[ltp] Brightness and Suspend on T61 6459-CTO

[mstralka]

I have the T61 with Nvidia 140m and Intel Wireless 3945.  I installed Ubuntu
Gutsy last week.

I've been following the Thinkwiki instructions for Gutsy on the T61 but
cannot get the brightness controls to work in X.  When I run the xbacklight
command, I get this message:
No outputs have backlight property
I googled for that message but could not find any information about how to
make it work.
I can increase the brightness by switching to a VT and pressing Fn+Home and
then switch back to X.  I also cannot echo anything into
/proc/acpi/ibm/brightness - even as root I get "permission denied"

Suspend:
Suspend works but when I try to resume, the screen stays blank.  I followed
the Thinkwiki instructions for the Nvidia card but it didn't help.  I have
to do a hard-shutdown and startup to get it working again.  

Please let me know if anyone has solved either of these issues.
