I have the same problem with a Sony Vaio FS640W laptop. See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=198998 . I reported this bug against the kernel and davej at redhat dot com changed it to pm-utils. I have no idea why. Everything works fine on 2.6.16-1.2133_FC5 and fails on all kernels after that. > The video card identifies, under "/sbin/lspci -v", as: > 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [ > Mobility Radeon 9600 M10] (prog-if 00 [VGA]) I have an Intel card: 00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03) (prog-if 00 [VGA]) [snip] > Following is a list of selected rpms currently installed > kernel-2.6.17-1.2174_FC5 (currently booted kernel) > acpid-1.0.4-2 > pm-utils-0.15-1 > gnome-power-manager-2.14.3-1 I think the only relevant components here are the kernel and pm-utils. The acpid doesn't participate in any suspend/wake stuff. I'm not using gnome-power-manager (KDE), but it only initiates the suspend and relies on pm-utils to do the Right Thing. I can successfully suspend and wake (with display intact) only with the 2.6.16-1.2133_FC5 kernel. My pm-utils is the same (pm-utils-0.15-1). > -- Lacking that, I would be interested in debugging this problem.
