After a few resumes with my T43, I get "big green boxes" on my consoles tty1 and tty2. tyy3 to tty6 stays completly black (there should be login prompt). But X still working fine.

This is a minor issue, but anyone with the same problem and a fix/workaround?

I have a similar issue on my T60. It seems like the problem is with the framebuffer; that the card is attempting to use the lowest resolution possible when I have the framebuffer set much higher, but that's just my intuition. I'm using hibernate with both EnableVbetool and VbetoolPost set to yes.

An interesting thing is that if I manually call hibernate from an xterm inside X, I get no negative effects. It even fixes the console "big green boxes" if I previously suspended not in X. Also, on resume I see the following messages on the xterm (all previous output is cleared): 

 Allocated buffer at 0x11010 (base is 0x0)

Any ideas?

Just to update/confirm: suspend to RAM only works if I have X running, and I switch to the console running X after resuming. Editing the ACPI sleep script to switch to vt 7 before switching back to the original console seems to work fine, though. It just means that I can't suspend to RAM if I'm not running X. (Putting a check for that in the ACPI sleep script would also be a good idea.) I've tried using EnableVbetool, VbetoolPost, RestoreVCSAData, and RestoreVbeStateFrom from hiberante, but none seem to solve this without switching to X.

Fix for garbled framebuffer console.

try to add following kernel option to /boot/grub/menu.lst

acpi_sleep=s3_bios,s3_mode

i think the s3_mode fixed the green boxes for me. (kernel 2.6.16) --Ladoga 06:46, 5 August 2006 (CEST)
