After 12.04 that had some problems with wifi, bluetooth, touchpad and battery life
I have installed ubunt 12.10. Seems that some problems have been solved like touchpad but ...
1-wifi need to be close to the access-point to work
2-battery life still a problem
3-bluetooth does not recognize other devices
4-some function key like brightness that worked in 12.04 does not work anymore
It seems that as of the latest update to the 3.5.0-18(29) kernel, I have lost both my external USB ports. Anyone else experience this?
Backlight function keys Fn+F5 & Fn+F6 have been fixed in recend nightly mainline kernel "drm-intel-experimental":
Kernel works for me, seems very stable (Ubuntu 12.10).[...]
i915: initialize CADL in opregion
If you use kernel parameter "acpi_backlight=vendor", remove it!
in wiki? This enables runtime power management for Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller, which is broken since linux 3.5.0.
This has been fixed in linux 3.6.0
Device goes to D2-sleep-state, but doesn't support it either... In Linux 3.6 D3cold will be used instead, which should be supported by the xHCI-Host-Controller...
Since then you should disable automatic runtime pm for xHCI Host Controller only or delete the complete script.
Is this fix also available in mainline kernel release (3.6.3)?
I'm not sure how to upgrade the kernel: should simply download and install (dpkg -i) all 3 .deb files, and update grub?
Thanks for you help!
