LinuxQuestions.org - [SOLVED] system freezes after power saver mode kicks in on desktop

system freezes after power saver mode kicks in on desktop

whenever desktop screensaver mode times out, it seems the power saver mode crashes
I get this on a black screen
[21.254193][drm:drm_crtc_helper_set_config] error failed to set mode on [crtc:10]

no key combo will unfreeze it, I have to turn off the power supply and when I plug in power the computer power light is on and it reboots

tried a few searches but no hits

Here a possible explanation about what is going on:

Quote:

original link Here's a better dmesg, however instead of being CTRC 5 and 6; they are 9 and 10 (and so the error is "*ERROR* failed to set mode on [CRTC:10]"). CRTC:9 is the VGA output, and CRTC:10 is the TV output. However, this card (an NV4E - GeForce 6150 LE - integrated onto the motherboard) HAS no TV output (or a DVI output either, which is also detected). So CRTC:10 is connected to a phantom output. Curiously enough, the framebuffer has a physical resolution of CRTC:9 (the VGA), but a virtual resolution of CRTC:10 (the phantom TV output) - so it only fills part of the screen.

Here another thread here in the LQ with about same problem:

And here some possible solution or at least some lights on the matter:

I don't think the computer is totally froze, have you tried ctrl+alt+(F1-F6) ? It will drop you to the virtual consoles.
From there you can kill the frozen processes and restart the login manager and GUI.
I would turn off the screensaver/power saving to avoid this issue, so you can manage the problem without having things freezing.

Which video driver is currently loading? nouveau ? And which kernel is running there? Seen like nouveau is the problem here.

*sorry did not mean to post all that, but maybe it helps determine cause of problem.
kernel is linux 3.5.0-17 generic (x86_64)

checked out the links you supplied.

for now I will just disable powersaver mode.

forgot to confirm that ctrl+alt+f1 to f6 or any other key combo does not unfreeze it

will turn off power save mode for quick fix
Power management preferences: Display/ put display to sleep: Never

I will mark this post as 'solved' but admit I took the lazy way out...
in mint 14, I opened Power Management Preferences, selected the 'On AC Power' tab and for both Actions and Displays, I selected NEVER (put to sleep when inactive for: Never)

so the problem is not really fixed but worked around.
I get basicly the same complaint...[drm:drm_crtc_helper_set_config] error failed to set mode on [crtc:10] when I power down the computer but at least it does not hang like it does for power saving mode.

I will attempt a true fix at some later date...thanks.

You should remove nouveau and install a proper nvidia driver to fix the problem for good.

Switch mint flavor.

This is an old thread but I had this problem recently on an Dell Optiplex 7040 running mint 18.1 xfce. I could not find anything on the web that fixed the problem. However, the problem went away when I switched to mint 18.1 cinnamon ....
