So, any ideas on how to fix this? Let me know if I forgot to post something.Д 0:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 02)ДЇlags: bus master, fast devsel, latency 0Д¬apabilities: Vendor Specific Information: Len=0c Д 0:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) (prog-if 00 )ДЇlags: bus master, fast devsel, latency 0, IRQ 40 intel_backlight still works.Д§) Keys do not repeat (unless I do the 'reset' above).Дў) Extract and recompile the DSDT, fixing errors and warnings, compile custom kernel with new DSDT included.Д¤) Looked to see if there was a BIOS update. If acpi_backlight=vendor, then acpi_video0 gets renamed to ideapad, and brightness can no longer be changed through there. This does not happen in an X session.Д¦) I can set the screen brightness through /sys/class/backlight/acpi_video0/brightness (0-10) and /sys/class/backlight/intel_backlight/brightness (0-4882). If ambient light conditions change, these messages start again.ДЈ) The characters appear in the console occasionally (thought it only seems to happen before the login prompt or after a shutdown signal).Д¤) Occasionally I will get a system beep during boot (which may or may not be related).ДҐ) This problem seems to insert invisible characters into stdin, so I cannot login in a tty (unless I do the aforementioned 'reset'). If acpi_backlight=vendor, then nothing gets printed, though the tty console cursor does 'blip' as if a normal key were pressed.Дў) If acpi_backlight=legacy, the message 'ACPI: Failed to switch the brightness' pops up in dmesg repeatedly until I do what I think 'resets' the ALS, which is to press Fn+Down several times followed by Fn+Up several times. Also, if acpi_backlight=legacy, then the message 'ACPI: Failed to switch the brightness' pops up in dmesg. Here are the symptoms:ДЎ) The brightness controls (Fn+Up/Fn+Down) don't affect the screen brightness. This is going to be a little hard to describe, so please bear with me.

I have tried to figure this problem out ever since I first installed Arch a few months ago (coming from Fedora/Ubuntu where this never occured).
