Try to downgrade some recent drivers or the X if you only started having this problem recently. If the X is stuck, you can try Alt-SysRq-r before switching to virtual console (it makes keyboard input raw, instead of going through Xorg). > I found this article: > https://wiki.archlinux.org/index.php/Keyboard_shortcuts > > And I put " kernel.sysrq = 1" > > > into /etc/sysctl.d/99-sysctl.conf Note the following commands I've tried: # sysctl kernel.sysrq = 1 ; echo $? kernel.sysrq = 1 sysctl: malformed setting "=" sysctl: cannot stat /proc/sys/1: No such file or directory 253 # sysctl 'kernel.sysrq = 1' ; echo $? sysctl: cannot stat /proc/sys/kernel/sysrq : No such file or directory 255 # sudo sysctl kernel.sysrq=1 ; echo $? kernel.sysrq = 1 0 I didn't know, but it seems there can't be any spaces. As it's the same program processing /etc/sysctl.d/99-sysctl.conf, there can't be any spaces there either. It's like variables in bash I suppose: spacing makes all the difference. > I've rebooted, and I still can't get it to work.
