Darn. Even if I do this from a terminal while Portal is in an emulated desktop: Code: echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope hl2Pid=`pgrep hl2.exe` gdb --pid $hl2Pid &> /home/shjake/Desktop/hl2dbg.log I get the freeze. I got this in my log: Code: Attaching to process 4397 Reading symbols from /usr/bin/wine_1.3.29/bin/wine-preloader...done. 0xf778742e in __kernel_vsyscall () (gdb) Hangup detected on fd 0 Error detected on fd 0 error detected on stdin A debugging session is active.
