** Description changed: System fails to resume after suspend (either while plugged in or running on full battery power). When I open the laptop after suspending, the keyboard lights up & fan is spinning, but the screen is blank. For a brief moment, there is a login request in the upper left corner (it lasts for maybe half a second). The keypad does not respond (at least, not in any visible way - the caps lock light does not turn on/off when the button is pressed), pressing the power button does nothing (there is no suspend button). A hard shutdown (by holding the power button) is the only current solution. I have tried: Editing /etc/default/grub. Added "acpi_sleep=nonvs" to arguments of GRUB_CMDLINE_LINUX and GRUB_CMDLINE_LINUX_DEFAULT followed by sudo update-grub Installed hibernate package: sudo apt-get hibernate Checked for latest BIOS, but it is current (A08) Upgraded to newer kernel (from 2.6.38-8-generic): sudo apt-get update apt-cache showpkg linux-headers sudo apt-get install linux-headers-2.6.38-10 linux-headers-2.6.38-10-generic linux-image-2.6.38-10-generic --fix-missing Unbinding (and re-binding on resume) suggested at http://ubuntuforums.org/showpost.php?p=11007955&postcount=15 None of these attempts fixed the problem. And just in case it's not included in the bug report, I'm using 11.04 (Natty) on a Dell XPS 15z with an i7-2620 and 8 GB RAM. Thanks in advance for any info.
