hi everyone,
i currently use Slackware 13.1 64 bit.
when i want to get back to console after use "startx" command, my monitor suddenly off and would not turn on until i restart my computer.
so i could never get back to console when i've started x window.
hope someone can help me...
just for info, i use ATI HIS HD 5670.

Is the monitor powering off or do you mean only a black screen? Is the power indicator on or off?

If the screen is only black but you have power, can you toggle to alternate consoles by pressing Alt-F2, Alt-F3, Alt-F4, etc?

If the screen is only black but you have power, try (blindly) typing xset dpms force on.

Do you use an xorg.conf file? Is there a directive Option "DPMS" "TRUE"? If yes, as a test, change that to false and try again.

Try typing the following before typing startx:

setterm -blank 0
xset s off
xset -dpms

Then type startx and then exit X. What happens?

Do you have some kind of laptop acpi scripts running that is being tricked into thinking that exiting X is the same as closing the laptop lid?
