Suspend to Memory/Wake Fails on FC6
Last modified: 2007-11-30 17:11:47 EST
Description of problem:
Suspend to memory fails to wake properly since installing FC6. This worked on
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure klaptop to suspend on lid close.
2. Close lid.
3. Reopen and hit any key on keyboard.
Display is powered off. I can ssh in from another machine and see that my KDE
session is still running.
Display should be restored.
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:
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 188.8.131.52, 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.
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.
Closing per comment 7.
