PostPosted: Sat Feb 04, 2006 6:41 am    Post subject: Blank screen after resuming from Suspend Reply with quote

i'm noticed many, many posts about people whose laptops seem to work after coming out of suspend, but whose LCDs don't display jack. i was afflicted with this problem recently, and i wanted to share my solution.
some background: i'm using suspend2-sources and hibernate-script's hibernate-ram script to suspend using /sys/power/state mem
when i come out of suspend my computer is fine, but the screen is blank.
but it is reenabled if the backlight is changed by writing an integer to /proc/acpi/video/GFX0/LCD/brightness.
so, my suspend script now has an additional line that changes the brightness after resuming and everything is just peachy.
if anyone needs scripts to help you do this, i can post them.

i hope this helps at least one person!

Hello
I have the same problem... I can suspend to disk without any problem, but when i try to switch back from suspend yo ram, the screen is blank, even switched on...

The scripfile is missing from my computer, and the /proc/acpi/video directory is empty.

I think you have to set "CONFIG_ACPI_VIDEO" to "yes" in your kernel menuconfig.

I'm interested with your hibernate-script (I think about hibernate.conf) and supposed that the line you add is something like :
Code:
echo "1" > /proc/acpi/video/GFX0/LCD/brightness
no ?

Thanks for sharing your tips.

In the kernel config the CONFIG_ACPI_VIDEO is set.

The /proc/acpi/video driectory was made by the system on your machine ?

Here is my /etc/hibernate/hibernate.conf file.. :

# Example hibernate.conf file. Adapt to your own tastes.
# Options are not case sensitive.
#
# Run "hibernate -h" for help on the configuration items.

##############################################################################
### Choose your Suspend method. You currently have 3 choices:
###
### suspend2 Software Suspend 2 (requires kernel patches from
### http://www.suspend2.net/)
###
### sysfs_power_state Uses /sys/power/state to suspend (activates pmdisk
### on kernels < 2.6.8, or vanilla swsusp otherwise).
###
### acpi_sleep Uses /proc/acpi/sleep to activate swsusp, or other
### ACPI sleep state supported by your machine.
###
##############################################################################

### suspend2 (for Software Suspend 2)
UseSuspend2 yes
Reboot no
EnableEscape yes
DefaultConsoleLevel 1
#Compressor lzf
#Encryptor none
# ImageSizeLimit 200
## useful for initrd usage:
SuspendDevice swap:/dev/hda3
## Powerdown method - 3 for suspend-to-RAM, 4 for ACPI S4 sleep, 5 for poweroff
# PowerdownMethod 5
## Any other /proc/software_suspend setting can be set like so:
# ProcSetting expected_compression 50
## Or traditionally like this:
# Suspend2AllSettings 0 0 2056 65535 5
## Or even from the results of hibernate --save-settings with this:
# Suspend2AllSettingsFile /etc/hibernate/suspend-settings.conf
## For filewriter:
# FilewriterLocation /suspend_file 1000
# VerifyFilewriterResume2 yes
# ProcSetting userui_program /sbin/suspend2ui_text

### sysfs_power_state
## To use /sys/power/state to suspend your machine (which may offer
## suspend-to-RAM, suspend-to-disk, standby, etc) comment out all the options
## above for Software Suspend 2, below for acpi_sleep, and uncomment this line.
## You may replace mem with any one of the states from "cat /sys/power/state"
# UseSysfsPowerState mem
# PowerdownMethod shutdown

### acpi_sleep
## To use ACPI to suspend your machine (via /proc/acpi/sleep), comment out
## all the options above for Software Suspend 2 and sysfs, and uncomment this
## line. The number refers to the ACPI sleep state - 3 is suspend-to-RAM and
## 4 is suspend-to-disk.
# UseACPISleep 4

Hmm... Mine doesn't seem to be supported, or I'm not configured correctly. I have an Intel 855GM video card.
Code:
$ cat /proc/acpi/video/IGD/LCD/brightness
<not supported>

Leipoxa: how come you have IBM, Asus, and toshiba extras selected?
other than that, i must say your config looks fine.

