Comment 20 for bug 99755

I have the same problem on my Dell Latitude D630 (Intel X3100 1440x900).

I use the laptop with it's internal peripherals only:
- No docking station
- No external USB devices (in use before, after and during suspend)

Ubuntu 7.10 was installed from CD (ubuntu-desktop-x86) late 2007 and I've just upgraded to Ubuntu 8.04 a week after 24th April. The suspend worked without the mouse/keyboard freeze with 7.10.

Problem0: Keyboard and mouse freeze on resume from suspend.
Problem1: Mouse responsiveness slows down on resume form suspend.
Problem2: Screen has defects (gray stripes) on resume from suspend.

Problem 0 and 1 are most frequent. Problem2 has only happened two or three times the last two weeks.

All the problems are solved by closing and re-opening the lid once or twice, but sometimes the responsiveness stays slow.

Here is a little lid-closing-experiment:

Only running on battery (always waiting for the wireless to connect before next lid-close):
#Lid-close - Comment
0 - Ok
1 - Ok
2 - Ok
3 - Ok
4 - Slow Mouse Respons (SMR)
5 - SMR
6 - SMR
7 - SMR
8 - SMR
9 - SMR

Plugged in power cord, running on AC-power:
0 - SMR
1 - SMR

Unplugged power cord (with lid closed), running on battery power:
0 - Freeze (mouse and keyboard freez)
1 - Ok, Fixed SMR problem lasting since lid-close 4 on battery.
2 - SMR
3 - Ok
4 - SMR
5 - SMR
6 - Ok

The little experiment confirm what I've experienced during normal usage. I had a notion that the freeze had something to do with the power cord usage. That's the reason for the in-/out- plugging during the "experiment".

I've attached my dmesg and lspci output.

My uname -r:
2.6.24-16-generic

My lsb_release -a:
Distributor ID: Ubuntu
Description: Ubuntu 8.04
Release: 8.04
