Suspend doesn't work with shipped /etc/default/acpi-support (Hardy, fglrx)

[Adrian VELICU]

I'm using Hardy beta with a Radeon Xpress 1150 card with the fglrx driver.
Suspend doesn't work with the shipped /etc/default/acpi-support.
The following file fixes the problem:

ACPI_SLEEP=true
ACPI_HIBERNATE=true
ACPI_SLEEP_MODE=mem
MODULES=""
MODULES_WHITELIST="fglrx"
SAVE_VBE_STATE=false
VBESTATE=/var/lib/acpi-support/vbestate
POST_VIDEO=false
USE_DPMS=true
DOUBLE_CONSOLE_SWITCH=true
HIBERNATE_MODE=shutdown
LOCK_SCREEN=true
STOP_SERVICES=""
RESTART_IRDA=false
ENABLE_LAPTOP_MODE=false
SPINDOWN_TIME=12

..however hibernation still doesn't work (the system switches to a vt, then returns to the X session without hibernating)

I have a Mobility Radeon 9700 and suspend to RAM fails on the second resume cycle, blank screen, no backlight, no keyboard lights. I tried the above configuration (except for the laptop mode setting) and it did not help.

I set /sys/power/pm_trace to 1 and got this:
Sep 6 04:22:10 ee-pdouble kernel: [ 10.940820] registered taskstats version 1
Sep 6 04:22:10 ee-pdouble kernel: [ 10.940909] Magic number: 0:716:362

Does "sudo /etc/acpi/sleep.sh force" work better for you? If yes, a workaround is to modify the hal scripts (/usr/lib/hal/scripts/hal-system-power-suspend-linux) to call /etc/acpi/sleep.sh instead of pm-suspend (around line 74, comment the if block and replace it).

That works for me.

I tried "sudo /etc/acpi/sleep.sh force", no change. I submitted a new bug report since the hardware is different.

I followed instructions given at:

http://wiki.cchtml.com/index.php/Ubuntu_Hardy_Installation_Guide#Method_2:_Manual_Method_.28installing_Catalyst_8.6.29

With the latest drivers provided and the changes suggested to bring to /etc/default/acpi-support, suspend-to-ram works now on my nw8240 equipped with and ATI MOBILITY FireGL V5000 graphics controller with 128 MB (Note:
Linux report it as ATI Technologies Inc Radeon Mobility X700 (PCIE)). On the nw8240, it is necessary to get the latest ATI drivers as the one provided in Hardy's repository still does not provide suspend-to-ram capabilities on this video card.

Thus, I confirm that changes are necessary in this file for ATI cards.
