Suspend / Resume works only once

I have suspend / resume working flawlessly on a Dell Inspiron 8500, but it will only work one time. The 2nd time I try the laptop will suspend, but I am presented with a black screen on the resume. I can toggle Caps Lock, but cannot force an X restart or toggle to console. I have discovered that if I restart X after the first resume there is no problem. I need a little help working out how I can solve this. I am not really sure what I need to do. I have only ever had this working on a couple of distro's and lately I have been sticking more and more on Arch.

So questions:

What steps can I take to troubleshoot this problem?
What can I try ?
It seems like something is corrupted after the first resume and causes a problem on the second. What is likely to be the cause of this?

As I have poor support for LCD and DPMS using the open nv driver, I am running nvidia.

thanks for any input.

Same Problem here with an Dell Precision M6300 running the official NVIDIA-drivers...

Re: Suspend / Resume works only once

Just one suggestion:
can you reboot by trying the  SysRq??

Which will probably work, depending on the problems caused by the driver.

Or look at some log files before and after whatever happens: /var/log/X.0.log most likely.

Also what kind of workarounds are you using for suspend? Do they include

SwitchToTextMode yes

in your /etc/hibernate/common.conf ?

I confirm that the Switchtotextmode of the hibernate-script solves the issue for me.

Re: Suspend / Resume works only once

Hi,

Thanks for your replies. I am actually using pm-utils for suspend, but installed hibernate-script and tried running hibernate with SwitchToTextMode Yes and got the same problem.

As soon as the machine powerbutton is pressed to resume the laptop is unresponsive with a black screen. The only solution is to power off. I also tried the sysrq magic, but that would not work.

With both hibernate or pm-utils the first suspend / resume cycle works without a problem.

I tried pm-suspend with some of the vbe options, but none were able to resolve the issue.

I have checked X logs and hibernate / pm logs and all are clean. I don't believe that the resume part is logged. If there is a way of troubleshooting the resume it maybe of help.

thanks

Dan
