Ubuntu switches to low-graphics mode when left unattended for some specific time

[etdsbastar]

Hello Friends,

When I leave my computer and later return, depending on how long I've been away, I find the screen-saver running, the screen turned off, or the computer suspended, i get the error as specified below on a black screen:

Ubuntu is running in low-graphics mode.

Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself.

The message gives several options. Despite some experimentals, The only solution which I have found is to reboot and everything becomes fine as before.

Do you have any idea what is happening or, better, how to fix it?

I have Lucid 10.04.

I get the same problem with an Intel GMA 3100 video card, but I've noticed (and I'm still testing) that if I leave just Rythmnbox running, it won't do this. I left Thunderbird running last night with no issues this morning.

I think it might have something to do with Firefox, as it has seemed to fail immediately after turning the screen off if I leave Firefox open.

I also turned off the "password protection" on the screen saver to see if that helped (not by itself)

Can you see if your experience is similar? I'm on a desktop.

I'm also experiencing this problem as well. Its quite annoying. Has anyone confirmed that FireFox is causing the problem? I'm not 100% i'm leaving it open, but its a good possibility.

Something must be repeatedly crashing your xserver . . . .


Can you check your log files for your xservers and see if anythings popping up there ? ideally, see if anythings common to the the guys having this problem.

I wouldnt rule out the highly-fancy-3d-screen savers even, some of them used to make the processor work surprisingly hard. . .. try and go for a blank screensaver and see if that cures it.
