Suspending Thinkpad R50e with Dapper

[lutzky]

Back in Breezy, I set up suspending like so: I have a script, /usr/local/bin/thinkpad-sleep, in which the most essential part is this:

...
cat /proc/bus/pci/00/02.0 > /var/cache/video.config
...
echo -n mem > /sys/power/state
...
cat /var/cache/video.config > /proc/bus/pci/00/02.0
...

It is those two 'cat' lines which finally solved suspending on my R50e (otherwise it would show a blank screen on resume).
Now, dapper comes with its own suspending mechanism, and I'd rather use that. So I changed /etc/default/acpi-support to enable SAVE_VIDEO_PCI_STATE (which, as far as I can tell, does exactly that). But no dice. Video comes up blank (screen completely OFF). Any ideas?

Hello!
You might want to check this post:
http://www.ubuntuforums.org/showthre...highlight=r50e
and here: http://www.thinkwiki.org/wiki/Instal...nd_Hibernation
now hibernate and sleep are working:
fisrt:

Open a terminal and enter this command: sudo gedit /etc/default/acpi-support And uncomment "ACPI_SLEEP=true" (by removing the # character in front of it)

And in the same file, uncomment "restore_pci_somethingIforgot"
Then:

sudo cp /etc/acpi/sleep.sh /etc/acpi/sleep.sh_backup sudo gedit /etc/acpi/sleep.sh Replace the line "echo -n $ACPI_SLEEP_MODE >/sys/power/state" with (take from Problem with display remaining black after resume): # change to console 1 FGCONSOLE=`fgconsole` chvt 6 # safe video state cat /proc/bus/pci/00/02.0 > /tmp/video_state # sync filesystem sync # sync hardware clock with system time hwclock --systohc # go to sleep echo -n 3 > /proc/acpi/sleep # waking up # restore system clock hwclock --hctosys # restore video state cat /tmp/video_state > /proc/bus/pci/00/02.0 # change back to X chvt $FGCONSOLE # clean up behind us rm /tmp/video_state

then, edit your Xorg.conf

Section "Device" Identifier "Intel Corporation 82852/855GM Integrated Graphics Device" Driver "i810" BusID "PCI:0:2:0" Option "VBERestore" "true" EndSection

It works fine with my r50e laptop.
I don't use kpowersave, though, but klaptop !
Suspend work from calling the /etc/acpi/sleep script in the console or calling it from right-click on klaptop>suspend.

Bye!

Thanks, worked very well. However, it seems like too much work... shouldn't this be autodetected and made to 'just work'? I was so impressed with Dapper's usability for new users with laptops.

I know, it should be detected, but it seems that there is a bug!
Check in launchpad
r50e thinkpad aren't supported right away...

bye

thanks,

Open a terminal and enter this command: sudo gedit /etc/default/acpi-support And uncomment "ACPI_SLEEP=true" (by removing the # character in front of it) And in the same file, uncomment "SAVE_VIDEO_PCI_STATE=true"

Did the job for my IBM Z60m.
The hibernate test and the suspend test worked.
