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 Codename: hardy Please let me now if I can help with more information. ** Attachment added: "dmesg_d630_ubuntu8.04" http://launchpadlibrarian.net/14250274/dmesg_d630_ubuntu8.04 -- Keyboard + Synaptic Touchpad randomly do not return from suspend on Dell 640m https://bugs.launchpad.net/bugs/99755 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
