Public bug reported:
Binary package hint: kbd
I'm using ubuntu jaunty, and after a few sessions of the graphical
interface, the video console goes dark. ctrl-alt-F1 does not switch to
a textmode console. (a getty is listening on /dev/tty1)
i can ssh into the machine, but when i try to chvt 1 to get to the first
virtual terminal, chvt hangs.
if i strace it, it is hanging here:
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
ioctl(3, KDGKBTYPE, 0xbff34363) = -1 EINVAL (Invalid argument)
close(3) = 0
open("/dev/tty", O_RDWR) = 3
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
ioctl(3, KDGKBTYPE, 0xbff34363) = -1 EINVAL (Invalid argument)
close(3) = 0
open("/dev/tty0", O_RDWR) = 3
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 -opost -isig -icanon -echo
...}) = 0
ioctl(3, KDGKBTYPE, 0xbff34363) = 0
ioctl(3, VIDIOC_G_COMP or VT_ACTIVATE, 0x1) = 0
ioctl(3, VIDIOC_S_COMP or VT_WAITACTIVE^C <unfinished ...>
I think that chvt probably shouldn't hang if it fails to switch over;
maybe it should exit with a non-zero return code? i don't know if it's
possible to detect the difference from the ioctl.
This might be a kernel or driver or hardware bug (feel free to reassign
if you think chvt is not at fault), so here is a bunch of information
about the system in question:
