NVidia and hibernation issue, partially solved


In my previous post, I mentioned about NVidia and xcompmgr, it is not true reason that causes the Chrome not updating the display.

The root cause is partially found. The issue is caused by the optimus laptop (dual graphic card, NVidia with Intel). In unknown conditions, resume from hibernation will cause the Intel graphic card doesn’t work properly. This can be checked by running “glxgears” after resume. You will see the OpenGL fails to refresh on the display.

However, if installed bumblebee, then we can run “optirun glxgears”, and this solves the graphic card issue.

Children process

Now, there is a tricky issue. because I use GNOME-Do, it is not started with “optirun”, as a result, launching the application through GNOME-Do doesn’t use the NVidia graphic card. As a result, I need to quit GNOME-Do and start it with “optirun”. So, all the application launched by GNOME-Do will use the grphic card correctly.

Run with NVidia only

Unfortunately, I experienced failing to start the X window with NVidia graphic card only. And I didn’t disable Intel graphic card, because it becomes a waste for an optimus laptop. As a result, I cannot confirm whether if only using NVidia graphic card, will the display refresh issue exist.

But so far, I use the “optirun” to run the application, if the graphic card fails to refresh the display.
