Here's some more suggestion to get both suspend and hibernate working well with fglrx 7.12 on gutsy, with no Desktop Effects: in /etc/defaults/acpi-support: MODULES_WHITELIST="fglrx" MODULES="usbhid,uhci_hcd" SAVE_VBE_STATE=false POST_VIDEO=false DOUBLE_CONSOLE_SWITCH=true</blockquote><div> Thank you very much, that helped me finally solve the problem of hibernating and suspending! I worked now for 14 or more days on it... The only change I had to do was setting "SAVE_VBE_STATE=true". </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">The usbhid and uhci_hcd are useful if you have a usb keyboard, printer or camera, but not necessary if you don't. It's working well here with these changes.
