I've done some testing with pm-suspend and its flags. pm-suspend outputs nothing during suspend in any case. However I've found that there is an option which makes resume work. The flags and associated behaviours are:
- Without any flags, the computer suspends. When it comes back from resume, the disks spin up, USB becomes active and nothing else happens. Keyboard is usually responsive (I can toggle NumLock and use SysRq to reboot). If I try to switch to the graphical environment with Ctrl+Shift+F7, the machine hangs (keyboard not responsive anymore). - With --quirk-s3-bios, the machine hangs before activating USB. - With --quirk-vbestate-restore, resume does work. The screen doesn't turn itself on unless I hit Ctrl-Shift-F7. - With --quirk-vbestate-restore --quirk-dpms-on, resume works and the screen turns itself on. - The behaviour when using other flags is like that when using none. I suspect the driver for my ATI xpress 200 card. Until Intrepid, I used the fglrx driver because the free one wouldn't work. Now it does, and does a great job most of the time, but there are sporadic X crashes (see bug #336320) and I wouldn't be surprised if the driver was behind the suspend problem. Let me know if I can produce any additional information to further diagnose this. -- [Hewlett-Packard HP Compaq dc5750 Microtower] suspend/resume failure https://bugs.launchpad.net/bugs/336680 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
