--- Comment #36 from Csaba Kertész <csaba.kert...@gmail.com> 2010-10-21 20:20:54 --- I installed the newest kernel from here (http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2010-10-18-maverick/), kinda 2.6.36: My laptop became stable (suspend/resume and kwin work fine) again, but this bug happened again now! I logged in to my laptop via ssh and I try to gather as much information as possible and can be useful: ls /sys/class/backlight/acpi_video0 actual_brightness brightness max_brightness subsystem bl_power device power uevent cat /sys/class/backlight/acpi_video0/actual_brightness -> 15 cat /sys/class/backlight/acpi_video0/brightness -> 15 cat /sys/class/backlight/acpi_video0/max_brightness -> 15 cat /sys/class/backlight/acpi_video0/bl_power -> 0 cat /sys/class/backlight/acpi_video0/uevent -> EMPTY I can write the bl_power node (without any effect) as root, but other nodes give permission denied. Other subdirectories: ls /sys/class/backlight/acpi_video0/power control runtime_status wakeup runtime_active_time runtime_suspended_time wakeup_count cat /sys/class/backlight/acpi_video0/power/control -> auto cat /sys/class/backlight/acpi_video0/power/runtime_active_time -> 0 cat /sys/class/backlight/acpi_video0/power/runtime_status -> unsupported cat /sys/class/backlight/acpi_video0/power/runtime_suspended_time -> 0 cat /sys/class/backlight/acpi_video0/power/wakeup -> EMPTY cat /sys/class/backlight/acpi_video0/power/wakeup_count -> 0 I do not know if it has any problem with this lines in the /var/log/kern.log when waking up from suspend: ...
