The VT switch requires the cooperation of the X server, but it's blocked waiting for input in gdb (because it involves sending SIGUSR1 to X). And even handle SIGUSR1 nostop won't be enough, since once you've crashed X you'll want to get back to gdb, which involves a new VT switch with X blocked waiting for input in gdb.
