Suspend with X display hangs on Dell CPxJ running X

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.6) Gecko/20011120 Description of problem: apmd with CHANGEVT=7 in /etc/sysconfig/apmd doesn't change *from* X display *to* text console before suspend. On some machines (such as Dell CPxJ), this causes the machine to freeze during suspend. Powering off and on causes reboot from scratch, including fsck. Version-Release number of selected component (if applicable): apmd-3.0final-34 How reproducible: Always Steps to Reproduce: 1. From X display, press [Fn]-[Esc] to suspend. 2. 3. Actual Results: The machine blanks the display and freezes with the power light on. When the power button is pressed, the machine powers off completely. Expected Results: The display should switch from the X display to VC-1 before initiating the suspend sequence. Suspend from a text VC works correctly on the CPxJ. Additional info: After switching to a text VC manually and suspending, the machine completes the suspend operation normally. Powering back on brings the machine back *and* switches back to VC-7 and the X display, as expected. This operation worked correctly in RH 7.1.
This is odd, because the apmscript still does the exact same thing: [ "x`pidof X`" != x ] && { [ "$CHANGEVT" != "0" ] && chvt 1 Also, I can't reproduce this problem (using different hardware, though). The ideal fix is to have Dell fix their BIOS (a sane notebook can suspend without switching to text mode); looking for a workaround... By any chance, does adding a delay after the chvt command help (try inserting "sleep 2s" after the [ "$CHANGEVT" != "0" ] && chvt 1 line)? Might be a race condition.
>The ideal fix is to have Dell fix their BIOS (a sane notebook can suspend >without switching to text mode) Yes, but: (1) It doesn't happen in Win2K. (2) Dell won't support Linux on this machine for me. Maybe you'd have better luck. I tried your sleep suggestion and a few other things, and I learned the following: The system is not freezing. But if I suspend from X, it does take about 30 seconds to shut off. When I restart it the first time, it shuts off again, by itself! The next time I turn it on, it starts up fine. If I change to vc1 manually, it suspends in a couple of seconds, and comes right back to vc7 on powerup. Make of that what you will.
Well, I have to give up on this bug. My CPxJ has been replaced by a Latitude C610. I'm running the Rawhide kernel and Mike Harris's XFree86-4.2 on that machine, and it suspends and resumes flawlessly (except for the NIC, but that's another story--bug to come, I think). I won't have the CPxJ to test, and as I seem to be the only complainant, I guess you might as well close this one. I set the status to WORKSFORME because it does now for both of us, but if something else would be more accurate, feel free.
