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)

  1. 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,
  2. 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),
  3. 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.

Fist question can be answered here

Other display related question could be better troubleshooted if you did a reinstall on your nvidia drivers and started a new configuration.

Looks like solution to the 1st question (+reboot) solved this issue. Reinstallation of drivers helped as well (now it only hungs for some time, but seems to work). Thanks! – Zavaster Oct 15 '11 at 14:29
Welcome, I don't have any problems with my nvidia so if there is any information you can add or any suggestions please feel free to do so! ;) – Bruno Pereira Oct 15 '11 at 16:54
By the way, have you updated Ubuntu or had a clean installation of the newest version? – Zavaster Oct 16 '11 at 9:48
I havent yet, thats why I dont have any problems with it. – Bruno Pereira Oct 16 '11 at 12:40
