Description of problem: Suspend to memory fails to wake properly since installing FC6. This worked on FC5 (2.6.18-1.2200.fc5). Version-Release number of selected component (if applicable): 2.6.18-1.2798.fc6 How reproducible: Always. Steps to Reproduce: 1. Configure klaptop to suspend on lid close. 2. Close lid. 3. Reopen and hit any key on keyboard. Actual results: Display is powered off. I can ssh in from another machine and see that my KDE session is still running. Expected results: Display should be restored. Additional info: I'm unsure of the component. System is Sony Vaio VGN FS640W. Suspend/wake originally worked in FC4 using custom scripts. FC5 brought pm-utils to KDE and this worked until 2.6.17 kernels. All 2.6.17 kernels failed with the same symptom (display never comes back up, but system is alive). Finally, 2.6.18-1.2200.fc5 fixed this. Now FC6 breaks it again.
Exactly the same symptoms here, except that I didn't have this notebook before kernel 2.6.17 and therefore did not test with older kernels. But the video did not come back after a suspend with kernel 2.6.17; then the problem was corrected with 2.6.18 in FC5; and now wake up from suspend doesn't work again with FC6. I can verify that the system is running after wake up from suspend, but the display remains off. This is a centrino notebook with i915GM video chipset.
Maybe this bug is not kernel related. I think it may have something to do with the following bug in upstream xorg: https://bugs.freedesktop.org/show_bug.cgi?id=8542 This bug have been solved there. Has the patch been included in FC6's xorg?
Changing component to xorg-x11-drv-i810 since this does indeed seem to be a X-org driver issue rather than a kernel issue.
OK. I installed a new driver from http://www.fairlite.demon.co.uk/intel.html . This does fix the problem. I checked updates-testing and there is no xorg-x11-drv-i810 available. The copy from the above site reports: (II) Loading /usr/lib/xorg/modules/drivers/i810_drv.so (II) Module i810: vendor="X.Org Foundation" compiled for 7.1.99.2, module version = 1.7.2 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 1.0
This exact issue still occours with FC7 test 1, except I can get a 'bloom' (white display creeping in from the outside of the LDC in a very artistic fashion) on the screen if I hit a key. xorg-x11-drv-i810-1.6.5-10.fc7 xorg-x11-server-Xorg-1.2.0-1.fc7
I've got a new notebook with Intel i945GM video chipset and the problem is slightly different with this one: the display is turned on when the notebook resumes from suspend to RAM, but the backlight remains off. The new i810 driver from http://www.fairlite.demon.co.uk/intel.html did not solve this problem. The same problem still occurs in Fedora 7 test 4.
A correction on my last message: resume does work correctly with this notebook in Fedora 7 test 4. Don't know what went wrong in the first time I tested it.
