Public bug reported: Very strange, but reproductible :).
I'm working on linux-image-2.6.24-20-generic , 2.6.24-20.38 , on i2c duo, 64 bit system, with ubuntu-desktop 1.102. Sleeping/resuming works fine. But when I switch to kdm/KDE, sleeping and resuming brings blank screen, and only hard reboot is possible. How to reproduce: a) - from kdm/kde - closing lid. 1. sudo dpkg-reconfigure kdm 2. choose kdm as DM 3. reboot laptop 4. login, 5. close lid, wait until computer is suspended 6. open lid RESULT: fans starts like during normal resuming, but blank screen, nothing, sometimes caps-lock led is blinking. b) - from console, sleeping from cmdline, still kdm is default DM 1. logout from KDE, 2. <ctrl>-<alt>-<f1> - switch to console #1 3. login 4. sudo -s 5. /etc/init.d/kdm stop 6. pm-suspend, wait until computer is suspended 7. press power button RESULT: fans starts like during normal resuming, but blank screen, etc... BUT!: when i typed 'reboot' on the keyboard (screen is still blank), machine rebooted. c) - back to gdm/gnome 1. dpkg-reconfigure gdm, choose gdm as default DM 2. login 3. close laptop lid 4. wait until suspended, open lid RESULT: resuming works perfectly.
