Pressing the power button to hibernate fails as well. I'm not sure what exactly is invoked by that but the display simply goes black and the system never hibernates.
Can you reproduce without the catalyst driver?
yes it's exactly the same there. Originally I tried with the radeon driver, but it just turns off the screen completely so I couldn't see the console output.
It seems that this depends on the WLAN Card, i will do some more test. This thread looks like the x121 with the AMD-350 CPU and AMD Chipset, is there someone how can test this on an intel core i3 x121e ?
Mario, interesting, what makes you think it's the WLAN card? Btw you're right I have the AMD one. I already tried to swap the WLAN miniPCIe for an Intel ABG PRO Wireless but the system did not recognize it. I assume the BIOS carries a whitelist of PCI IDs, which is a pain.
Stefan, you are so right. After some tests, it does not depend on the wlan card. And well, the same problem is still exist in F16 Beta. I can't seen anything in the logs for this issue ...
I have done some additional tests with some combinations of Fedora Releases and Kernels. Fedora 14 x86_64 with latest Kernel does hibernate correctly but F14 has no driver for the internal Ethernet an the WLAN Card. On F15 and F16 x86_x64 with all Kernels the Hibernation doesn't work. At last i have tried to disable the Ethernet, Bluetooth and WLAN cards. unloaded all Drivers for theses cards, but this doesn't help.
Reading your comment I just tried to hibernate on F16 with the latest F14 kernel and that fails for me. Still seeing a black screen only and waiting forever. Tried both running pm-hibernate manually and hibernate via gnome menu.
So after a much testing, i have no idea where the Problem is. F14 was the last working Fedora Release but without networking. Testing in F16 is a little bit strange, because the xfce4-power-manager is also not working on the x121e, while it works on the Thinkpad T410.
I have a Lenovo x100e that does not wish to hibernate or suspend under F16 (x86_64). Both features worked fine for me under F15. I get the same results as Comment 9, in that the screen goes black and the notebook remains powered on. System does not respond to keyboard or mouse inputs. I have to hold down the power button to switch off. If you require log files, configuration details, hardware details etc, I will gladly provide them.
[Mass hibernate bug update] Dave Airlied has found an issue causing some corruption in the i915 fbdev after a resume from hibernate. I have included his patch in this scratch build: http://koji.fedoraproject.org/koji/taskinfo?taskID=3940545 This will probably not solve all of the issues being tracked at the moment, but it is worth testing when the build completes. If this seems to clear up the issues you see with hibernate, please report your results in the bug.
