 |
|
Hi all,
I have a strange problem with my Gentoo system:
If I do not work on the computer for a while, some kind of screensaver will be activated because the screen is getting back. I am not in X11, just in the normal shell (bash).
I do not mind at all, but the problem is that I cannot reactivate the screen. I tried to move the mouse, press keys on the keyboard but the screen is staying black. It seems that the computer is hanging, because the numlock, capslock are not working anymore.
Maybe something with the power management? Has anybody an idea?
Thanks,
Marco |

Screen blanking is a normal part of console linux--it normally happens after like 5 minutes. I disable it in the kernel by altering the file
/usr/src/linux/drivers/char/vt.c
, in the function do_blank_screen, which now reads
| Code: |
void do_blank_screen(int entering_gfx)
{
struct vc_data *vc = vc_cons[fg_console].d;
int i;
return; //my line
WARN_CONSOLE_UNLOCKED();

I don't know why your computer would be freezing, but if it's not related to the screen blanking, whatever is happening may be more evident when you're not blacked out. |
