTIVATE, 0x3f) = 0
ioctl(3, VIDIOC_S_COMP or VT_WAITACTIVE
At which point chvt hangs. The pygame image is still on screen. chvt
is interruptible with Control/C.
This bug might be more appropriate for kbd package, not sure.
This bug might be a failure of SDL to release the VT on demand, not sure
if there is such a demand.
I'm logging it first against pm-utils, since unless otherwise
discovered, chvt is not a reliable method to use to enter a text mode.
