Hi,

After I resume from suspend, my screen is black. "Ctrl, Alt and F1/7" etc. does nothing, and pressing the power button or "Ctrl, Alt and delete" does nothing. All the lights come back on and the hard drive spins back up, but there's nothing on the screen. I'm using Debian Lenny on an Acer TravelMate 290 laptop.

I'm using the Intel graphics driver 2.3.2. With other distributions that use newer graphics drivers, it seems that from version 2.6 suspend works without any problems.

Without running Debian testing (which uses version 2.9) or waiting for it to be released as stable, I want to be able to use suspend. I've tried every possible "quirk" with pm-suspend and none seem to help. Can anyone suggest something else to try?

EDIT: I just found out that if I hibernate and resume (which works fine) then suspend works fine afterwards... until I restart my laptop. Then I must hibernate again before suspend will work. How strange! Any ideas with this?

Thanks

see if this works:

That works, but I have the same problem when I resume.

What could be different between "my computer after a fresh boot" and "my computer after resuming from hibernation"? If I can find the difference maybe I can get suspend to work without having to hibernate first.

Thanks

After a quick look, it seems that after a hibernation, /var/run/pm-utils/storage/ is filled with a few files.

state:console with the value of 7
parameters which is blank
parameters which lists a number of quirks

I've tried putting these files (after making a copy of them) there before a suspend (after a fresh boot) but this doesn't help.

I'm thinking that the good old Travelmate 290 has some compatibility issues with newer Linux distributions. I have had issues with the newer Ubuntu versions running correctly on my TravelMate 290. Anything higher than 8.04 causes issues (up to 9.1) - different issues for each version. Mostly video and sound issues. After messing with the newer versions for way too long, I went back to Ubuntu 8.04, which runs almost perfectly out of the box on the Travelmate 290.

I have similar issues with behaviour after suspend/hibernate. Although I haven't yet resolved them completely, this resource helped a lot in understanding what was going on. Hope you find it useful too.

Similar issues with my Toshiba A215-S4757. I'm just begun the journey in trying to resolve this suspend problem. I just tried Hibernate first, then suspend - same effect. Computer returns, but screen does not. Also (separate issue), after I Hibernate wifi-radar cannot connect to any networks. Is there a simple solution to this subsidiary problem?

I'll subscribe to this thread and post any updates I have related to getting the screen to come back on. Listed below is my original post to debian-laptop newsgroup:

I have looked for a solution in forum search, google, and other misc. Debian help pages. I've found many comments, but no solution.

The Problem: After suspending successfully (apparently, evidenced by blinking amber light) and resuming, the screen remains off. No backlight... blank screen.

Attempts at solution:
1. without the screen on and after resume I ctrl-alt F1, CTL-ALT 7, CTR-ALT 'whatever' and no effect on screen.
2. after resume with no screen, CTRL-ALT 1, login as root, type halt. computer shuts down.
3. after resume with no screen, CTRL-ALT 1, login as root, restart gdm, no effect.
4. after resume with no screen, CTRL-ALT 1, ALT-F7, no effect.
5. " " " " " """"""""""""""""""""""", Funtion key - F6 and F7 to adjust brightness, no effect

Is there a way at the command prompt to kill the screen and start it up again? I'm pretty much out of ideas.

Environment: Running Lenny with Linux Kernel 2.62 AMD64 (I dual boot w/ vista). Toshib A215-s4757, ATI Radeon graphics.

Thank you in advance for any help or direction.

This works for me:

"pm-suspend --quirk-vbe-post" (without the quotes, of course)

This option will attempt to reinitialize the video card when
resuming from suspend, using the same code the system BIOS uses at
boot in order to initialize the video hardware. Not all video cards
need this, and using this option on systems where it is not needed
can cause a system to lock up when resuming.

Now I'm trying to figure out how to reset my network adapter because after I return from suspend I can't see any wireless networks.

Resolved:


uncommented quirks under my laptop in the following file,

/usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-toshiba.fdi

and added <merge key="power_management.quirk.quirk-vbe-post" type="bool">true</merge>

wifi problem (no wifi detected after resume) resolved by creating a file in /etc/pm/config.d
I named the file: madwifi-fix and it included:

SUSPEND_MODULES="$SUSPEND_MODULES ath_pci"
