Suspend problem with FC5 and FC6

sammy11 · 11-09-2006, 01:05 AM

When I chose "suspend system", the system goes to a text mode with a blinking cursor and cannot wake up. Even ctl-alt-del does not work at that state. Does anyone know how to solve this problem? (or is there a special key for wakeup?).
Tried FC5 and FC6, all the same.
System: Dell Precision 470, with dual Xeon, 4GB RAM, nVidia card.
Thanks

Hello sammy11,

The problem here is that your system is not supporting suspend as it stands. Possibly some modules are not being loaded at boot or some hardware is not compliant and may need an upgrade. I'm not sure how to troubleshoot this exactly however I would examine system logs under /var/log/ and see if these shed any light. At a guess it would be your nvidia drivers - are you using the proprietary version or those included with xorg?

I am using nVidia proprietary driver. The driver comes with Fedora is too slow when dealing images.
I checked the Xorg.0.log and didn't know what to see there. One related problem is with "init 3", the system hangs at "init 3". But I can get into level 3 mode by editing inittab file. Is this related to the suspend problem?
Thanks,

Hi sammy,

init 3 is the runlevel it is hanging at - default is 5. I would suggest temporarily switching to the xorg driver. Edit the /etc/X11/xorg.conf and change

Driver "nvidia"

to

Driver "nv"

then restart X or just reboot. Then try suspend. Whilst I realise that you need the accelerated driver, a major cause of problems in a linux kernel are closed source binary blobs that dont live happily with everything else. Let me know how you get on.

Regards
Chris

I tried changing "nvidia" to "nv" in xorg.conf. The suspend problem is still there. I think it simply turned the PC off, not just freez it. For some of my software to run, I do need nvidia driver (with opGL library). "nv" driver just won't run them. Any where to check? Why "init 3" works in "inittab" file (reboot into text mode), but not from command line?
