Before the upgrade my /var/log/kern.log used to contain these messages: radeonfb (0000:01:00.0): suspending to state: 2... radeonfb (0000:01:00.0): switching to D2 state...
now I only get radeonfb (0000:01:00.0): suspending to state: 2... I suppose I should try to modprobe radeonfb force_sleep=1 next. Maybe my laptop (Thinkpad T42 2373-FWG) is not mentioned in the whitelist? http://thinkwiki.org/wiki/Problem_with_high_power_drain_in_ACPI_sleep asks for the output of lspci -d "1002:*" -vn, here is mine: 01:00.0 0300: 1002:4c57 Subsystem: 1014:0530 Flags: bus master, stepping, fast Back2Back, 66MHz, medium devsel, latency 66, IRQ 11 Memory at e0000000 (32-bit, prefetchable) [size=128M] I/O ports at 3000 [size=256] Memory at c0100000 (32-bit, non-prefetchable) [size=64K] [virtual] Expansion ROM at c0120000 [disabled] [size=128K] Capabilities: <access denied> -- Excessive battery usage in ACPI sleep https://launchpad.net/bugs/65856 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
