I have serious issues with Ubuntu (64 bit) after upgrading system from 11.04 to 11.10. My hardware: Asus G53SW (i7-2630QM, 8GB RAM, GF GTX460M)
- Power (UPower) - when I change behaviour of lid open/close looks like my settings doesn't work at all. Changed closed lid to do nothing and still my notebook suspends when i close the lid,
- Resolution - system hangs when I try to change resolution. Something weird happens and screen (just before hangs) looks like having a shifted position (like absolute with shift),
- Display - when I attach external display (with adaptor ring, DVI -> HDMI) and trying to turn it on as separate screen / twin view system hangs on with similiar effects as stated in 2nd point.
Everything worked well on Ubuntu 11.04, so it's 11.10 issue for sure.
Bonus question: how can I change behaviour of special keys like keyboard backlight? acpi_listen doesn't list them, I read that it's something with WMI.
