Nvidia graphics problem with suspend and resume, system hangs

Question

Am on 11.04. When I close my laptop lid (NVIDIA graphics - HP Pavilion) it goes onto sleep mode. But when I reopen it, instead of resuming onto the password prompt, it shows me a screen of random blocky colours - typically largely yellow. I have to do a hard reset to restart the PC. Here is an image I took of the problem:

Would file it on launchpad but not sure if it is a bug or isolated.

Thanks for any help.

Solution 1

Does that pointer move ? Is numlock light blinking ? Are you running unity or gnome ?

here is some howto for debugging problems with suspend

Solution 2

I just solved this for myself. I was having the same behavior, plus issues with Twinview. I found I was running the version 173 of the Nvidia driver, not the current recommended version.

My setup:

• Dell Latitude e6400
• Nvidia Quadro NVS 160M
• Using Twinview (but reproduces without Twinview too)

First, execute the following command:

~$ cat /proc/driver/nvidia/version

NVRM version: NVIDIA UNIX x86 Kernel Module 270.41.06 Mon Apr 18 14:54:25 PDT 2011 GCC version: gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4)

If you see 173.x.x or 185.x.x or something you are out of date.

1. Open the Unity Dash (or something like System/Admininistration in Gnome)
2. Type "Additional Drivers" and select the app (or find the menu item in Gnome)
3. It should bring up a couple of entries for your Nvidia card. Install the "current version".
4. Reboot your machine

Things perform better for me after doing this, but not perfect.

Also, I found that I could also avoid this problem by logging in to the "Ubuntu Classic (no effects)" window manager. If you are really stuck, that may be your best option.

The cursor does move. The numlock light doesn't blink but will switch on or off if I press the button. I am running unity.

so, it is not problem with kernel panic. System resumes, but there is problem either with graphic driver or unity. Can you try running classic gnome panel session ( on login choose ubuntu classic ) ?
