Hi all,

on an ASUS M2400N [*] with both plain vanilla Linux Kernel 2.6.1 and
2.6.1 + acpi-20031203, the machine appears to suspend to RAM without a
problem and it also apparently comes back, but the screen is dead.

Here is the dmesg output for the suspend to RAM / resume cycle:

When trying to get/set the LCD status via /proc/acpi/asus/lcd, dmesg
shows

 Asus ACPI: Error reading LCD status

Suggestions, anyone? If you need more info, let me know.

Georg

Try passing acpi_sleep=s3_bios or acpi_sleep=s3_mode to the kernel on
boot - also try while running X, switch away before suspend and switch
back afterwards. The problem is that the kernel doesn't know how to wake
the video hardware back up after S3 - the kernel parameters are hacks
that try to provoke it back into life, and X is sometimes able to
reinitialise stuff itself.

Where would the people maintaining the video driver have to look?

Yes.

Interesting. I'll try that.

May this be a problem of the fb driver then?

Thanks for your input,

Exactly the same behaviour.

Try hitting the hardware function key that swaps the CRT/LCD and/or the 
function key that changes the font.

Works on my laptop.  Really annoying two-fold issue.  First, the screen 
is blank, second, I have to blindly run setfont to change the garbage 
font to a readable font.

I'm not running an fb, just an nvidia card in text mode on a Dell 
Inspiron 8200.

None of the keys make any difference.
