Hi,
I have a Thinkpad T61 laptop and use the Nvidia graphic driver. I think this configuration is pretty common.
However, resuming after suspending to RAM randomly hang on a blank screen. Sometimes, it finally resumes after minutes, and sometimes I have to cold reboot.
I could not find the exact issue reported on the net. Does anyone else have the same laptop here ?
Best Regards.
Check the /var/log/pm-suspend.log file when it fails. If you are lucky it will show you the cause. Also check out http://en.opensuse.org/Pm-utils
For my Dell Vostro with NVIDIA I had to add the following files.
cat /etc/pm/config.d/nvidia DISPLAY_QUIRK_VBE_POST=false & cat /etc/pm/config.d/s2ram S2RAM_OPTS="-f --acpi_sleep 1
Your mileage may vary (try modifying the acpi_sleep value)
Manne ps. I have this working, but every now and then (every 30 times) it just reboots (as if it was not set to resume the suspend)?
I tried your tweaks and other combinations, but no luck. In the log file, the only noticeable message is : ===== 2008-12-05 20:06:13.197708442 running hook: /usr/lib/pm-utils/sleep.d/10NetworkManager ===== Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. I am not sure this is the cause of the hang. Maybe it comes from hal and its quirks ? Strangely, when I used Debian on this machine before switching to Suse, I did not have this issue. So, there must be a way...
