My system always was able to suspend and resume properly under 12.10 and 12.04 and earlier, but immediately after the 13.04 upgrade, I find it crashes on trying to return from suspend. Sometimes it just repaints part of the screen with a bit of the startup/splash graphic then halts, and sometimes it gets a bit further, blanking the screen and showing a mouse pointer - which is frozen.

Hardware is a AMD Phenom(tm) II X4 945 Processor × 4 on an nvidia motherboard, 8GB RAM, GeForce GTX 550 Ti/PCIe/SSE2/3DNOW!, running Ubuntu 13.04 32 bit.

Can't find anything that seems relevant in the system log - maybe I don't know what to look for though, even which log. I will post anything requested.

I also noticed that the system became unresponsible after waking up from suspend. I was able to log in to console (CTRL+ALT+F1) and in dmesg I got repeating messages:

Noveau is an opensource nvidia accelerated driver.

So I decied to remove xserver-xorg-video-nouveau and reinstalled proprietary driver nvidia-current.

Now the system is suspendable and wakeable again.

  • I think this is slightly different. My system dies completely, and I cannot get to a console. I was already using a prop. driver, but there was a newer one available so I updated that. No difference unfortunately, it still fails to resume.