yoyo: rather than using hibernate.conf's afterresume settings, i have /etc/acpi/events call a script on the poer event (power button pressed) that executes my pre-suspend and post-suspend stuff, that included. this is mostly because i'm not sure about most of hibernate.conf's syntax, and i like to be able to change the before-and-after suspend commands a lot.
so, yeah, nothing very interesting.

anyone who doesn't have /proc/acpi/video: you might want to do some searching on the 'net for independent or proprietary drivers for your specific laptop line... lot's of the ACPI stuff is really different among different brands and generations. i don't know much about acpi, but most laptops should support this stuff - you might just need to look for drivers.

PostPosted: Fri May 26, 2006 3:31 pm    Post subject: :D Finally I got it Reply with quote

Hello, I have been trying to hibernate-ram for 1 month with any succes. Yesterday I finally achieve it.
I just want to post what I did for users with ATI-DRIVERS-8.24.8, I'm on a Dell 600m.

First.
I emerged all the hibernate sources (the kernel patch, the script...)

After this, I edited my /etc/X11/xorg.conf
I changed the line from "on" to "off"

Option "UseInternalAGPGART" "off"


then, I compiled the intel-agp and ati-agp as modules.

Here it was were I got the big problem.
When the fglrx driver try to load, It did not find any agp controller. I though that the fglrx would load it by itself. That is why is edited my /etc/modules.autoload.d/kernel2.6 and wrote

ati-agp (*Here it can be also intel-agp, both worked for me )


After the X env. is loaded with fglrx but with an external agp-driver, the lock of the screen after hibernating will be off.
Ohh! I almost forgot it, I don't use framebuffer, Honestly, I like it very much, but I prefer the hibernate-ram feature.

The only configuration file you have to edit id the /etc/hibernate/ram.conf

Here it is.

Code:


# Example ram.conf file for suspending to RAM. Adapt to your own tastes.
# Options are not case sensitive.
#
# Run "hibernate -h" for help on the configuration items.

### sysfs_power_state
UseSysfsPowerState mem

Why is working? lol, I know many things are commented, but It works for me, very well.
After this editting, you can safely do hibernate-ram as root, And everything will be saved, After openning the lid again, The desktop will appear as you left it.



As I said in the beggining, I wanted to post this because I was going crazy with hibernate-ram, Now that I got it, I want to share even if it is useful for others. If it does, PERFECT!!! :D :D :D

I have the same problems. . .it goes to sleep fine, but refuses to turn the screen on afterwards. It used to be a hit or miss sort of thing, but now, It never brings the screen back. It has this problem with X and on a terminal. Like someone else's post, I get <not supported> when trying to write to /LCD0/brightness. As far as I can tell, I confiured my kernel correctly, which of course means that the problem is in my kernel. I have acpi->video compiled into the kernel. is there anything else important that anyone knows of?

IBM thinkpad Z60m
relevant specs that come to mind
pernitum M
40 GB SATA
intel mobile 915 GM graphics card
intel 2200BG wireless card
kernel 2.6.17-r6-mm2
gcc 4.1.1
As stated earlier, I had hibernate-ram working as of about 2 weeks ago, then it stopped coming back properly. I'm pretty sure I haven't changed my kernel in that time.

If you have an intel card, try adding 'Option "VBERestore" "true"' to the device section of xorg.conf. Along with enabling vbetool that did the trick for me (I have a 945GM). It seems that vbetool's only purpose for my setup is to set dpms to 'on' again.

weird, I thought I posted back here, I guess the requet timed out. so the problem wasn't dpms. I could set the dpms to on from an ssh connection, but it didn't help. I ended up disabling VBEtool altogether, and it seems to work. If anyone really wants to dive deeper into this, I can give a bit of a description of what's been going on. Some realy weird things have happened. I'm having some problems when I try to kill X or I just close my lid without sleeping, or suspending to disk. I have dri, suspend to ram and a FB working, so I don't really care about the disk, and I guess I can live with X refusing to die.
