Frozen or locked screen?

[Pandurangan R S]

Hi,

My screen looks to be frozen. screen -x (or screen -d) also gets stuck.

I recently saw a thread which talks about accidentally locking the
screen and thinking it is frozen.
Is the case with my screen now? If so, how can i unlock it?


If I strace the screen process, I observe the following. Any hints?

Process 15342 attached - interrupt to quit
pause()                                 = ? ERESTARTNOHAND (To be restarted)
--- SIGALRM (Alarm clock) @ 0 (0) ---
sigreturn()                             = ? (mask now [])
alarm(0)                                = 0
kill(6866, SIG_0)                       = 0
rt_sigaction(SIGALRM, {0x806a540, [], 0}, {0x806a540, [], 0}, 8) = 0
alarm(15)                               = 0
pause()                                 = ? ERESTARTNOHAND (To be restarted)
--- SIGALRM (Alarm clock) @ 0 (0) ---
sigreturn()                             = ? (mask now [])
alarm(0)                                = 0
kill(6866, SIG_0)                       = 0
rt_sigaction(SIGALRM, {0x806a540, [], 0}, {0x806a540, [], 0}, 8) = 0
alarm(15)                               = 0
pause(
