Hello, I have a dell inspiron 4150 laptop. Previously it suspended (to ram) and resumed well, when I was using apm. Recently I tried on my latest kernel update to finally evolve and start using acpi. Unfortunately when suspending to ram with acpi (using "acpitool -s") the display comes back garbled and cannot be corrected. I have the most recent bios version A06 (I doubt any more will come out as the laptop is 2 - 3 years old). My distro is debian unstable (relatively recent) and my kernel versions and power management info sections are listed below. I have the same symptoms whether I do this from an xterm within X11 (xorg) or from the console. After I resume, switching between consoles and X11 does not help. About the only way I can "exit" the situation is to press the power button which triggers acpi to nicely shutdown the machine. Some google searches showed others with similar problems, but they were all 2 - 4 years ago. What could be the problem, and what could I try to correct it? thanks for any help, donfede ###################################### ########### # # working apm configuration # # Linux kernel version: 2.6.22.5 # Power management options (ACPI, APM) # CONFIG_PM=y CONFIG_PM_LEGACY=y CONFIG_PM_DEBUG=y # CONFIG_DISABLE_CONSOLE_SUSPEND is not set # CONFIG_PM_TRACE is not set # CONFIG_PM_SYSFS_DEPRECATED is not set # CONFIG_SOFTWARE_SUSPEND is not set # # ACPI (Advanced Configuration and Power Interface) Support # # CONFIG_ACPI is not set CONFIG_APM=y # CONFIG_APM_IGNORE_USER_SUSPEND is not set CONFIG_APM_DO_ENABLE=y CONFIG_APM_CPU_IDLE=y # CONFIG_APM_DISPLAY_BLANK is not set # CONFIG_APM_ALLOW_INTS is not set # CONFIG_APM_REAL_MODE_POWER_OFF is not set ########### # # unfortunately not working acpi configuration # # Linux kernel version: 2.6.23.9 # Power management options (ACPI, APM) # CONFIG_PM=y # CONFIG_PM_LEGACY is not set # CONFIG_PM_DEBUG is not set CONFIG_PM_SLEEP=y CONFIG_SUSPEND_UP_POSSIBLE=y CONFIG_SUSPEND=y CONFIG_HIBERNATION_UP_POSSIBLE=y CONFIG_HIBERNATION=y CONFIG_PM_STD_PARTITION="/dev/hda1" CONFIG_ACPI=y CONFIG_ACPI_SLEEP=y CONFIG_ACPI_PROCFS=y CONFIG_ACPI_PROC_EVENT=y CONFIG_ACPI_AC=y CONFIG_ACPI_BATTERY=y CONFIG_ACPI_BUTTON=y CONFIG_ACPI_VIDEO=m CONFIG_ACPI_FAN=y # CONFIG_ACPI_DOCK is not set CONFIG_ACPI_PROCESSOR=y CONFIG_ACPI_THERMAL=y # CONFIG_ACPI_ASUS is not set # CONFIG_ACPI_TOSHIBA is not set # CONFIG_ACPI_CUSTOM_DSDT is not set CONFIG_ACPI_BLACKLIST_YEAR=0 # CONFIG_ACPI_DEBUG is not set CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_SYSTEM=y CONFIG_X86_PM_TIMER=y # CONFIG_ACPI_CONTAINER is not set # CONFIG_ACPI_SBS is not set # CONFIG_APM is not set - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
